RC4 Custom Pixel Profiles™ is a patented method for controlling many pixels with fewer DMX channels than are needed for 1:1 mapping.  For example, a typical pixel driver by others requires a full DMX universe (512 channels) to control 170 RGB pixels.  Using RC4 pixel profiling, 1000 or more pixels can be controlled with less than a full universe, all completely under the control of the lighting designer and DMX console.
