MTX48 - 4-zone audio matrix


The Audac MTX48 offers 4 output zones and is not only controllable using the frontend dials, but also using your web browser, iPhone or iPad.

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.

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.

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 prioritairy systems.

The front panel of the MTX shows a rotary button per zonewith 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 theMTX running on emergency power, even if the mains power is shut down.
