Hi out there,
Looking for some troubleshooting help.
I have a Yamaha Rx-1400, with my fronts pre-outed via a couple of monoblocks. Ihave a CD, DVD, sat receiver, and VCR all hooked up as well as a TV.
When I turn on the yammy, whether or not the monos are powered on, there is a fairly thoaty 'whomp' coming through the woofers of both left and right speakers. If I go from mute to -79 db, or back again, the same sounds happens, as when I power off. there is no other humming or hissing, just these whomps when powering on or off. Now if I switch to CD mode and play a CD, it sounds fine.
Any ideas? I've had the system since September with no problems.
Thanks for anyone's help,
chris
