The system includes a handheld UHF microphone with an inbuilt receiver and 2 switchable wired mic/line inputs are provided on combo XLR/jack sockets. Each mic input has switchable +48V phantom power and priority override, whch mutes the Aux inputs during voice operation. An internal media player enables playback of audio tracks from USB/SD player, DAB+/FM tuner or Bluetooth pairing.

For emergency control, there are 24V terminals on the bottom for patching into an alarm panel to mute all except the Mic 1 input.
