The Adastra RM480D PA integrated amplifier is a 5-channel mixer for commercial sound installations, delivering 480 W of power. It powers 100 V line speakers or conventional 4–16 Ohm impedance speakers. The four switchable 100 V outputs and the separate non-switchable output are connected via screw terminals.

The built-in player supports USB and SD, and audio can also be played via Bluetooth. The voiceover function automatically lowers the music volume when a signal is detected at microphone input 1. The 24 V emergency contacts can mute all inputs except microphone input 1.
