The RC4 LumenDimM4micro is a 4-channel CRMX wireless DMX dimmer for LEDs, lamps, motors, and more, in small props, costumes, and more. The inconspicuous circuit-board assembly can easily be hidden in the smallest spaces, even in hair and fabrics.

Two versions available:

  • with internal antenna
  • with external antenna (included)

The LumenDimM4micro is a battery-powered 4-channel wireless DMX dimmer that combines the best RC4 Harmonized Design™ features with a genuine LumenRadio TiMo radio transceiver. The LumenDimM4micro includes a built-in radio receiver and four pulse-width-modulation (PWM) dimmers. Additionally, any number of RC4 LumenDim devices can be used in a LumenRadio wireless DMX system.

It´s available with internal antenna or external antenna (included in delivery) for range extension. Each micro purchase includes a 6-pin connector with bare wire ends.

RC4 digital persistance iconIt includes 19-bit dimming, which is eight times finer than 16-bit with a whopping 524,000 steps of resolution. The digital persistance for ISL dimming curve simulates the behavior of a tungsten lamp for LED with no visible stepping.

The DMX6dim also features dimmer curve tweaking to find the most visually linear and pleasing response with any LED technology being used.


RC4 wireless key featureThe RC4 LumenDimM4micro provides two versatile dimmer outputs.  Like all RC4Magic devices, it includes a built-in radio receiver and uses RC4 OneTouch™ for easy assignment of any DMX channel and dimmer curve to any dimmer with a single press of a single button.


RDM (remote device management) for RC4 dimmersDevice configuration can also be done with Remote Device Management (RDM) wireless or wired.

HSL Color Controller

Two channels are ideal for hybrid-white LED color-mixing, to transition between different color temperatures of white.  The RC4 Hue/Saturation/Level (HSL) Color Controller delivers best-in-class color consistency over the entire dimming range, ensuring precise mix ratios even at very low dimmer levels using 16-bit (65,536 step) dimming.  Unlike single-channel DMX control of color from a console, which is limited to 256 steps and becomes heavily quantized at low levels, the RC4 HSL Color Controller maintains high ratiometric precision throughout the dimming range.


RC4 wireless key featureIn addition, RC4 ColorMatch™ on dimmers makes it easy to calibrate the color rendering between two light sources.


RC4 wireless key featureMany pulse-width-modulation (PWM) dimmers look good to the human eye, but produce banding, blinking, and other anomalies when used with video cameras. For this reason, all RC4 Series 3 dimmers provide multiple PWM frequencies.  Low frequencies are most efficient, ideal for high-wattage incandescent lighting. Mid frequencies improve the appearance of LEDs by eliminating visible strobing in human peripheral vision.  High frequencies eliminate video artifacts.  And finally, supersonic PWM frequencies, though least efficient for power handling, provide PWM dimming without audio interference when used near microphones and electrified musical instruments.


RC4 wireless key featureThis dimmer can control the speed and direction of DC motors, stepper motors and the position of hobby servo motors.

For direction control, a second dimmer output can be used to flip a relay that reverses the DC motor connectors – polarity of power directly controls spin direction.


The LumenDimM4micro, and all RC4 Series 3 dimmers, provide a wired DMX data port.  In most cases this port is used to output data to nearby fixtures including fog machines, moving lights, and projector dousers.  The DMX port can also be configured as a DMX input, allowing the LumenDimM4micro to be used as a wired dimmer.  In this mode, a comprehensive RDM implementation includes E1.37 dimmer configuration parameters, numerous status sensors (voltage, temperature, current), and each individual dimmer appears as an RDM sub-device.

The RC4 DMX miniplug port can used with a range of DMX adaptors, including 3-pin and 5-pin male and female XLR connectors.  The most common adaptor is the RC4DMX5FA with 5-pin female XLR connector.


A small Amp MTA-100 6-pin connector is provided for connection of power supply and dimmer outputs.  Each device is provided with one connector with 6″ (15cm) leads. Input DC powers the internal electronics. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LEDs and LED tape. The positive side of external loads (LEDs, lamps, etc.) are wired back to the positive side of the power supply or battery.  Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 6A peak power handling limit of the device. Continuous running power is limited to 6A due to the safety rating of the Amp MTA-100 connector pins.
