My college theatre is about to start its new season (well, my work will begin shortly....) and I would really like to update the comm system. Currently, we are using an old intercom donated by another local college's theatre department. We have a headset for lighting and for the director. Right now the base hub for the system sits up in the lighting/sound booth and the cable for the director's head set is run out through the window...I would like to use the system we have right now, but am looking to expand it. I have included a rough sketch of the theatre's layout for reference.
