GENERAL

SAFETY INSTRUCTIONS

AMX-20DSP4 Automatic pre-amplifier, especially developed for applications in challenging buildings (architectural acoustics). The AMX-20DSP4 is applied in places, in which most of the other devices do not generate positive results or where a complete rack with system components would have been built, to achieve a reasonable acoustic result.

The 16 universal inputs are shiftable via DIP switches between MIC.- and LINE sensitivity.Each of the 16 universal inputs has shiftable Phantom power and a HPF filter (100 Hz).The universal inputs are equipped with shiftable automatic microphone system (DSDF), DIGITAL SIGNAL-DELAY-FIELD System. The release of all recorded microphones is done automatically and is controlled and supervised by the Processor System (DSDF).

Via the input matrix (DIP switch) all input channels 1 to 16 can be allocated to the outputs „MAINSUM-2“ and / or to the output „MAINSUM-3“.All settings of the Matrix, the DSDF System, priority resp. conference programming are described in the further chapters.

Besides this, the AMX-20DSP has the following inputs and functions: 16 inputs to XLR (MIC.-LINE), 4 LINE inputs (LINE 17-18) to Cinch (LINE 19-20) to XLR.16 x inputs equipped with automatic microphone system (DSDF), DIGITAL SIGNAL DELAY FIELD System.10 input parametric EQ.4 x 5 output parametric EQ, 4 delays, 4 volume controls and automatic feedback limiter (sum).4 DSP MASTER outputs 1 to 4, the output No. 4 can be configured as X-Over SUB output (software).2 PresetsDigital input NOISE-GATE and signal limiter (software)Two input groups IN-1 (inputs 1-20 with ROUTING to outputs 1-3) and IN-2 (inputs 17-20 with ROUTING to output 4, (SWITCHING MATRIX)Freely programmable calendar function (automatic switchover of the presets 1-2)INFO OUT (PRESETS-2) isolated relais. For instance, auxiliary speaker lines for presets 2 can be connected.PRE-MASTER & EQ output (signal output before MASTER and audio DSP).

All these setting possibilities provide an even more precise room equalization and best adaptions to the room acoustics resp. architectural acoustics.

Power amplifiers of the serie MW-200B, MW-400B and MW-600B are available as power final stages.

Do not cover the rear ventilation slots! Above, behind and under the device must be an adequate space for air circulation.

DEVICE HARDWARE CONFIGURATION (COMPRESSOR-EXPANDER)

Each input channel 1 to 16 of the mixer AMX-20DSP4 can optionally be equipped with a compressor expander sys-tem. The control possibilities for the compressor and the expander are located at the upper cover plate of the AMX-20DSP4 mixer. By turning of the corresponding trimmer, the settings for compressor resp. expander can be changed.

An audio compressor belongs characteristically to the control amplifiers. It accesses to the dynamics of an audio signal and reduces them. The dynamic describes the level difference between the loudest and the lowest points of an audio signal.

An audio expander accesses to the dynamics of an audio signal and increases it, in opposition to the audio compressor. With the input channel switch ON/OFF, the compressor expander switching can be activated or changed to bypass, that means switched off.

PROGRAMMING WITH SOFTWARE „MWL-EASY MANAGER 2.0“ FOR DSP4-SYSTEMS

All functions and settings are practicable either directly in the mixer by the SETTING/ENTER-buttons, or can be programmed via a connection of the AMX-20DSP4 system with a PC.

Installation and operating instructions:

Before you can use the „MWL Easy-Manager 2.0“ Software, at first the NET Framework 3.5 for Windows NT, XP and 98 has to be installed (precondition is the installed Microsoft SERVICE PACK 1).IMPORTANT: higher versions of NET Framework from 4.5 are not supported anymore by Windows NT, XP and 98.

The NET Framework 3.5 is located on the installation-CD or can be installed from the Microsoft-Website. LINK: http://www.microsoft.com/de-de/download/details.aspx?id=17851

Afterwards the program MWL Easy-Manager 2.0 resp. the file MWL EasyMgr2.0 Install/Setup.exe can be installed at the PC via a „double click“. After the installation the program is started automatically.

After the USB-connection between AMX-20DSP4 system and the PC, the computer notifies a new device in the system and the program automatically obtains a new COM-Port (this may last for a few seconds).

The programm scans the available COM-ports and indicates the connected devices. Please mark the favoured COM-port and press the CONNECT-button. The connection between PC and system is generated.

To be able to make a connection with the amplifier, option „CONNECT“ must be selected in the area „communication“.

SOFTWARE RANGE „PRESET SELECT“

Presets selection, all software settings always refer to the selected presets number of the range „PRESET-SELECT“. Two presets, PRESET 1 or PRESET 2, can be selected.

