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.

Not quite sure where you are in your investigation.

If your system is connected to cable tv I will share I had a pretty obvious hum/buzz. 

What solved my problem entirely was connecting the following Jensen VRD-1FF IsoMax CATV Digital RF Isolator between my xfinity coax and the xfinity cable box needed to run my TV.

Note that the coax from outside is first split and one leg goes to the TV and the other to my modem/router.  This was only needed on the coax leg going to the xfinity cable box.
