The RGBW4C IR is a 32 channel RGB, RGBW or RGBA LED controller. It is designed to control 3 or 4 channel groups of LED devices where channel 1 is red, channel 2 is green, channel 3 is blue and channel 4 is white or yellow. Up to 8 LED devices or device groups can thus be controlled independently with four device keys. All LED fixtures or fixture groups must be set to operate in DMX mode addressed on four channels to allow independent control. The fixture control panel includes 9 "Static Color/Chase" buttons for direct access: these contain pre-installed color settings and chase programs, 3 user-programmable color preset buttons, 4 multi-function faders for controlling RGBW saturations during operation, and the chase programs "Speed", "Fade Time" and "Master Dimmer". A row of 8 buttons is also used to select the operation mode, including RGB fade, auto, hue, chase, music control, strobe effect, manual RGBW and dimming modes. The RGBW4C is one of the easiest to use and most versatile LED controllers on the market today. It is ideal for DJs, nightclubs, lounges, bars and anyone who wants to conveniently control their LED PAR cans, strips, floodlights and panels.
