The City Theatrical 5750 QolorFLEX 4x10A is a professional, DMX-controllable 12-volt DC dimmer designed primarily for low-voltage LED lighting fixtures in theatrical, architectural, and entertainment lighting applications. This compact, four-channel dimmer pack provides independent control over four separate 10-amp circuits, allowing lighting designers to manage multiple strings of 12V LED tape lights, modules, or other low-voltage fixtures with precision. It operates on the DMX512 protocol, enabling seamless integration into larger lighting control systems used in stage productions, concerts, themed attractions, and permanent installations. The unit converts standard AC mains power to regulated DC output, applying smooth, flicker-free dimming curves to each channel based on the incoming DMX values.

A key feature of the QolorFLEX dimmer is its focus on performance with LED loads. It provides stable current regulation to prevent color shift and maintain consistent brightness across the dimming range, which is a common challenge with low-voltage LEDs. The dimmer supports various DMX addressing modes and can be set to respond to different DMX channel footprints (e.g., 1 channel per output for intensity only, or 3 channels per output for RGB control). Its rugged metal housing is designed for reliability in demanding environments and includes ventilation for thermal management. The front panel features status LEDs, DIP switches for address configuration, and test buttons for verifying output without a DMX controller.

Installation is straightforward, with terminal blocks for both AC power input and the DC output to fixtures, as well as XLR connectors for DMX input and output (loop-through). The dimmer is often used to empower custom LED installations where individual control of color or intensity is required, providing a robust and professional-grade alternative to consumer-grade LED drivers. The City Theatrical QolorFLEX 4x10A Dimmer exemplifies a specialized tool that brings the precision and reliability of professional lighting control to the growing domain of low-voltage LED illumination.
