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

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

Audio input and output connections
8
Input 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 2-4 to 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.

Audio 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 2-5 to properly wire an
output connector.
