UNPACKING AND SETUP

Packed with your T 773 A/V Receiver you will find:

• An AM loop antenna• A FM ribbon-wire antenna with balun• A removable AC cable (if you wish, any IEC-standard AC cable of suitable wattage may be substituted).• The HTR 2 remote control with 4 (four) AAA batteries.• The ZR 2 zone remote control with 3V CR2025 battery.• This owner’s manual.

Save the packagingPlease save the box and all of the packaging in which your T 773 arrived. Should you move or otherwiseneed to transport your A/V Receiver, this is by far the safest container in which to do so. We’ve seen toomany otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Savethat box!

Choose a location that is well ventilated (with at least several inches to both sides and behind), and that willprovide a clear line of sight, within 25 feet/8 meters, between the A/V Receiver’s front panel and yourprimary listening/viewing position—this will ensure reliable infrared remote control communications. The T773 generates a modest amount of heat, but nothing that should trouble adjacent components. It isperfectly possible to stack the T 773 atop other components, but the reverse usually should be avoided.Nonetheless, it is generally preferable that the T 773 stand alone. It is especially important that sufficientventilation be provided; if you are contemplating locating the T 773 within a cabinet or other furniture,consult your NAD audio/video specialist for advice on providing adequate airflow.

ABOUT THE T 773

Though the T 773 is among the most technically sophisticated A/V Receiver, we worked hard to make it oneof the most musically transparent home-theater components available as well; this is what we mean byNAD’s “Music First” design philosophy. Here are just a few examples:

• The T 773 uses NAD’s proprietary Power Drive™ amplifier technology for all channels to preserveaccurate, linear reproduction regardless of the loudspeaker. This uniquely efficient power-supply topol-ogy provides the real-world benefits of high dynamic power that remains uncompromised by low-impedance speakers. The result is dynamic, detailed, “un-receiver-like” sound in stereo and multi-channel modes alike. NAD’s exclusive Soft Clipping™ circuitry further enhances sound quality anddynamic potential.

• High-performance components used throughout the A/V Receiver’s analog audio circuits maximize qualityfrom all sources, including multi-channel analog sources such as DVD-Audio and SACD.

• Preamp output (all channels) and main-amp input jacks make potential expansion as flexible as possible.

• A Second set of Speaker terminals (Speakers B) for remote listening.

• Second Zone (MULTISOURCE) pre-amp and video feed with assignable 12 V DC trigger control.

• An RS-232 port for advanced zone control and software update through a Windows® compatible PC.

• Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.

A key element of the T 773’s unique musical aptitude is NAD’s proprietary Enhanced Ambience RecoverySystem (EARS). In sharp contrast to many “ambience-synthesis” music-surround modes, EARS exploits theT 773’s substantial DSP power to route the ambient content that is “encrypted” in virtually all natural-acoustic recordings to the appropriate main, center and surround speakers, without resorting to artificiallygenerated reflections or regeneration. EARS’ natural ambience yields a subtle but exceptionally effectivesurround mode that naturally enhances the spatial presentation in a fashion suitable for serious musiclistening. The T 773 also incorporates a second proprietary surround mode, Matrix 7.1. This creates a full6.1/7.1-channel environment from stereo and surround-encoded recordings, oftentimes with extraordinarilygood results. Dolby ProLogic II Music and DTS Neo:6 Music modes can also create enjoyable experiencefrom 2-channel sources.

On the digital side, the T 773 combines extraordinarily high-speed DSP processing employing one of the mostadvanced high-speed DSP “engines” available, with fully 24-bit, 192 kHz-sampling-capable D/A convertersfor all channels. A single, high-precision master clock synchronizes all digital circuits to eliminate the timingerrors (“jitter”) that otherwise compromise sonics. The result is legitimately state-of-the-art surrounddecoding from Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with genuinely superiorsound quality in all modes.

Despite the effort NAD has invested in the T 773 A/V Receiver’s sonic performance, we expended no lessin making it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and theHTR 2 universal remote control is equally understandable, as are the T 773’s own front-panel and on-screendisplays. Its simple yet powerful system of “presets” permits you to fine-tune your listening setup fordifferent conditions, sources, or listeners, and to recall these multiple parameters with a single keypress.

The T 773 A/V Receiver offers extensive, flexible system-integration options through its configurable DCtrigger outputs and input, and its standard-protocol IR communications links. The DC trigger outputs can beassigned to either Local and/or Zone locations.

The T 773 A/V Receiver is equipped with a full second Zone control through the ZR 2 remote and the useof Video and pre-amp level audio outputs. Complete access to volume, On/Off, all inputs including the localinput is available.

Flexible system configuration is possible with the RS-232 interface and NAD’s proprietary Windows®compatible software. This interface allows complete remote control of the T 773 from any remote locationvia the PC. Complete remote control functionality is available to the user by interface software. See yourNAD audio specialist for further information.

1 STANDBY SWITCH: Pressing this key, or the HTR 2 remote’s [ON] button, will switch the A/V Receiver on, making it operational, changing the amberStandby indicator to green and illuminating the VFL display.

2 STANDBY LED: Illuminates amber when the T 773 is in Standby mode; green when it is powered on; and flashes momentarily to indicate infraredcommands received from the HTR 2 remote. Protection Mode is indicated by a red illumination, and indicates that there is a problem with your set-up or the unit itself. When the fault is removed, normal operation can be resumed (this may require turning the unit off and on again). This indicatorwill be steadily dark only when POWER is switched off (or the A/V Receiver is unplugged from the AC supply).

3 AM/FM: Press to toggle between the tuner’s AM and FM bands.

4 DISPLAY: Press to display the channel mode of the currently selected source (other than the internal AM/FM tuner), in the format “front/rear/LFE.”For example, a Dolby Digital or DTS 5.1-channel source will display 3/2.1. Note that the display shows signal channels, not speakers; for example,a 2-channel analog or digital source (whether stereo or surround-encoded) will show 2/0.0, even though the A/V Receiver’s <Speaker Settings> mayindeed be set up to use the subwoofer with all sources, and the current Listening Mode may employ center and surround speakers.

When the AM/FM tuner is the selected input, sequentially pressing DISPLAY shows the currently tuned station’s RDS data, toggling between thecurrent station’s Radio Text and Station Name displays (see Listening to Radio, below).

5 MEMORY: Use to store tuned stations to the T 773’s 40 preset-memory locations. (See “Listening to Radio,” below.)

6 FM MUTE/MODE: In the normal Mute position, only the stations with a strong signal can be listened to, and the noise between stations is muted.Pressing the [FM Mute/Mode] button allows distant (and potentially noisy) stations to be received. (See “Listening to Radio,” below.)

7 PRESET : Press to step up or down between radio presets; 30 FM and 10 AM station presets are available. Note that this function “wraps”:Pressing will step from Preset 30 to Preset 1, or vice versa using the key. “Unused” presets are skipped over. (Note that Presets must previouslyhave been stored; see “Listening to Radio,” below.)

8 SEARCH : Press momentarily to step up or down between FM or AM frequencies. Press and hold SEARCH for more than 2 seconds tosearch up or down; the T 773’s tuner will stop at the next sufficiently strong signal it encounters. Note that this function, too, “wraps,” and willcontinue searching up or down from one end of the AM or FM band to the other.

