The RC4 Series 3 LumenDimM2
is a miniature wireless DMX receiver and 2-channel DC dimmer for use with LumenRadio CRMX transmitters. It provides full RDM support. The device operates from 6V to 35VDC, to a maximum total load of 16A. All features of RC4 Harmonized Design are included: high power, high resolution, modes for video and audio applications, dual-color cross-fade control, built-in effects engine, and more.
The most economical wireless dimmer in the LumenDim class, the RC4 Series 3 LumenDimM2 provides two dimmers. Like all RC4 Series 3 devices, it includes a built-in radio receiver and uses RC4 OneTouch™ for easy assignment of any DMX channel and dimmer curve to either dimmer with a single press of a single button. Device configuration can also be done with Remote Device Management (RDM) .
Two channels are ideal for warm/cool (or other 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. 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 electified musical instruments.
Two dimmer outputs also provide an effective experience with the RC4 Wireless Flkr Effects Engine. Using DMX channels for control, dynamic animated effects are easily and quickly created — this is not a canned effect generator, it is a tool for creating unique looks to suit any need. Effects can also be stored and recalled, and a saved effect can be enabled on power-up. This provides a means of creating and using custom effects without an external DMX controller — perfect for standalone displays in retail, trade shows, and more.
The RC4 Series 3 LumenDimM2, and all RC4 Series 3 dimmers, 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 LumenDimM2 to be used as a wired dimmer. Either wireless or wired, 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 with signal flow following a variety of paths.
The RC4 Series 3 LumenDimM2 includes all RC4 Series 3 Harmonized Design features, including:
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 miniplug port can be used with a range of RC4 DMX cables, including 3-pin and 5-pin male and female XLR adaptors. The most common adaptor is the RC4DMX5FA with 5-pin female XLR connector.
