You would need a newer HDMI 1.4 AVR to pass a full 1080p 3D video.

Hey all - after finally getting my setup complete the with Audyssey - I have noticed that when I listen to DTS surround sources - the speech/talking from the center channel is QUITE low...

In multiple different movies - when there is quiet talking - I can barely hear it - literally straining. But then a loud scene comes on and shakes the room.

I have compensated by raising the center channel level to a very high level - which is not right for other sources.

What is the solution here? It seems like it would be very unintuitive to have to change channel volume for each source I watch.... and if this is the answer - can I save a different template for each style? (e.g. watching DTS auto changes the channel levels to one I select)

I bought a used 2808 and I have a serious sound quality problem.
I got used to the idea of having this AVR, so I want to try everything to fix this problem myself, if possible.

I currently connected two Dali Zensor 1 speakers as Front A L/R. These were tested and sounded great with a Rotel amplifier.
I tried to feed the 2808 with different kind of sources (analog stereo input on RCA, 16/44 PCM stereo and 24/192 LPCM as well as DTS-HD, TrueHD bitstreams) but the sound is always awful.
There is virtually zero bass and the whole sound is just bad.

I tried to do factory resets. I even tried to update the firmware (wasn't that easy to find a serial port these days) and reset again.
I tried to run the auto setup and I also tried to set up the (very simple 2.0) speaker configuration manually. (The auto setup result is even worse, but it is always awful.)
I tried to use the Pure Direct mode with both analog and digital stereo inputs. No luck.

Any more ideas before I try to get a full refund and look for something else?

Those are fairly small bookshelf speakers so although one wouldn't expect a whole lot of bass output, the overall audio quailty should still be quite good, especially after running Audyssey. Based on your troubleshooting thus far, I'd return it. frown.gif

This issue is more likely movie specific so adjust the center channel on the fly as needed. Note that this issue is more easily resolved in the newer models that feature both Audyssey Dyn EQ and Dyn Volume.

I've lost sound on both the front right & left speakers. In 5CH STEREO mode I'm getting sound on center and both rear speakers only. Similar results when performing a speaker test. Any ideas on how to debug or fix or am I looking at a repair job. Thanks.

More than likely someone pressed the SPEAKER button on either the front panel or the remote and changed the setting from "A" to "B". Check the right side of your display and if it reads "B", then press the SPEAKER button (under the front panel flap) until it says "A" again.

I posted this in the Speakers forum, but haven't received a response, so I'll try here. I've got a 2808CI, using Infinity RS6000s as my fronts and components from an Infinity TSS1200 (Sub, surrounds and Center Channel) to round out the system. This system is used a lot for TV/TV-movie viewing. It is typically in Dolby Digital surround mode (DirecTV receiver HDMI input to the receiver, then out to the TV). In movies with a lot of action/sounds, the voices are typically hidden well behind the other sounds. I've tried everything I can think of to compensate for this on the Center Channel. Any setting suggestions that I may have missed? Should I consider a better center channel speaker? If so, any suggestions? Thanks.

Not familiar with your speakers but if TV/movie watching makes up the most of your listening then the center speaker should be at least the same quality (or better) as the FL/FR speakers as 85% of the dialog comes from the center speaker. Ensure prior to running Audyssey you have the center speaker pulled out (if inside a cabinet) and aimed up towards the ear height of your main listening position (ie. mic #1 position). Are you using a camera tripod or mic boom stand to support the Audyssey mic as suggested in the Owner's manual? Is anything blocking the line of sight from the center speaker to your ears (eg. coffee table)? Have you tried bumping up the center channel level 4-5 db as doing so will not negatively impact the Audyssey filters? Also, to better understand Audyssey, suggest you review the Audyssey 101/FAQ Guide linked in my sig.

Thanks for the suggestions. I suspect my problem is the quality of the center channel speaker. The RS6000s (my fronts) are from Infinity's Reference Series of the 1980s. They were/are outstanding speakers. I'll review my current set up based on your suggestions. Thanks again.

First try unplugging the power cord for about 10 minutes and give it a try again. If no joy, then reset the microprocessor (p. 50 OM).

Perhaps you can explain your setup in more detail and answer the following questions? ... do you have a 2.1, 3.1 or 5.1 setup? .... what does the front panel display when playing a video? what video source is being used and have you tried both HDMI inputs? .... does the video and audio work when the source is connected directly to the TV? ..... when you rerun AUTO SETUP, do you hear the test tones from every speaker and the sub?

Also note that if you no longer have the Owner's manual, you can download it from Denon's website ....