Note that: SEARCH tunes the FM band by 0.05 MHz steps (twice the precision of most tuners and A/V Receiver). On the AM band,SEARCH moves by 10 kHz or 9 kHz steps. To change the step amount, hold in the FM MUTE/MODE and AM/FM keys simultaneously.

9 VFL DISPLAY: The Vacuum Fluorescent Display provides visual information on all of the T773’s important modes, settings, and functions for bothMAIN and second ZONE locations.

10 VOLUME (SETUP): Turn clockwise to increase the master-volume setting; counterclockwise to lower it. The VFL and on-screen displays show thesetting, displayed in decibels between –74 and +18.

ATTENTION!Please make all connections to your T 773 A/V Receiver with the unit powered off or unplugged. (It is also advisable to power-down or unplug allassociated components while making or breaking any signal or AC power connections.)

1 FM & AM ANTENNA: The supplied wire “dipole” FM antenna will connect to the FM connector using the supplied “balun” adapter. It will usuallywork best when mounted on a vertical surface such as a wall, with arms fully outstretched forming a horizontal “T” perpendicular to the origin pointof the signal. Experiment with placement and orientation of to yield the clearest sound and lowest background noise. In areas of difficult FMreception an external FM antenna can yield dramatic gains in quality; consult your NAD audio specialist or a professional antenna installer.

The AM loop antenna supplied with the T 773 (or a suitable replacement) is required for AM reception. Open the clip terminal lever, insert the wireand close, ensuring that the lever locks the wire in place. Testing different positions for the antenna may improve reception; vertical orientation willusually produce the best results. Antenna proximity to large metal objects (appliances; radiators) may impair reception, as will attempts to lengthenthe wire to the loop.

NOTE: An external AM antenna can improve long-distance reception substantially; consult your NAD audio specialist or a professional antennainstaller. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna.

2 IR: These mini-jacks accept and output remote-control codes in electrical format, using industry-standard protocols, for use with “IR-repeater” andmulti-room systems and related technologies. Consult your NAD audio specialist for more information.

3 +12V TRIGGER IN/OUT:TRIGGER IN connects to the 12-volt trigger outputs of compatible components such as power controllers and home automation devices. The TRIGGERAUTO/OFF switch selects the 12V Trigger Input and disables the remote and front panel ON function.

TRIGGER OUT connects to 12V Input of compatible devices (such as amplifiers and projector-lifts) to automate turn on/off or activation. See “TriggerSetup”, your NAD audio specialist also can provide more information on using the T 773’s triggers.

AUTO TRIGGER SWITCH when in the AUTO position, forces the T 773 to turn on only when a trigger signal is present at the trigger input. When inthe OFF position, the trigger inputs are disabled.

4 SOFT CLIPPING: Enables NAD’s proprietary Soft Clipping circuitry on all channels. Soft Clipping gently limits the output of the T 773 to minimizeaudible distortion, even should the A/V Receiver be over-driven.

NOTE: Soft Clipping may simply be left on at all times to reduce the likelihood of audible distortion from excessive volume settings. However, forcritical listening, to preserve optimum dynamics you may wish to defeat it by setting this switch off.

5 MS OUT (MULTISOURCE OUT): Connect this pre-amp and composite video output to other zones using high-quality patch cables to reduce noisepickup over long distance runs.

6 MONITOR OUT: Connect to video input of the monitor/television, using quality dual-RCA and/or S-Video cables designed for video signals. In general,the S-Video connection is superior and should be used if your TV/monitor provides the corresponding input.

7 CD: Connect the analog stereo audio output from a CD player or other line-level audio source to this input.

8 COMPONENT VIDEO IN 1-3; OUT: Connect the COMPONENT VIDEO IN 1, 2 and 3 inputs to component-video outputs from compatible sourcecomponents, typically a DVD player and terrestrial or satellite HDTV tuner. Connect the T 773 COMPONENT VIDEO OUT to the component-video inputof a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Cr/Cb jacks (some source and TV components label these Y/Pb/Pr) to the corresponding sources/inputs; do not rely purely on the color-coding of the jacks, which may not always be consistent among brands.The routing of the component-video inputs is fixed: COMPONENT VIDEO IN 1 is routed to the COMPONENT VIDEO OUT jacks when the DVD inputis selected; COMPONENT VIDEO IN 2 is selected when the SAT input is active; COMPONENT VIDEO IN 3 is selected when the VCR input is active; theaudio and digital inputs assigned to DVD, SAT and VCR will be used (see also, "Input Setup," below).

NOTE: The T 773’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 773 does not display itson-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection betweenthe T 773 and the monitor/TV, and select it for menu display.

9 DIGITAL IN OPT 1-2; COAX 3-6: Connect to the coaxial S/PDIF-format digital outputs of sources such as CD or DVD players, HDTV or satellitetuners, or other components; connect DIGITAL IN OPT1-2 to optical S/PDIF-format digital outputs.

DIGITAL OUT: Connect the optical and/or coaxial DIGITAL OUT ports to the corresponding S/PDIF digital input of a recording component such asa CD recorder, DAT deck, or computer soundcard. See "Setting Up the T 773", below.

10 RS-232: Connect this interface via RS-232 serial cable (not supplied) to any Windows® compatible PC to allow remote control of the T 773 throughNAD’s proprietary PC software. See your NAD audio specialist for more information.

11 POWER: Press in to switch the A/V Receiver to standby mode. Pressing POWER again turns the unit OFF, recommended if you do not plan to useyour A/V Receiver for an extended period of time. It is usual (and perfectly acceptable) to leave the T 773 in Standby mode in between normalviewing and listening sessions.

12 SWITCHED AC OUTLET: This convenience jack can supply switched power to another component or accessory. It is powered on and off by thefront panel POWER SWITCH (or the HTR2’s [On] and [Off] keys).

NOTE: The total draw of all devices connected to this jack must not exceed 120 watts.

13 AC POWER INLET: Connect to the supplied IEC-standard removable AC power cord or a compatible cord.

14 SPEAKERS A & B: Connect the left and right front, centre, left and right surround, and surround back speaker outputs to the correspondingloudspeakers. Each output’s “+” (red) terminal and “-“ (black) terminal must be connected to the corresponding “+” and “-“ terminals of theloudspeaker. Use extra care to ensure that no stray wires or strands cross between posts or terminals at either end.

Connect Speakers B left and right speaker outputs to the corresponding remote loudspeakers. When speakers B are activated the output is takenfrom the front left and right channels and any signal source is converted “downmixed” to stereo as indicated in the florescent display.

NOTE: Use stranded wire of at least 16 gauge (AWG); specialized speaker cable may be valuable (consult your NAD audio specialist). Connectionsto the T 773 can be made with banana plugs (US model only), or using bare wire, or pins, by loosening the terminal’s plastic nut, making a clean,neat connection, and re-tightening carefully (use the transverse hole through the post for bare-wire or pin connections). To minimize the dangerof short-circuits, ensure that only 1/2-inch of exposed wire or pin is employed in connecting.

