Enova DGX Audio Insert/Extract Boards
157
Hardware Reference Manual – Enova DGX 100 Series Digital Media Switchers
AIE Boards in Both Expansion Board Slots – Insert and Extract Functions
On left – embedded audio is extracted from standard input side and is sent on for audio processing.
On right – inserted audio replaces embedded audio on HDMI signal and is sent to the destination device.
NOTE: When audio is routed through a separate Audio Matrix Switcher, the audio can be inserted back into the original system on
multiple audio insert/extract connectors.
IMPORTANT: When audio is “extracted” from an HDMI signal, the audio also remains intact as embedded audio on the HDMI signal.
Setting Audio Connectors to Insert or Extract
IMPORTANT: If the factory default of enable/extract meets all of the system’s needs, this process is not necessary.
Setting AIE functionality to insert or extract audio requires removing the AIE Board, setting the DIP switches, and reinstalling the
board.
IMPORTANT: Setting the DIP switches is the only mechanism for configuring the AIE Board’s insert/extract functionality. Therefore,
setting the switches (which requires removal of the board from the enclosure) needs to be done at the time of installation setup.
Removing an AIE Board
CAUTION: AIE Boards have an EMI (Electromagnetic Interference) gasket along one edge of the faceplate. Handle boards carefully
to avoid dislodging or damaging the gasket on the board being handled and the gasket on the adjacent board or blank plate.
NOTE: If an AIE connector is set to “Disable,” then it must also be set to “Extract.”
To remove an AIE Board:
1. Power down the enclosure (the AIE board is not hot-swappable).
2. Enova DGX 3200 only – Loosen the captive screw on each end of the numbering plate above the boards, and set the plate
aside.
3. Remove the pan head screw that holds the AIE Board in place.
