Concept
Lighting control console
Résumé
A lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth.
All lighting control consoles can control dimmers which control the intensity of the lights. Many modern consoles can control Intelligent lighting (lights that can move, change colors and gobo patterns), fog machines and hazers, and other special effects devices. Some consoles can also interface with other electronic performance hardware (i.e. sound boards, projectors, media servers, automated winches and motors, etc.) to improve synchronization or unify their control.
Lighting consoles communicate with the dimmers and other devices in the lighting system via an electronic control protocol. The most common protocol used in the entertainment industry today is DMX512, although other protocols (e.g. 0-10 V analog lighting control) may still be found in use, and newer protocols such as ACN and DMX-512-A are evolving to meet the demands of ever increasing device sophistication. Some lighting consoles can communicate over a Local IP network infrastructure to provide control over more scalable systems. A common protocol for this is ESTA E1.31 sACN (pronounced: streaming A.C.N.) or Art-Net.
Consoles vary in size and complexity, from small preset boards to dedicated moving light consoles. The purpose of all lighting consoles, however is the same: to consolidate control of the lights into an organized, easy-to-use system, so that the lighting designer can concentrate on producing a good show. Most consoles accept MIDI Show Control signals and commands to allow show control systems to integrate their capabilities into more complex shows.
Preset boards are the most basic lighting consoles—and also the most prevalent in smaller installations. They consist of two or more identical fader banks, called scenes.
