Knox Video’s family of high performance, fixed-matrix routing
switchers are extremely versatile, easy-to-use and very affordable.
Housed in an ultra-thin rackmount chassis, they accept and route, on
the vertical interval, virtually any baseband video signal. Our switchers
even route off-the-air and non-timebase corrected video. They also route
balanced or unbalanced stereo audio. The audio follows the video or
the audio can be routed independently.
Each of the switchers offers easy manual control via front panel operation.
Our routing switchers can also be controlled remotely by a computer,
by a Knox Video RS Remote Controller and/or by a Knox Video Remote Keypad
Controller. Front panel LED’s indicate the current routed pattern
at all times. An internal battery holds and restores the current pattern
in case of power interruption. Crosspoint patterns may be programmed,
stored, and later recalled.