NOTE: This unit is designed to produce optimum sound quality when connected to speakers with impedances within the A/V Receiver’s operatingrange. Please check front, center, and surround speakers are rated to be 4Ω min. per speaker.

IMPORTANT NOTE: For optimum surround performance, the T 773 speaker settings and levels must be set correctly via the A/V Receiver’s setuproutines; see “Setting Up the T 773”, below.

15 DVD, SAT, VCR, VIDEO 4, VIDEO 5: These comprise the T 773’s principal inputs. Connect S-Video, composite video, and analog stereo audio fromsource components such as DVD players and HDTV/satellite tuners (see "Input Setup," below). VCR and VIDEO 4 may be used with recordingcomponents such as videocassette or DVD-recorders; connect the T 773 S-Video/composite video OUT jacks to these components’ record-inputs.(Note that VCR/VIDEO 4 may freely be used for play-only components, in which case their OUT jacks would remain unconnected.)

16 MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT: The T 773’s 7 built-in power amplifier channels will deliver excellent quality with even verydemanding, low sensitivity home-theatre speaker systems. However, it is also possible to use the T 773 as a pre-amplifier with external poweramplifiers for some or all channels (remove the supplied jumpers) if necessary. Unlike the six full range channels, there is no power amplifier built-into the T 773 for a subwoofer.

Connect the SW output 1, 2 or both to powered (“active”) subwoofers (or to power amplifier channels driving a passive system).

SURR-BACK-R jack will supply the same signal from the surround-back Left channel if the T 773 is so configured (see “Speaker Setup,” below).Either one or both channels are available mono or stereo as per “Speaker Setup”. Your NAD audio specialist will be happy to advise you.

NOTE: Never connect the T 773’s speaker outputs and the speaker outputs of an external amplifier to the same speakers.

17 TAPE IN/OUT: Connect the T 773’s TAPE OUT jacks to the stereo analog audio inputs, of an audio recording component such as a cassette deckor CD recorder, or of an outboard analog audio processor such as a stereo equalizer; connect the A/V Receiver’s TAPE IN jacks to the component’scorresponding outputs. The signals present at the TAPE IN jacks can be heard by selecting the front panel TAPE MONITOR button, or the HTR 2’s[Tape] (zero) key.

NOTE: The signal present at the TAPE OUT jacks is determined by the source last selected via the front panel Video or Audio keys (or the HTR2’s input-select keys).

NOTE: Digital input signals are not available at the analog TAPE OUT jacks; they are only available at the DIGITAL OUT jacks.

18 DISC: Connect the analog stereo audio output from a second CD player or other line-level audio source to this input.

NOTE: Connecting a phonograph turntable to the T 773 requires an outboard magnetic phono-preamp component such as the NAD PP2; youcannot connect turntable directly to the DISC inputs.

19 7.1 CH. INPUT: Connect to the corresponding analog audio outputs of a multi-channel source component such as a DVD-Audio or multichannel-SACD player, or external multi-channel decoder. Typically, these sources will produce 5.1-channel output, in which case the SURROUND BACKjacks are left unconnected. The signals present at these jacks may be heard by selecting the front-panel EXT. 7.1 key or the HTR 2’s [Ext 7.1/5.1] button. See “Selecting Sources," below.

NOTE: There is no bass-management or other processing (other than master-volume control) available to this 7.1 CH. INPUT. While the multi-channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 773’s own Dolby Digital and DTS decoding and digital-analog converters, via a digital connection, will usually produce superior results.

SETTING UP THE T 773

Before you make the first connection to your T 773, you should have the arrangement of your listening room/home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vitalquestions of loudspeaker placement and listening/viewing positions is beyond our scope here. Suffice it tosay that these two questions will influence your system's ultimate performance every bit as powerfully asyour selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you, andto recommend reference materials.

NOTE: You will need the HTR 2 remote handset to configure your T 773. See “Using the HTR 2 Remote”,below.

Hum and noise sometimes prove a challenge in complex, multi-channel audio systems. Note these consid-erations to help prevent hum and noise problems:

• Power all your system's audio component from AC outlets originating from the same circuit of your housewiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on thesame circuit. It may be useful to power video displays (and computers!) from outlets on another circuit,especially if that circuit is supplied from the other "leg" of the house wiring.

• Do not bundle analog audio cables with AC power cables, or with coaxial digital-audio cables. It is bestif they cross at right angles if they must be in close proximity.

• Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure.

• A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low-resistancecontact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging,since the gold (or copper) contact plating of typical cable connectors, even very high-quality ones, is verythin and easily worn.

Track down hum/noise problems one component at a time, working backwards from the A/V Receiver. Thatis: Connect the speakers to the A/V Receiver only, and check for hum. Then connect one component only(a CD player, for example) alone, with no other components connected and check for hum. Connectadditional components, one at a time, to the A/V Receiver and check for hum. At each stage, if hum/noiseappears, examine the audio cabling and AC-power routing of the new component. In some cases, movingthe new component's AC cord to a different outlet, or installing a ground-lift (3-to-2-prong adapter) on itspower cord, will eliminate the hum.

The T 773 A/V Receiver employs a simple, self-explanatory system of on-screen display "menus" that willappear on the connected video monitor/TV. These are required during the setup process (and are useful inday-to-day operation), so be sure to connect the monitor/TV before proceeding with setup.

NOTE: The on-screen displays are carried on both the S-Video and composite MONITOR OUT jacks, but arenot incorporated into the component-video output.

Press any of the HTR 2 remote's central cursor keys ([ ], [ ], [ ], [ ], and [Enter]) to display the T773’s main <Setup> menu on your video monitor/TV. If the OSD does not appear, check your MONITOR OUTconnections.

NOTE: The OSD does not appear on the T 773's component-video output, nor does it appear on the VIDEO3 and 4 record-outputs; these are for recording, not monitoring.

NANANANANAVIGAVIGAVIGAVIGAVIGATING THE OSD AND MAKING CHANGESTING THE OSD AND MAKING CHANGESTING THE OSD AND MAKING CHANGESTING THE OSD AND MAKING CHANGESTING THE OSD AND MAKING CHANGESUse the HTR 2 remote's [ / ] keys to move up or down among the Setup menu's list of items; use [Enter]to select a menu item, and use [ / ] to change the parameter-value (setting) of any item. Selecting the<Save and Exit> returns "up" to the <Setup> menu while saving any parameter-value changes to the T 773’smemory; selecting <Do Not Save and Exit> also returns to the main <Setup> menu, but abandons anychanges made on the previous menu. Selecting <Exit> from the main Setup menu exits the OSD altogether,retaining parameter-value changes, if any, made previously.

The T 773 is equipped with nine configurable and nameable inputs: six audio-video inputs labeled DVD, SAT,VCR, and VIDEO 4-6 (including VIDEO 6 on the front panel), and three audio-only inputs labeled CD, DISCand EXT 7.1. These are flexibly configurable and nameable: For each labeled video input-jack position (DVD,SAT, VCR, VIDEO 4-6) as displayed on the <Video In> line of the <Input Settings> menu, you may freelyassign: an analog audio input selected on the <Audio In> line; and a digital input selected on the <DigitalIn> line. These will become active whenever that input is selected.

