3 Microphone Inputs:
The 1st microphone input is the ‘priority’ channel and its signal is always internally routed to:
Telephone channels for ‘private’ communications with the callers, OFF-AIR (pre-fader).
TalkOver section for automatic voice/music mix.
The fader also CUT-OFF the monitor output and controls On Air lamp.As option, the faders of the mic 2 and mic 3 channels can be configured to trigger monitor out CUT-OFF and On Air lamp.
