The Adastra RM244V integrated installation amplifier combines a mixer and a 240 W RMS amplifier, with a shared 100 V output for four zones. The four 100 V outputs have independent volume and mute controls on the front panel, while the three microphone/line inputs and AUX input support connection of audio sources.

The built-in player supports USB, SD, FM and Bluetooth 2.1. Input 1 features an override function for muting and priority bypass, while switchable +20 V phantom power is available on inputs 1–3. The two RJ45 inputs allow connection of up to two RM-4B paging stations for announcements in individual zones or all zones.