NOTE: An incoming digital signal present at the assigned digital input will always take precedence over theassigned analog-audio input, even if both are present. The digital signal can be temporarily selected “OFF”using the front panel DIGITAL AUDIO SELECTOR button.

NOTE: The analog input for any audio-video inputs may be set to OFF in the OSD if only Digital inputs areused.

INPUT SETTINGSINPUT SETTINGSINPUT SETTINGSINPUT SETTINGSINPUT SETTINGSFrom the main <Setup> menu, select the <Input settings> menu item using the HTR 2 remote's [ / ], and[Enter] keys. Using the [ / ] keys select the video input (DVD, SAT, VCR, VIDEO 1-6) you wish toconfigure. Use the [ / ] keys to move to the <Audio In> line, and then use the [ / ] keys to selectthe analog audio input you wish to be linked to that input (usually, this will be the same, i.e., “DVD” with“DVD,” “Video 4” with “Video 4,” and so on).

NOTE: It is not necessary to have an analog audio input connected for every video input you employ. In fact,in some cases—for example for a DVD player—it may be preferable to make only a coaxial or optical digitalaudio link to the T 773 for audio playback. This avoids possible confusion, and ensures that the T 773’s high-performance surround and digital audio circuitry will always be employed.

Now use the [ / ] keys to move to the <Digital In> line and select the digital input (“Opt 1-2,” “Coax 1-4”) you wish linked to that input.You may also select Analog OFF for this audio-video input so that only thedigital input is active.

If you set <Digital In> to “Off,” no incoming digital signal will be selected by that input. (Set an input’s<Digital in> to “Off” only if you wish to ensure that that input will not play an incoming digital bitstream,even if one is present.). At this point you may wish to fine adjust the analog input gain; for each audio-video input from -12 dB to + 12 dB of adjustment.

NOTE: The <Trigger Out:> line of the <Input Settings> menu is used to configure the T 773’s 12-volt trigger.See “Trigger Setup,” below.

The component-video inputs are not configurable. Selecting the DVD input routes the COMPONENT VIDEOIN 1 to the COMPONENT VIDEO OUT jacks; selecting VCR routes the COMPONENT VIDEO IN 3 to theCOMPONENT VIDEO OUT jacks. Note that the OSD does not appear on the component-video output.

NOTE THAT: The combination of analog-audio input and digital input assigned above will always be recalledwhenever that input is selected via the front-panel VIDEO key, or the HTR 2 remote’s input-select keys, orby recalling a Preset;

The digital and analog audio inputs assigned to a video input can be overridden by using the front-panelAUDIO and DIGITAL AUDIO SELECTOR keys; however, the assigned input will return whenever that videoinput is reselected, either via the front panel VIDEO key or using the HTR 2’s input-select keys (or a Preset);

The TAPE MONITOR loop is not configurable, and will not appear in the rotation;

Any audio input and any digital input may be configured with any video input, and the same analog and/ordigital inputs may be assigned to multiple video inputs;

The analog audio input selected on the <Audio In> line is also routed to the TAPE OUT jacks.NOTE: That signals from digital inputs are not available on the analog TAPE OUT jacks.

LISTENING MODELISTENING MODELISTENING MODELISTENING MODELISTENING MODE

Every surround-sound system requires "bass-management" to direct low-frequency content from any or allchannels to the speakers best able to reproduce it. For this function to operate correctly, it is important thatyou correctly identify your speakers' capabilities.We use the terms "Small" and "Large" (and "Off"), but note that physical size may be irrelevant.• A "Small" speaker is any model, regardless of physical size, that lacks significant deep-bass response,

that is, below about 80 Hz.

• A "Large" speaker is any full-range model, that is, one with deep-bass response

• An "Off" speaker is one that is not present in your system. For example, you might not have any surround-back speakers installed; in that case, you would set the <Surr Back> setup item to "OFF".

Depending on the relationship between speakers, the possible selections for each speaker are as follows:

Adjusting the relative balance of your system's loudspeakers ensures that surround-sound recordings,whether music or film, will present the balance of effects, music, and dialog that the artists intended.Additionally, if your system incorporates a subwoofer it establishes a correct relationship between thevolume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonicelements.

USING AN SPL METERUSING AN SPL METERUSING AN SPL METERUSING AN SPL METERUSING AN SPL METERIt is quite practical to perform the T 773 Level setup routines "by ear," and careful work will produceacceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter, such asRadio Shack part number 33-2050, makes this task easier, more accurate and more repeatable. Ownershipof such a meter could prove a valuable audio tool; your NAD audio specialist may be able to help you withtemporary use of a meter.

The SPL meter should be placed at the primary listening position, at approximately the height of the seatedlistener's head. A tripod is helpful, but with a little duct tape almost anything — a pole lamp, music-stand,or ladder-backed chair, for example — can do as well. Just be sure that no large acoustically reflectivesurfaces obstruct or are near the microphone element. Orient the meter with its microphone (usually at oneend) pointing straight up toward the ceiling (not forward toward the speakers) and ensure that its "C"weighting scale is selected. Set the meter to display 75 dB SPL. (On Radio Shack meters this necessitateseither setting the meter to its 80 dB range and taking your readings at the -5 point, or selecting the 70 dBrange and reading at the +5 point.)

SETTING CHANNEL BALANCESETTING CHANNEL BALANCESETTING CHANNEL BALANCESETTING CHANNEL BALANCESETTING CHANNEL BALANCEPress the HTR 2 remote’s [Test] key, activating the T 773’s channel-balancing test signal and displaying the<Channel Levels> menu on the OSD. You will hear a "surf" sound that cycles through your speakers,beginning with the left-front. (If you do not hear the test signal, check your speaker connections (above),and your <Speaker settings> OSD menu settings, (above.)

As the test signal cycles around the speakers, the OSD (and the VFL front panel display) will highlight thecurrently playing channel. Now use the remote's [ / ] keys to adjust the loudness of the noise outputfrom the currently playing channel to the required level (it’s usually simplest to begin with the left-front). The"level offset" reading on the right will change by 1 dB increments; ±12 dB adjustment is available.NOTE: If you are balancing levels "by ear", choose one speaker—usually the center—as a reference andadjust each of the others in turn to "sound as loud" as the reference. Be sure that you remain in the primarylistening position while balancing all channels.

Using the remote's [ / ] and [ / ] keys adjust each speaker to produce the same SPL meter reading(or subjective loudness). Note that:• All speakers must be in their final locations before level-setting.• Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its

highest-possible frequency if you are using the T 773's SUBWOOFER output. Final subwoofer-leveladjustment “by-ear,” using music and film sound material, is frequently useful.

• Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not alwayscalibrate to exactly the same level offset readings.

Your system's speaker distance settings are a subtle but important refinement of your setup.

CREATING AND USING PRESETSThe T 773’s simple but powerfully flexible system of “Presets” allows you to customize virtually every aspectof your audio-video playback, and recall them with a single key-press. Every parameter of T 773 operationthat is available from the main <Setup> menu — input settings, level settings, delay settings, speakersettings, and listening mode selection and adjustments — is stored, together, as a single Preset. You mightcreate one Preset optimized for pop music and another for classical, or Presets that recall each familymember’s favorite setup, or one for fully cinematic home-theater playback and another for late-nightmovies, with each Preset’s surround mode, channel levels, and speaker-setup fine-tuned to a particularscenario or preference.

