Introduction
T
This section describes briefly the functionality of the M1amplifier.
he M1 Multimedia Amplifier is developed as a “all in one”, flexible solution for multipurpose use.
During the development of the M1, the AUDAC-engineers wanted to achieve four goals:
- Delivering a flexible audio solution for multi purposes.
- Easy to use
- Excellent sound quality
- An advanced digital control interface
Where other multi-zone amplifiers aren’t ‘all in one’ devices, the M1 is a truly polyvalent solution.
It has the flexibility of an advanced multi-zone mixer, combined with several digital options. By
simply surfing to the webpage, you can get full control of the M1 basic functions. The M1 can be
directly plugged into a basic Ethernet LAN network. No extra control software is needed, just a
computer (pda, pocket pc, …) and a web browser with the Macromedia Flash Player 6.0 (or
higher) plug-in installed, will do the job.
The M1 can be used in commercial applications such as restaurants, clubs, bars, theatres, hotels,
conference facilities, houses of worship, professional offices, …
As a simple example, when installed in a restaurant, the M1 can provide popular music in the bar,
cocktail music in the lounge, jazz in the waiting area, and classical music in the dining room.
Six microphones can be plugged in (XLR) with individual zone paging or mixing zone paging.
Each room can have a digital wall mounted control panel for selecting a music source, and setting
the volume.
There are two versions of the M1
- M1: with 2 x stereo 150W /4Ohm Amplifier (Only for Zone 1 and Zone 2 !)
- M1-Light: Without built in Amplifiers

Getting Started
When turning on the power, the M1 start-up procedure will take place. This will take about 30sec..
Selected zones will light up green. One of the 4 line sources on ch 7-10 will light up.
You can route an Input to a specific Zone Output simply by pressing the routing button once. By
pressing the button a second time, the routing will be cleared.
Balance and volume from the Input Channels can be changed on the front panel. Volume, Treble
and Bass level from the Output Zones can also be changed on the front panel. When an input
signal is clipping, the according clipping led on the front panel will light up red. Stereo VU-bars
indicate the signal level on the Output Zones and on channel 7-10 (Pre-fader).
On the rear panel ‘fixed’ settings can be made. The source for the input channels can be set to
either Microphone (XLR) or Line Level (Cinch). Individual phantom power switches are supplied
for each input channel. Channel 1-6 has a 3 band tone control and an input gain adjustment.
Channel 7-10 has a 2 band tone Control and an input gain adjustment.
The output section on the rear panel of the M1 Light has 4 balanced stereo output zones (XLR).
The M1 has also two 2 stereo output amplifiers (2x 150W /4Ohms stereo) for Zone outputs 1 and
2 available through Speakon connectors.
The M1 can be controlled with Wall Mounted Control Panels (RS-485). Each Wall Mounted
Control Panel has to be set to control the right room. This can be done by setting “jumpers” on
the inside of the Wall Mounted Control Panel.
Input Channel 1 and 2 can have the “Priority” setting. This means, when there is a signal on Ch1
or Ch2, all other input channels of the same output zones will be muted. The priority can be
switched on or off with DIP switches on the rear panel.
The amplified outputs for Zone 1 and 2 can be set in bridged mode by setting a jumper in the
inside of the M1. This has to be done by qualified people. (Not available on the M1 Light)

Special functions
SAVE SETTINGS
Routing settings can be saved by pressing together the ‘ch7’ and ‘ch8’ buttons on the front panel
of the M1. Hold down the 2 buttons for a few seconds.
RECALL SETTINGS
Recalling the saved routing settings can be done by pressing together the ‘ch9’ and ‘ch10’ buttons
on the M1 front panel. Hold down the 2 buttons for a few seconds.
ENABLE OR DISABLE THE KEYBOARD
The routing buttons (Z1 to Z4) of the input channels on the front panel of the M1 can be disabled
by pressing together the ‘ch7’ and ‘ch10’ buttons. Hold down the two buttons for at least 10
seconds !!
To enable the routing buttons on the front panel of the M1, press down the ‘ch7’ and the ‘ch10’
buttons simultaneously for at least 10 seconds.
MIXED MODE
Standard the M1 starts up in non-mixed mode. This means an output zone can only be assigned to
one input channel. The M1 can be set in mixed mode by pressing together the ‘ch8’ and ‘ch9’
buttons. Hold down the ‘ch8’ an ‘ch9’ buttons for at least 10 seconds !! It is now possible to
assign more then one input channel to the same output zone.
To disable the mixed mode setting, press down the ‘ch8’ and the ‘ch9’ buttons simultaneously
for at least 10 seconds.
REMEMBER
If you do not save the settings, the next time the M1 starts up it will recall the standard or
previously saved settings !!!!!

Bridge Mode
The M1 Multimedia amplifier can also be set in bridged mode (300W / 8ohm) by setting some
jumpers on the inside of the M1. This has to be done by qualified people !!
In the following paragraphs the proper wiring for a bridged M1 stereo setup is explained.
Connect the left output channel of the audio source to the left channel of an input channel of the
M1. Connect the right channel of the audio source to the left channel of another input channel of
the M1.
The speakers need to be connected between the “ 1+ ” and “ 2+ ” on the speakon connectors of
the left channels of the amplified zone outputs. Only the left channels of the amplified zone
outputs are supported in bridge mode. Do not connect anything to the right channels of the
amplified zone outputs. The line levels are also available on the left channels of the XLR
connectors of the zone 1 and zone 2 outputs.
Route the input channels to the desired zone outputs. In case of the example above, we have to
route input channel 6 to zone output 1 and input channel 5 to zone output 2.

Remote Control Interface
Chapter
5
To use the remote control interface, the M1 has to be plugged in to an Ethernet LAN network
with a standard (straight) network cable.
Make sure the M1 default network address (192.168.0.180) is within range of the connected
Ethernet LAN network ! If the M1 default network address is not within range of your LAN
network, contact your network specialist. The default network address can be changed with the
Standard Web Based User Interface but therefore a network connection has to be made first.
A pc (or pda, pocket pc, …) with a web browser and the Macromedia Flash 6.0 plug-in (or higher)
installed, is necessary to use the web based user interfaces. The pc needs to be connected within
the same Ethernet LAN network.
The default URL for the Standard Web Based User Interface is: http://192.168.0.180

Wall Mounted Control Panels (Optional)
The M1 Multimedia amplifier can be equipped with wall mounted control panels on each zone
output. A zone output can be controlled by more then one wall mounted control panel. The
maximum number of wall mounted control panels connected to the M1 multimedia amplifier is 4.
These wall mounted control panels are controlled by an RS485 data bus and must be connected
with the M1 with “twisted pair” or “CAT5” cable.
Following settings can be changed:
- Volume of the zone output which the panel is configured for (e.g. Zone 1)
- Input source selection. (e.g. CD player, Tuner, Microphone…)
The wall mounted control panel can be configured to control the settings of a zone output (e.g.
Living room, Board room …). This is done by jumper settings on the inside of the wall mounted
control panel.
If the wall mounted control panel is connected to the M1, and the M1 is turned on, the digit on
the wall mounted control panel will show a zero for a couple of seconds, for the next couple of
seconds it will show the zone output for which the wall mounted control panel is configured and
last it will keep displaying the selected input source.
When changing the volume of the zone output, the digit on the wall mounted control panel will
show the zone outputs volume. The volume will be changed in smaller steps then the digit can
show. If one of the volume control buttons is held down, the volume will keep increasing or
decreasing. After the change has been made, the digit will show again the selected input source.
