Extron electronic SW YUV A, SW RGB manual Output, RGB and component video outputs

Installation, cont’d

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.

3Digital audio input connections (SW6 YUV A only) — Each input has a female BNC connector for a digital audio input. If you are not switching digital audio, you can use this connector to input the composite sync plane of RGBS video.

Output

4RGB 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 ( 6 ) 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.

5Balanced 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. See chapter 4, Remote Control for details.
