The Adastra RZ45 5-Zone Audio Matrix System is designed to offer a flexible and expandable solution for multi-zone commercial sound systems. 

This remote audio system provides complete control of up to 5 areas/zones all from a touch operated remote wall plate (one wall plate supplied). The touch operated remote wall plates enable you to control the volume, audio source & microphone paging from within the area/zone you are in. 


A typical setup - Office Building

  • Zone 1 - Main office
  • Zone 2 - Reception
  • Zone 3 - Meeting room
  • Zone 4 - Kitchen
  • Zone 5 - Staffroom


The Adastra Matrix System will allow you to have different audio sources playing in each area. For example, you could have the FM radio playing in the reception and main office areas, and then either a Bluetooth device or TV playing in the staffroom. The volume can also be controlled for each area. 

The Adastra RZ45 Audio Matrix System can be installed into a 19" Rack cabinet or case. It takes up 1U of rack space.


Remote Wall Plates

Only one TR86 is supplied with the RZ45 system but up to 5 may be connected to activate as many zones as are required.

Each TR86 remote control can select an audio source from 1, 2, 3 or 4/USB. Audio sources 1, 2 and 3 are line inputs which can be connected to the rear panel of the RZ45 via L+R RCA sockets. You can connect a range of devices to these inputs such as smartphones, tablets, laptops, TVs or external CD/media players.
The output level for each of these can be trimmed using rotary level controls to avoid overloading the zone output.

Audio source 4 is labelled as 4/USB since it is fed from the internal media player, which can playback files from USB or Bluetooth.

The TR86 is touch-operated with a toughened glass surface and is designed to fit into a single gang 86 x 86mm back box (supplied)

Additional TR86 remote units are available separately (953.050).
The TR86 Remote Wall Plates are connected via a standard network cable with a RJ45 connection. This will deliver power to the TR86 for up to 100m.
For longer cable runs up to 1km, the TR86 will require separate local 24Vdc power supplied to the screw contacts at the rear. 


CS-5 Call Station (optional)

The Adastra CS-5 Call Station can be connected to the RZ45 Audio Matrix via standard network cable with RJ45 connections. 

Like the TR86 Wall Plates, the CS-5 Call Station requires a separate 24Vdc power supply if the network cable run is longer than 100m. This will enable the CS-5 to operate up to 1km away from the matrix system. 

The CS-5 Call Station is perfect for making an announcement or emergency message to a certain area or throughout the whole building. 
When a signal is picked up from the microphone all other inputs will be muted to ensure the message can be heard clearly. Once the mic is deactivated all zones will be rest back to their previous settings. 
The Adastra CS-5 Call Station can be purchased separately -

Emergency Mute
You can connect a 24Vdc trigger from an emergency alarm panel (e.g. fire alarm) to the 24V mute contacts on the rear panel. This will mute all except the paging microphone and the EMG Audio input when the alarm is activated and sends 24V to the contacts.
The EMG Audio input is an unbalanced line input via screw terminals, which is enabled to all zones during emergency triggering. A pre-recorded evacuation message or siren recording may be continually played into this input but will not be heard until triggered
