Rack Mount Dimmers
The DimmerMaster Rack-Mount family is based on our proven Shoebox technology. They are standard 19-inch, 2U rack units with 2, 4, or 8 channels of DMX & Analog controlled dimming. This allows these dimmers to be used with both DMX controllers like the IQ series and analog controllers like the House Light Controllers simultaneously. Each channel is protected by a circuit breaker conveniently located on the front panel for quick access. A status LED on the front panel indicates the presence of a DMX control signal.
All power connections are made through clamp entries on the back face to internal screw terminals. 0-10V Theatrical 0-10V Analog control signals also enter through the back face to internal screw terminals. The desired DMX control connection option must be specified when ordered: Front 5-pin in and out connectors, Back 5-bin in and out connectors, or internal screw terminals.
Self-adhesive rubber feet included for non-rack applications.

Legacy Modular & Wall-Mount Dimmers
Firmware update available for all legacy 12CFC and 24CFC based dimmer systems.
While we may have discontinued products over the decades, we happy continue supporting our products. It’s part of our “design for maintainability not disposability” philosophy which decreases waste and your total cost of ownership.
This 2020 firmware release allows disabling the Idle Current feature. For incandescent lighting systems, the minimum idle current extends bulb life. But when switching to LED bulbs, the idle current feature can prevent some new solid-state lighting from turning completely off. Now, Idle-Current can be selected with DIP Switch 7 on the control card for all legacy Dove modular dimmer systems as well as the various DM1224 and DM2412 models.
Contact us to have your system updated. Many systems can have the processor reprogrammed (PCB Rev D and later), earlier systems (pre-Rev D) will need a new control card for this feature. Firmware updates will be handled as a repair, which will be $95 plus shipping.
