How to Specify Extended Pass-Through Audio Sources for a Mono Partition
1 Ensure that you have not selected a ‘Synchronous Stereo Audio’ partition.
2 Go to the ‘Pass-Thru Shuffle Audio Source’ table. Take note of its contents. The table has 16
entries, each corresponding to an audio output channel (of any output of any disembedder/
embedder card in the router). The channels are identified.
3 Choose a channel. Enter one of the audio input ports of the hybrid router in the ‘Source’ field
for that channel. We recommend that you specify one of the unused audio ports of the
router’s disembedder cards (or MADI cards). Otherwise, if you specify a normal port, that
port cannot be used for any real input.
 Always choose an unused audio port number that is greater than the number of video
input ports of the router. Unused port number between 1152 and 2304 will work well for
any NV8500 router.
The port must be in the range of the ‘Synchronous Audio’ inputs. The field must not be
blank.
Leave the ‘Source’ field blank if you do not want to use pass-through audio for that channel.
4 Repeat step 3 for any other audio channels for which you want pass-through audio.
5 Perform other changes in the ‘Router Level’ page as required and click the ‘Update Control
Card’ button at the bottom of the page.
How to Specify Extended Pass-Through Audio Sources for a Stereo Partition
1 Select a ‘Synchronous Stereo Audio’ partition.
2 Go to the ‘Pass-Thru Shuffle Audio Source’ table. Make a written note of its contents. The
table has 8 entries, on the left side of the table, each corresponding to a (stereo) pair of audio
output channels (of any output of any disembedder/embedder card in the router). The
channel pairs are identified.
3 Choose a channel pair. Enter one of the audio input ports of the hybrid router in the ‘Source’
field for that channel. The field actually accepts values in the range [0–65,535] but only valid
audio port numbers will work properly. We recommend that you specify one of the unused
audio ports of the router’s disembedder cards (or MADI cards). Otherwise, if you specify a
normal port, that port cannot be used for any real input.
 Always choose an unused audio port number that is greater than the number of video
input ports of the router. Unused port number between 1152 and 2304 will work well for
any NV8500 router.
Leave the ‘Source’ field blank if you do not want to use pass-through audio for that channel.
4 Repeat step 3 for any other channel pairs for which you want pass-through audio.
5 Perform other changes in the ‘Router Level’ page as required and click the ‘Update Control
Card’ button at the bottom of the page.
