Series Switcher
The Knox Video Technologies RS-III Series matrix switchers are designed to route RGBHV or RGB video signals and balanced or unbalanced stereo audio signals. Available in matrix sizes from 4x8 to 12x8, the series features 300 MHz bandwidth and can be used to route RGB, RGBS, RGsB, HDTV, component video, S-video and composite video signals.

This RS III series also features Knox's exclusive volume and tone attenuation on the matrix outputs. Audio inputs and outputs can be custom configured for balanced or unbalanced devices. In addition to traditional RGBHV analog video and audio outputs, the series offers optional integrated CAT-X transmitters to distribute signals long distances on low cost twisted pair cable. Providing integrated CAT-X transmitters also alleviates cable management issues within the rack while reducing the potential for faulty BNC terminations.
