| Hi Coyoteous, You have a point! When I have a problem like this I isolate the unit and connect it to my A/D and Monitor-Amp turn the gain of my Monitor-amp up to hear if the problem is comming out of the unit. It works oké for me.
Then I test it with lower to higher levels at the pre-amp inputs and hear what is happening there. But when it is interference or a *groundloop you can hear it with the first test. Only a noisy track
proofs nothing. When this is not working out I go to a friend who can measure the unit for me.
Cheers David
