Hum/Buz fro JC1


Does any JC1'owners have this problem? Any recommendation and input to fix this problem is appreciated.

Thanks.

is your cable tv near the system? if yes, it may be that you have a ground loop. try disconnecting the coax cable from the cable box and then turn on your system to see if the hum is gone.
houstonreef, while I do not have the JC1, I did own the A21 and also had issues with the humm/buzzz. I found that the amp was very sensitive to how well the interconnect was seated. Only a slight mis-seat would cause a buzzz. Try wiggling the interconnect around and make sure it is pushed all the way in. I hope this helps.
