Denon AVR-3803 Problem (1 Viewer)

[Keith Arment]

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!!!

I would make sure that there are no bare speaker wires touching each other, or the back of the rcvr. Other wise are the speakers at least 6 ohm impedence or higher.

I had a similar problem with my Denon 2803. It turned out to be a nail in the speaker cable that would cause excess current and hence the shutdown on volume peaks.

For some reason your Denon is sensing abnormally high current and is shutting down. Could be a shorted wire, or a speaker of low impedance drawing too much current at certain frequencies and volume levels.

in addition to checking everything everyone suggested, make certain you don't have any blown drivers. a blown tweeter can make the receiver do this, too.

What speakers are you using? I’m going to hazard a guess that they have a 4-ohm rating. Most receivers these days don’t take well to those.

Also check ventilation. If you've got components stacked on top of it or it's in a confined place with now air circulation it can get hot and shut down.

Thanx to everyone that has replied thus far!

I hope it isn't my speakers...but, I can't find the Ohm's in the specs. They are:

B&W DM603S3 (2)
B&W LCR600S3 Center
B&W DS6S3 (4)
B&W ASW650 Sub

There is a Denon Super Service Center nearby, so I think I'll drop it over there for an 'in warranty' service checkup.

Is there a way to test out the speaker wire for nail damage as one person mentioned?? Since, as you can imagine, it ain't easily accessible!!

 

[mackie]

If you have some spare wire or buy some inexpensive stuff you can run different wire to the speakers and see if that makes a difference. It'll be messy while you test it, but it shouldn't set you back too much. Don't get anything expensive.

It may be obvious, but check that all the wires are hooked with the same polarity to each speaker.

I'm going to say the receiver probably isn't the problem, it is a wiring or speaker problem, possibly a setup problem. Do you have the speakers set to small?

One way to check the wiring and speakers is to disconnect all of them and try each one, one at a time. If it does it on a specific channel, then swap a different speaker in there. If it still does it with a different speaker, it is the wiring.
