The stage sound control room is the control center of the sound system. The sound engineer can adjust the sound of the sound system in the control room, and can understand the situation on the stage through the observation window, and operate and control the sound equipment in a timely and accurate manner to achieve the best performance. Usually the sound control room is set up behind the auditorium. The observation window should be large enough to observe the entire stage. The observation window should be openable so that the sound in the hall can be heard directly. In addition, in order to avoid strong and weak electrical interference, the audio control room should be as far away as possible from the lighting control room.
