Figure 2-3 — SW 12SVA RCA S-video switcher with audio on RCA connectors

Video input and output connections (video models only)

1Composite video inputs (composite video (V) switchers only) — For each input, connect a composite video source to one of these BNC connectors.

2S-video inputs (S-video (SV) switchers only) — For each input, connect an S-video source to one of these 4-pin mini DIN connectors.

Composite video outputs (all video switcher models) — Connect composite video displays or other devices to these BNC connectors for each composite video output.

S-video output (S-video (SV) switchers only) — Connect an S-video display or other device to this 4-pin mini DIN connector for the S-video output.

Audio input and output connections (audio models only)

The audio level for each input can be individually set, via the front panel or RS-232, to ensure that the level on the output does not vary from input to input. See chapter 3, Operation, and chapter 4, Remote Control for details.

By default, the audio follows the video switch. Audio breakaway, which is commanded via the front panel (see chapter 3) or under RS-232 control via the SIS or Windows-based control program, allows you to select from any one of the audio input sources. See chapter 3, Operation, and chapter 4, Remote Control for details.

CAUTION

The captive screw connector can easily be inadvertently plugged partially into one receptacle and partially into an adjacent receptacle. This misconnection could damage the audio output circuits. Ensure that the captive screw connector is plugged into the desired input or output.

5Balanced or unbalanced audio input connections (captive screw connector audio (A) models only) — Each input has a 3.5 mm, 5-pole

captive screw connector for balanced or unbalanced stereo audio input. Connectors are included with each SW AV Series switcher, but you 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.
