Configuration
Ch 1/2 Control and Status
The
CH 1/2 CONTROL AND STATUS
display (
) provides
status reporting and controls for setting the following parameters on Ch
1/Ch 2 output of the 2020ADC module:
•
Output mode, and
•
Gain adjustment to set maximum signal level input to 0 dBFS digital
output.
Set the
CH1/2 MODE
for the desired output of the module from the thirteen
selections listed below in
. After making the selection, click the
APPLY
button to activate it.
The following status items will be reported in this display:
•
CH 1 L CH AND CH 2 R CH > -20 DBFS
indicates whether the Ch 1 (left) and
Ch 2 (right) digital output levels are greater than -20 dBFS (
TRUE
) or
less than -20 dBFS (
FALSE
),
•
CH 1 L CH AND CH 2 R CH > -0.5 DBFS CLIP
indicates whether the digital
output clipping levels for each channel are greater than
-0.5 dBFS (
TRUE
) or less than -0.5 dBFS (
FALSE
), and
•
REFERENCE SIGNAL
indicates whether the module is
LOCKED
(valid
AES reference signal is present and module is locked to it) or
UNLOCKED
(module does not detect a valid AES reference signal).
