NOTE: Only 2 channel L-PCM audio is supported from the AIE extraction port. Multi-channel (>2 channel) L-PCM formats will pass
incomplete audio if extracted (only 2 of the multiple channels will be extracted). All other audio formats will be muted at the
extraction port.
System Examples
The examples below show some uses for the insertion/extraction functionality on the AIE Board. Individual connectors on an AIE
Board can be set to insert or extract audio onto/from their numerically corresponding standard inputs/outputs.
NOTE: The Enova DGX 6400 enclosure's AIE Boards are located top and bottom on the rear. Therefore, this section's references to left
and right expansion board slots correspond to the top and bottom expansion board slots respectively on the Enova DGX 6400.
AIE Board in Left Expansion Board Slot – Extract Function
Extracted audio remains intact from standard input to standard output but is also sent on to an auxiliary audio system for further
distribution.
