The Adastra RM60D installation amplifier combines a 5-channel mixer and a 60 W amplifier for sound systems with 100 V line speakers or conventional 4–16 Ω speakers. The built-in player supports DAB+/FM, Bluetooth 5.0 and files from USB or SD. VOX mode automatically lowers the music volume when a signal is detected at microphone input 1, while the 24 V contacts can mute all inputs except this one.

The speaker outputs include four switchable 100 V zones and one unswitched output for priority announcement speakers. The first microphone’s XLR input has switchable +20 V phantom power, while the controls adjust microphone and line levels, bass, treble and master volume. The amplifier can be mounted in a 19-inch rack and operates on 230 V AC or 24 V DC power.
