Enova DGX Audio Insert/Extract Boards
120
Instruction Manual – Enova DGX 8/16/32/64 Digital Media Switchers
Enova DGX Model Specific AIE Notes
Enova DGX 8 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 32 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 only
– Numbering overlays are provided for AIE Boards to simplify wiring (see page 125).
In the Enova DGX 64, 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.
AMX reserves the right to modify its products and their specifications without notice.
