For those that have a 350v3 and an SPL meter, can you put the dial on 60dB selection and place your mic about an inch from the sub grill cover, I'm getting 60dB's with nothing playing.
This is the buzzing I'm hearing, maybe my ears are sensitive, not sure. Sounds like the buzz you hear from a transformer station.
Not sure if you still care, but my 350 also has a 60dB hum with nothing playing. It's on its own outlet on the front wall, Rx is on the back wall.
You're ears are definitely more sensitive than mine; I had to put my ear an inch away to hear it.
