Expanding the highly successful Chameleon Series routing switchers, the Chameleon 256HB/MB has the largest matrix capacity of all Knox switchers. Expandable from 32x32 up to 256x256 with high-performance broadcast specs, the Chameleon 256HB/MB can handle the needs of almost any application. Matrix configurations are assembled in multiples of thirty-two by inserting audio or video cards into a 12U rackframe via the hinged front panel. Audio and video frames are linked together via serial cable; audio-follows-video or audio can be routed separately. All current and stored patterns are backed up in non-volatile memory. The internal mil-spec power supply is 110v/230v auto-sensing; a redundant power supply is optional. The matrix is controlled via front panel controller or RS232. Several command options such as SALVO, batch, and event control are offered. Other control options include computer, remote keypad, third party controllers or all three.

The Chameleon HB/MB is a modular routing switcher expandable to a 256 x 128 audio or video matrix in a 9U rackframe. The matrices may be linked for full audio-follow-video routing. Audio may also be routed independently. The audio and video matrices do not need to be the same size. Matrix configurations are assembled in multiples of sixteen. Insertion cards are plugged into a 9U rackframe via a hinged front panel. The crosspoint matrix is controlled by a simple, yet versatile RS232 protocol. Control options include computer, front panel keypad, remote keypad or all three.

The Chameleon 64i modular audio/video routing switcher is expandable to a 64x64 matrix in a single 9U rackframe. Matrix configurations are assembled by inserting cards onto the backplane in the rackframe. Crosspoint arrays are assembled by increments of eight. These 25 MHz matrix routing switchers route NTSC or PAL video and mono or stereo unbalanced audio. Audio can follow video or can be routed separately.
