Hi Guys, So it appears I over looked something simple. After swapping the tops the problem didn't follow. As I was diagnosing things I hard wired around all of the out board gear between the console and the amps to make sure that I didn't have a piece of bad gear. I have a DBX compressor in in the inserts for the main channels L&R. I forgot that, so as I was eliminating things, it was always in the mix. It is the culprit. Thanks for all of your help. Below are some photos of how I have them installed Blessings,
Nick
