Losing treble at higher volume

Hi I have a denon AVR-3802 amp with DB Dynamics home theatre speaker package (I think the speakers are built in Austraila) when playing a audio cd through my dvd player (as I dont own a CD player)in stereo at 1/2 to 3/4 volume the sound drops noticably in the high range treble as if someone has put a pillow to the speakers. I upgraded my amp recently from a AVC-3800 to the AVR-3802 and still experiencing this pain can you help please and give me some sound advise would be appreciated. Regards

There are two things. First check the sound settings of the DVD player. It might be putting out a lower quality sound on the CD side of things.
Secondly try to determine if the speaker tweeters are working. Connect the speakers if you can to another sound source. If the speakers are good and the settings fine. Then you have a fault in the amp unit.

SOURCE: Stereo speaker suddenly stopped giving sound

You will need to take the speaker apart and with an ohm meter or continuity tester, measure the resistance of the speaker right at the speaker to see if the speaker is open. if it is you have no choice then to replace the speaker. If the speaker measures a low resistance, measure the wires froom the speaker to the output wires or terminals. Some speaker manufacturers install small fuses inside their speakers. Good Luck

SOURCE: popping during action scenes at moderate volume

the woofer is being overdriven and the voice coil is hitting the magnet structure.eventually it will damage the coil end and it will scrape in the gap.

My denon avr 3802 reads no back speakers and there is no power to them. any ideas

You must TELL it it has back speakers and assign the amplifiers for them. It's in the manual. Page 10-12.

I bought a Denon AVR 791 receiver two months ago, work great, sound great with my Definitive Technology Speakers but 3 days ago while I was watching a movie on my PS3 the receiver turned off on the higher...

Clearly, it thinks you're overdriving it.

Blinking Power Indicator every 2 seconds means the internal temperature is high. (Page 76 of the manual)

Every half-second - speaker impedance too low.

Consider the load presented by the speakers and what their minimum impedance might be.

Check for loose speaker wires.

Denon AVR 1910 Volume Level

My Pioneer VSX-36TX (circa 2002) does the same thing. Modern AVR's count up from minus something to 0db and go just a few db higher into 'plus' territory. It seems arbitrary but that's how it is.

Ask yourself this: who ever really turned the volume knob up to maximum on any amp on purpose, and had speakers survive it? In other words, why have all that capacity on a potentiometer if you never use it?

Little known fact: With that in mind, Bose Corp actually designed a product that intentionally used the full physical travel of a volume control - the Bose Acoustic Wave Music System.

Want to put set of outside polk speakers to Denon avr 2807

Do you have outputs for both A and B speakers? If so you can easily hook the outside speakers to the B outputs.

Denon AVR-3802 Problem

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.

Denon AVR 883 Audio glitch

More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.

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.

Is it possible to to have a home theatre with Denon AVR 3600

one option that may yield results, since the bose connection to equalizer is presently not possible is to set the speaker out put on the denon for 'small' on all but the front speakers.
and then set the delay for all speakers based on the distance to the amp.
this should result in better audio that that with the bose eq.
will work on the issue of using the eq. with the denon if you like. but, you will likely not improve on the sound with the denon set up correctly.
good luck
