There is only one audio level setting per input and one per
output on an audio plane. The audio level and volume is
shared by the left and right inputs and outputs.
Audio levels and volumes are stored in nonvolatile memory.
When power is removed or restored, settings are retained.
If the audio is set to "follow all", at initial selection (step 2)
the I/O plane and tied I/O buttons light amber. When an
input or output button is held (step 3), the plane blinks red.
Adjusting the Output Audio Volume
The audio output level of each output can be displayed and
adjusted through a range of 64 steps (1 dB per step 0% to 100%).
The audio level can be adjusted from the front panel, RS-232, or
through Ethernet. Adjustment is attenuation only.