SOFTWARE RANGE „SIGNAL DISPLAY“Signal beams of the particular output channels (1 to 4).

When the audio signal is connected, the output signal level is displayed digitally by signal beams in the range from - to +3 dB.

SOFTWARE RANGE „NOISE GATE“„Threshold“The Noise Gate cuts signals under a particular, definable le-vel (-90 dB to -24 dB). But signals over this level are passed unprocessed. A typical use is noise suppression with low level. Here the adju-stable limit level (threshold setting) is regulated directly above the noise level. Potentially existing noise is suppressed here, as soon as the master volume of the input signal underruns the threshold setting.

If the master volume is over the TH-setting, indeed also noises are passed, but covered by stronger wanted signals. Useful information:

Please select the favoured „PRESET“. Two PRESET configurations can be carried out for all programming processes.


15.


SOFTWARE PROGRAMMING „LIMITER 1“„Threshold“- „ATTACK TIME“

In the menu LIMITER 1 via threshold setting (-30 dB to +6 dB) you determine the crossover level, over which the effect of the limiter 1 starts.

By level raising the limiter is started later.

In the menu LIMITER 1 via ATTACK TIME you determi-ne the reaction rate of the internal shift to the input signal.

SLOW - longer ATTACK-timeMIDDLE - middle ATTACK-timeFAST - fast ATTACK-time

The longer the ATTACK-time (SLOW-position) is selected, the later the limiter effect starts.

With longer ATTACK-times the limiter more effects the average signal level and no more the fast and high peak levels.This causes a softer limiter effect and retains the signal dynamics widely, but cannot avoid temporary overrides due to fast signal peaks.

Useful information:

Longer attack times in case of percussive signals let the dynamic tone level „PICK“ pass, without controlling the level down.

A „KICK DRUM“ also keeps its „PUNCH“ in case of longer attack times.Also for RECORDING resp. final mixing a little bit longer attack times are preferred.

To protect speakers from too high peak levels in PA-applications, however, short attack times are advisab-le (FAST-setting).

IMPORTANTThe LIMITER 2 can analogue be programmed to LIMIT-ER 1 (LIMITER 2 for input group IN2, inputs 8 and 9).

SOFTWARE PROGRAMMING „INPUT EQUALIZER“

Via mouse click to the INPUT EQUALIZER window you get into the submenu „INPUT PEQ“. There all audio settings for the parametric EQ of the input range can be carried out.All changes are displayed graphically as trajectory in the monitor window.

Useful information:

A parametric equalizer PEAKING EQ allows the raise or driving of freely selectable frequencies with the possibility to determine the extent of effects (Q-factor) of the EQ by yourself. Thus it differs from LoSh6/12 and HiSh6/12 filter, which can control a specific frequeny range (for steady Q-factor).Please consider the display.

SOFTWARE PROGRAMMING „CROSSOVER-MATRIX“

For the first configuration all IN 1 inputs (1 to 20) are allocated to the outputs 1 to 4. All outputs are supplied with an audio signal from the groups IN 1 and IN 2.

For the second configuration all IN 2 inputs (17 to 20 LINE/CD) are allocated to the output 4.Output 4 is not supplied with the audio signal from the group IN 1 (inputs 1-16).

IMPORTANT:All channels from the „IN-1“ input group can be allocated individually to the output 4 (OUTPUT 4A / 4B) by PROGRAMMER 2A (channels 1 - 8) and PROGRAMMER 2B (channels 9 - 16).

Useful information:

This adjustment is preferred, when for instance an active SUBWOOFER or a PA-amplifier system for music- resp. acoustic background is connected to the output No. 4.

Thus the microphone signals are only relayed to the outputs 1A/B to 3A/B, MAINSUM-2 /3 and not to the SUBWOOFER resp. the PA-speakers.

By this setting the STIPA value is improved considerably.

Important information:

Please selected the favoured „PRESET“. Two PRESET configurations can be carried out for all programming processes.

Useful information:


A parametric equalizer PEAKING EQ allows the raising or driving of freely selectable frequencies with the possibility to determine the width of effects (Q-factor) of the EQ by yourself.

SOFTWARE PROGRAMMING „DELAYS“ signal delay

Via mouse click onto the DELAYS-window you get into the submenu „OUTPUT DELAYS“ (OUTPUT 1A/1B, 2A/2B, 3A/3B, 4A/4B).

One DELAY is available for each output.Information in „ms“ (time delay) can be set.

1. DELAY-OUT-1, delay setting for output 1A/1B.2. DELAY-OUT-2, delay setting for output 2 A/2B.3. DELAY-OUT-3, delay setting for output 3A/3B.4. DELAY-OUT-4, delay setting for output 4A/4B.

