I was putting my system back together again and have decided to take advantage of the zone 2 and it's amp along with connecting a pair of speakers to the presence jacks on the receiver. I got no sound after configuring the remote to operate zone 2. Then I read that only analog can be sent to these speakers so I connected the dvd/cd player's audio out to the receiver analog audio in and I keep tripping the protection circuitry!! If I disconnect the RCA plugs from the receiver's analog in's then no tripping but certainly no sound?? Any ideas out there on what's happening?
