QUICK START GUIDE
Enova DGX Audio Insert /Extract Board
Overview
Enova DGX AIE Board (FG1058-705*) works in conjunction with HDMI, DVI, DXLink
Twisted Pair, and DXLink Fiber I/O Boards in DGX 8/16/32/64 and DGX 100 Series
Switchers. AIE Boards can be installed in expansion slots on rear of enclosure and can
provide audio insertion and/or extraction functionality for either input or output
boards. DIP switches must be set per individual system requirements. For complete
documentation, see the switcher’s manual at www.amx.com.
* FG1058-705 is compatible with Enova DGX 8/16/32/64 and 100 Series, replacing AIE
Board FG1058-700 (compatible with Enova DGX 8/16/32 only), now discontinued.
IMPORTANT: Setting the DIP switches is the only way to configure the AIE Board’s insert/
extract functionality. Therefore, if the switches require setting (which involves removal of
the board from the enclosure), it needs to be done during system setup.
AIE Board Information – Must Know for System Setup
• Individual connectors on an AIE Board in either AIE slot can be configured by
• setting the DIP switches to insert or extract audio (default = enable / extract).**
• When audio is “extracted” from an HDMI signal, the audio signal is not only sent
to separate audio equipment but also remains intact as embedded audio on the
HDMI signal which is handled by the switcher.
• When audio is “inserted” onto an HDMI signal, the audio signal replaces the
embedded audio on the HDMI signal which is handled by the switcher.
• Left AIE slot – AIE Board connectors correspond numerically to the standard
input connectors. The audio signal on AIE Input 1 is either inserted or extracted
onto/from standard Input 1 (2 works with 2, 3 works with 3, etc.).***
• Right AIE slot – AIE Board connectors correspond numerically to the standard
output connectors. The audio signal on AIE Output 1 is either inserted or
extracted onto/from standard Output 1 (2 works with 2, 3 works with 3, etc.).
• The audio is always inserted or extracted as analog stereo audio at line level.
• Insert/extract settings provide unity gain to and from the digital domain.
• AIE Boards are not compatible with Audio Switching Boards; furthermore, if both
types are installed in the same enclosure, neither will work unless one type is
removed.
** Changing the default configuration requires removing the board from the enclosure,
setting its DIP switches, and reinstalling the board.
*** For example, when AIE Input 1 in the left AIE slot is set to insert and then you route
HDMI Input 1, the audio signal for AIE Input 1 is embedded on the HDMI signal.
NOTE: The AIE Boards do not form an independent switching matrix. When an AIE Board
is used on the input side, audio signals cannot be controlled separately, but must either
switch with HDMI as embedded audio (insert function) or be sent to supplemental audio
equipment (extract function). When an AIE Board is used on the output side, audio
signals have already been switched as embedded audio with HDMI and can be either
replaced or extracted, depending on which function is set.
Important Product Specific Notes
•
Enova DGX 8/800 only
– Connectors 9-16 are inoperable.
•
Enova DGX 32/3200 only
– AIE Boards will not work in conjunction with standard
input and output connectors 17-32, which are on the boards in the last four input
and last four output board slots. Remaining standard board slots should be
reserved for input/output boards without audio insert/extract needs.
•
Enova DGX 64/6400 only
– Special overlays for renumbering AIE connectors ship
with systems containing AIE Boards. To apply overlays, refer to instructions
provided with kit.
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: Only 2 channel L-PCM audio is supported from the AIE extraction port.
Multi-channel (>2 channel) L-PCM formats will pass incomplete audio if extracted. All
other audio formats will be muted at the extraction port.
AIE Board in Left AIE Slot
Extracted audio remains intact but is also sent for further distribution.
Inserted audio is embedded on HDMI signal and routed to destination(s).
AIE Board in Right AIE Slot
Inserted audio replaces embedded audio on HDMI signal.
Embedded audio remains intact but is also sent to supplemental audio equipment.
AIE Boards in Both AIE Slots
On left – extracted audio remains intact but is also sent for further distribution.
On right – inserted audio replaces embedded audio on HDMI signal.
Setting AIE Connectors to Insert or Extract Audio
Setting AIE functionality to insert or extract audio requires removing the AIE Board,
setting the DIP switches, and reinstalling the board.
IMPORTANT: If the factory default of “enable/extract” meets all of the system’s needs,
removing the board is not necessary. If an AIE connector is set to “Disable,” it must also
be set to “Extract.”
Removing the AIE Board
CAUTION: The AIE Board has an EMI (Electromagnetic Interference) gasket along one
edge of the face plate. Handle the boards carefully to avoid dislodging or damaging the
gasket on the board being handled and the gasket on the adjacent board or blank plate.
To remove the AIE Board:
1.
Power down the enclosure. (AIE Boards are not hot-swappable.)
2.
Enova DGX 32/3200 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.

IMPORTANT: AIE Boards are shipped with all of their insert/extract DIP switches enabled and set to extract audio.
If the system’s audio configuration requires audio insertion on one or more connectors, the board(s) will need to be
removed from the enclosure and DIP switches set to insert audio before the board(s) are returned to the enclosure.
