Introduction
All-in-one wall panel
The MWX65 is an All-in-one wall panel designed for use 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
using UTP/FTP CAT5E (or better) twisted pair cabling.
The following functions of the zone can be controlled:
- Volume within a range of 0dB to -70 dB
- Input source selection
- Mute / unmute
- Bass within a range of -14dB to +14dB
- Treble within a range og -14dB to +14dB
The microphone input on the wall panel is connected using an XLR connector, while the line
inputs are implemented using RCA connectors.

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 within a range of 0dB and -∞dB.
Balanced microphone input
A microphone can be connected to this XLR input connector, which allows voice announcements
to a particular zone. For powering condenser microphones, a phantom power voltage of 12 Volts
can be software enabled.

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, audio source selection, ... can be done by rotating the dial left and
right. Actions such as selection and deselection, toggle settings, ... can be done by pressing the
knob.

Chapter 2
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.
ATTENTION
Making or changing any connections while powered-on can lead to permanent
damage of the equipment. Make sure the power is switched off while connecting
and verify correct connection method before powering on!
Connect the MWX65 wall panel to the matrix system with a twisted pair CAT5E (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 patched to the input of the zone where the local
audio input should be linked to. 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.

13
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 subsequent wall panel.
(“W002” for wall panel 2, “W003” for wall panel 3, ...)
After the desired address is selected, click the “Set address” button. A message will start blinking on
all the MWX65 wall panels connected in your system. When the function selection dial on the wall
panel is pressed, the selected address will be assigned to the corresponding wall panel.
Now the zone, which should be controlled and the selectable inputs need to be selected. The zone can
be selected by the dropdown list
This can be done in the user interface with the two dropdown lists. When the zone or input is selected,
it automatically appears inside the listbox. To remove a zone or input from the listbox, select the
desired zone or input in the listbox, and click the “Remove Zone” or “Remove Input” button.
Next to the listboxes you can find several selection & checkboxes whereby some presets / restrictions
can be made to the corresponding wall panel. After the settings are made, click the “Save to
Wallpanel” button on the bottom of the window, and your changes will be uploaded to the wall panel.
Your wallpanel is now ready for operation.

Different kinds of installation boxes are available for the MWX65, making both flush and surface
mount installation possible on different kinds of surfaces. The WB50/FG installation box allows flush
mount installation in any kind of hollow wall such as gypsum, wood or any other material with a plate
thickness between 7 mm and 25 mm. The WB50/FS installation box allows flush mount installation
through mortar in stone or concrete surfaces. For surface mount installation, wall boxes WB50/B and
WB50/W are available.
The wall panel should be fixed into the installation box by tightening the included screws.

15
Connecting
The MWX65 wall panels should be connected on the WP (wall panel) ports of the matrix system with
an UTP CAT5E (or better) twisted pair cable according to the TIA/EIA T568B standard. Depending of
the used matrix system (MTX48 or MTX88) 8 or 16 Wall Panel (WP) inputs are available, Two for each
zone. Make sure the MWX65 wall panels are connected to the right zone whereto the audio inputs
should be linked.