CREACREACREACREACREATING PRESETSTING PRESETSTING PRESETSTING PRESETSTING PRESETSCreating a Preset consists simply of storing a complete set of all settings accessible from the main <Setup>menu, including Tone Control settings. To save a collection of settings to a Preset, use the HTR 2 remote’s[ / ] keys to scroll to the to main <Save to Preset> item. Use [ / ] to scroll to the desired Preset’s line[1-5]; <Stored> will be flashing. Now press the HTR 2’s [Enter] to store the Preset; <Stored> will be stopflashing, confirming that the Preset has been stored.

NOTE: The selected Preset remains in force until you select a different Preset.

NOTE: It is strongly recommended to leave Preset 1 “empty”; that is, memorized with no changes at allmade to the calibrated values you have entered on all of the <Setup> menu lines. This will make returningto your calibrated setup defaults easy.

RECALLING PRESETSRECALLING PRESETSRECALLING PRESETSRECALLING PRESETSRECALLING PRESETSYou may recall a Preset at any time; the newly recalled Preset will replace the previous Preset (if any).Presets can only be recalled using the HTR 2 remote:Press the HTR 2’s square [A/V Preset] key (red dot), then press the numeric key 1-5 corresponding to thedesired preset.

NOTE: The [A/V Preset] key works as a momentary “shift” key: You must press it every time before invokinga Preset via a numeric key.

USING THE T 773

You may operate the T 773 A/V Receiver from its front panel or via the HTR 2 remote control. Since theremote will be the primary controller for most cases, we will focus on remote-controlled operations. Be surealso to read the section, "Front Panel" above.

With the HTR 2’s remote's [Amp] device selected, the remote’s numeric-key section directly selects the A/V Receiver’s inputs, plus the internal tuner ([Tuner), Tape Monitor ([Tape]), and multi-channel input ([Ext.7.1/5.1]) refer to the red labels directly above each key.

• When an audio-only source (CD, DISC, TUNER) is selected, the most recently-selected video signalremains selected, until another audio-video input is selected

• When you change sources, the VFL will display the new input in its primary display.

• A newly selected input's listening mode (Stereo, EARS, Pro Logic II, etc.) will revert to the mode to whichit is configured on the <Input Settings> line of the setup menu, unless the incoming signal is a DolbyDigital or DTS source, in which case the input will be set automatically to the appropriate decoding mode.

Use the HTR 2 remote's <Volume up/down> keys to adjust the "master volume" of the T 773, raising orlower all channels together. Note that:

• A momentary keypress will change the master volume by 1 dB increments; if you hold down <Volume up/down> the master-volume change will "run-on" until the key is released.

• The T 773's OSD will show the volume setting as a line graphic with a numeric display above in dB relativeto the reference level.

Since recordings vary considerably in overall average level, there is no imperative to listen at any particularmaster-volume setting. A setting of -20 may sound "as loud" from one CD or DVD as -10 does from another.

• If muting has been activated (below), adjusting master-volume via the HTR 2 remote or the front-panelknob automatically releases the mute function.

• The T 773 will power-up from Standby mode at whatever master volume setting was last used; however,if the prior setting was greater than –20 dB the T 773 will power up to –20 dB. This prevents inadvertentlybeginning a session at excessive volume.

MUTING THE SOUNDMUTING THE SOUNDMUTING THE SOUNDMUTING THE SOUNDMUTING THE SOUNDUse the HTR 2 remote's <Mute> key to silence all channels completely. Muting is always available,regardless of source or listening mode selections. Note that:

• Cycling through Standby or powering off does not release muting; the T 773 will return from Standby withmuting on if Standby was invoked with muting on.

• Changing input or listening-mode selections does not release muting.

• Adjusting the master-volume upward via the HTR 2 or the front-panel knob automatically releases themute function.

The T 773’s internal AM/FM tuner offers very high quality sound from radio broadcasts. Note that receptionand sound quality will always be dependent to a degree on the type of antenna(s) used, as well as proximityto the broadcast origin, geography, and weather conditions.

ABOUT ANTENNASABOUT ANTENNASABOUT ANTENNASABOUT ANTENNASABOUT ANTENNASThe supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the‘balun’ included adapter, and should be fully extended to form a “T”. This folded-dipole antenna will usuallywork best oriented vertically, with the arms of its “T” full outstretched and arranged perpendicular to theorigin of the desired broadcast. There are no ‘rules,’ however, and experimenting freely with antennaplacement and orientation may yield the clearest sound and lowest background noise. In areas of poor FMreception, an exterior FM antenna can improve performance dramatically. If radio listening is important toyou, consider consulting an antenna installation professional to optimize your system.

The supplied AM ‘loop’ antenna will usually provide adequate reception. However, an exterior AM antennacan be used to improve reception; consult an antenna professional for more information.

Then press theMEMORY key once again. The STORED message will appear in the VFL Display.

NOTE: The Radio Presets must be stored from the front panel; this setup function is not accessible from theHTR 2 remote.

CHOOSING THE FM MUTE / MODECHOOSING THE FM MUTE / MODECHOOSING THE FM MUTE / MODECHOOSING THE FM MUTE / MODECHOOSING THE FM MUTE / MODEThe front-panel FM MUTE/Mode key is a dual-purpose control. First, it “toggles” the T 773 between stereomute and unmated stereo reception (assuming that a multiplex-stereo station of sufficient strength istuned). FM Mute eliminates noise from “empty” FM frequencies but also mutes very weak or distantstations; it also causes the search function to skip them. Toggling off the FM Mute will result in reducednoise if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently lessnoise-prone), though at the sacrifice of the stereo effect.

NOTE: The one can store the same channel in two preset locations; one with FM Mute On, and with FMMute Off.

NOTE: Toggling between FM Mute on or off also defeats the T 773’s FM muting circuit. If you wish to listento a particularly weak or distant broadcast, toggle off the FM Mute and tune it manually.

ABOUT RDSABOUT RDSABOUT RDSABOUT RDSABOUT RDSThe Radio Data System (RDS) permits compatible FM A/V Receiverss to display text determined by thebroadcaster. The T 773 supports two RDS modes, station-name (PS mode) and radio-text (RT mode).However, not every FM station incorporates RDS in its broadcast signal; in most areas you will find from oneto several RDS-enabled stations, but it is by no means impossible that your favorite stations will not bebroadcasting RDS data.

DTS DIGITDTS DIGITDTS DIGITDTS DIGITDTS DIGITAL SURROUNDAL SURROUNDAL SURROUNDAL SURROUNDAL SURROUNDThe Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format thatcan process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are 5.1 channelmedia formats, discs bearing the “DTS” symbol are thought to provide better sound quality due to the loweraudio compression required.It also offers a broader dynamic, producing magnificent sound quality.

