ETC Dimmer Doubler

The ETC Dimmer Doubler is a stage lighting breakout adapter that converts a male stage pin output into two female L5-15 twist-lock connectors, allowing two lighting fixtures to operate independently from a single dimmer. It is designed for situations where you need more controllable circuits without adding dimmers or pulling additional cable.

Looking for a way to double your dimming control capacity without having to add to your dimmer inventory? Looking to cut in half the amount of dimmers you have to take on the road? An ingenious device from ETC solves those lighting problems: Dimmer Doubling (sometimes referred to affectionately but unofficially as 'multiplexing'). The Dimmer Doubler allows two lighting fixtures to operate independently using only one dimmer. The two lighting circuits function independently, as if they were connected to separate dimmers. Simply run one circuit from any 120V, 60Hz Sensor or Unison dimmer to a conventional outlet. Connect a Dimmer Doubler, and plug in two Source Fours with 77V HPL lamps.... That's it! The two lighting circuits work as if each had its own assigned dimmer.

Why Use Dimmer Doubling

• Same dimmers, twice the control for conventional fixtures when you need more independent channels.
• Less wiring, helping reduce cable runs and congestion in racks, raceways, and on tour.
• Lower installation costs for upgrades where adding new dimmers or infrastructure is impractical.
• No loss of dimmer-per-circuit control, each circuit behaves as if it were on its own dimmer.

Applications

• Easily increase dimmer circuit counts for renovations without additional construction
• Adding dimmer circuits to existing installations for specials or more complex lighting plots
• Doubles dimmer circuit counts for touring shows

Connectors and Compatibility Notes

This unit is configured as male stage pin to two female L5-15 twist-locks. The example workflow referenced above specifies use with 120V, 60Hz Sensor or Unison dimmers and conventional fixtures such as Source Fours with 77V HPL lamps, supporting independent control of two circuits from one dimmer.
