Enova DGX Audio Insert/Extract Boards

Applicability Notice
This chapter pertains to the following Enova DGX Audio Insert/Extract Board (referred to here as the AIE Board) which supports
analog stereo audio
FG1058-705 Audio Insert/Extract Board

FIG. 91
AIE Boards (shown with a variety of video boards in Enova DGX 3200)
The Enova DGX Audio Insert/Extract Board works in conjunction with HDMI, 4K HDMI, DVI, DXLink Twisted Pair, DXLink Twisted Pair
4K, and DXLink Fiber Input or Output Boards. The AIE Board can be installed in any of the expansion board slots on the rear of the
Enova DGX enclosure. The AIE Board can provide audio insertion and/or extraction functionality for either the input or output
boards. The board's DIP switches must be set per the individual system's requirements. The configuration process requires
removing the board from the enclosure and setting its DIP switches (for details, see page 157). By default, the AIE Board is set with
the extract/insert function enabled. In addition, the connectors default to "extract" audio.
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 expansion slot can be configured by setting the DIP switches to insert or

extract audio (default = "Enable/Extract").
If an AIE connector is set to "Disable," then it must also be set to "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 Enova DGX 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 Enova DGX Switcher.
Left expansion board slot (Enova DGX 800/1600/3200) and top expansion board slots (Enova DGX 6400) – 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 expansion board slot (Enova DGX 800/1600/3200) and bottom expansion board slots (Enova DGX 6400) –

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.

* For example, when AIE Input 1 in the left expansion board 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.
IMPORTANT: 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 the HDMI as embedded audio (insert function) or are 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.
CAUTION: Audio Switching Boards, Dante Audio Switching Boards, and Audio Insert/Extract Boards are not compatible. Do not
install mixed types of expansion boards in the same enclosure. If two types of boards are present, the audio subsystem is disabled.
Enova DGX Model Specific AIE Notes
Enova DGX 800 only – Depending on location, AIE Board connectors 1-8 correspond to standard input or output

connectors 1-8. Connectors 9-16 are inoperable.
Enova DGX 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 6400 only – Numbering overlays are provided for AIE Boards to simplify wiring (see page 159). In the Enova

DGX 6400, AIE Boards in the top portion of the enclosure work with input boards that are also located in the top portion of
the enclosure. AIE Boards in the bottom portion of the enclosure work with output boards that are also located in the
bottom portion of the enclosure.
