2-7 System 7SC • Installation
2 Adjustable 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.
3 Output 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.
4 Output BNC connectors — Connect coaxial cables from another display
device to these BNCs for one RGBHV, RGBS, or RGsB/RsGsBs video output
as follows:
RGBS RGBHV RGsB (Sync on Green)
RsGsBs (output only if input is RsGsBs)
R G B H/HV V R G B H/HV V R G B H/HV V
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.
