The new RC4 Series 3 LumenDimM4 is a battery-powered 4-channel wireless DMX dimmer for small props, costumes, and more. A genuine LumenRadio CRMX radio transceiver is built-in, providing an outstanding wireless RDM (remote device management) experience.
Smooth LED dimming
With super-smooth LED dimming, high-power halogen dimming, hobby servo-motor control, HSL color control, a sophisticated effects engine, and DMX input/output (both wireless and wired, including RDM), a single LumenDimM4 could be used to construct a complete miniature moving light, and is barely larger than a matchbox. RC4 understands the demands facing lighting professionals, propsmasters and special effects gurus in live entertainment and motion pictures.
The smallest wireless dimmer in the LumenDim class, the RC4 Series 3 LumenDimM4 provides four 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 any dimmer with a single press of a single button. Device configuration can also be done with Remote Device Management (RDM) .
Four channels are ideal for Red-Green-Blue (RGB), Red-Green-Blue-White (RGBW) and Red-Green-Blue-Amber (RGBA) LED color-mixing. The RC4 Hue/Saturation/Level (HSL) Color Controller delivers best-in-class color 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 HSL Color 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 electrified musical instruments.
The RC4 Series 3 LumenDimM4, 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 LumenDimM4 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.
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.
