Enova DGX Audio Insert/Extract Board

Instruction Manual – Enova DGX 8/16/32 Digital Media Switchers
Note: 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.
Important: 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.
Note: 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.
Enova DGX Audio Insert/Extract Board – Specifications
Applies to Audio Insert/Extract Board FG1058-700.
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.