DTS - ES EXPANDED SURROUND ™ (DTS ES)DTS - ES EXPANDED SURROUND ™ (DTS ES)DTS - ES EXPANDED SURROUND ™ (DTS ES)DTS - ES EXPANDED SURROUND ™ (DTS ES)DTS - ES EXPANDED SURROUND ™ (DTS ES)This is a new multi-channel digital format which greatly improves the 360° spatial sensation of the Surroundimpression thanks to the greater space expansion of the surround signals, providing high compatibility withthe conventional DTS format.

In addition to the 5.1 channels, the expanded DTS-ES Surround also offers the back surround (alsosometimes called the “surround centre”) in reproduction, providing a total of 6.1 channels. The expandedDTS-ES Surround includes two formats, with two different methods of surround signal recording, as follows:

DTS-ES™ DISCRETE 6.1DTS-ES™ DISCRETE 6.1DTS-ES™ DISCRETE 6.1DTS-ES™ DISCRETE 6.1DTS-ES™ DISCRETE 6.1Since the signals of the 6.1 Surround channels (including the back channel) are completely independent, itis possible to achieve the sensation that the acoustic image is moving about freely among the backgroundsounds, 360 degrees surrounding the listener.

Although maximum quality is achieved with sound tracks recorded using this system and reproduced usingthe DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel is automati-cally downmixed in the surround right and surround left channels of the surround system, in such a way thatnone of the signal components are lost.

DTS - ES™ MADTS - ES™ MADTS - ES™ MADTS - ES™ MADTS - ES™ MATRIX 6.1TRIX 6.1TRIX 6.1TRIX 6.1TRIX 6.1In this format, the additional signals of the back channel receive a matrix encoding and are inputted into theright and left surround channels. During reproduction they are decoded to the right, left and back surroundchannels.

Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1format effect can also be achieved from sources with DTS-ES 5.1 signals.Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in DTS-ES 6.1.When a DTS-ES decoder processes decodes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats areautomatically detected and the Optimum Surround mode is selected.However, some DTS-ES Matrix 6.1 sources may be detected as DTS. In this case the DTS-ES Matrix modeshould be selected manually in order to reproduce them.

DTS NEO: 6™ SURROUNDDTS NEO: 6™ SURROUNDDTS NEO: 6™ SURROUNDDTS NEO: 6™ SURROUNDDTS NEO: 6™ SURROUNDThis mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to thehigh precision digital matrix decoder used for DTS-ES Matrix 6.1, to achieve 6.1-channel surround playback.DTS Neo: 6 surround includes two modes for selecting the optimum decoding of the signal sources:

DTS NEO: 6 CINEMADTS NEO: 6 CINEMADTS NEO: 6 CINEMADTS NEO: 6 CINEMADTS NEO: 6 CINEMAThis method is ideal for the reproduction of movies. The decoding takes place by emphasising the separationin order to achieve the same atmosphere with 2-channel, as with 6.1-channel sources.

DTS NEO: 6 MUSICDTS NEO: 6 MUSICDTS NEO: 6 MUSICDTS NEO: 6 MUSICDTS NEO: 6 MUSICMainly recommended for music reproduction. The right and left front channels do not pass through thedecoder and are reproduced directly so there is no loss in sound quality, and the effects of the rightsurround, left surround, central and back surround channels add a natural sensation of expansion of thesound field.

The T 773 A/V Receiver offers nine distinct listening modes, tailored for different types of recordings orprogram material. The table below lists which modes are available to what input signals.With a two-channel (STEREO) source the following listening modes can be selected:

• Stereo• Downmix

All output is directed to the left/right-front channels; low frequencies are directed to the subwoofer if oneis present in the Speaker settings. Select Stereo when you wish to listen to a stereo (or monaural)production, such as a music CD or FM broadcast, without surround enhancement. Stereo recordings,whether in PCM/digital or analog form and whether surround-encoded or not encoded, are reproducedas recorded; multi-channel digital recordings (Dolby Digital and DTS) are reproduced in “Downmix” modevia the left- and right-front channels only, as Lt/Rt (left/right-total) signals.

• Dolby Pro Logic• Dolby Pro Logic II (PLII)

Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro Logic, orProLogic II surround processing, yielding output to left-, center-, and right-front channels, and discreteleft/right surround channels (assuming these are present in the current <Speakers Setup>. PLII does notemploy the surround back speakers (if any).

NOTE: ProLogic II is a more recent evolution of the original Dolby ProLogic surround processing that yieldsmore stable imaging and full bandwidth sound to the rear channels in Movie mode, offering sound thatis more similar to Dolby Digital decoding.The T 773 provides two PLII variations: MOVIE and MUSIC. See “Adjusting Listening Modes,” below.

• DTS Neo:6Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround withoutput to left, center-, and right-front channels and discrete left/right surround channels (assuming theseare present in the current <Speakers Setup>).The T 773 provides two DTS Neo:6 variations: CINEMA and MUSIC. See “Adjusting Listening Modes,”below.

• EARSTwo-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NADsurround processing with signals output to the left, center-, and right-front channels and discrete left/right surround channels, plus subwoofer (assuming these are present in the current <Speakers Setup>);EARS does not employ the surround back speakers (if any). EARS extracts the natural ambience presentin nearly all well-produced stereo recordings. It does not synthesize any ambience or other sonic elementsand thus remains truer to the sound of the original musical performance than most other music-surroundoptions.Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highlynatural and believable ambience from nearly all "natural-acoustic" stereo recordings; typically, theseinclude classical, jazz, and folk genres as well as numerous examples from others. It's virtues include arealistic, stable "front-stage" sonic imaging and spacious but unexaggerated ambient "virtual acoustics"that remain faithful to the original recording.

• Matrix 7.1Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary surroundprocessing via the full suite of front, surround, and one or two surround back speakers (if these arepresent in the current Speaker Settings setup), plus subwoofer (if any). Matrix 7.1 can produce a verynatural, cohesive all-channels surround from high-quality recordings, both for stereo music and forsurround-encoded music or movie programs.

• Enhanced-Stereo 1 (ST1)All recordings reproduced in stereo via the maximum speaker complement configured in the current<Speakers Setup>. ST1 can be useful for maximum volume from all channels, or for multi-speakerbackground music (cocktail party) listening.

USING THE T 773

• Enhanced-Stereo 2 (ST2)All recordings reproduced in stereo via the surround speakers only (plus subwoofer, if any), assumingthese are configured in the current <Speakers Setup>. ST2 can prove useful in certain late-night or verylow-volume listening situations.

The following Surround Sound Modes require a specially encoded signal that must be present in digitalformat to be decoded by the T 773. These modes are automatically switched on when the appropriate datastream is detected selected in the setup menu of the source media.

• Dolby Digital• Dolby Digital EX• Dolby Digital Surround Sound EX• DTS• DTS ES Matrix• DTS ES 6.1

Digital recordings in Dolby Digital or DTS formats are reproduced via the channels employed in the originalrecording (up to the maximum channels present in the current <Speaker Settings> setup).

NOTE: The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. Your DVDplayer probably includes its own setup menu that (among other things) lets you select the default bit-stream format, and usually includes an “Auto” setting that directs the player to choose the Dolby Digital/DTS signal whenever these are available. In a few cases, you may have to set the player’s bit-streammanually to “DD/DTS” or an equivalent. In the case of DVDs that carry both Dolby Digital and DTS, youwill select one or the other from the disc’s (not the player’s) main menu.

