[. . . ] There are two sets of studio headphones outputs - Studio Phones and Guest Phones - plus a Studio Speaker output, each with their own level control. The input to these three can be CRM (ie. 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. A slate facility is also provided - the oscillator signal can be routed to the Direct Output of every input module, the talkback signal can be similarly routed, or the two can be routed simultaneously (though the oscillator frequency will be automatically set to 30Hz). Two Option switches are provided, controlling relays available via the Communications Module External Logic D-type connector, for remote control of external devices, lamps etc. The switches also drive talkback contacts for external use via an EDAC connector, with Call LEDs accessed via the Logic D-sub connector. Monitor Module The Monitor Module provides facilities for mono and stereo monitoring of many internal and external sources, as well as VCA master faders 1 and 2 for adjusting input module gain. Any one of eight external or six internal sources can be selected for monitoring. External sources are taken from a rear-panel 90-way EDAC connector, whilst internal jumpers allow combinations of the following to be assigned as the six internal sources: Groups 1 to 8 (mono) The main stereo mixes of the ST1 and ST2 Modules (stereo) The mono mixes of the ST1 and ST2 Modules (mono) Aux 1 to Aux 6 (mono) Aux 7 and 8 (stereo) Stereo sources are normally sent in stereo to the monitor bus. With the MONO SOURCE L & R switches, however, either or both the left and right sides of a stereo monitor source can be sent in mono to both sides of the monitor bus. Monitor outputs are via two sets of Monitor Speaker outputs, and to a headphones output. Both Cue and Monitor signals can be simultaneously heard in the headphones by depressing the H/P SPLIT button. The monitor signal is sent (in mono, summed if it is a stereo source) to the left side, and the cue to the right side. The ALT switch is used to switch between the two sets of monitor speaker outputs. [. . . ] '(7(&7 75, 0 3$1 &XW%RRVW 7 3($.
