Hi, complete n00b here (and first post) , sorry if this is in the wrong forum.
Just hooked up a Yamaha RX-V373 receiver to some in-ceiling polks & center. Everything seems to be going swimmingly when I turn on the receiver , view movies / cable / usb / music.
When I turn the receiver off, it emits a loud and quick shriek/screech (turning it off via the remote). Does anyone have any suggestions what the cause could be?
Thanks for your help, in advance, and again sorry if this is not the correct forum.
