Lighting boards are the control center of theatrical lighting. In the case of DMX Lighting boards the definition can be expanded to include any device with DMX technology incorporated into it such as, fog machines, hazers, lasers and other special effects equipment. The lighting boards are historically placed at the front of the house in control booth so that the stage and lighting effects can be seen as they happen. More modern applications will have the lighting changes accomplished by software driven computer programs. This allows the lighting technician to make faster and more detailed changes that were possible under manual control.
