These extra inputs may be making the Denon hiccup while it processes the signal? I never tried it without the alalog ins. The one advantage with analog ins simultaneously is that when you switch to menu funtion, it displays the menu over active picture(although downrezzed to analog and I guess re digitized to pass thru HDMI. With HDMI in and out only, it displays the menu over a black screen.
Ps. Despite my harping on the BluRay DVD fiasco, I succumbed to the walmart secret sale this morning and bought a Toshiba HDA2 for a price that once I get the 5 rebate movies will be free for all practical purposes. With this as my second HDMI input to the Denon, I'll be able to compare and see if any sync issues happen. I'm thinking its the analog to digital changes.

Don't want to open up a debate on which one is best or anything, just looking for some past experience. Thanks.

Are you using it as 5.1 or 7.1, and have you done the Audessy setup from at least 6 positions? I went from 3 to 6 and it made a big difference."warmer"
From old debates, it seems the concensus is that Denon has a more neutral sound(which can easily be manipulated any way you want via all kinds of menu options) and Yamaha and Pioneer have a "warmer" sound. Bottom line-I wouldn't sweat it, but that's what we do!

Hey guys I'm looking at buying one of these today, but I've got a couple questions before I do. My system is as follows -

Panasonic TH-50PHD7UY 50" Plasma (720p/1080i only through Component - HDMI board only support 576p )
Panasonic S-97S DVD (720p/1080i upconversion via HDMI only)
TiVo HD (set to fixed 1080i)


Now my questions -
1. Would I have any issues connecting the TiVo HD and Panny DVD to the 2808 with HDMI and then outputting from the 2808 to the TV with Component?
2. Should I just ditch the HDMI altogether and use component & optical connections for everything? (This would limit my current DVD to 480i/480p)
3. A little off-topic - In the event that I upgrade my DVD to an HD or Blu-Ray, would I get the same features and quality using component/optical as I would using HDMI (TrueHD, etc)?

Sorry I'm still a newb when it comes to some of the areas. Thanks!

1. For HDMI in there is only HDMI out.
2. You can mix and match. For your DVD I think you can have HDMI directly from DVD to TV (to get your 720p/1080i upconversion) and also have Optical-digital audio go to the 2808CI (to get best audio). Depends on flexibility of your DVD player. Then stick with all HDMI for the TiVo.
3. There are things that work via HDMI that you won't get via component. I won't try to list them all because I am fuzzy on it myself. Some of this is the ability of components to cooperate with each other (like recognizing each others' capabilities and making sure formats/decoders, etc. match up). There are some higher-end video capabilities (Deep Color, xvYCC color) and perhaps also audio capabilities that may not come through component or optical cables (not sure of this).

Can't do this becuase my TV only has one HDMI input. I'm currently using a Monoprice HDMI switcher. Also wouldn't I be losing quality using the HDMI since the HDMI board in my tv only supports 576p?

Cool thanks.

I've always wondered why my pic quality seemed to look worse after switching from component to HDMI....

I have a pioneer plasma 6070 and have just purchased the Oppo 981hd (Its on its way) I have a Starchoice HD sat. rec. Is there any advantage for me to have the 2808 as compared to the 2308? The Oppo has to go HDMI thru the Denon, as it only has HDMI output. I am a oldie, but a newb to this newfangled contraptions!!

Hi, newb here.

Could someone give me step by step instructions on how to set my 2808 to pass thru only of all video signals (DVD, Cable box).

Thank you!

Went to audition one of these today at my local Magnolia. They just happened to be rewiring the entire rack.

I currently have a Yamaha 661 (90Wx7). Would anyone be able to tell me how much difference in sound quality to expect between the two? Also how well does this unit handle LFE?
My system is Def Tech. BP7004 mains, CLR 2300, pro monitor 1000s. Mirage S10 sub.

Thanks!

Just spent 4-5 hours reading threads on the Denon AVR 2808Ci, 3808Ci, Onkyo TX-SR705, and 805 and want to thank all the members for the invalueable info.

As far as audio, will they both put out audio via HDMI to the TV or will I need to run another digital signal? Which will better perform in HT surround sound and music playing from a HTPC?

Thanks Tony. Went back and A/B'd the Yamaha v1800 and the Denon won. It's not "bright".....but rather clean and clear. The clarity is great. Going to stop sweating it now!!!

Good deal. I've had quite a few things from Nakamichi to Marantz to Pioneer Elite and Counterpoint separates. I've gravitated back to Denon, it's hard to beat for the money.

Thanks! So it uses one of the new 8-channel BB DAC's. Interesting. I wonder how it compares to the 987 (uses Analog Devices DACs) I have now. Any thoughts?

What did you think of the Onkyo 805?

I'm running the Denon essentially as a pre/pro in my system; I do use the internal amp for Zone 2, but I use external amplification for F/R and C/Surround. I scored my 987 for around $400, and I like it, but I've been wondering if I'd like the 805's supposedly superior DAC performance.

The sound of the 987 (in 2-channel, fed pre-out to an external amp) is quite nice: sweetly extended, very detailed, and lend a nice feeling of air to the performance. On the negative side, the sound tends towards the thin side of the spectrum more than I'd ideally like.

