I have a few questions regarding intercoms (clear-com, telex, etc)
Do you prefer to have the system wired to the green room/dressing rooms differently than that of control booth and tech? Different channel or something. (I know most actors disregard what's said on comms cause they mostly hear cues being called
Do some systems (especially telex. That's the one I'm most familiar with) have an option to function like a god mic if connected to soundboard or PA speakers. If you can then is everyone that speaks over headset can be heard over PA speakers. How can it be done so only Stage Manager can be heard over PA speakers (only when desired)
Can you wire speakers (temporarily) for green room/dressing rooms to call actors separate from calling cues.
Do non-professional and professional theatres all have permanent systems?
If a company has to bring their own system do they just simply run cable all the way to the booth and green room/dressing room for everyone to hear the calls
