The "Official" Denon AVR-2808CI Owners Thread - Page 117

^^
There's likely over a dozen active Denon model threads going back almost 4 years. Sounds like amp failure if you have no speakers connected and it still shuts down. The microprocessor reset procedure should be listed in the table of contents of your Owner's manual ... near the back of the manual which is always worth doing before throwing in the towel. You might also want to pop the top and see if there are any blown fuses you can replace. If the decision is to replace it, your best bet on a limited budget, if you have Best Buy stores nearby, is to try to grab one of last year's lower level XX11/X91 models that have been on clearance now for a few months which should be within your budget.

i'm using a 2808ci but i use two separate amps, a 2ch. and a 3ch. none of the denon's amps are active.i was told that the equalizer in the denon has no effect on the sound because i use separate amps. is this true? i never noticed much difference when i changed eq settings before i bought the amps either.

^^
No it's not true. Audyssey MultEQ XT still works with external amps; however, you must rerun AUTO SETUP again if you haven't already done so since adding them.

what if i don't use auto setup? i just want to make manual adjustments. i don't get the audyssey thing i didn't hear any difference when i did it.

You may have done it incorrectly then as you should have noticed some difference from no EQ at all. Suggest you review the Audyssey Setup Guide linked in my sig and run it again. Regardless, if you are using the manual EQ, it would still apply to the external amps.

i've read the guide carefully i used a tripod in several locations but nothing changed.i'll try again but i'd rather make manual adjustments with the eq. why don't i have the control i used to have with the old slider type equalizers?

Because the intention is that the vast majority of owners (98%+) will use Audyssey.

how could audyssey know what i like?

Suggest you review the Audyssey website to learn more about the technology and how for the vast majority it will EQ their setups better than they could hope to do manually.

on the broader point -- ANY setting (whether you are talking about Audyssey EQ, manual EQ, tone controls, night mode, whatever) will affect internal amps or external amps equally.

anyone who told you otherwise doesn't know what they are talking about.

all of that processing happens in the PRE amp stage, the receiver doesn't care where the amplification takes place. At the end, once all the processing has taken place, the signal runs through the DAC's and then the pre-amp stage is done, and it heads to the amplifiers. Whether the amplification then happens internally or externally is irrelevant, all the processing is over and done with.

i've never been satisfied with the bass in my system can audyssey help with that if done correctly? it's not the low end bass,i have two subs for that the problem is the slightly higher frequencies.

If you want to run direct to your amps with no processing you need to use the EXT IN multichannel inputs and the preouts. This will bypass the processing and essentially the only settings that apply are the distance settings and channel level as well as the volume control. If you are using the analog 2-channel inputs I believe you bypass the processing as well with the pure direct function. Any of the digital inputs will run through the Deonon DACs and processing settings.

My HT gear is located in a remote room away from my living room:
Denon AVR-2808CI
RF remote: Logitech Harmony 900
Speakers: [A] 5:1, [b] four sets of stereo speakers (in various rooms) on a speaker selector: Niles SSVC-4
Projector: Panasonic PT-AE2000U (the only video monitor) in the living room is connected using a CAT-5 cable from the HT gear closet with Niles C5-HDDA baluns on Component Video Out.
Other AVR connected equipment: Fios Cable Box w/DVR, CD player, Blue-Ray Player. Also in this room: incoming Fios Internet, WiFi router.

I'm hoping that forum members can validate or comment on two HT additions that I'm contemplating:

1) Since my projected image is in the living room, I'd like setup a "mirror display" in the HT gear room by utilizing an existing Apple Cinema Display (A1082) using a DVI to HDMI adapter (Female to Female) and HDMI cable to the available HDMI [Monitor OUT] on the Denon AVR-2808CI (the projector uses the Component Video out). This would allow me to see my screen while I'm in the HT gear room without having to turn on the projector and go back and fourth. I could also use the controls on the equipment, or original IR remotes for individual equipment and not have to rely on the Harmony 900 RF remote if I need to trouble-shoot , again without walking back and fourth to see the results on the projected image in the living room.

2) I'd like to connect an Apple TV to the AVR-2808CI and use it to stream content using AirPlay, stream video via Netflix, etc. Connected to HDMI in on the AVR-2808CI and to Fios Internet via Ethernet cable to an open port on the WiFi Router.

