RC4M-900SX DMX4dim 4-Channel Wireless Dimmer

The RC4Magic-900SX DMX4dim is a reliable and secure battery-powered 4-channel wireless DMX dimmer for LEDs, lamps, and motors in small props, costumes, and more. Operating in the 900MHz range, which is free of wireless congestion, the 900SX is the fastest and most secure 4 channel dimmer exclusively available for customers only in the USA, Canada, Australia and New Zealand.

The RC4Magic-900SX DMX4dim combines that classic features of the ever popular DMX4dim and takes it into 900MHz. Interference from other wireless devices is literally a thing of the past when using the 900SX series of products, and the result is a signal that’s faster, more secure, and more reliable.

The 900SX DMX4dim provides a total of four dimmers. Like all RC4Magic-900SX 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 RC4 Commander Configuration Software.

The RC4Magic-900 SX DMX4dim features include:

• PWM frequencies Optimizations for power handling, smoothest resolution, eliminating artifacts in video, and eliminating noise in audio systems.
• RC4 Digital Persistence™ A carefully engineered thermal model makes LEDs fade up and down like incandescent and halogen lamps.
• HSL Color Controller Choose to use Hue/Saturation/Level (brightness) control of color if desired.
• RC4 ColorMatch™ Match color palettes and white-balance different LED sources from different manufacturers.
• RC4 Flkr Effects Engine™ Create personalized visual effects, including fire, welding spark, and much more.
• Remote Device Management (RDM) The DMX standard for device configuration, including E1.37 dimmer control extensions.
• RC4 CodeLoader™ Update firmware to add features.  Since 2014, more than 10 new features have been added at no cost to users!

The 900SX Series of products now includes 19-bit dimming, which is eight times finer than 16-bit with a whopping 524,000 steps of resolution. For users, this means exceptionally smooth LED dimming, especially at the bottom end of the curve, which can be problematic. The entire 900 Series also features dimmer curve crossfading to each individual dimmer; this enables users to tweak the dimming curve   256 steps for each separate dimmer output.

The RC4Magic-900 SX DMX4dim is ideal for hybrid-white LED color mixing, when transitioning between different color temperatures of white.
RC4 Digital Persistence™ brings pleasing smoothness to LED dimming.  LEDs have never looked this good.

RC4’s 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. Unlike single-channel DMX control of color from a console, the RC4 HSL Color Controller maintains high ratiometric precision throughout the dimming range.

RC4 dimmers are ideal for video professionals who must avoid banding, blinking and other anomalies created by PWM (pulse-width-modulation) frequencies. All RC4 Series 3 dimmers provide multiple PWM frequencies all the way up to 40kHz for use with slow-motion very-high-frame-rate video work.

The DMX4dim is ideal for use with the dimmers built-in RC4 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.

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 mini-plug wired DMX data port can be used with a range of RC4 DMX cables, including 3-pin and 5-pin male and female XLR adapters. The most common adapter is the RC4DMX5FA with 5-pin female XLR connector.  This port can output DMX 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 DMX6dim to be used as a wired dimmer.

With a wired connection 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.
