Video signal input connections

NThe MMX switchers do not alter the video signal in any way. The signal output by the switcher is in the same format as the input.

bComposite video input connectors — Connect composite video sources to these female BNC connectors.

The audio level for each input can be individually set, via RS-232 link, to ensure that the level on the output does not vary from input to input. See chapter 4, "Remote Control", for details.

gRCA audio connectors — Connect unbalanced stereo audio inputs to these RCA connectors. See figure 2-11 for an illustration on how to wire the RCA connector.

cS-video input connectors — Connect S-video sources to these 4-pin mini DIN connectors.
