MTX88

Name: MTX88 - 8-zone audio matrix
Brand: AUDAC

The MTX88 is the eight-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 where to 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 iPhone/ iPad Remote app. 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.

Example setups

The following figure shows the connectivity possibilities for a single MTX88.

The following figure demonstrates a typical setup based around an MTX88 audio matrix.

Below you can see how, when combined with a DPA616 and a TRU812 transformer, the MTX88 is perfectly suited for controlling larger store setups in 100V installations.

Functionality

The MTX88 offers 8 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.

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.

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).
