Same thing murph, I had a gold splitter adapter at the receiver. One of my 350's was on its own leg. I had it calibrated to 75dB's, but as soon as I plugged in the other line which included the 600, it dropped about 6-7 dB's.

Maybe Alan will see this thread and consult with Tom C. to give us a better understanding than Brent telling me the 600 has more output....