I want to buy oppo BDP-105,and would like to know if my Denon AVR-2808 can do analog pass thru,
I'm planning on using analogue output's for audio and HDMI for video.
So will that work considering the oppo 105 has a better DAC and will enhance the SQ or I won't gain nothing and won't notice any improvement in the SQ,and would be better of going for the 103 and connecting it via HDMI?

i'll try...5.1 speaker setup...going hdmi out from the denon into the t.v...a blu-ray player and game console going into the denon via hdmi...when i set the t.v on the appropriate input..then turn the denon to the appropriate input...the t.v recognizes no video and the speakers no audio...but the denon display still recognizes the speakers..can still switch through different speaker settings...and yes..both the bluray player and playstation both work when hooked straight into the t.v...

I'm not sure what you mean by "analog pass thru" but the 2808CI has a set of multichannel analog inputs that are compatible with the Oppo's multich output. These multich inputs bypass all digital processing and go straight to the amps, thus avoiding the Denon's DAC's, so if that's what you mean by "pass thru" then yes, it has it.

You can combine these multich inputs for audio with the video of any other input, by switching the input mode to EXT IN.

The thing to note however is that, when bypassing digital processing, the receiver basically turns into an amplifier only. The player serves as the "processor", providing all audio decoding, bass management, etc. That means you lose the benefit of the receiver's digital processing, especially the Audyssey room correction.

So essentially it's a tradeoff where the plus side is potentially slightly better DAC's on the player side, but the downside is the loss of room EQ which improves your acoustical response. By and large, the latter is much more important than the former, which is why the 103 is the better buy for modern HDMI equipped digital receivers. The 105 is really intended for the "audiophile" buyer who has an older, non HDMI amp or a high end analog setup.

I don't have an amp,I'm planning on connecting the 105 to the AVR via analog,if I won't gain an excellent SQ then I'm better of getting a 103 and using HDMI.
Please advise.

Is there any thing I can hook up to my AVR to improve the SQ via analog like preamp/pros,power amp or amp?
I'll be hones I don't even know what they are or do I just see alot using them with their AVR.

You're much better served just connecting to the AVR via HDMI and don't worry about an external amp.

The 105 player has a better DAC than the one on my Denon AVR,so if I connected the 105 via analogue it won't enhance the sound quality,so HDMI is the best option.
But what if bought a power AMP and connected it to the AVR via analogue and the player with the speakers will be connected it to the AVR via analogue for sound and HDMI for video.
Will that work and enhance the SQ or I'm better of using HDMI?

the question about an external amplifier is totally unrelated to your question about HDMI vs. analog. They are separate issues.

The only reason to get an external amplifier is because you need more power. It will only enhance SQ if you are actually running out of power with your current setup (using the amps in the receiver). If you find you can turn it up as loud as you care to without it sounding harsh or distorted, than an external amplifier will not enhance SQ.

Like I already explained above, the question about analog vs. HDMI sound quality is basically a battle between two factors: with HDMI, you get the benefit of Audyssey MultEQ XT room correction, and with the analog path you will get any incremental benefit from the Oppo's DAC's. It is unlikely that the difference in the DAC quality is more important than the room correction of MultEQ XT, unless you have a really good acoustic room.

Try listening to some content and turn Audyssey on/off and hear for yourself what it's doing.

your receiver already IS a preamp/processor. That's what a receiver is, by definition: a pre/pro + amplifiers in one box.

Connect with HDMI, yes, that's what we've been telling you wink.gif

If you want to enhance SQ, look at (1) better speakers and (2) improving your room acoustics. Futzing with the electronics will have a minimal impact relative to those two. The primary driver of sound quality is your SPEAKERS and your ROOM.

holy crap!!! i fixed it!!!...opened it up an upon inspection noticed a white "male to female connector " in the northeast corner that connected one circuit board? to another had became unconnected...reconnected it and it freakin worked...i cant believe i actually fixed it...and after i already ordered an avr-1912 that i really oculdnt afford...can anyone tell me how the 1912 compares to the 2808 in terms of sound quality?

Congrats! Nice work! smile.gif

The 1912 is a lower end receiver and thus will not have the build quality or amp power of the 2808. It has a lesser version of Audyssey (basic MultEQ instead of XT). That said, it does have Dynamic EQ + Volume plus a lot of newer features (networking, on-screen GUI overlay, etc). If you do most of your listening at moderate volumes the addition of Dyn EQ/Vol will probably actually yield better sound quality, but at high volumes it will be no contest, the 2808 is better.
