Enova DGX Audio Insert/Extract Board
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:
FG1058-700 Audio Insert/Extract Board
The Enova DGX Audio Insert/Extract Board works in conjunction with HDMI, DVI, and DXLink Input
or Output Boards. AIE Boards can be installed in either of the AIE slots on the rear of the Enova DGX
enclosure. The AIE Board can provide audio insertion and/or extraction functionality on either the input
or output side. 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 105). 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”).
Unused AIE connectors must be set to “Disable/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 – 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.
* 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.
