S2-OMC
Control Room Monitor Channel
The control room monitor channel is common to every mixer and is used for the monitoring of various sources on the control room loudspeakers (MONITOR) on a 6.35mm stereo jack socket and presenter’s headphones (PHONES) on 6.35mm stereo jack sockets. Front panel control knobs are used to vary the monitor and headphone levels and headphones can be plugged in at the front or the rear of this channel. The control room monitor loudspeaker and headphone levels are variable between 0 (cut off) and 10 (max).
A four way electronically interlocking switch bank selects the source routed to the speakers and headphones from either of two external inputs (EXT 1, EXT 2), the PGM, or AUD output. The buttons illuminate to show the selected source: PGM and AUD are green, EXT 1 and EXT 2 are red. The external inputs can be used for monitoring an off air signal or another studio output.
An illuminated Mute LED shows when a live microphone channel in the control room has muted the speakers, to prevent feedback. Mute outputs on the remote connector of the PGM output channel can be used to remotely illuminate “Mic Live” lights.
AUTO CUE/PFL buttons adjacent to each level control allow the monitoring of PFL when an input channel has been selected to CUE/PFL. In addition, SPLIT CUE/PFL can be selected to the headphones, which will place the selected source in mono in one ear and PFL in mono in the other.
This channel controls the signal conditioning for the talkback input and output and routes these signals to and from the talkback bus. Internal jumpers can be configured to allow talkback to replace or dim the selected source, dimming independently on monitor speakers or headphones.
A Global Talkback system can be configured to allow every contribution point in the control room and studio to communicate with each other via their microphone and headphones.
