Noise coming from subwoofers and centre channel

Hi,

I have a noise/hum in my subwoofers and only one speaker, the center.

When listening music only, the noise is really low but when watching a movie with the projector and madvr processor, the noise become louder.

Someone have an idea, something common?

Thanks in advance for any help.

Turn that off etc. etc, (narrow down on what’s creating the noise by process of elimination) If the sound shows up only on the center channel and subs (not the fronts??), i am also inclined to believe that it may be something with the av processor/receiver. Check all cable connections, check for sht failing cables, make sure everything’s plugged in where it’s supposed to be, etc.

It was indeed a nightmare looking behind multiple racks with heaps of sht, gear and cables everywhere.
