The Adastra MM3260 installation amplifier combines a 1U rack-mount mixer with a media player and Bluetooth receiver. It delivers 60 W of power on a 100 V line and features three mono microphone/line inputs, switchable between the two modes. Channel 1 has adjustable priority, and the 24 V emergency contacts mute all channels except this one.

The media player supports USB, FM radio and Bluetooth, while the 3.5 mm Aux input allows you to connect an external audio source. The main speaker outputs connect via Euroblock screw terminals, and the line outputs use XLR connectors. It also includes an RCA recording output and controls for the channels, bass, treble and master level.
