Hello tls
thanks for the help.
It is in my home. I have cabinet that Holds all the media (receiver,tv box, Xbox, and more).
The outside speakers are bluetooth controlled.
I can't change the power supply position.
I did more tests and it is ground problem.
The yamaha receiver and the subwoofer don't have ground pin in there soket, so I connected ground pin to the reciver metal cover.
It helped to the hum noise but didn't make him to go away..
