Audio Routing with GPI Control Example
Figure 3-7 shows an example of using the 9921-FS Routing controls, upmix/
loudness processing controls, and GPI controls to:
•
Route an embedded network main 5.1-channel feed through the card
(Emb Ch 1 thru Ch 6), but conditionally provide upmixing if the
5.1-channel complement is stereo audio only. Also, apply loudness
processing before re-embedding it into the output SDI path.
•
Provide stereo loudness processing for a network SAP stereo feed,
and re-embed this pair into its original location (Emb Ch 7, 8).
•
Provide the ability to replace the network main audio with that from a
Local Insertion AES pair (AES pair 1) using a preset invoked by a
ground closure on
GPI 1
.
•
Provide the ability to replace the both the network main audio and
SAP audio with that from an EAS receiver on AES pair 2 using a
preset invoked by a ground closure on
GPI 2
.
A
thru
E
on sheets 2 through 4 show the setups using the DashBoard™ tabs to
accomplish the setup shown in sheet 1. Sheet 5 shows the use of presets to
define the setups, and provide for GPI automated triggering of these setups.
Note that the source, internal bus, and destination correlations shown here are
only examples; any source can route to any destination.
