City Theatrical QolorFLEX 4x10A Dimmer, 12V

These units are b-stock from City Theatrical.

The City Theatrical QolorFLEX 4x10A Dimmer, 12V is a compact, self-contained four-channel DMX/RDM dimmer built for powering and controlling 12V LED loads in theatrical, event, and touring environments. It combines the functionality of the 4x10A Dimmer with higher output power and an integral 40A power supply, reducing the need for external power distribution and making it easier to mount directly to scenery or practicals.

Designed for surface mounting, the angled control surface stays visible and reachable when installed in corners or tight spaces, which is especially useful for quick address changes, troubleshooting, and on-site adjustments.

Control, Addressing, and On-Board Setup

Each output can be set with individual DMX addresses for flexible patching, and the unit is fully RDM enabled for remote configuration and device management within an RDM-capable lighting network. Local configuration is streamlined with BCD DMX addressing (9POS), curve selection (4POS), and a dedicated LED curve selection switch. Individual bump buttons and LED indicators provide fast channel checks and clear status at a glance.

Power and Protection for Demanding Loads

Built to handle real-world production conditions, the dimmer provides four output channels with individual over-current and over-temperature protection per channel. For smooth, camera-friendly fades and consistent looks, it supports 16-bit dimming resolution, multiple dimming curves, LED modes, and LED smoothing modes (four settings) to help reduce stepping and flicker in sensitive applications.

Ideal Applications

This unit is well suited for scenic and architectural practicals, integrated set pieces, and portable rigs where you want reliable multi-channel control, simplified power, and on-device access without dedicating extra space to separate power supplies or distro.
