The RC4Magic DMX4dim is a compact, easy to use, secure, battery powered 4-channel wireless dimmer that makes dimming (RGBW-) LEDs, lamps, motors in small props, costumes and more effortless. The DMX4dim includes a built-in radio receiver with internal antenna.
It includes 19-bit dimming, which is eight times finer than 16-bit with a whopping 524,000 steps of resolution. The digital persistance for ISL dimming curve simulates the behavior of a tungsten lamp for LED with no visible stepping.
For users, this means exceptionally smooth LED dimming, especially at the bottom end of the curve, which can be problematic.
The RC4 DMX4dim provides four versatile dimmer outputs. 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.
RC4 Private IDentities™ securely encrypts your wireless data transmission and is used exclusively in the RC4 Magic series.
Device configuration can also be done with Remote Device Management (RDM) and RC4MagicPC Remote Configuration Software.
HSL Color Controller
Three 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 dimmers makes it easy to calibrate the color rendering between two light sources.
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 DMX4dim, 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 DMX2dim 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.
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.
This dimmer can control the speed and direction of DC motors, stepper motors and the position of hobby servo motors.
For direction control, a second dimmer output can be used to flip a relay that reverses the DC motor connectors – polarity of power directly controls spin direction.
Screw terminals are provided for connection of the power supply (+/-DC IN) and load devices (DimA, DimB, DimC, DimD). 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.
