Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
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 64 enclosure’s AIE Boards are located top and bottom on the rear. Therefore, this
section’s references to left and right AIE slots correspond to the top and bottom AIE slots respectively on the
Enova DGX 64.
AIE Board in Left AIE 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.
AIE Board in Left AIE Slot – Insert Function
Inserted audio is received separately from PC source, embedded onto the HDMI signal, and routed from standard input
through standard output(s) to destination(s) as an HDMI signal with embedded audio.
AIE Board in Right AIE Slot – Insert Function
Inserted audio from auxiliary audio system replaces embedded audio on HDMI signal and is sent to the destination
device.
