Configuration
Audio Control and Status Web Page
The Audio Control and Status web page ( Figure 10 on page 25 ) provides
controls for setting the following audio parameters on the 8920ADC
module:
• Operational (output) mode, and
• Fine adjustment of left and right output channel levels.
The following audio status items are reported on this web page:
• Left and Right Ch > -20 dBFS – indicates whether the left and right
channel digital output levels are greater than -20 dBFS (True) or less
than -20 dBFS (False).
• Left and Right Ch > -0.5 dBFS Clip – indicates whether the digital
output clipping levels are greater than -0.5 dBFS (True) or less than -0.5
dBFS (False).
• Reference Signal – indicates whether the module is Locked (valid AES in
reference signal is present and module is locked to it) or
Unlocked
(module does not detect a valid AES in reference signal).
Use the following controls to set the parameters for the 8920ADC:
•
Operational Modes
– Set the operational mode pulldown for the desired
output of the module from the thirteen selections listed below in
Table 7 and shown in the web page in Figure 10 on page 25 . After
making the selection, select the
Apply
button to activate it.
Table 7. Audio Output Configuration Modes
Mode Name Mode Description
Default Factory default with no phase inversion, channel swapping or summing.
L/R Swap Swaps left and right channel outputs.
L/R Invert Both left and right channel outputs phase inverted.
L Invert Left channel output phase inverted.
R Invert Right channel output phase inverted.
R Mono (R to L/R) Right channel to both channel outputs.
L Mono (L to L/R) Left channel to both channel outputs.
L plus R to L/R Left plus right to both channel outputs.
L minus R to L/R Left minus right to both channel outputs
L plus R, L minus R Left plus right to left channel output and left minus right to right channel output.
(L plus R) Inv to L/R Left plus right to both channel outputs with both channel outputs phase inverted.
AES Silence AES silence on both left and right channel outputs.
1K@ -20dBFS Tone to both channel outputs.
