Question about Onkyo TX-SR601 Receiver
I am using a self powered subwoofer and I can hear a 60 cycle hum when I put my finger on the end of the RCA plug at the amplifier. I do have it turned on and the crossover is set to 100 cycles. What did I miss??? Is there another switch in the software that I need to switch on the subwoofer output besides the "yes" in the program? Any suggestions would be appreciated. Wyman
No that is normal if it does it wile using and ur not touching it make sure power plug isnt touching the coard. and some anps do that when they r turned up to loud. or worn input or output plug

TIPDon't use a normal cable or satellite program for this; you're about to disconnect the cable that provides the audio and video for your cable/satellite feed.
WARNINGOddly enough, this solution (surge protection) can sometimes increase the humming.
WARNINGIt is unsafe to use a two-prong to three-prong "cheater" plug on the subwoofer power cord to solve the hum problem. Even if the subwoofer came with a cheater plug in the box, it's REALLY not safe to do. Don't do it.
