Does anyone know how I can use a small mixer to make a stage intercom system?
We have one lighting guy, one sound/audio engineer, a computer guy who projects stuff onto the big screen behind the performers and one stage manager.
I want to be able to talk to them all and have the system controlled by a small manual mixing console instead of buying a complete intercom system.
There is an audio snake which runs backstage that we could use, but how many channels do I need if I want a talk back system like that (headphone and mic) for each person.
My theory was that the microphone which is attached to the headphone can just be plugged into channel 1 and the headphone into the AUX send. Would this work? What about the mains, can they be used or not?
Please help me out here.
