*OFFICIAL* Denon AVR 391 / 591 / 1611 Owner's Thread - Page 140

The TV is mounted and one HDMI cable is pulled through the wall. Like I said before, surround sound is to come. Work in progress with the better half. :-)

^^
Try connecting the sources directly to the TV to determine if it's the TV speakers with the issue as well as connecting the 591 HDMI to the other HDMI inputs on the TV. Lastly, you could reset the microprocessor (p. 70) on the 591.

I'd also consider replacing the 591 with an HDMI switch which would pay for itself not using the power you're using for the 591.

Oh thank you, silly me; no wonder I couldn't find it.

So with the speaker wire connections all good, what else could be causing the 1611 to shut itself off and ending up with blinking red lights on the on button?
Any and all suggestions will be greatly appreciated.

^^
If the wires have all been visually checked at both the AVR and speaker ends (as well as the wire itself if run through the wall ... can be split from nails in the attic), then other causes are as follows:

red power ring flashes ....

every 1/2 sec - running 4 ohm speakers too loud (lower the volume) or amp failure (repair required)
every 2 sec - poor ventilation (need at least 3-4" clearance around the AVR)

^ Im running 6ohm speakers so I don't think there's a problem with volume on those right?

I'll wait till it happens again to see what's the speed of the blinking red lights, and recheck all wires meanwhile, thanks

^^
Shouldn't be, but all speakers dip below their "nominal" rating so it's possible. What is the master volume when the AVR shuts down?

I have it on absolute, and I don't think it's ever been above 50%, probably in the 30's

I'll bet you can remember. A flash every 1/2 (0.5) sec. would essentially look like a strobe or flicker. A flash every 2 sec would seem very slow compared to that.

Though I realize this does not directly address your current concern, I would suggest you consider connecting some sort of external speakers to your 591. I'd imagine that almost anything will be a substantial upgrade over the built in TV speakers and it may also resolve your specific problem.

When I got my first Denon receiver (an AVR 1610) I initially ran it with some old bookshelf speakers that I had laying around, then I gradually added and replaced speakers to build up to a 5.1 system. The receiver did a good job of summing the surround audio to match whatever speakers that were enabled in my system (I ran 2.0, 3.0 and then 5.0 set-ups before finally getting a subwoofer and finally running 5.1). I just want to make sure you know that you don't have to connect an entire 5.1 system to start properly making use of your AVR (as opposed to relegating it to HDMI switching duties).

OK, it just happened again, definitely red light blinking every 0.5 secs, happened with 47 absolute volume on 6ohm yamaha speakers and 16awg wire


Odd thing is I don't recall this ever happening before when I used it for 3 months just for radio with the same speakers/wire, probably reached this volume too

^^
Could be a short in one of the speakers. If you can reproduce the shut down on command, disconnect all speakers and add one back in at a time.

Can't reproduce at command, since as strange as it sounds it has only happened 3-4 times in 3 days, but other times I have watched for several hours without something happening, will check all speakers again.

Odly it has mostly never happened when the unit has been on for more than 45minutes, always first 15 minutes, once 45, forces me to turn everything off and wait like a minute before turning on, can't just instantly turn everything off and on

^^
If you can't swap in some other speakers to test, then the other possibility is amp failure on the AVR.

Is that possible tho, considering for 3 months it never once happened before when using it for radio and ipod, and only started when moving it to bedroom to use with tv?

All wiring seem ok but I'll dismount everything and instal one by one this afternoon just to make sure

Possible that an amp can fail? .... yes ... rare, but it does happen from time to time. If that turns out to be the case, your unit is still under warranty if purchased from an authorized reseller.

How would I hook up my android phone to my 591? I want to stream my amazon mp3 player on my phone over my 591. I don't see an auxiliary port on the denon.

Micro hdmi port is what I use. Mini hdmi for my tablet.

So a micro or mini usb to hdmi cable huh? Never thought of that, thanks.

Micro or mini HDMI to HDMI, not USB. Of course you need a device with an appropriate HDMI output, you can't convert USB to HDMI.

Thanks, I appreciate the clarification. Unfortunately I don't believe my devices are capable of hdmi. Do I have any other options. Auxiliary?

^^
I hook my Android up for music using an 1/8th inch stereo to rca (red/white). Very simple...

I have a Denon 591 AVR and LG BD570 blu ray player. Occasionally, when playing DTS-MA encoded movies, instead of the movie soundtrack I hear a loud noise which is more like very loud pink noise. This has happened with the LOTR extended edition as well as Avatar. It's intermittent and happens only when loading/playing a disc for the first time. If I stop and play it again, it plays fine.

Of course, I have the BD set to 'primary pass through' i.e. DTD-MA bitstreaming, and have the latest firmware installed. Is the problem with the BD player or the AVR? How do I start finding the source of this problem? The noise is so loud that I am afraid that it will damage my speakers.

Thx.

I would advise you to try running the audio through your TV speakers but then you wouldn't be running master audio through it. Does it only happen with the master audio or are you able to test it with Dolby Digital to see if it still happens?

No, it's never happened on Dolby Digital.

^^
Try setting the BDP to PCM vice bitstream and see if that resolves the issue. If yes, there is no change in audio quality with the setting.

I have encountered the same problem a few times on my 1611. It has only occurred three or four times since I've had the AVR and I've resolved each time by power cycling the AVR, but it's certainly a shock when it happens!

What BD player do you have? Does it make a difference if you switch to PCM as someone above suggested?

Do you think the noise is loud enough that it will damage your speakers?

I'm still wondering if it's the AVR or the BDP. Could be the BDP intermittently corrupts the raw bitstream it sends out, so the AVR can't decode it right or can't detect that its DTD-MA. Some one on another forum about popping noises with DTS-MA had suggested upgrading the HDMI cable to something that could handle higher bitrates. I'm tempted to try that out. I'm currently using a mediabridge/amazon HDMI cable.

Thanks jdsmoothie for the suggestion. I'll give that a try, but I'm surprised that this wouldn't cause any degradation from DTS-MA.

I have an LG BD570. I have always run it with bitstream and the issue has only happened infrequently, so I can't speak to whether setting the player to send Multi channel PCM has an impact.

It's hard to say whether the player is the problem, but power cycling the AVR has always fixed the problem for me without doing anything to the player. Like you, I believe it has always been DTS-MA codecs when I have had the problem. Usually at the very beginning of a feature presentation ( following trailers). There is probably some sort of audio format change cue that is being missed, causing the receiver to decode incorrectly, in which case using PCM might be helpful.

As for damage to speakers, it sounds possible, but so far I haven't had damage. Of course, I am quick to grab the volume knob and/ or mute button!

Interesting that you have a bd570 too.
