SPECIFICATIONS
The OMX-4x4 Switchers are flawlessly designed 4 x 4 matrix routers for seamless routing between any one
of four inputs to any or all of the four outputs. Since audio-follows-video, each switch selected controls
both video and audio. As a true matrix switcher, you may send any input signal to any output.
Vertical Interval Switching provides glitch free transitions between synchronized sources.
The 4x4 models are controlled from the front panel using “output” assignment switches with LED con-
firm. Additionally, a 9-Pin Serial Control Port Located on the rear panel is provided to interface your PC
with the switcher. Included Software is provided for switcher control from any standard PC.
