Introduction
All-In-One Wall Panel
The MWX65 is an All-in-one wall panel designed to work in combination with AUDAC MTX series
matrix systems. This wall panel has a graphic display and can control the routing, volume, bass, treble
and mute for one zone. Besides those control functions, it also provides the possibility to connect a
microphone and a stereo line input source. The MWX65 wall panel should be connected with UTP/
FTP Cat5 (or better) cable.
The following functions of the zone can be controlled:
- Volume within a range of 0dB to -70 dB
- All input sources can be selected
- Mute can be activated
- Bass within a range from -14dB to +14dB
- Treble within a range from -14dB to +14dB
The microphone input on the wall panel is connected with a female XLR connector, while the line
inputs are performed using RCA connectors.

Overview front panel
The front panel of the MWX65 wall panel contains a 2.5” Graphic color LCD display with two additional
audio inputs. The unbalanced line input is connected with RCA connectors while an XLR connector
is used for connecting balanced microphones. Each input is accomodated with a push-lock gain
control potentiometer and a Clip indicator LED. A big rotatable function selection push dial is provided
below the LCD display.

Front panel description
Unbalanced line input
An unbalanced stereo audio source can be connected to these RCA connectors, creating an
additional local input.
Push-Lock gain control potentiometer with clipping LED
The sensitivity for the line and microphone inputs can be adjusted with these potentiometers.
Through the push-lock mechanism, they can be opened and hidden again by pressing them.
Above every potentiometer is a clipping indicator LED provided which illuminates when clipping
of the input signal occurs. When this LED is lit, the signal is distorted and the level should be
reduced by turning back the potentiometer. The sensitivity for the line and microphone input can
be adjusted between the ranges of 0dB and -∞dB.
Balanced microphone input
A balanced microphone can be connected to this XLR input connector, which allows to announce
messages from a specific zone. For powering condenser microphones, there’s the possibility to
provide +12V phantom power to this microphone input. (Software selectable)

2.5” Graphic color LCD display
This graphical color LCD displays gives a clear overview of all the functions and settings of the
wall panel.
Rotatable function selection dial
The big rotatable dial enables you to control all functions and settings of the wall panel by just
three simple actions: Rotate left, Rotate right and Push. Actions such as browsing between the
zones, increasing the volume, selection of the audio source, ... can be done by rotating the dial
left and right. Actions such as confirming, cancelling, toggling between settings, proceeding and
returning to the previous window can be done by pushing the button.

Overview rear panel
The rear panel of the MWX65 contains an 8 pin connector for connecting the wall panel to the matrix
system and a jumper for terminating the RS485 databus. A detailed description of how the MWX65
should be connected, can be found in the Chapter 3 of this user manual. The jumper for terminating
the databus should always be placed when only one wall panel is connected to the databus, and is
always provided and placed by delivery.

Quick start guide
This chapter guides you through the setup process for a basic project where a MWX65 wall panel
should be connected to an MTX series audio matrix. Make sure the audio matrix is installed correctly
and is powered off when connecting the MWX65 wall panel.
Connect the MWX65 wall panel to the Matrix system with a twisted pair CAT5 (or better) cabling with
a maximum cable length of 300 meters. Make sure the MWX65 is connected to one of the wall panel
inputs on the rear side of the MTX. It should be connected to the input of the zone where the local
audio input should be available. Go to the setup menu in the web based interface of the MTX and go to
System configuration. Click on MWX65 for making the settings.
An unique address should be selected for every connected wall panel. The address for a wall panel
always starts with the letter “W”. When only one wall panel is connected, the most logical way is to
start with address “W001”, and increase the address number for every additional wall panel. (“W002”
for wall panel 2, “W003” for wall panel 3, ...)
