The SYNCHRONATOR ColorControl is a device for mixing two channels of audio into an RGB Triphonic signal. Its output is to be connected to a SYNCHRONATOR AV or HD device in order to create a video signal.
The ColorControl has two controllers for hue and two sliders for setting the saturation for each input channel.
Depending on the hue and saturation settings, the signal is proportionally divided over the RGB Triphonic outputs.
Unlike regular audio equipment, which works fine for sound within the hearable range, the ColorControl can handle frequencies up to 4 MHz without affecting the quality of the signal.
