> Are you guys using "proper powering"?
Mine is green, always has been.
Jbell and I both have green powering. Both using mp6 with latest firmware and channel linking. I was running my ak 40's, john his mk41's both on the same stand with a vark bar.
Anyway here's more info. I too originally thought it was phasing b/c they had the big ass fan cranked and the stand was swaying some! That said we both always use dpa screens there and I've taped in the same room with the same big ass fan for 13 years without issues. And there are some spots that are just unnatural sounding dips and burst of gain on both sources. It almost sounds like an auto gain feature kicking in or something. As with yours it happens to both channels. Perhaps if there was slight phasing the channel linking feature "messed up" for lack of a better term. I'm just guessing!
I have listened to all of mine and also have John's untracked source. I can confirm the issue on his source as well but I haven't listened to the whole thing. There are spots on mine where it appears to happen on his as well but not as drastic. There are spots on mine in the right channel and on his it's the left. On my source the majority of it is during crowd noise and stage banter but there are a few spots in the music where it can be heard.
This is only my second outing with the deck. I taped Holly Bowling a few weeks ago on firmware 1.20 with channel linking and had zero issues. Taped npr in my office yesterday for 45 minutes without issues but I know that wasn't a great test!
Here are samples. All are banter and crowd noise and can be heard best on headphones though you should hear it without.

This is the same spot showing both mine and Johns. I was convinced that the channels swapped but I guess it just effected his different as a few seconds later I can confirm the channels match in both sources. His is audible there as well but not as bad.

Here's another random screen shot with a huge drop for a split second.
