Enova Digital Media Switchers - Hardware Reference Manual
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 181). 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.
Enova DGX Audio Insert/Extract Boards - Specifications
Applies to Audio Insert/Extract Board FG1058-705
.
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 (only 2 of the multiple channels will be extracted). All other audio formats will be
muted at the extraction port.
