3.4.9 The Audio Processing panel
The audio program inputs to the IRD-3101 are placed into the four AES channels embedded in the IRD-3101 ASI
output.
Decode mode:
If the input audio programs have passed through the
decoder:
the decoded outputs from Audio 1 (5.1 program which
is decoded to six discrete channels), are grouped into
three pairs of two channels (Left/Right; Center/LFE,
and Ls/Rs) and each pair is assigned to one AES.
The decoded outputs from Audio 2 (stereo program)
are grouped as a pair (Left/Right) which is assigned to
one AES
Bypass Mode:
If the decoder has been bypassed (Decoder Operation
pulldown set to
Pass-Through
in the Audio Configuration
panel) for either of the programs:
The non-decoded audio (AC3) will be inserted into
one of the output AES channels
Only the AC3 element is available in this case; the
decoded program element pairs shown in the figure
do not exist
The default assignment is as shown in figure 3.18.
Click the radio buttons to change the assignment
A program element pair or AC3 program can be
assigned to more than one AES if desired.
3.4.10 The Reference panel
NOTE: The OPT-FS option must be purchased in order to
enable this panel. Otherwise the reference is always taken
from the input signal.
The IRD-3101 output signals should always be genlocked to
some reference source. The genlock source is selected in
the Reference control panel. Use the radio buttons in the
Reference Source area to select from the following options:
•
Auto – this mode selects the first source detected in this
order of priority:
o
External
o
URS
o
Selected Input signal
•
External – selects the signal connected to the rear-panel
REF IN connector
•
525 from URS (Universal Reference Signal) – selects
the internal reference (525) from the backplane
