Routing Switchers

Modular Full-Matrix Routing Switcher Series...by Knox.

The Knox Video Chameleon 64 modular audio/video routing switcher is expandable up to a full 64x64 matrix in a single 8U rack frame*.
These baseband matrix routing switchers route NTSC or PAL video and mono or stereo, balanced or unbalanced audio. Audio can follow video or be routed independently.

Matrix configurations are assembled by inserting cards onto the backplane in the rack frame. Input and output arrays are assembled in multiples of eight. Some common matrix arrays are 24x24 and 32x32.
The Chameleon 64 crosspoint matrix is controlled by a compact RS232 protocol via computer, an optional remote control keypad, or all three.

*Balanced stereo audio (BAS) is available in up to a 32x32 matrix in a single 8U rack frame. Larger BAS configurations require a second 8U rack frame.
