The "Official" Denon AVR-2808CI Owners Thread - Page 110

Update,
Best Buy does not sell internal amp fuses at least that is what the worker said. He did direct me to an electronics supply. I had to go with a 8 or 15 amp or wait till the middle of next week for the 10amp I needed. Went with the 8amp and am up and running. Will really have to watch the volume I guess with the lower amp fuse.
We noticed my repair man had put a 9amp. Maby he did this because the 1st time I had trouble I burnt stuff and the repair was expensive. The electronics store doesn't sell 9amp fuses. Wonder if I should stick with the 8amp? The label on the Denon reads 10amp.
Thank you for the help.

Much cheaper to replace a fuse than have to do repair work. The 8 amp should be fine. Just remember to set the Volume Limit (p. 30) to -20db to be on the safe side.

^^+1

denggenmei8372, JD is not talking about the price of fuses. My first repair cost me around 300$. That was with the factory 10 amp fuse. The last 2 times I simply blew fuses. The 2nd fuse I changed myself and was surprised to find a 9 amp (blown) in a slot labeled 10 amp. (Changes fuses is cheaper)
JD--I had no trouble at -5db as a max volume so I'm probably going to try that. haven't tried -5 with the 8 amp but it worked fine with the 9amp.It was more like +5 for about 3 seconds when I blew the 9 amp.
HAPPY hOLIDAYS!

The safest Volume Limit setting would then be -10db. Suggest you set it at that and then you don't have to worry about ever going above the max again.

I don't mean to sound stupid, I have had Denon AVR's for 10 years. Can someone tell me if the Audessey Calibration Channel Levels should be used for accurate sound, or should I set channel levels with my Radio Shack SPL Meter at 75db. Audessey has the subwoofer at 75db, but the other 6 channels are 2-4db low, and I have been adjusting for that to bring everything up to 75db. Is that correct procedure?

Also, when calibrating my Oppo speaker levels, I set all channel trims for EXT IN to zero, and then I use the DVD included with the Oppo to set channel trims. I am really not sure if this is common practice, or if there is a better way. How are the EXT IN channel trims designed to be used?

Can someone please clear this up for me? I have Denon AVR 2808!

^ Hi, these are not dumb, but indeed highly technical questions. The RS SPL meter is not more accurate than Audyssey, especially for the bass freqs.

Now, lets discuss why you are using Ext In and exactly what Oppo model are you speaking of.

When running Auto Setup, does the volume control setting affect the outcome? 2-4db difference is a lot from Audessey to SPL Meter, subwoofer volume is the same with both, other six channels are way low.

I use EXT IN's with my Oppo 83SE for listening to MCH music. I have room treatments, and don't care for DSP altering of MCH music done by the Denon. I use 2 channel analog on the Denon for all 2 ch music sources. I only use Audessey/HDMI for BluRay movies and DVD movies!

Great, I just got one of those SE models yesterday, wow, just amazing 2 ch DACs! I am very interested in your experience with Denon, Audyssey and Oppo analog and have started a thread which touches on such matters here. I hope you will join us and report on your experiences. I have not played with analog MC yet but I seem to recall there are some quirky issues with LFE levels. I've have been told there is a guide here. The Oppo SE thread would probably also be a good place to post on this.

All settings in the AVR are ignored during autosetup.

I know autosetup does not apply to the EXT IN, been using EXT IN for some time (channel levels on the Denon do affect the EXT IN), I set the ch levels on the Denon to 0 for EXT IN, and then set channel trims in the Oppo 83SE with the Oppo setup disc. I just thought that the autosetup routine set the channel levels to 75db for the Denon, obviously that is not the case. So that must mean that I am correct in setting channel levels to 75db after running Audessey Auto setup?

Can anyone else chime in on this?

I must apologize and correct myself, further searching on the 3808 thread yields this post from batpig which appears to indicate ch levels in the AVR do apply. MC analog is new ground for me so I welcome others' input as well and am interested in your procedures and results.

no, on newer AVR's with Dynamic EQ the auto setup calibrates the reference level so that the speakers play 75dB with the test tones (master volume 0) but on most other receivers (including your 2808) the volumes just come out balanced relatively. So in all likelihood they are NOT going to come out at 75dB when you play the test tone.


not necessarily, the Audyssey mic is still more accurate than your RS SPL meter. So let's say all your volumes are set to 72dB instead of 75dB... you can reset them to 75dB using the RS meter but it is likely that the relative balance is now less accurate. Even if you got them all perfect, the only difference would be that the volume dial is on a different number to achieve the same loudness.


the RS meter is notoriously poor for setting subwoofer volume. In all likelihood, they were balanced before and you now have the subwoofer 2-4dB too low.

if I were you, I would leave the trims where Audyssey set them.


as noted above, channel trims in the AVR are active for the EXT IN inputs but nothing else is. So you can choose to either zero out the trims and set it all up in the Oppo, or use the Denon trims and leave them zeroed out in the Oppo. It doesn't matter which one you use as the end result is the same -- the speakers are all calibrated to the same volume.

