I have repaired many of these Denon receivers over the last few years.

Since the headphones work, that means if you dis-connect the speakers it will turn on and not go into protect (when power cuts off a few seconds after turning the unit on).

The most likely problem is a bad speaker. to find out which speaker is causing the problem, do this.

Start out with just one speaker connected and then turn on the unit. If it turns on and plays music, you know that speaker is good.
Now turn the unit off again and add another speaker and keep the first speaker connected. Once again, if the unit plays, that speaker is also good.

Keep doing this same procedure one speaker at a time. As soon as you connect a speaker and then try to turn on the unit and it goes into protect, the speaker you just connected is bad.

To confirm that this speaker is the bad speaker, dis-connect all speakers and only plug the suspected bad speaker into a speaker jack that worked with one of the other speakers.
If the unit still goes into protect you know then that you have found the bad speaker.

If the unit still goes into protect, that speaker is bad and you will need to take it in for repair or replace it.
make sure you use 8 ohm speakers. if i remember correctly these Denons can use 6 ohm speakers, but those are harder to find and most home speakers are 8 ohms.

If the unit does not go into protect and that suspected bad speaker plays in one of the other speaker jacks, what you really have is a bad channel in the amplifier, the channel that the suspected bad speaker was previously connected to.

If you find out you have a bad channel, you will need to take it in to an repair center. Preferably an authorized Denon service center. There are not very many of those around. I work at the only authorized Denon service center in the entire state of Michigan.

If I can be of more assistance, don't hesitate to ask. And a good rating is always appreciated. :)

SOURCE: wiring speakers to denon avr 3802

Those are not compatible speakers for this unit. The Denon receiver does not have any speaker outputs for that type of speaker.

The Denon speaker outputs are full range outputs. Your speakers are not designed for that, they need an amplifier that has seperate outputs for the highs and lows.

By using these speakers you will probably damage them and they will not sound very good as well. The tweeters will end up fried and it is also likely that if one of the speakers goes bad, it will blow one of the channels in the amplifier.

If you really want to do it anyways, and don't say I didn't warn you, you could connect them using the "A" and "B" speaker outputs. Connect the woofers on one set, lets say "A", and the tweeters on the other, lets say "B". Right channel "A" would be the woofer and right channel "B" would be the tweeter for one speaker.

When listening to the unit you would need to engage both the "A" and "B" speaker to hear anything from both speakers, there are buttons on the display for the speakers marked "A" and "B" and in the display you would see little icons that light up when the speakers are engaged.

I can not stress it to you enough that this is not a good idea to use these speakers with this type of receiver. Do this at your own risk and be prepared to pay about $150 to $200 for the repair bill after the amp blows a channel.

Check that your speaker cables are not touching each other at the amp end and also at the speakers as this will cause the amp to shut down.

hope this helps.

SOURCE: AM,NEED REMOTE CONTROLL DENON AVR-3802 HOW I,BUY?

I had the same problem. Unfortunately Denon no longer mfgs. the remote for this receiver,
their solution is to offer a remote for a "similar" model. Problem is it doesn't work on all the
functions for the AVR-3802. My solution was to purchase an aftermarket universal remote
(Logitec Harmony 550 in my case}. The cost was a little less (approx. $90) vs. the price
quoted by Denon (somewhere around $120), and it works on all the functions.

I don't know if a budget priced remote (All-in-one, etc.) would be able to do th same.
There are several different programmable remotes on the market that should do the trick,
Logitec just happens to be one of them.

Good Luck

That's why they print manuals. What sound went out? TV or Denon speakers? We're not clairvoyant enough to back into the button sequence you MAY have initiated. I'd start with basic test tones.

It's the amp tripping to protect itself.
