ETC - Electronic Theatre Controls is a lighting equipment manufacturer. Their most significant contribution to entertainment lighting is probably the Source Four ERS, introduced in 1992. ETC makes an entire line of lighting equipment based on the Source Four from the Source Four PAR to the Source Four Revolution™, and produces an LED line of fixtures, the Selador series. In addition to lighting fixtures, ETC also makes lighting control consoles and Dimming Systems. The most widely known ETC dimming system is the Sensor Dimmers, which have recently been updated to Sensor+. However, many electricians prefer the original Sensor™ Control Electronics Module (CEM), as opposed to the CEM+. Their console lines are widely used through the industry and includes consoles like the Express/Expression™, Obsession™, Congo, Congo Jr., Eos/Ion™, and Element™.
