To clarify, the noise is audible in my QSC K12’s when the APC UPS is in line with my Qu16, with power from my American Audio power distro. Take the APC UPS out of the power chain: dead silence in the mains. I would not care if there was noise when running on battery, as at this point there are other problems to deal with.

I’ll certainly give another APC UPS a try, as if they can be used are a very economical solution. I have a couple more of them at home, so as soon as I get everything set up again I’ll check it out & report back.
