cSync Impedence switches (168, 1212, and 1616 matrix sizes) — The Sync Impedance switches compensate the output 1 through 8 impendance for different cable types and lengths. Each switch provides the option of selecting either 50 ohms or 75 ohms. The 50 ohms position is required only when a sync problem is encountered. The normal position is 75 ohms.

NAn input producing an out-of-sync display — a display that is rolling vertically and/or tearing horizontally — could indicate an impedance problem.

dAudio inputs — Connect audio sources to the 5-pole captive screw connectors.

CTurn off power to the input and output devices, and disconnect their power cords.

NThe MVX matrix switchers can also switch component video, S-video, or composite video with the appropriate adapters.

aVideo inputs — Connect RGB video sources, as appropriate to your switcher's video format and matrix size.

bVideo outputs — Connect RGB video displays, as appropriate to your switcher's video format and matrix size.

NMost laptop or notebook computers have an external video port that may require special commands to output the video to that connector. Also, a laptop’s screen shuts off once the external video port is activated. See the computer’s user’s guide for details, or contact Extron for a list of common laptop keyboard commands.
