AIE Audio Insert/Extract Boards

Enova Digital Media Switchers - Hardware Reference Manual
AIE Board in Right Expansion Board Slot - Extract Function
Audio is extracted by the AIE Board on the output side for use in supplemental audio equipment as well as remaining
intact as HDMI with embedded audio from the output to the destination device (FIG. 87):
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 (FIG. 88):
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.
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
Setting AIE functionality to insert or extract audio requires removing the AIE Board, setting the DIP switches, and reinstalling
the board.
If the factory default of enable/extract meets all of the system’s needs, this process is not necessary.
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.
