The Adastra V-122 installation mixer amplifier distributes sound across two independent zones, with 100 V or low-impedance outputs. Its built-in player supports DAB+/FM, USB, SD and Bluetooth 5.0 for playing music or spoken announcements. It features Class D amplification and delivers 2 x 120 W RMS output power.

Three balanced microphone/line inputs are available in both zones. Input 1 has selectable priority, and the XLR inputs support switchable +20 V phantom power. Each zone features a selector for two line inputs, an auxiliary input and the internal player, as well as bass and treble controls. Line outputs allow additional amplifiers to be connected to expand the system.
