These channels can be configured as so-called IFB channels. If one pushes a TALK button of such a channel the AUX signal routed to that channel is dimmed by an adjustable degree (“volume ducking”) The (one way) intercom signal is for instance the director talking to the host of a TV show and the AUX signal for instance the “N-1 On Air” signal.
