Question about Denon Audio Players & Recorders

Open Question

I have a denon AVR-591 Receiver which keeps shutting off. I have checked the speaker wire connections and can confirm these are all fine. Sometimes it works and sometimes it dosen't, but most recently it hasn't worked for over 4 weeks - tried again 2 days ago and it worked - tried again tonight and not working again. Any ideas.....or have I been duped into buying the 'floor Model'?

It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.

When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.

If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.

If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.

On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".

If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.

I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.

If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.

If I can be of any further help, let me know.

SOURCE: Denon AVR 2106 clicking noise

I like when a user is observant and curious. That will help immensely in resolving this problem.

What source(s) are always involved with the problem?

You imply it is observable with output video to the TV - "only when there is movement on my tv screen and it stops in still screen". That sounds like a digital pathway problem of some sort as any data errors would eventually escalate to something audible or visible to you once the hardware and correction algorhythms are exhausted. The clicking inside the receiver could be its efforts to resynchronize with a bad data stream. Hence, I'd like you to isolate the ins and outs that fail all the time and find the probable single source of the problem.

Try this: put a digital source on and select/deselect it for listening or viewing. Does it make the click in that brief time it's 'thinking' before you hear the source? That would be the 'normal' sound. My Pioneer does it once per source switch. Repeated clicking would mean it's struggling.

I'm betting you have an optical or hdmi cable that's flaky or not in tight and straight. Or, if only one extternal source is involved we follow that back.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

Denon avr 1507.recently replaced with new set of speakers.sound got dropped.keeping full volume only i can able to hear something.


Hello,

Are you using normal impedance speakers? If it worked correctly before, and even better if you can connect the old speakers back to verify the receiver works correctly, would give you a clue.
If the new speakers are a difficult load (below 4 ohms) it may overload the amplifier and it will shutdown to protect itself. You need to provide more info to access correctly.

Removing all speakers and using a headset will also validate the operation of the receiver.

Good luck.

I was watching a movie on my denon avr-3808ci and all of a sudden it made a loud sound and it shut off. The power button was flashing red and wne I tried to turn it on, the power button would turn green...


probably one of your speakers has blown.. disconnect them all. turn the reciever on.
if this works turn it off connect one speaker and turn it on.. keep going until it goes red...
when you find the speaker discennect all the other speakers keep this one connected and confirm that it is this speaker giving issues.

if the amp doesn't come on with all speakers disconnected, remove the visual outs and start it with nothing connected. isolate the issue if this works. otherwise it might be your amp.

Denon AVR 1804


You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.

Hi My denon avr 2600 keeps clips when turn on


Check the polarity (+/-) of the speaker wires. A typical receiver will try to cut the power to the speaker if it's feeding it too much power or too little power to preserve the speaker and/or receiver. That may be the clipping you're hearing. If the wires are reversed, this can cause the same thing.

I have a Denon AVR-488..Can you help?


Sounds like you may be clipping your speakers. Check all speaker connections and make sure they are not touching, at all. If you are not using speaker ends and are simply twisting the wire and connecting to the speakers, just one strand touching the other post will cause this. Good Luck

Denon avr-2106 getting hot shutting down


Normally when this happens it is because the impedence load is too small. This unit requires 8 Ohm speakers. If you connect 4 Ohm speakers, it will work, but work harder and generate excessive heat. If the heat is too much, the unit will enter protect mode and shut down. Once it cools off, it will work again. In your case, if the speakers are the correct impedence, check for crossed wires. If that is the problem, running the unit at higher volume levels should cause it to shutdown sooner.

Keep us posted,
Dan
