The Adastra V-242 installation power amplifier supports two independent zones, with 100 V or low-impedance output. Its Class-D amplification section delivers 2 × 240 W RMS. The built-in audio player supports Bluetooth 5.0, DAB+/FM, and MP3 files from USB or SD.

The three mono microphone/line inputs operate in both zones and support selectable +20 V phantom power, as well as priority for channel 1. For each zone, the rotary selector switches between two unbalanced line inputs, one auxiliary line input, or the built-in player. Each zone has Bass and Treble controls and an unbalanced line output for connecting an additional amplifier.
