Question about Denon AVR-1906 Receiver

Open Question

I have a Denon AVR-1906 amp. connected to a 5.1 KEF speaker system. The problem is that the output is very low on treble. I've tried connecting other speakers, and can confirm it's not a probl

I bought the system over 5 years ago, thus it's out of guarantee.

    Edit: Just to clarify, the unit doesn't go into protected mode. In fact the output seems fine, except for the fact that the treble appears to be non-existent and the sound in general lacks dynamism and punch.
    I have my satellite system connected, as well my Denon DVD player (hdmi), WD TV Live media player (hdmi) and a dvd rewriter.

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. :)

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck

If your tv is putting out mono you will only get the center and sub speakers. This can be because the tv is only mono, or the output is set to mono in a menu of the tv. If you have cable or sat run the digital audio out to you receiver; it usually sound better that way anyhow. Set your receiver to Dolby mode for best sound.

If DIGITAL sign on the display blink, it mean the DSP board is defective. probably the DSP itself

Well,i can tell you are not very focus,cause you posted Denon AVR-2807 with Bose AC 15 problem,but under your details,you put down AVR-5807!
First of all,it is so unfortunate that you are NOT able to gain and experience to true ability in sound for this wonderful receiver when you are using a dual tweeters speakers and expect to have good sound separation as a TWO WAY speakers(a tweeter and a midrange-for true high frequency and mid frequency sound separation.)
Secondly,you have defeated the audio configuration of the Denon AVR-2807,since all your speakers are control BY the Bose subwoofer.
Now,i could show you a way to hook this up,and it doesn't matter how you connect them, they are the "bicycle tires" installed with a "Porche"engine if you know what i mean.
If you want a good recommendation for your "beast",i will more than happy to show you the way!
Cheers,

Power supply problem


Could be a blown amp channel. Once the output transistors go, it doesn't matter if you disconnect the speakers or not, the damage is done. Could also be a voltage regulator, but not as likely.

I have a Denon AVR 1905 stereo receiver. It turns itself off after a couple of seconds. I've already tried "reset."


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

One of my Q 75's is just not performing properly,all the drivers make sound,just not enough of it,I've swapped both speakers from right to left so it's not wiring or the reciever.No buzzing or...


Try reversing the POLARITY of the wires on the speaker that is playing at a low volume (swap wires connected to the + and - terminals of the speakers). This would put the speaker back in phase if it were reverse connected, and provide the expected volume level again.

Good luck!

Denon AVF988 to power amp to whole house speakers


jbell302, Check both remote spkers for operation from the A spks output if good, switch B remote spks to A main connect & main A spks to the B remote connection on the Denon spks outputs . Most amp sources do not like different ohm spks types & different cable or spks A-B. lenghts, because this makes up to resistances problems, making the amp to work harder & understanding what is going on. THE AMPS PROTECTION CIRCUIT IS AT ALERT & TRIES TO BALANCE THE RESISTANCE VOLUME. Best move is to try use the same spks. lenght & a higher qauge wire; 12.14.18qa. to better balance the output volume! All matching spks. pairs would help alot as well!

Hi,
I found your question while searching the web for the same problem myself.
After finding a denon instruction manual online, I found out that the on screen display isn't output through the component video conection. Instead, it is only sent through the s-video or the yellow phono jack style video connections.

I connected it up this way and have seen the on screen display. But I was a little disappointed with it. It is just white text on a black background which shows the same info that you see on the unit's front panel!

Hope this helps

AVR-1603 - no Sound exept over Headphones is a weak signal


First check the outputs at the output fets/transistors for any DC voltage. Reference your voltmeter to the speaker - terminal. If there is ANY DC offset, the amp is shutting down the outputs to protect your speakers from DC. Is the power supply + and - 47 volts? If only one supply is there That is your problem because the supplies should be symmetrical. Also look for any wiring problems from the amp to your speakers... any shorts? Try disconnecting all your speakers to totally eliminate any speaker problem and see if the relays still click. You should hear only ONE click when you first turn the amp on (delay of about 2-5 seconds). If they keep clicking the amp outputs are next. Also, is there any indication on the front panel of what is failing?