I'm seriously considering the 2808CI, but I have a basic electronics question:

What will happen if I hook up the 2808CI to my existing 4 ohm speakers? (The manual says they should be 6 ohms or higher -- 8 ohms if you use both A and B speakers.) Will I just get higher volume at a given setting? Do I run the risk of blowing out my speakers? Could it cause a problem for the receiver itself?

I owned a 805, now own Denon 3808, I would love to downgrade to 2808, but 4 HDMIs stop me! even I do not need all advanced networking etc.

I could have bought 805 from CC for $650 to downgrade to 3 HDMI, but I do not have heart to save myseld $600 after owning and returning 805. If budget allows stick with denon.

Is it possible to connect an external amp to the AVR-2808CI, such as a Rotel RB-1080. I'd only use the Denon for processing, no amplification. If this is possible, how so? Thanks in advance.

The 2808CI is accepting an HDMI signal (from a DVD player), optical audio input (from the HDTV built-in ATSC tuner) and one HDMI output to my TV.

The menu is not displayed unless the HDMI I/P scaler is on. The menu is not overlayed with the scaler turned on. Is there a configuration that will display the menu (or atleast the volume)? Would a composite connection to my TV solve the problem?

Hey- Newb here. I have had the 2808CI for a few months and over the past few weeks- it has been randomly (i.e. once every few days) turning off and the power indicator flashes red. I know it could be overheating or wires touching one another. The unit is in a cupboard; but pretty well ventilated. Nothing is moving- so I doubt it is the wires. Any other suggestions/ recommendations. Thanks

This sounds like an overheating problem to me.

First be sure you don't have 4ohm speakers. Must be at least 6ohm. If this is not the problem I can believe that being in a cabinet (even if well-ventilated -- which can be a matter of opinion) it might overheat with either prolonged use or use at high volume (or with 4ohm speakers). You should try a fan. The best I have found is the following:

http://www.stayonline.com/detail.aspx?ID=8663

Be sure to get the one linked above and NOT the following:

http://www.stayonline.com/detail.aspx?ID=8665

The first is a complete set-up: fan and power supply. The second is an extension unit that needs to be plugged into the power supply provided by the first. They daisy-chain together.

These fans are very quiet and turn on and off based on temperature. They have very low air movement but just enough to do the job and remain quiet.

If you want, you can buy a set of three to daisy-chain:

I'm a current owner of a denon 3208 receiver. I'm debating as to the need to upgrade to the 2808.
My needs are to get the most from my new toshiba A35 hd dvd player on my panasonic plasma.
How important is "THX" certification lower price receivers have it, but not denon prods.
Any comments welcomed. john

hi guys nice reciever

Can someone please help me understand ....

here are specs taken from denon uk re 2808 ...... http://www.denon.co.uk/site/popup/in...&Pid=351&vPidN[0]=338


Scaler 480p bzw. 576p / 720p / 1080i
(for analogue Video-Signals > HDMI-output)


HDMI Video Conversion
Video, S-Video ->HDMI 480i/576i, 480p/576p, 720p, 1080i,p
Component 480i/576i ->HDMI 480i/576i, 480p/576p, 720p, 1080i,p
Component 480p/576p ->HDMI 480p/576p, 720p, 1080i,p
Component 720p ->HDMI 720p, 1080p
Component 1080i -> HDMI 1080i, 1080p


Ok so it scales analogue signals to only 1080i & spits it out the HDMI out(eg to display).....
but then sais it takes a vid,s-vid, component input & scales it to HDMI 1080p ....huh isnt component analogue aswell? confused?
So if i send a 1080i component signal from my HD set top box will it scale it to 1080p & send out HDMI to monitor?

Any recommendations? (I know this isn't the yammy forum.) Also, I had his extension down as x8632. Perhaps I'm dis-lexic. Anyways, just ask for him by name.

I'm pretty much in the same boat...I'll be interested to hear if you've got any luck. Either way I've got a phone call to make Monday morning.

1080p scaling via component?

I'm feeding my Denon 2808 via component from my sat box (1080i) and then to my tv. Where, if it exists, would I find the settings to scale and output from the 2808 to TV at 1080p? I thought this was a basic setting toggle but can't seem to find that menu. The HDMI set up is straight forward but I'm a couple of weeks from receipt of my HDMI cables.

Yes, the 2808CI has preamp outs so you can connect it to another power amp.

Will I just get higher volume at a given setting? Do I run the risk of blowing out my speakers? Could it cause a problem for the receiver itself?


At 4 ohms, in order to output the same wattage the amp will need to drive more current.
Power=current x voltage
But Ohm's law: Voltage = impedance x current

Power = Impedance x Current^2

The sound you will get depends on sensitivity. It is expressed in dB/Watt

If you want say 60 watt through your speaker (assuming that the speakers have the same sensitivity, they will have the same volume)
with 8ohm speakers you will need 2.74 Amps per speaker
with 4ohm you will need 3.87 Amps.

This means that the amp will have to drive more current and will heat more to the point of potentially shut down...

FYI,

My wife called to see if the deal was still available....it was and she ordered it for xmas for me They have a 3 yr warranty for a good price too
