The first time power is applied to the audio board, the following conditions exist:
No inputs are connected to outputs.
All inputs are set for professional levels.

Refer to the sample display screens on this page. The Configure Audio menu

Audio1 or 2 = which audio plane is to be configured
Audio plane #2 is not available as of this date.
INP or OUT = configuration is for an input or an output
1 thru 8 = which, of eight inputs or outputs, is to be configured
Lvl = CONSUMER or PROFESSIONAL means the level to be set is for
Consumer or Professional audio equipment
(Typical levels: Consumer audio
≈
6v p-p; Professional audio
≈
30v p-p)
When setting the Input (INP) gain:
>L, R, or LR = which stereo channel (left, right, or both) to be adjusted
+dB or - dB = set to “+” to increase the output level (gain);
set to “-” to decrease the output level (attenuate)
00dB = set the numeric value for dBs of gain (+) or attenuation (-).
The range is -95dB to +31dB.
When configuring Output (OUT):
Lvl = CONSUMER or PROFESSIONAL means the level to be set is for
Consumer or Professional audio equipment
