MX3282A Aux Outputs

[dawgpilot]

I was testing my MX3282A board and found that the AUX 1 send no longer puts out signal across all the channels. While testing, I found that through the talkback mic I do get sound through the AUX 1 output.

Since schematics are impossible to get, can someone help me determine what is in the circuit between the channel aux and where the talkback mic enters the stream.

Thanks for the help.

In our PM, I suggested checking the ribbon cables that connect the boards together.

The talk back coming out the send tells us the send circuit itself is working.
