SW RGB and YUV A Switchers • Installation2-8
The audio level for each input can be individually set, via the front panel or
under RS-232 control, 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.

RGB and component video outputs —
RGB models — Connect an RGBHV, RGBS, RGsB, RsGsBs, or component
video display or other device to these BNC connectors. Connect the cables as
shown in figure 2-8.
SW6 YUV A — Connect a component video, RGsB, or RsGsBs video display
or other device to these BNC connectors. If you are not switching digital
audio, you can use the Digital Audio output BNC (

) to output the sync
plane of RGBS video. Connect the cables as shown in figure 2-8.
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.

Balanced or unbalanced audio output connectors (SW2 RGBHV A,
SW4 RGBHV A, and SW6 RGBHV A only) — These 3.5 mm, 5-pole captive
screw connectors output the selected unamplified, line level audio. Connect
audio devices, such as an audio amplifier or powered speakers to these
connectors. See figure 2-10 to properly wire an output connector.

CAUTION
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative
(-) terminal will damage the audio output circuits.
By default, the audio output follows the video switch. Audio breakaway,
which can be commanded under RS-232 control via the SIS or Windows-based
control program, allows you to select from any one of the audio input sources.
