The RC4 LumenDimM2 is a miniature, battery-powered 2-channel wireless DMX dimmer on the CRMX platform that is ideal for dimming LEDs, lamps, and motors for use in small props, costumes, and even more. The LumenDimM2 provides an outstanding wireless RDM (remote device management) experience, as well as super-smooth LED dimming, high-power halogen dimming, hobby servo-motor control, a sophisticated effects engine and more, all at an economical price.
Like all RC4 Series 3 devices, the LumenDimM2 includes a built-in radio receiver and uses RC4 OneTouch™ for easy assignment of any DMX channel and dimmer curve to either dimmer with the press of a single button. Device configuration can also be done with Remote Device Management (RDM).
The LumenDimM2 includes all of the RC4 features that users know and love, including:
- RC4 Flkr Effects Engine™
- DMX data in and out
- RC4 HotPatch™
- 16-bit dimming with multiple PWM frequencies
- High-efficiency 6V-35VDC voltage input range
All two channel dimmers are ideal for warm/cool white or dual-color LED color-mixing. The RC4 Cross-Fade Controller delivers best-in-class color mix consistency over the entire dimming range, by ensuring precise primary color ratios even at very low dimmer levels using 16-bit (65,536 step) dimming. Unlike single-channel DMX control of color mix from a console, which is limited to 256 steps and becomes heavily quantized at low levels, the RC4 Cross-Fade Controller maintains high ratiometric precision throughout the dimming range.

The warmth of incandescent lighting has long been favored by lighting designers, and for good reason; natural filament persistence ensures smooth fades even when control resolution is relatively coarse. RC4 Digital Persistence™ brings this same pleasing smoothness to LED dimming, with a range of eight persistence periods emulating a variety of halogen lamp sizes.
The LumenDimM2 also features multiple dimmer curves. They include Non-Dim, Non-Dim Inverted, Linear, Linear Inverted, Inverse-Square-Law (ISL), ISL inverted, servo motor pulse clockwise and servo motor pulse counter-clockwise.
Screw terminals are provided for connection of the power supply (+/-DC IN) and load devices (+/-DimA, +/-DimB). The supply powers both the internal electronics and the connected loads. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LED tape. Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 16A total power handling limit of the device.
The DMX mini-plug port can be used with a range of RC4 DMX cables, including 3-pin and 5-pin male and female XLR adapters. The most common adapter is the RC4DMX5FA with 5-pin female XLR connector.
