The lack of ground for the output side was the issue. Grounded that lug and the channels are now separate. I’ll bring t in to work tomorrow and take a reading of the voltage at the input jack. To do that would I be able to plug in a 3.5mm cable to the mic input jack and take the reading from either channel to ground?
My next step is to make holes in either side of a plastic housing I purchased, align the jacks with the holes and fill with hot melt glue.
Tip, from someone well versed in the use of hot melt glue.
You can glue in a few places only, to secure components inside the case, then cover with tape or cardboard.If you ever need to fix gear later on, it is great to have access.
If you don't want access, epoxy can be used. That is what Chris used I think. Two part epoxy.
Please post pics of finished product
