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.
