If I remove the 75ft shielded coaxial RCA cable it goes away. I have moved my sub cable so that it is not near any of my speaker wires and I still get the hum. I have also tried plugging the sub into the same outlet as my receiver and I still get the hum.
My house is over 150 years old so it does not have grounds even though the outlets except plugs with a ground.
I checked the internet for the suggestions that I tried above. One suggestion that I have not done is try a
sub isolation filter that blue jeans cable sells for $50.00. The RCA is plugged into one end and another RCA on the other end that goes into the sub.
Any suggestions will be appreciated.
Thanks in advance
