The control booth, control room, lighting box, technical booth, or just booth to theatre or television technicians is the area designated for the operation of technical equipment, and is sometimes the location of the deputy stage manager's station as well as the lighting controls and sound board. Often one or two followspots are located in the booth as well. Generally it is an enclosed space with a large sliding window with a good view of the stage. In a proscenium theater, it is centered in the back of the house. It might be on the ground floor, but is sometimes placed at the balcony level. It is designed to allow lighting and sound operators to be able to see the performance, without being in the auditorium itself. This means that they are free to talk to their colleagues in the booth, and also the Stage management team and other crew members via the communications headset. A booth that is sealed to the auditorium also allows for noisier equipment to be used, in particular computers and computer-based lighting desks, which require built-in fans in order to work properly. The downside to having a sealed booth is that it can be difficult for the sound engineer to mix without being able to hear what is actually happening on stage. In this situation a separate table may be set up in the house for the sound engineer.
