Question about Denon AVR-2807 Receiver

1 Answer

I think my amp is broken

I have a denon surround 8 channel amp, i think its the one listed. The model number has 2800 in it. Anyway, the 4 main channels make any speaker attached to it sound completely blown, and it's not the speakers. The centre and rear speaker channels still play fine. Apart from it sounding blown, there is barely any sound.

Any ideas

Denon 1312 makes clicking sound will not turn on


If the front display does not light up at all when the press the power button, it is usually either the main power fuse or the power transformer. If the fuse is blowing, that usually means a short in the amp section.

I have done some research about my denon arv-1601 reciever, narrowed it down to a ressistor problem, it turns on for 4 seconds and turns off and goes into standby mode. Any Suggestions?


Usually it is bad power supply problem or bad channel problem. Look for any burned parts, it helps you locate the problem. Burnt resistors in one channel- you need to replace output transistors (better to replace all transistors in that channel) and bunch other surrounding parts. If you do not see any burned parts, check all voltages coming from power supply +15 -15 +5 etc then check dc at every channel output (not at speaker terminals but at control pins on the amp/main pcb), should be +-10mV

I have just bought a new bose 901 speaker system which included equalizer. I am not sure how to connect the equalizer to my receiver Denon 3808. I need help.


http://products.bose.com/pdf/customer_service/owners/901_guide.pdf

Be advised, this speaker system requires its own dedicated two channels of signal preamplification and power amplification and the required Active EQ is not to be used in the signal path of anything else. I have them as my Main Left and Right Speakers in a 7.1 set-up, but I'm using a 5-channel external Carver Power Amp to drive them, a sSb and the Rear Surrounds. The Active EQ is between the Receiver's Main L&R Preamp Outputs and the two Carver Amp channels that drive the 901's. Don't think you can just add the 901's into your living room and enjoy multichannel sound. Search around fixya, I have written extensively on this subject.

I just received a Denon AVR-4308ci receiver. I have two passive subs in my system. The receiver only has one powered output. Since I am not using the surround back speaker outputs can I use these for the...


Sure, if you want to hear Surround Back program material coming from the subs without midrange or tweeters. (Sarcastic) Of course, the LFE program material will still be going into a black hole somewhere.

Run the subs in series with each other -
Sub Amp negative to 1st speaker negative;
1st speaker positive to 2nd speaker negative;
2nd speaker positive to amp positive.

Run the speaker level adjustments routine and enjoy.

Just for giggles, try what you were thinking about. You won't hear much from the sub(s) unless you programmed the Surround Back channel as full-range and then have something like the Apollo 13 launch for program material. Normal audio won't send much low-frequency material to those channels. The optimal place for subs is on the LFE or sub channel.

No surround back channel - damage during transport


I think your receiver has cracked main (amplifier) board close to surround back channel terminals. Need to take apart the receiver remove the board, inspect it and resolder cracked traces. Unfortunately it is not so easy to remove that board and probably you need to bring it to a repair shop.

Best amplifier for bose 901 VI speakers


By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

No surround sound from my Denon 3805


well as long as all signals are routed through the Denon your on the right track, now what else you have to do is connect all devices to the reciever do not loop one device through another. Also you have to try the different surround fields to hear the one you like the best for music I use 5Ch stereo for movies the surround field varies based on the type of movie

Back speakers with av denon 1908


Plug your rear 5.1 speakers into the surround speaker connections. Be sure to use the AVR 1908 set up menu to set rear speakers (not an amp assign). Hope this helps.

Denon AVR-2307 Protection Circuit Activated permenantly


The speakers are 4 ohm speakers, a guy on another chat site sent me a link to the impedance curves http://www.audioholics.com/reviews/s...t-v2-fs/page-4

He agreed to that there was a mismatch as the unit has plenty of fresh air around it, plus all the speaker cables have been tested and installed correctly.

So, off to the store where I got it from tomorrow.

I need to set up 4 pair of speakers, two zones. all ceiling mounted.


Okay! all ceiling mounted speakers. I don't know about 4 pair of speakers.Here is the load down:
First pair of ceiling speakers would be left and right front from speaker A or Main output behind your receiver.
Second ONE,but a pair would be connect to the center channel output as your center speaker.
Another pair would be connect to the surround sound left and right(NOT surround BACK left/right.)
Now,you have 5 channel setup at this point,you still need to purchase a power subwoofer to the SUB PRE-OUTPUT behind your Denon receiver.

For Zone two,you would need to connect your other pair of speakers to surround BACK left and right output.
Go to your Denon MENU button,depending on which model you have,some of them will have an on-screen display feature(you would need to have a composite video cable connect from the video output behind your receiver to the TV video input in order to use the on screen menu.)If not,you would have to it view on the front panel of the A/V receiver.
You need to read the detail on how to setup the video and audio as well as distance and DB for the receiver through the menu button.
I will be frank with you,if you are an amateur,Denon is NOT easy to be setup on the first time.