Note also that while most Dolby Digital recordings are 5.1-channel surround productions, older examplesmay be multi-channel, 2-channel, or even monaural; the T 773 will automatically reproduce the DolbyDigital signal with the maximum number of channels available.

Both Dolby Digital/EX and DTS/ES 6.1-channel recordings are reproduced using the surround back channel,if present in the current Speaker Settings setup; additionally, the T 773 creates surround-back signal fromnon-EX/ES, 5.1-channel Dolby Digital and DTS recordings.

Dolby Digital EX creates six full-bandwidth output channels from any 5.1-channel Dolby Digital recordings.The very best results occur with movies or other programs bearing the Dolby Digital Surround EX mark,which are produced to take full advantage of this playback mode.

The table below indicates which listening modes are available with the two types of audio signal sources:digital- or analog-input 2-channel (whether the actual signal is monaural, stereo or surround-encoded), anddigital-multichannel (Dolby Digital or DTS). Where a listening mode is not available to a given signal source,it will not appear in the <Listening Mode> selection rotation.

USING THE HTR 2 REMOTE CONTROL

• Controls up to 8 devices.• 44 function keys.• Learns up to 352 commands.• Records up to 44 macros with a maximum of 64 commands each.• Configurable punch-through.• Key illumination with programmable timeout.• Upgradable.• Contains pre-programmed library of NAD remote codes.

The NAD HTR 2 is ready to operate the T 773 A/V Receiver right out of the box, but it is really eight remotesin one. Each of the 8 Device Selector keys at the top of the handset can call up a new “page” of remote-control codes to be transmitted by the remaining 44 keys. You may “teach” codes from any infrared-remote-controlled component, regardless of brand, to any or all of these. Obviously, the most logical system is thatyou teach the codes from your DVD player to the [DVD] Device Selector “page,” your television’s codes tothe [TV] “page,” and so on, but there is no required scheme: You may load any commands to any key onany page (see “Learning Codes From Other Remotes,” below).

The HTR 2 is already preprogrammed with a full complement of commands for the T 773 A/V Receiver on its[AMP] Device Selector page, and as well as with library commands to operate most NAD-brand DVD, CD, orTAPE components on the corresponding Device Selector “pages.” These default commands are permanent:Even if you teach the HTR 2 new commands to take their place, the underlying library commands remain inplace and can easily be recalled should you add an NAD component to your system later (see “DeleteMode”, below).

NOTE: For use with the T 773, it should not be necessary to re-program any keys on the HTR 2 [AMP]page. However, in order for the HTR 2 to control your specific NAD-brand components you may need toload one or more different code-libraries; see “Loading Code Libraries,” below.

CONTROLLING THE T 773CONTROLLING THE T 773CONTROLLING THE T 773CONTROLLING THE T 773CONTROLLING THE T 773The HTR 2 is divided into two main sections. Eight Device Selector keys at the top—[AMP], [DVD,] [TV,] andso on—set the handset’s remaining keys to a “page” of commands to control a particular component. ADevice Select key determines only what component the HTR 2 will command; it does not perform anyfunction on the A/V Receiver. All of the remaining keys are function keys that can “learn” control codes fromvirtually any infrared remote controller, allowing you to teach the codes of your equipment, regardless ofbrand, to the HTR 2.

However, the HTR 2 is already preprogrammed to operate the T 773. All of the function keys on the [AMP]Device Selector “page” perform T 773 functions. (The HTR 2 can also command many other NAD compo-nents, from its [DVD,] [CD,] [TUNER,] and [TAPE] pages.)

It is important to note that certain HTR 2 keys perform different functions depending on the selected DeviceSelector “page.” The color of the Device Selector key-labeling corresponds to the labeling of the functionkeys. Most centrally, the red [AMP] Device Selector “page” corresponds to the red input-select labelingadjacent to the numeric keys: When the HTR 2’s [AMP] Device Selector page is active, these keys select theA/V Receiver inputs. Similarly, the purple [DVD] Device Selector “page” corresponds to several purple labels,the green [TV] page to green labels, and so on.

LEARNING CODES FROM OTHER REMOTESLEARNING CODES FROM OTHER REMOTESLEARNING CODES FROM OTHER REMOTESLEARNING CODES FROM OTHER REMOTESLEARNING CODES FROM OTHER REMOTESBegin by positioning the HTR 2 “nose-to-nose” with the source remote so the two devices’ infrared windowsare about 2 inches apart.

• Enter Learning Mode: On the HTR 2, simultaneously press-and-hold for 3 seconds both a Device Selectorkey and the [•] “record” key (just below the [DISP] key), until the Learn LED at the center of the HTR 2turns steady green.

• Press the HTR 2’s function key you wish to teach a command; the Learn LED will turn amber.

• Press-and-hold the function key on the source remote: The HTR 2’s Learn LED will flicker amber for asecond or two, then turn solid green. The command is learned.

• Press the HTR 2’s Device Selector key again to exit the learning mode.

If the Learn LED does not flicker amber you may need to vary the distance between the remotes.If the Learn LED turns red rather than green, that particular command of that source remote commandcould not be learned.Cancel Operation:You can cancel configuring a key, by pressing the active Device Selector key before the learn is complete;the Learn LED will turn red.

Example: Learning “DVD Pause”:Position the HTR 2 and your DVD player’s remote as described above.• On the HTR 2, simultaneously press-and-hold [DVD] and [•]; the Learn LED turns steady green.• Press the HTR 2’s [ | | ] (pause) key; the Learn LED turns amber.• Press-and-hold the DVD player’s remote’s pause key; the HTR 2’s Learn LED flickers amber and then

turns solid green. The command is learned.• Press [DVD] again to exit the learning mode.

PUNCH-THROUGHPUNCH-THROUGHPUNCH-THROUGHPUNCH-THROUGHPUNCH-THROUGHThe HTR 2’s “punch-through” function allows you to retain a function key from one Device Select “page”on another, so that, for example, the AMP [SURR MODE] function might still control the T 773 when the DVDDevice Selector page is active

NOTE: The HTR 2’s [VOL] keys are pre-programmed as “punched-through” for all Device Select pages:[VOL] will operate the T 773’s master-volume regardless of the currently selected device. The [SURR.][CENTER,] and [SUB] Channel Volume controls similarly are pre-programmed as punched-through.

To set a punch through, after entering the Learning Mode, and pressing the desired key to be punched-through, simply press the device key twice of the device to punch through to. The status LED will turn green;press the Device Selector key again to exit Learning Mode.

Example: Punch-through the from the DVD “page” to the AMP [SURR MODE] key:• On the HTR 2, simultaneously press-and-hold [DVD] and [•] (record); the Learn LED turns steady green.• Press [SURR MODE]; the Learn LED turns amber.• Press [AMP] twice; the Learn LED turns green.• Press [DVD] again to exit the learning mode.

