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.
