[. . . ] The On-Air switch, operated manually or via an opto-isolator circuit, is used to close a set of relay contacts, for external signalisation; it also disables some oscillator and talkback facilities on the Communications Module. Each master has a rotary level pot, a Mute switch, and an AFL button to monitor the after-fade listen signal via the Cue system. The Stereo Master inserts can be switched in and out of the signal path, though the signals are always available on the Insert Send XLRs. The stereo limiter functionally operates exactly as does the limiter on the Group modules, though there is no LINK switch. The stereo output from each module is controlled via a stereo master fader. The PEAK LED monitors both L & R signals, pre-fader, and illuminates if either comes within 6dB of clipping. A mono output is also available, jumper selectable pre or post the limiter. This output has a rotary level control, offering up to 0dB of gain, Mute circuit, and PFL. The signal is a mix of the Stereo Master left and right signals, and is taken pre or post-fader, as determined by the PRE switch. Communications Module In addition to its communication functions, the Communications Module also carries VCA Master faders 3 &4, allowing further input channel level control. Talkback can be routed at any time to the external Talkback Output and to all Group Outputs, also to any combination of Aux buses 1-8, or optionally, any combination of the the 8 group outputs. The signal can also, apart from when the On Air Lock Out LED is lit, be routed to either of the two Stereo Master outputs, and to the studio speakers. There are two sets of studio headphones outputs - Studio Phones and Guest Phones - plus a Studio Speaker output, each with their own level control. whatever the control monitor is receiving), ST1, Aux 8, or an external input (via the Communications Module EDAC). If the Talk To Studio switch is active, the ST1 stereo signal will be routed in mono to the left side of the headphones, and talkback to the right. A Producer-to-Studio input is also available to the phones, with audio input and control via the Communications Module EDAC and EXT Logic D-sub connector. This signal is similarly routed left, with talkback right, whenever it is present. The Studio Speaker outputs can be manually or externally muted; an LED is provided to indicate if external muting is in operation. A speaker dim facility, linked to an internal preset pot for dim level, is also provided. The Communications Module's oscillator, switched in and out via a clear illuminated switch, is routed to the internal tone bus, and also to two sets of balanced outputs on the rear panel EDAC (OSCL & OSCR). A calibration pot controls overall tone level, and a level control attenuates the balanced outputs. The internal tone bus is disabled when the ST1 Module's On Air switch is active. The oscillator can be switched to 100, 400, 1k and 10k Hertz, and an EBU Tone facility is provided to switch the OSCL output such that it is muted for 100ms every 3s.
