B. Objects have fallen, or liquid hasbeen spilled into the
appliance; or
C. The appliance has been exposedto rain; or
D.The appliance does not appear tooperate normally; or
E. The appliance has been droppedor the enclosure is
damaged.
17. Servicing - The user should notattempt to service the
appliancebeyond that described in the operat-ing instructions. All
other servicingshould be referred to qualified
servicepersonnel.
18. Avoid using a telephone (other thancordless type) during an
electricalstorm. There may be a remote risk ofelectric shock from
lightning.
19. Do not use the telephone to report agas leak near the
leak.
Precautions1. Do Not Touch The DPA-1.2 With Wet
Hands. Do not handle the DPA-1.2 orpower cord when your hands
are wetor damp. If water or any other liquidenters the DPA-1.2
cabinet, take theDPA-1.2 to qualified service personalfor
inspection.
2. Location of the DPA-1.2 - Do notexpose the DPA-1.2 to direct
sun lightor heating units as the DPA-1.2 inter-nal components
temperature may riseand shorten the life of the compo-nents. Avoid
damp and dusty places.
3. Care – From time to time you shouldwipe off the front and
side panels andthe cabinet with a soft cloth. Do notuse rough
material, thinners, alcoholor other chemical solvents or
clothssince this may damage the finish orremove the panel
lettering.

2. INTRODUCTION
Congratulations on your recent purchase of the Russound
DPA-1.2two-channel amplifier. The DPA-1.2 is a high-current,
high-qualityamplifier, which includes automatic A/B switching. The
DPA-1.2two-channel amplifier will amplify a source at the sensing
lineinput or the sensing speaker level input. Switching between
adefault audio source and a local source, the DPA-1.2 is ideally
suit-ed for those applications that require automatic switching
andamplification. The DPA-1.2 power output per channel is 35
wattsper channel into 8-Ohms, and 45 watts into 6-Ohms. Bridged
out-put provides 70 watts of power into 8-Ohms. Each amplifier
outputchannel incorporates thermal, and short circuit protection
andRussound’s unique Dynamic Clipping Sensor that allows for
betterheadroom and volume without clipping or distortion.
The Russound DPA-1.2 amplifier is built with pride.
Fidelity,Reliability and Quality are the primary objective.
Russound prod-ucts are guaranteed to provide years of
enjoyment.
3. POSSIBLE SYSTEM CONFIGURATIONS
The DPA-1.2 can be used as a single-source two-channel
zoneamplifier, or as a local-source amplifier that automatically
switchesbetween a default source (such as a whole-house audio
distributionsystem) and a local source (such as a television
set).

4. FRONT PANELPower Switch: Turns on the main power for the
ampli-fier. When the power is on, the LED will be illuminated.
5. BACK PANEL CONNECTIONSLine Input: This line input is a
sensinginput that will activate the DPA-1.2when an audio signal is
present. Whenthere is no audio, the amplifier will gointo standby
or default back to thewhole-house amplified signal if
playing.Speaker Level Input: The speaker level input is asensing
input that will automatically switch the DPA-1.2 from the default
input to the speaker level input.This input would be used in place
of the line audioinput. An amplified signal from a smaller
amplifier ortelevision can be amplified by the DPA-1.2 for
acleaner, more dynamic sound.Gain Controls: Left and Right gain
con-trols independently adjust the soundlevel for each channel.
When in thebridge mode, only the right controlis used. Stereo /
Mono Switch: The Stereo /Mono switch selects stereo or mono for the
speakeroutputs. In the Mono position, each Left and Rightoutput is
Mono. The Mono portion is also used forbridged operation. Video
Input: The Video Input is a sensing input thatwill activate the
DPA-1.2 when a videosignal is present. When there is novideo, the
amplifier will go into standbyor default back to the
whole-houseamplified signal if playing.

Speaker Outputs: The A and B speaker outputs are in parallel to
theamplifier output. When connected to the A or B output, either
6-ohm or 8-Ohm speakers could be used. When using both A and
Bspeaker outputs, only speakers with impedance higher than 8Ohms
can be connected. For Bridge amplifier operation, connectthe + of
the speaker to the R+ and - of the speaker to the L+ of
theamplifier.

12-Volt Trigger In and Out: The Triggeroutput is 12 volts at a
maximum of100mA. This can be used to drive arelay- operated AC
outlet or other 12-volttriggered devices. The 12-volt triggerinput
is used to activate the DPA-1.2 independently from the autoturn on
sensing circuit, in which case the delay, video and audiosensing
are bypassed. Delay Time: The delay timecan be adjusted from
about0.3 minutes to 8 minutes. The DPA-1.2 amplifier
willautomatically switch to the default input signal after thedelay
setting. (When set between 4 and 5, defeats delaysetting). When the
audio or video source is no longerplaying, the DPA-1.2 will switch
back to the default input after theset delay time. Power: The
DPA-1.2 is set at the factoryfor operation of either 120 VAC 60Hz
or230 VAC 50Hz. Please reference thevoltage rating on the back
panel.Includes detachable 2 terminal power cord.
