Enova Digital Media Switchers - Hardware Reference Manual
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.

Extracted audio remains intact from standard input to standard output but is also sent on to an auxiliary audio system for
further distribution (FIG. 84):

Inserted audio from auxiliary audio system replaces embedded audio on HDMI signal and is sent to the destination device
