Adastra 5-Zone Remote Audio Matrix with Bluetooth (RZ45)

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.

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)

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.

3. We always refund the payment according to how the original purchase was made and aim to do so within 72hrs of the return being received by us.

4. Returned goods are liable for a restocking fee of 15% towards handling and repackaging if the order is not returned in its original, unopened packaging. This charge will be subject to our inspection of the returned goods.
