AVR3312CI Center Speaker Drop-Out Issue
I've been running into an issue lately with my AVR-3312CI. I bought it new about a year and a half ago, and have been loving it...up until about 2 months ago.
I have it set up so Zone 1 runs 5.1 in the theater area and Zone 2 drives a pair of speakers out on my porch.
About 2 months ago, the center speaker has been dropping out intermittently. It is accompanied by the clicking of a relay. The 3312ci display does NOT change: it keeps the 5 speaker input and the 5 speaker output display. This only happens with 5 speaker input, NEVER with stereo input which is converted to 5.1. Nor does it always happen. When it does, the relay(s) click about a bunch. Sometimes just turning it off and on seems to work. Sometimes not. Changing inputs sometimes gets the center channel back. Again, the center channel drops out with 5.1 input.
I -think- this is a receiver issue, not a speaker issue. (FWIW, the speaker has not been moved or replaced for a year and half, a little shifting to check the connection is all.
I've reset the microprocessor, but the problem, intermittently, is still there.
Additionally, it seems to be running a bit warmer than before.
I've emailed Denon support and gotten no reply other than a list of links to articles like "How to connect your speakers." Really?
So...is it time to RMA?
Has anyone else run into a similar issue?
