MTX88 - 8-zone audio matrix

MTX88 - 8-zone audio matrix


The MTX series are AUDAC’s series of very cost-efficient audio matrix systems for a wide variety of multi-zone audio applications, offering two different models with the same features and possibilities, but with different zone capacities.

The MTX88 is the eight zone version of the MTX series, equipped with two balanced microphone inputswith priority function, phantom power possibility, and three-band tone control.

There are also four stereo line-level inputs to which any line-level music source such as a CD player, Tuner or MP3 player, etc can be connected.

The other two inputs of the matrix are the additional wall panel inputs for both line and microphone signals.

What makes the MTX system superior to allother 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.

RS232 makes it possible to control it through home & industrial automation systems, while a contact input mutes the overall system in case of contact output from emergency or other priority systems.

The front panel of the MTX shows a ScrollPush™ control button with an indicator LED for every zone which controls all the zone’s 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 outputs comprise 3-pin Euro terminal block connectors, each of them accompanied with an RJ45 connector for connecting additionalwall panels for that zone.

A 24 volts power connection makes it possible to keep the MTX running on emergency power, even ifthe mains power is shut down.
