LumenDimM4micro 4-Channel CRMX Wireless Dimmer (INTernal Antenna)


Product Information

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.

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.

Super-smooth LED dimming, halogen dimming as well as hobby servo-motor control is a snap with this dimmer that proves small can be powerful. In fact, LumenDimM4micro is one of the smallest wireless DMX dimmer on earth. The LumenDimM4micro uses RC4 OneTouch™ for easy assignment of any DMX channel and dimmer curve to any dimmer with a single press of a single button.  Device configuration can also be done with Remote Device Management (RDM).

The LumenDimM4micro is not only small, easy to use and reliable, but it has all of the RC4 Wireless dimmer features users know and love:

RC4 four channel dimmers are ideal for RGB, RGBA, RGBW and RGBx color mixing applications.  In addition, the RC4 Cross-Fade Controller for warm/cool white color-temperature control delivers best-in-class consistency over the entire dimming range. 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 and RC4 HSL Color Control Engine maintain high ratiometric precision throughout the dimming range.

The LumenDimM4micro provides 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, voltage monitoring, and numerous manufacturer PIDs for access to powerful RC4 parameters.

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.

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, making the LumenDimM4micro one of the smallest wireless dimmer and the smallest wireless DMX receiver available.

The LumenDimM4micro was the dimmer of choice my the lighting team for S&K Pictures on Shazam 2!
