LumenDimM2micro 2-Channel CRMX Wireless Dimmer (INTernal Antenna)


Product Information

The RC4 LumenDimM2micro is a 2-channel CRMX wireless DMX dimmer for LEDs, lamps, and motors 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 LumenDimM2micro is a battery-powered 2-channel wireless DMX dimmer that combines the best RC4 Harmonized Design features with a genuine LumenRadio TiMo radio transceiver. The LumenDimM2micro includes a built-in radio receiver and two 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, LumenDimM2micro is one of the smallest wireless DMX dimmers on earth. The LumenDimM2micro 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 LumenDimM2micro is not only small, easy to use and reliable, but it has all of the RC4 Wireless dimmer features users know and love:

LumenDimM2_micro_1All 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 19-bit (524,000 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 LumenDimM2micro 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 LumenDimM2micro to be used as a wired dimmer.  In this mode, a comprehensive RDM implementation includes E1.37 dimmer configuration parameters, voltage monitoring, and each dimmer appears as a separate RDM sub-device.

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 both the internal electronics and the connected loads. Dimmers switch on the negative side of the circuit, ideal for common-anode (common positive) LEDs and LED tape. Dimmer output voltage is precisely the DC power input voltage with no appreciable losses within the 10A 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 LumenDimM2micro the smallest wireless dimmer and the smallest wireless DMX receiver available.

The LumenDimM2micro was the dimmer of choice for the lighting team on the Netflix series Stranger Things.