^Maybe I have the wrong calibration microphone, there are four different Denon AVR's floating around the family.

Can someone tell me the correct PN for the Denon AVR-2808 microphone number?

Doh!!

Batpig,

I have an Animode 8033 subwoofer equalizer put into my system before the last Audessey Autosetup. REW shows the subwoofer flat, so the test tones should be pretty accurate for the sub. I have not seen the other channels come out that low with Audessey after autosetup. My system just seems to have unbalanced channel levels now. My subwoofer after Autosetup was -4.5, L/RF +1.5. The last time I ran Autosetup the L/RF were +4.5. Isn't +4.5 louder than +1.5, or is the Master Volume coming into play with the test tones?

It is listed on one of the first few pages of your OM, where all the included items and remote(s) are specified. DM-A405

SoundofMind,

The microphone pn is not in the manual, the remote pn's are listed though, page 5! I called Denon support this evening, and they said none of the microphone pn's are in the manuals. I was on hold for 15 minutes and he came back with the pn for AVR-988 which is the same DM-A405. I have too many Denon receivers, they have at least two different models of microphones.

Thank You, Good sound to you!

^ Oh, I thought the mic model # was listed in the OM. I have had a number of different Denon AVRs as well including a 988, which is a really fine unit. I have deleted my old manual so what I did was "search this thread" for "DM-A" and found jd's post on mics which gave the whole #. It is easier now as the mics are the same for all newer models, the DM-A409.

I am still interested in learning more from you about analog and what you end up doing about your levels. I may not end up using much MC analog but will for sure retain 2 ch with HT bypass.

Also, sorry, I was only referring to the mic model # and djwobbrock was asking for part #.

The 2808ci mic model DM-A405 which is listed in the manual on page 23.

The pn should be #3210040006.

The DM-A405 does coming with other Denon AVR units as well.

The DM-A405 is used with the XX08/XX8 models while the newer DM-A409 has been used for all model years since then. And yet another model was used prior to the XX08/XX8 models. As they are calibrated specifically for a particular model/series, it's important to label them for future use as to which of your models they can be used with. Also if a replacement DM-A405 is needed then order from a US source (esp. Denon authorized parts distributor) as the foreign sellers on eBay are apparently selling knock offs.

SoundofMind,
I am giving up on MC analog listening. My room modes are still bad even with all of the bass traps that I added. I have a 15-20db peak(hump) between 20 - 40hz that won't go away, bass traps only work above 100hz, and subwoofer postion is limited to LF/RF corners. I spent two days trying all possible locations for my subwoofer, and the only thing that changed is where the hump moved to.

I was listening the 2ch analog from my Oppo 83se, in Pure Direct mode on the Denon, speakers small, sub on, LFE+Main, crossover 100hz. I thought it sounded pretty good, except low bass levels were too high, the 20-40hz. I purchased an Antimode 8033, and ran some graphs on REW. The sound was awesome, but the low bass was still too high. I did rerun Audessey Autosetup on the Denon 2808, and ran calibration to 75db with my RS SPL meter. After much reading on the Audessey and other forums, I decided to give Audessey another chance for , MCH & 2CH listening. My eyes are now opened, I have been reading too much on how the Oppo 83SE was for 2CH analog listeners only, so I have been trying to setup my listening room without using Audessey settings. Wroooong! I have had Denon receivers for ten years, and I have always used the RS SPL after running setup. Another big mistake. I am now using Audessey for all of my listening, HT, 2CH, MCH, and I am loving it. REW graphs opened my eyes. I did not know that Audessey affects the subwoofer as well as the other seven speakers. The combination of Audessey and the Antimode 8033, has made my bass fantastic, very tight, very pronounced, very dynamic, wow, wow. I did not know what Audessey MultiQ XT really did, and now I am listening to a much improved listening room. The Antimode with the 2808 and Audessey has given me the best sound ever in my room. I am using the Audessey settings from autosetup, even though my RS SPL does not have every channel level at 75db. An unbelievable difference for me. My new Hafler/Musical Concepts modded 2CH amp has a tubey sound to it. My M&K subs sound better than ever, they are vintage subs, and were good producing tight low bass, now with the Audessey/Antimode they are over the top with bass. I now have a fairly flat FR in my room, and with the Antimode set to flat, I have a nice house curve!

Unless you have a near accoustically perfect room, or full room treatments, analog listening can be a challenge to get good results.

I am a new fanboy of Denon Audessey MultiEQ XT and Antimode 8033!