Any problem with the above? Appreciate input from the community.

^^
1. This is fairly common with a PJ as the sole display so as not to have to fire it up, however, note that although HDMI-DVI should "technically" work, it really depends on the device itself as to whether it will handshake properly with the AVR.

2. This should work without issue as it's no different than connecting another HDMI device.

Thanks very much jdsmoothie!!

I have a 2808CI that I have been running, Sony Bluray, a Samsung LED TV, a Scientific Atlanta Cable box, and a MacMini (for iTunes and to use the Samsung as the display for Aperture). I use a switch box to switch between the HDMIfrom the MacMini and the HDMI from the BD player. I have it set up to be a 5.1 system.

My issue is that although I seem to be able to get 5.1 sound from the BD, I get no surround channel from either the MacMini or Cable TV. I'm pretty sure that it's in my setup, but can't seem to figure it out. My goal is the best possible sound out of iTunes and rented iTunes movies as well as surround out of the cable box.

Any suggestions?

The project to hook up a "mirror" display on the HDMI out (with a DVI converter) failed, I get quick blinking power light on Apple Cinema Display, but the monitor does not light up and I'm abandoning that project for now.

More importantly, I've run into a wall with my installation of the Apple TV... (As I initially described) I'm using Component Video out on the AVR to connect my Panasonic projector (over CAT5 with baluns) and now I can't "see" my HDMI DVD IN connected Apple TV (which works, I've tested it on another HDTV in the house). After re-reading the AVR2808CI manual I realize that HDMI IN requires the monitor/projector to be connected to HDMI OUT. Since I'm not utilizing HDMI for any other devices, I suppose (3 years ago when I set it up) I must have been aware of this limitation with connecting the projector using component video over CAT5.

So how can I make the Apple TV work with my setup? My objective is primarily to stream Internet audio and iTunes music, but I need a monitor to control the Apple TV menu system.

Some more details:
^^^^^ @ jwaugust

How is cable box connected to the denon?

When you are trying to debug surround sound issues, it is vital to 1. Check the input signal and 2. Check the surround mode (output). Can you ease report what the receiver says for this when you're trying to use the Mac mini or cable box?

^^^^ @ josty

You may want to look into an hdmi>component converter like HDFury.

Then you could switch everything through the receiver and output hdmi to the converter for all sources.

My wife found my kid pushing the on/off button non stop. Right as she pulled him away the receiver powered offnand now we can't get it on. Could he have shorted it out?

^^
Remember there are (2) power buttons .. the larger one is the ON/Standby button and the smaller one is the ON/OFF button. First press the smaller one to set the AVR to standby, and then press the larger one to turn the AVR ON. If still no joy, unplug the AVR for about 30 minutes and let it sit. Then plug back in and power on in the order above.

Thanks

If larger button is standby, why would I push smaller one for standby? I always thought smaller button stayed in, to enable larger button to serve as on/off button?

I am having problems with my AVR-988 only when bitstreaming. The problems, as also verified by the on screen display of the AVR, are: 1) AL24 processing does not kick in neither in STANDARD nor DIRECT/PURE DIRECT mode; and 2) multichannel audio (lossy or lossless, except PCM) collapses to 2 front main channels immediately after switching to the DIRECT/PURE DIRECT mode. As a side note, I do not know whether these existed from day one.

Regarding the possibility that the problems may stem from my BD player: They do not stem from my Oppo BDP-83 or from BD players in general as I tried a friend’s bitstream capable Sony BD player which has only HDMI input. In the said players secondary audio was set to off. In the case of Oppo, it was set to HDMI as the Primary Output and I also tried Source Direct and 1080p for resolution setting.

Regarding the possibility that the problems may stem from my AVR: I have the problems when Audyssey is disabled. When Audyssey is enabled, the only settings which may be relative to my problems in the AVR menu seem to be are Auto Setup/Option/Room EQ (1.2.1), which is set to “All”, and Menu/Auto Setup/Option/Room EQ /Direct Mode Setup (1.2.2), which is set to “On”. The problems continue to exist despite the said settings.

Regarding the possibility of the HDMI cable connected to or to the HDMI input port of the AVR: I tried another cable on another HDMI port on the AVR. Nothing changed.

