Dimmer Doubling

A feature on the ETC Sensor dimmer racks where a Dimmer Doubler™ can be used to split one dimmer in the rack into two circuits on the mounting position.


ETC Products -- Dimmer Doubling

Requirements for Dimmer Doublers are:
  • Source Four™ fixtures with 77V lamps and L5-15 male plug
  • Sensor 120V dimmers (including Unison) with CEM or CEM+

  • The lamp burner of each fixture must have a screw removed to accept the additional, non-conducting pin of the 77V lamp (similar to the pin on the 750W lamp, but on the opposite side).
  • The Dimmer Doubler has two L5-15 connectors for output and ETC says existing cable should be modified all the way to the fixture to connect to the doubler unit not vice versa.
  • Only one 77V 550W lamp per side is allowed.