COPY A COMMAND FROM ANOTHER KEYCOPY A COMMAND FROM ANOTHER KEYCOPY A COMMAND FROM ANOTHER KEYCOPY A COMMAND FROM ANOTHER KEYCOPY A COMMAND FROM ANOTHER KEYYou may copy a command from any HTR 2 key to any other. To copy a key function, after entering theLearning Mode, and pressing the desired key to be copied to, simply press the device key from which youwish to copy, having first pressed its Device Selector key if it resides on another “page.” The status LED willturn green; press the Device Selector key again to exit Learning Mode.

Example: Copy the Pause command from the CD page to the AMP [ | | ] key:• On the HTR 2, simultaneously press-and-hold [AMP] and [•] (record); the Learn LED turns steady green.• Press [ | | ] (pause); the Learn LED turns amber.• Press [CD]; press [ | | ] (pause); the Learn LED turns green.• Press [AMP] again to exit the learning mode.

NOTE: The copy and punch-through functions are similar. However, if you copy a command and thensubsequently delete, or over-write the original (source-key) command , the copied-to key’s commandremains unchanged. If you punch-through to a command and then delete or over-write the original key,the punched-through functions also change accordingly.

MACRO COMMANDSMACRO COMMANDSMACRO COMMANDSMACRO COMMANDSMACRO COMMANDSA “macro” command is a series of two or more remote codes issued automatically from a single keypress.You might use a macro to automate a simple command sequence, such as, “Turn on the DVD player and thenpress ‘play.’” Or you might compose an elaborate macro to power up an entire system, select a source,choose a Listening Mode, and begin playback—again, all from a single keypress. The HTR 2 can store onemacro on each of its function keys (these exclude the Device Selector keys).

NOTE: Macros are independent of the currently selected device.

RECORDING MACROSRECORDING MACROSRECORDING MACROSRECORDING MACROSRECORDING MACROSTo record a macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR 2function key to which you wish to assign the macro, until the status LED turns green. The macro button willalso light up. Press the sequence of function keys to be recorded into the macro, being sure to first pressthe requisite Device Selector key for each function (you may switch devices while recording the macro asmany times as necessary), allowing you to create macro containing commands from more than one DeviceSelector “page.” When you have finished entering the desired command sequence, press [MACRO] againto store the macro; the Learn LED and [MACRO] key illumination will turn off.

NOTE: Each macro can store a maximum of 64 command steps. If you exceed this number, the macro willbe stored automatically after the 64th command is added.

Example: Record a Macro to the [0] key to Turn on the T 773, Select the DVD Input, and CommencePlayback:• On the HTR 2, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns

steady green.• Press [AMP]; press [ON]; press [1] (red “DVD”); press [DVD]; press [play] (the Learn LED blinks as

each step is added).• Press [MACRO] again to exit the macro-record mode.

To clear a macro, perform the above steps without entering any functions.

EXECUTING MACROSEXECUTING MACROSEXECUTING MACROSEXECUTING MACROSEXECUTING MACROSTo execute a macro, press and release [MACRO]; its key illumination lights for 5 seconds. While it remainslit, press an HTR 2 key to which a macro has previously been stored. The corresponding macro will run; aseach step executes, its “parent” Device Selector’s key flashes lights briefly; when execution is finished, the[MACRO] key illumination goes out. Pressing any other HTR 2 key while a macro is executing will abort themacro. Remember that you must hold the HTR 2 so that its infrared emitter can activate the targetcomponents.

NOTE: When a macro executes, a 1 second delay is automatically inserted between its commands. If youneed more than a 1 second delay between particular commands—for example, to permit a component topower up completely—you can record “empty” steps into the macro by changing Device Selector “pages”without entering actual command functions.

To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 2’s [DISP] and the[0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash twice toconfirm the new setting. When set to zero, the illumination will not turn on at all.

NOTE: Key illumination is the biggest drain on the HTR-2’s batteries. A short key-illumination timeout willextend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further.

FACTORY RESETFACTORY RESETFACTORY RESETFACTORY RESETFACTORY RESETThe HTR-2 can be reset to its factory state, deleting all learned commands, copied and punched-throughkeys, macros, and other setup information, reverting all keys to their pre-programmed library commands. Toperform a factory reset simultaneously press-and-hold for 10 seconds the HTR 2’s [ON] and [RTN] keys; theLearn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the LearnLED will turn red, indicate the remote has been reset.

NOTE: You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will notreset; should this occur, repeat the full procedure.

DELETE MODEDELETE MODEDELETE MODEDELETE MODEDELETE MODEThe HTR 2 can store learned, copied, and “default library” commands on any single key. (The default librarycommands are the pre-programmed NAD codes, such as the native T 773 commands on the [AMP] “page.”)You can delete commands by layers back “down” to the default library command on any key, removinglearned commands, punched-through functions, and copied keys.

NOTE: The default library commands cannot be deleted, so you need not worry that using Delete Modemight cause irreparable changes.

To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired key’s Device Selectorkey and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wishto delete; the Learn LED flashes; the number of times indicates which type of function has become active—see the table below.

Search ModeIf none of the codes from the table, when entered, turns on the component, and if you are quite sure youhave followed the above procedure completely and carefully, you may want to try the “search” method asfollows:

Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired Device Selectorkey and the [A/V PRESET] key, until the Learn LED turns green. Now press-and-hold the HTR 2’s [ ] (or[ ]) key; the remote will step through all the available codes at a rate of approximately 1 per second. Whenthe component turns off, immediately release the cursor key; press [ENTER] to accept that code-library andexit the Library Mode. Try a few commands; should you prove to have stepped past the needed code-library,re-enter the Library Mode and use the cursor key to step back to it.

NOTE: It is possible that search mode will find code-libraries that operate, at least partially, some other-brand (non-NAD) components. You may certainly exploit such capabilities as you find them. However,since we can only ensure the completeness or accuracy of NAD code-libraries, we cannot support the HTR2’s operation with other-brand components.

Checking Code-Library NumberYou can check the current code-library on any Device Selector key as follows. Enter Library Mode bysimultaneously pressing-and-holding for 3 seconds both the desired component’s Device Selector key andthe [A/V PRESET] key, until the Learn LED turns green. Press the [DISP] key; the HTR 2 indicates the currentcode-library by flashing its [TAPE], [VCR], and [MACRO] keys. For example, to indicate code-library #501 theHTR 2 will flash [TAPE] 5 times, pause, and then flash [MACRO] once. You might wish to make a note of yourcomponents’ code-library numbers.

The ZR 2 remote control is a discrete compact remote for controlling the T 773 from various rooms other thanthe main room. The ZR 2 remote allows full separate control of the source selection irrespective to the mainroom. This means the zone input may be completely different, audio and video, from the main input andthus corresponding volume levels as well. If one wishes to enjoy the same source, as the main room the ZR2 remote has a [LOCAL] button to allow simultaneous listening, but with full separate volume levels.

The T 773’s front florescent display will show activity of the zone control so that main room occupants areaware of the zone remote activity. Furthermore if there is no main room activity, only the zone indicator willbe active in the T 773’s fluorescent display.

The T 773’s rear-panel TRIGGER output can be assigned to any of its six AV inputs: DVD, SAT, VCR, VIDEO4-6. Whenever the assigned input is selected, either manually or by recalling a Preset, the TRIGGER outputwill produce +12 V DC, which can be used to activate a connected component or system. See your NADaudio specialist for more information.
