The Adastra RMS605 installation power amplifier features five independent channels, each delivering 60 W at 100 V or 4 Ω. The outputs can be connected to 100 V or 4–16 Ω speakers, while each channel’s independent line input can be switched to an auxiliary input. The amplifier can be used as a supplementary amplifier or as a standalone multi-zone system.

A paging microphone input is available on all channels for voice announcements and includes VOX override and switchable +20 V phantom power. The 24 V emergency mute connections allow connection to an alarm panel. The Class D design fits into a 1U rack-mount enclosure.
