The MTX48 is the four-zone version of the MTX series, containing two balanced microphone inputs with priority function, phantom power possibility and three-band tone control. Four stereo line-level inputs are provided to which any line-level music source such as a CD-player, tuner or MP3 player can be connected. The other two inputs of the matrix are the additional wall panel inputs for both line and microphone signals. The MTX can be controlled by means of additional control panels, its fully functional web based interface or the AUDAC Touch app. Using the freely available AUDAC Touch™ application for smart devices guarantees total system control and configuration from any device on any location and at any time. The RS232 port makes the MTX compatible with any home & industrial automation systems supporting RS232. The front panel of the MTX shows a rotary button per zone with indication LEDs for accessing controls and settings. A built-in PFL loudspeaker makes it possible to pre-listen every channel without the need for a headphone. The balanced line-level zone output connections are performed using 3-pin Euro-terminal block connectors, each of them accompanied with an RJ45 connector for connecting additional wall panels for that zone. A 24 volts’ power connection makes it possible to keep the MTX running on emergency power, even if the main power is shut down.

MTX48 Internals
The following figure shows the connectivity possibilities for a single MTX48.
Office Setup
Below we have the multi zone audio matrix being used in an office area. Two XMP44 devices are shown here, representing the possibility for adding any kind of audio source or media player to the system. Besides the available options, also computer, TV or even mobile devices can be connected as an audio source.
Computers throughout the building allow authorized personnel to access the matrix unit’s advanced options or you can control the system by using your iPad or iPhone.
Two handheld microphones can be connected for e.g. presentations but you could replace these for a table top microphone or the MPX paging microphone. All rooms inside the building have been given their own wall panel controls and extra audio inputs. This has been done in two ways, firstly by installing an MWX65 or by placing an MWX45 with line or microphone wall inputs. Don’t forget these wall panels can combine together as you can see in the meeting room and main office.
100V Installation Example
Below you can see how, when combined with a DPA154 and a TRU415 transformer, the MTX48 is perfectly suited for controlling larger store setups in 100V installations.
AUDAC Touch™
Connectivity - Inputs & Outputs
The MTX48 offers 4 output zones. Multiple input options are available. First of all, there are 2 microphone inputs with priority settings. The rear end controls offer a 3 band tone-control for each mic output, ± 15dB, as well as gain control and a phantom power button (+15V). 4 Line inputs allow you to plug in various audio sources, each with an independant gain control and clipping led on the back of the unit. Each output has its own RJ45 port, whch can handle both external audio input panels and control panels. Finally, a dedicated paging RJ45 port makes sure that all the MTX can handle all your paging needs.

Control Possibilities
What makes the MTX system superior to all other matrix systems in their range are the advanced control possibilities. The MTX can be controlled by means of additional control panels for every specific zone, with or without additional audio inputs.
It also features a fully functional web based interface whereby the audio system can be controlled and configured from any device connected in your LAN network by just using a standard web browser, while the apps for iPhone and iPad enable you to control the MTX out of your pocket.
The RS232 control port makes it possible to control it by means of any external equipment such as home & industrial automation systems supporting RS232. Finally, the front panel of the MTX shows a rotary button for every zone with indication LEDs that allow you to use all the controls and settings using an intuitive design.
Wall panels
Multiple wall panels which can be linked through are available for the MTX, ranging from simple external inputs to complex controller devices equipped with full-colour displays. Connections are made using simple and affordable CAT5/CAT6 cable to transport the audio and data for over 300 meters. All available in white (/W) or black (/B).
How to use ARJ12P with MTX series
For this 8-zone solution with MTX88, we can easily convert one of the line inputs to a Bluetooth input using a WP220 and connect it using an ARJ12P junction box. This allows the end-user to select the Bluetooth connection as an audio source for a specific zone via AUDAC Touch™, which is our simplified design, management & system control platform. Possibilities are endless; up to four WP2xx universal wall panels can be connected to a single MTX series audio matrix. Thus, each line input becomes more versatile and flexible with this approach.

Product
Answer
Any product that is updatable by the AUDAC system manager is automatically discovered and downloaded to your personal computer.
All other software versions can be found via audac.eu/software
Previous firmware versions can be found in the portal on the support tab.
Answer
Yes, it is always recommended to run the latest firmware to be compatible with AT2.
Answer
When the user password is lost, it can be changed by logging in with the administrator password. When the administrator password is lost, please contact your local distributor.
Answer
Please download the AUDAC system manger. This will scan your network and tell you the IP address of all AUDAC products within your network.
If your network is blocking global broadcasts, you can connect directly by using a cross cable. The system manager will still be able to inform you of the device IP.
Answer
AUDAC uses two methods to update their devices.
- USB
- AUDAC system manger
When unsure which method to use, please refer the product manual.
Answer
When connecting directly to the product,
- Ensure you are using a cross-link network cable
- Ensure your personal computer is within the same default AUDAC IP range 192.168.0.xxx
- Check the WIFI settings of your laptop. In many cases, the laptop will try to make a priority connection through the WIFI network, whereby it will be impossible to reach the webserver. After the WIFI connection of the laptop is disabled, it will work properly
When connecting to your product via network
- Ensure your personal computer is within the same default AUDAC IP range 192.168.0.xxx
When trying to connect with a personal media device.
- Ensure the tablet/pad is within range of both the WiFi and AUDAC IP range.
Answer
This depends of the kind of wall panel you are using.
- Wall panels with control and audio inputs : one wall panel per RJ45 input.
- Audio only wall panels : two per RJ45 input.
- Control only wall panels : these can be linked together in combination with all other AUDAC wall panels
Please refer to the product manuals for the detail connection possibilities for each matrix.
Answer
Yes, the RS232 can be controlled by any device supporting RS232. Some examples are: a computer, home and industrial automation systems like AMX and Crestron. The command set for controlling the devices over RS232 is downloadable here.
