Greetings from A#1 HT Novice in CNY! I am having a problem with my newly self-installed Denon AVR-3803. In a nutshell, when the volume exceeds a certain point or is accentuated with a movie (and this varies at -15 to -5 Db) the rcvr shuts itself down...and it's not like I'm blastin away (my wife doesn't allow that!). I have read the manual inside and out and tried multiple configurations, but nothing has remedied the problem. Since this is the one-stop site for everything HT, I'd like to ask if anyone has an opinion on what might be causing this? I know there may be additional information about my environment that may be required to determine the issue, so please ask away. THANK YOU all in advance for any suggestions!! Have a GREAT day!!!
