Extron electronic System 7SC manual Audio inputs

2Adjustable level audio output (Variable) — For adjustable level audio output, connect an audio device, such as an amplifier, or mixer, to this

3.5 mm, 5-pole captive screw connector. Follow the diagram and warning shown in 1 for correct wiring. See chapters three and four for details on per- channel input gain adjustments and on audio breakaway.

The overall level for this output is controlled by the front panel Volume knob. As shown in the diagram below, the volume adjustment applies an attenuation after the per-input gain adjustments discussed in 1 are applied. For this output the volume level adjustments apply to all the inputs and cannot be set separately per input channel.

The Fixed audio output and the Variable audio output are simultaneously active, therefore two devices can be connected at the same time. Both outputs carry the same input’s audio signal.

3Output 15-pin HD connector — Connect a display device to this female VGA-style connector for RGB output.

Both outputs are buffered and can be connected simultaneously. The sync format will be the same for both outputs.

4Output BNC connectors — Connect coaxial cables from another display device to these BNCs for one RGBHV, RGBS, or RGsB/RsGsBs video output as follows:

Both outputs are buffered and can be connected simultaneously to two different displays. For RGB inputs, the output signal’s sync format is based on the format of the incoming RGB signal. For all other types of inputs, the user selects the output sync format. The sync format will be the same for both outputs.
