AIE Board Troubleshooting
If the audio is not present or is not at the expected destination, you may need to re-wire to a
different connector.
To verify, check the connector numbers on the AIE Boards. The AIE connector numbers
correspond directly to the numbers for the standard input or output connectors that they
insert audio into or extract audio from. AIE 1 works with standard Input 1, AIE 2 works
with standard Input 2, etc.
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 – Remember that the AIE Boards will not work with connectors
17-32, which are on the input and output boards in the last four input and last four output
board slots.
Verify that the AIE Board is seated correctly by repeating the reinstallation procedure and then
test/check the insert/extract functionality again.
If extracted audio buzzes when connected to a balanced audio input device, wire the AIE
connector as follows: AIE L to device L+; AIE R to device R+; AIE ground to device R-; and
a jumper from device R- to device L- (see FIG. 64 below).
Options for Wiring AIE to Balanced Audio Input Device
Standard Wiring
The wiring in FIG. 63 is the standard way to wire an AIE connector to a balanced audio input device.
If Necessary – Wiring to Eliminate Buzzing
The wiring in FIG. 64 can be used if the extracted audio buzzes when connected to a balanced audio
input device.