After ruling out the above possibilities, to counter these problems I unplugged the AVR for an hour or so, reset the microprocessor and installed the latest firmware (the most recent one that fixes the audio issues of Star Wars blu-rays which also includes the fixes provided in the previous firmware) but they did not solve them either.

I took all of the above-mentioned steps per the suggestions of forum users Sam S and jdsmoothie. As a matter of fact I frankly do not have high hopes for solution. However I wanted to hear the opinions of the users of AVR-988/2808CI as a last resort.

Any help would be greatly appreciated!



PS. Although I don't think the following would have any effect on my problems, I would like to note them nonetheless due to the mysterious nature of my problems: I had imported my AVR-988 in brand-new condition to Europe and am using it with a 120 to 220 voltage converter and regulator. There is also the Hz issue, which cannot be changed-- normally electric appliances work on 50 Hz in Europe whereas on 60 Hz in the US.

Neither of those are "problems". That is behaving as designed.

1. AL24 only operates on PCM signals
2. Direct mode "collapses" down to 2 channels unless it's a multich PCM signal.

On newer models they changed Direct modes to not collapse multich bitstream. But AL24 has always only ever operated on PCM.

His point was that the kid might have accidentally pushed the little button, preventing the receiver from turning on via the big button.

First of all thank you very much for replying.


Does not this contradict with the description of AL24 processing plus availab on page 63/61 of AVR-2808CI/AVR-988 manuals?


Does not this contradict with page 37 of AVR-2808CI/AVR-988 manuals where it states "the sound is output to the same channels as the input signal" under the "Direct Playback" section? I don't see in the manuals differentiating PCM and non-PCM signals in this regard.

When playing a 5.1 HD audio track on my 7.1 system, my Denon AVR 988's on screen display shows the matrix mode used with 5.1 Dolby TrueHD (except "NON MTRX" mode) but it does not show any matrix mode used with DTS HD MA or HR, even though MTRX ON, PLIIx CINEMA, PLIIx MUSIC and ES MTRX and NON MTRX are selectable options under Menu/Parameter/Surround Parameter and when any of them is selected the effect of the respective matrix mode is discernible.

E.g.: When I play a 5.1 Dolby TrueHD track with the matrix mode of "PLIIx MUSIC", "Dolby HD + PLIIx M" lights up on the on screen display of the AVR. When I play a 5.1 DTS HD MA or HR track with the same matrix mode, "DTS HD MA" or "DTS HD HR" lights up on the on screen display, as if no matrix mode has been selected.

What is the reason for the difference?

I've had the 2808 since it came out and it still works and sounds great. I'm just wondering why Night Mode doesn't work with DTS-MA? I had always assumed it was a bug or a 2808 / DTS restriction. I recently upgraded to the firmware provided by jdsmoothie (for the Star Wars DTS bomb issue). I was hoping with the newer firmware it would work but it still behaves the same way.

As a workaround, I decode on my Oppo BDP-93 instead and send in multi-channel audio. Night mode works with that configuration. However, I am still interested to know why it doesn't work for DTS when it works for multi-channel and Dolby True HD.

I am experiencing a similar problem as explained in my post preceeding your post and I have the latest firmware and Oppo BDP-83. I hope someone would reply to our issues so that we can understand whether these problems are unique to our AVRs and thus whether they stem from a defect.

I have a Denon AVR-2808CI receiver. It is hooked up to an HTPC which uses an Auzentech X-Fi Home Theater sound card via HDMI. I have configured PowerDVD 9 to pass-through the uncompressed audio in the settings and have also configured FFDshow to do the same for when I am using MPC HC. When I play files with DTS HD, Green Lantern for example, the video data from the program on screen, for PDVD9 shows 'DTS-HD Master Audio 5.1' in MPC the same movie shows, 'DTS, 7.1, 96000Hz, 1536 kbps (bitstream)' and the Output mode as S/PDIF. The Auzentech settings are also on Entertainment mode, the encoder is disabled and HDMI set. No matter what I do or play the DTS-HD MSTR light on my receiver never shows up. It only displays as, 'DTS Surround'. I've never actually seen that lit up on my unit. It will switch modes as different files are played, Dolby Digital, DTS Surround etc. but never displays the HD modes. I am wondering now if there was a bug in the unit and perhaps there was a firmware update available to correct this at some point? Can anyone offer any suggestions? Any insight you could provide would be greatly appreciated.
