has a 75 ohm output impedance. Slide the switch to the right (HIGH) when connected to a
higher output impedance.

VIDEO IN and OUT Jacks
The jacks provide "feed through" of a video signal when it is desireable to display the
video signal on more than one monitor. A standard 1.0 volt p-p video signal applied to the
VIDEO IN jack will also appear at the VIDEO OUT jack. The video signal from a computer
should be fed to the VIDEO IN jack via a shielded cable and RCA type phono plug.
8.
AUDIO IN and OUT Jacks
Those jacks provide the same function for audio that the VIDEO IN and OUT jacks
provide for video. An audio signal from a computer should be fed to the AUDIO IN jack
via a shielded cable and RCA type phono plug.