TIP: A minimum signal delay of f.i. 2 ms has a positive effect to feedback deficit.

A signal delay allows a correct sound by delaying the acoustic signals in a way, that there are no echo disturbances even in case of speakers or amplification systems which are arrayed far from each other.

Our digital audio signal delay is constructed in studio quality switchgear and uses widely the computer generated processing of the digitized signal.

It offers an automatable control of the delay times via very small quantization levels of the signal delay.

ROOM EQUALIZATION

Thank you very much for deciding for the Automatic AUDIO-MIXER AMX-20DSP4 from Phoenix Professional Audio. To be able to use the Mixer AMX-20DSP4 and to use all technical possibilities which offers this model, you must carry out a room adjustment resp. room equalization after the installation. To realize a room measurement you need a gauge. Minimum for this purpose is the NiniLink (Acoustilyzer) from Neutrik or a professional measuring software like f.i. MLSSA.

For a practical measurement the measuring microphone has to be positioned exactly at the place, where later the audience will be located (f.i. for church sound in the middle of the church). By recording of „PINK NOISE“ to the Power Voice amplifier you measure the amplitude frequency response with the measuring microphone.

ist Wert

sol Wert

If the appraised frequency response does not have the aspired run, a correction by raising and driving of the frequency spectrum is carried out with room adaption filters (EQ) in defined areas.

Repeat the measuring- and adjustment procedure, until a linearity is generated (see drawing No. 2).

In big halls or in case of bigger distance from the signal sources (f.i. speakers) a drop in treble occurs. For reverberant rooms it is senseful to concentrate additionally on the equalization of low frequencies up to 100 - 800 Hz. In this frequency range there is the highest reverb effect.It showed up that a skilled approach to the equalization is advisable. Here always the capacity of the speaker and the amplifier should be considered.

ROOM EQUALIZATION

Equalization for feedback suppression

The positive feedback between microphone and speaker produces the so-called acoustic feedback, which always starts at the frequency which shows the strongest maximum at the transmission curve. This can be damped by the automatic feedback limiter which is integrated in the MIXER like follows:

At first you should reduce the parasitic frequency narrowband (OCT.) with the parametric EQ for a favoured value (dB). Then produce a feedback by raising the microphone sensitivity. Measure the occuring frequency and correct it with the parametric EQ.

The green curve shows the recommended playback curve for voice amplifier systems.

The MIXER AMX-20DSP4 has a 10-element parametric input-EQ and per output 5-element parametric EQ. Thereby even acoustic difficult rooms can be equalized very well and the microphone sensitivity can be raised without interfere feedback.

PROGRAMMING NOISE GATE „Threshold“

The Noise Gate cuts signals under a determined, definable (-90 dB to -24 dB) level. Signals which are above this level, however, are let pass unprocessed. A typical use is the suppression of noises with low level. Thereby the adjustable threshold (threshold setting) is adjusted directly above the noise level. Possible existing noise is thereby suppressed as soon as the master volume of the input signal underruns the threshold setting.

If the master volume is above the TH-setting, indeed also noises are let pass, but they are covered by stronger wavelets.

DISPLAY „LIMITER 1“

A white panel in the display always shows the current cursor position (program range).

PROGRAMMING LIMITER 1 „Threshold“ - „ATTACK TIME“

In the menu LIMITER 1, by threshold setting (-30 dB to +6 dB) you determine the changeover level, above which the effect of the limiter 1 starts.

By level increase you let start the limiter later.

In the menu LIMITER 1 by ATTACK TIME you deter-mine the response time of the internal shift to the input signal.

SLOW - longer ATTACK timeMIDDLE - middle ATTACK timeFAST - fast ATTACK time

The longer the ATTACK time (SLOW-position) is selec-ted, the later the limiter effect starts.

With longer ATTACK-times the limiter more effects the average signal level and no more the fast and high peak levels.This causes a softer limiter effect and retains the signal dynamics widely, but cannot avoid temporary overri-des due to fast signal peaks.

Useful information:

Longer attack times at percussive signals let the dynamic tone level „PICK“ pass, without turning the level down.A „KICK DRUM“ also keeps its „PUNCH“ at longer attack times.Also for RECORDING resp. final mixing a little bit longer attack times will be preferred.

To protect speakers from too high peak levels in PA-applications, however, short attack-times are recom-mendable (FAST-setting).

IMPORTANT

LIMITER 2 can analogue be programmed like LIMITER 1 (LIMITER 2 for input group IN2, inputs 17 and 20 and DIP-2A/2B settings).
