Two steps which might help diagnose the problem.
Disconnect the internet/tv cable from the cable box or/and modem.
Try a cheater plug.
In my situation both helped so I purchased a Jensen VRD-1FF IsoMax Digital RF Isolator. Problem was solved.
Speaker Hum
|
I just moved into a new (to me, actually built in the mid 60s) house where no matter which outlet I use I get an audible hum through the speakers when the volume of the integrated amp is pushed past 50%. Would any power conditioners improve or eliminate this severe of a problem? Any thoughts would be appreciated! |
