The Adastra RZ45 audio unit acts as a control hub for multi-zone installations, with 4 selectable input sources and 5 output zones. The built-in media player supports USB, Bluetooth and a 3.5 mm auxiliary input. Paging via the XLR microphone overrides the selected or local audio source in all zones.

The unit is rack-mountable and has a height of 1U. It includes a TR86 wall control unit with touch controls for source selection and output level adjustment in one zone, expandable to all 5 zones. The remote connection uses a standard network cable, while the zone outputs can be monitored via the 3.5 mm stereo headphone output.
