The Adastra MM240 mixer-amplifier combines a PA amplifier with a built-in media player, FM tuner and Bluetooth. It delivers 2 × 120 W RMS into 4 Ω and features three mono microphone or line inputs via XLR, plus two stereo RCA auxiliary inputs. Channel 1 has adjustable priority, while inputs 1–3 support switchable +20 V phantom power for condenser microphones or D.I. boxes.

The media player plays audio from USB or Bluetooth and includes an FM tuner and a 3.5 mm Aux input. The L/R speaker outputs use Euroblock connectors, and there are stereo XLR line outputs and an RCA recording output. The 24 V emergency mute contacts disable all channels except channel 1. The amplifier fits a 1U rack and is intended for background music and announcements, as well as installations with additional amplifiers.
