I did a two day music festival over the weekend with two iPads on wireless and one docked. It was the first time in a long while I have had an iPad docked and it would stutter and then resync on a regular basis. Wi-Fi and Bluetooth were off, 100% battery (it was docked). It didn't cause any major issues, but it was interesting to see and experience what so many others have been over the last few years.
The gig last weekend was the worst, it was at an outdoor event, on a generator. Every couple minutes the docked iPad would resync.... I'm guessing it was a combination of noisy power, oddball ground, and 100 degree heat.
The event we did this past weekend was nice and cool, with clean power, and I had less problems. It's 100% power related in my opinion. Ground potential on phantom power maybe? I have not tried with phantom power off because we have a couple things that would need power injectors to function.
Then again, I did a gig where my daughter had her keyboard, guitar and mic plugged in, and it resync'd a lot there. Still, I am sure phantom power was turned on, even if not used.
I'll try to find a way to test that idea soon.
