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*
* AIE Board FG1058-705 is compatible with the Enova DGX 8/16/32/64, replacing AIE Board FG1058-700 (discontinued) which was
compatible with the Enova DGX 8/16/32 only.
The Enova DGX Audio Insert/Extract Board works in conjunction with HDMI, DVI, DXLink Twisted Pair, and DXLink
Fiber Input or Output Boards. The AIE Board can be installed in any of the AIE 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 123). 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 AIE 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 AIE slot (Enova DGX 8/16/32) and top AIE slots (Enova DGX 64) – 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 (Enova DGX 8/16/32) and bottom AIE slots (Enova DGX 64) – 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 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.
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.
