It takes input from an operator and existing program and sends it down a control cable to the dimmers. It is important that the console and dimmers are able to speak the same language. Control boards can range from small shoe box sized boards to large Microprocessor based consoles, which can drive hundreds of dimmers. Dimmers take the main power from the electric source at your performance space and send out various amounts of power through the individual dimmers. The control console's signal is what determines how much power goes through which dimmers and when.
Dimmers come two different ways.
Rack mounted dimmers are usually for larger systems and are usually permanently mounted in the performance space. Dimmer packs tend to be for portable or semi-portable applications and can generally be carried by one person. The distribution system is the wiring system that takes the power from the dimmers to the fixtures. A distribution system can consist of wireways, plug-in boxes and connector strips , or can be as simple as a set of extension cords if conditions permit. It's quite all right.
