The RC4 Series 3 DMX2micro is — by far — the smallest wireless DMX dimmer on earth. 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. Device configuration can also be done with Remote Device Management (RDM) and RC4MagicPC Remote Configuration Software.
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. In addition, RC4 ColorMatch™ on the DMX2micro makes it easy to calibrate intensity between two light sources.
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. LEDs have never looked this good.
Many 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.
Wired DMX data port
The DMX2micro, 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 DMX2micro 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.
With all that’s going on inside RC4 Series 3 dimmers, a means of routing signals within the device is needed. RC4 HotPatch™ is the answer. In the default mode, dimmers are directly controlled by DMX channels they are assigned to; the flicker effects engine and HSL color controller are bypassed. From there, RC4 HotPatch™ provides numerous other configurations, enabling internal processes in a variety paths. When using RC4Magic Series 3 dimmers, RC4MagicPC allows these configurations to be further customized by individually routing dimmers to particular data sources.
The internal wireless DMX receiver operates identically to the RC4Magic Series 3 DMXio in receiver mode. 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 DMX2micro the smallest wireless dimmer and the smallest wireless DMX receiver available.
An 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. 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 10A total power handling limit of the device.