^Wow that is a lot of valuable info, thnx dj. Can I call you dj? It doubtless took many hours over many days to sort all that out and I appreciate your helping to shorten my journey. I was almost ready to order bass traps last week, then I began to hear more and more recommendations about Antimode 8033. I have started a thread here to discuss some of these issues in detail and so I wouldn't end up highjacking threads in my newfound upgrade craze. We'd value your posts there very much.

I also have a very challenging room acoustically, and when I hooked up my first Denon, a 988, the MulTEQXT just knocked my socks off in terms of SQ. I have been a fan ever since, reading these forums and steady picking up tidbits from batpig, jdsmoothie, et al.

Well, the Velo DD10 is in the family room/HT slowly warming up. Dang, it comes with a pretty nice mic.

SoundofMind,

Don't get me wrong, the Bass Traps helped alot! I purchased four 2' X 2' X 6" for each corner near the ceiling, and I built four more myself using Ultra touch. After adding bass traps, even my wife couln't beleive how tight the room was, a loud clap went no where. She even approved of their looks, suede fabric covering in ruby red to match my mahogany veneered speakers. The four I made were large woven baskets filled with Ultratouch and aritificial plants (look great). The finishing touch was the Antimode and really Audessey in the Denon 2808 brought the sound over the top by reducing reflection influences and difraction! With the MultiQ XT and the Antimode, I have what is offered in the Denon 4311 minus the networking. When I decide to go to downloading music, Itunes or flac, I will invest in somthing like the Audiolab 8200 CDQ for PC sound.

Good sound to you!

This is great info and consistent with all I've heard, that it is best to correct the room as practical and then use Audyssey. Very smart to design your own cleverly desguised traps. I was going to call the Real Traps guy back about the planter ones they offer, but all their stuff is pricey. I have two corners where I can place plants and 2 where I can place a fair size piece like an auralex LENRD on the floor. There is no WAF for obvious panels. I will post some pics of the room in the other thread I linked too. Thnx again.

SoundofMind,

I built four artificial plant bass traps that look way better than the Real Traps, corner placed. I purchased woven pots 21" diameter and 21" high that took 4 square feet of 6" Ultratouch each (they smooth bass above 100hz well, also do some diffusion). Cost was $250.00 for all four (Real Trap arificial pots $199.00 ea) and the wife picked the artificial plants for the high WAF, (2 ferns, 1 ivy, 1 eucalyptus)! Audessey MultiEQ XT in the Denon and the Antimode brought the WAF over the top!

Good sound to you!

^ Cool. If you have links to that Ultratouch product please post, as I'm not sure my search is yielding the correct thing. I know this is not a very active thread, but I suggest we continue this here.

Hi folks. A newbie here. Some help please: I want to start a new thread/find an existing thread that discusses initial speaker configuration problems with the 2808ci. I can't get the Denon to show the presence of my side surrounds. Thanks for any help, and I apologize for this off topic post. Rich

Do you have a 5.1 or 7.1 setup? If 5.1, are the side surrounds plugged in to the "surround" speaker posts or the "Surr Back" speaker posts?

Hi bheronman, are you running 5.1 or 7.1?

If 5.1, make sure the two surrounds are connected to Surround R and L, NOT Surr.Back Right and Left.

If you click on the Audyssey Setup Guide in my sig you'll read that "0" phase is equivalent to "+".

I am running 5.1. Surrounds are Acoustic Research model AW 877 wireless speakers. The connector (to the receiver) wire from the transmitter has a mini jack, and comes supplied with and a y-adapter with red/white RCA connectors that I cannot connect to the speaker wire terminals. I therefore connected them to the "Pre Out" section, where red and a white female RCAs are available (marked "SL" and "SR "--there is another set of RCA connectors marked SBL/R but I do not have the speakers attached there), but the Denon does not detect them as present in this configuration (the "transmitting" light does not come on on the transmitter and nothing is "sent" to the surround speakers). When I run the Auto Setup for the speakers, the Denon does not send a tone for the surrounds as it does for the fronts, center and sub. The sub woofer connection is located in the "Pre Out" area also, and is detected by the Denon and works. The surrounds also come with an adapter that fits the headphone jack and when I use this, the transmitter and speakers work. I therefore see the problem as 1) the y-adapter is faulty, 2) the "Pre Out" terminals cannot be used in this way, or 3) the "Pre Out terminals marked "SL/R" are not working. I am betting on #2, but don't know how else to hook these specific speakers up since they have the connector adapter with the RCAs on it. I tried to get another y adapter at RS but they did not have one so I couldn't check that possibility. I haven't tried to "reset the Processor" as suggested above, but will in the morning when I am not so bleary eyed. So here I sit, frustrated, but loving the sound I am getting, sans surrounds, from the Denon. I have--and I know this is going to sound weird-- Allison 9s for fronts, a little Polk cc and a REL Strata III sub.. Thanks for any help. Regards, Rich
