Used Lighting Consoles
Lighting consoles are electronic devices for controlling multiple lights simultaneously from one point. Dimmers for controlling lighting intensity, automated lighting, fog machines and hazers are some of the special effects lighting devices controlled by a lighting board or lighting desk (other terms for lighting consoles).
An electronic control protocol is used by lighting consoles to communicate with other devices in the lighting system. Some of these are DMX512, ACN and DMX-512-A. New protocols are being introduced as more sophisticated lighting systems become available.
In the entertainment industry, where theatrical lighting design is mostly used, lighting consoles are usually found in the control booth, auditorium or the foyer. For this application, the most common protocol is DMX512.
Lighting consoles are available in different sizes and complexities. A preset board, a conventional console for basic lighting systems, is used mostly for small setups. However, DJs may complement it with more advanced hybrid consoles. A moving light controller works with dimmers for controlling ordinary lighting. It also provides additional controls for automated stage lighting (also called intelligent lighting) to produce very complex lighting effects. Other types of lighting consoles include memory consoles, personal-control based controllers, and remote focus unit.
The light board operator (also called the light op or board op) is the person who operates the lighting console. Depending on the scale and type of production, he can be the lighting designer or the stage manager. He or she is responsible for conventional or automated lighting fixtures as well as controlling video.
