Testing/Checking The Insert/Extract Functionality; Aie Board Troubleshooting - AMX Enova DGX 8 Instruction Manual

Testing/Checking the Insert/Extract Functionality

Insertion – If the DIP switch setting results in being inserted onto the corresponding video input or output signal,
execute a test switch using the video signal. If you need test switch details, see page 51.
Extraction – If the DIP switch setting results in audio being extracted from a video input or output signal, check
the auxiliary or supplemental audio equipment involved to be sure the audio signal is present where expected.
If the system does not handle the audio in the expected manner, see "AIE Board Troubleshooting" on page 108.

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).
