Output A and Output B, composite video outputs — Connect composite video display, recording, or transmission devices to these BNC connectors.

The outputs of the two connectors are identical to each other and to the decoded S-video output 7 .

Output C, S-video output — Connect an S-video display, recording or transmission device to this 4-pin mini-DIN connector. The output of this connector is identical to the encoded composite video outputs 6 .

Audio input and output connections

8Input 1, 2, 3, and 4 audio inputs — Each input has a 3.5 mm, 5-pole captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each SVS 100, but the user must supply the audio cable.

See figure 2-4to wire a connector for the appropriate input type and impedance level. High impedance is generally over 800 ohms.

The audio level for each input can be individually set, via the front panel or RS-232/RS-422, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, and chapter 5, Serial Communication, for details.

9Audio output — This 3.5 mm, 5-pole captive screw connector outputs the selected unamplified, line level audio. Connect an audio device, such as an audio amplifier or powered speakers. See figure 2-5to properly wire an output connector.
