Central unit MTA816, for controlling and managing the multiroom audio broadcasting system.
The unit is equipped with 9 audio inputs (8 centralized + 1 local audio input for each zone).
It can manage 6 zones which can be extended up to 48 by adding up to 7 expansion units MTAE816.

The main unit is equipped with a powerful microprocessor which enables the digital control of all the zone parameters both centrally by means of the front panel and through remoted control units.

Functions supported:

  • zone and source on/off
  • source selection
  • volume control
  • bass and treble, balance
  • mute
  • loudness
  • sleep
  • function control for the audio sources equipped with STIF devices

The control unit has further features that makes it extremely flexible:

  • e.g. room name customization
  • stereo or mono output configuration
  • programmable weekly alarms
  • paging management from paging station
  • up to 14 programmable priority levels relating to the inputs for managing music
  • microphones (general paging and alarm messages)
  • pre-recorded messages (for providing information or alarms) with DAP90 external player.

The main unit is equipped with Ethernet and RS232 interfaces and can be controlled by PC using suitable software, from Smartphone or Tablet (app Live MT),or interfaced with any advanced home automation system; it is ideal for scenarios and events that are started via software or simply by programmable triggers.
