I just received a refurbished unit from A4L that was DOA (no output from the speaker terminals or preamp outputs, front display would not illuminate). The merchandise request was approved yesterday, but I have yet to receive a shipping label from FedEx. Has anyone here experienced a similar delay? It may be a good idea to start a log that tracks the redistributed lemons from Denon.

What time was it approved? Its only yesterday....believe mine came on the next working day but don't really remember nor do I think its a big deal to wait a day or two for them to set it up with Fedex....you'd need to do any tracking of units by s/n and get everyone to play to be of any use and that's not likely....YMMV

Yesterday morning, I'm just a bit frustrated with the entire process. I would really like to avoid receiving another dud but A4L will not allow me to upgrade to a new unit without paying the initial and return shipping costs. To make matters worse, shipping between California and Florida is 5 days each way, not to mention the processing time once they receive the unit. I initially purchased the unit so I could dedicate my Marantz to 2 channel duty with my Parasound amp. I guess I'll have to dig out the old NAD 5 channel that's buried in storage.


1st world problems.

not unlikely

I had some serious issues with Panurgy a couple of years ago

I assume that is still their master repair center?

Hi All


I am using the following components : AVR4520 and DBT3313UD Blu-Ray player combination.
This combination has been working fine for over 2 years, but recently have been experiencing audio drop-outs when playing certain Blu-Rays.
I assume the culprit is the Blu-Ray player, but I am posting on this forum, because I am aware that a number of members are using the same combination.


For example , I started watching "The Equalizer" disc and as soon as the movie started, there would be a periodic audio drop-out every 5 seconds or so. I removed the disc, added it again, restarted the movie but no change.
Now I know it is not the disc , because I had played this disc previously and did not hear any problems.


It has been happening at random over a period of the last 2 months, and wondered whether anyone has experienced anything like this.


Note: I powered everything down for about 10 mins, restarted everything and the audio drop-outs disappeared???


It is very frustrating to listen to, so any advice appreciated.


Regards
Phil

Some of the parts in the digital/hdmi board may now be approaching their end-of-life due to heat. The board can get really hot even with the avr internal fans because that board sits on top and collects heat from everything else inside the avr.

Try additional external fans to help cool your unit and hopefully extend it's useful life.

Get access to another BluRay player and see if you can duplicate the problem.

One possibility is that the problem is related to a combination of bitstreaming from the player to the AVR, 7.1 channel Dolby True HD sound tracks, and use of complex seamless branching on the disc, as that combination has been known to give some Bluray players, including Oppo players prior to the 10x generation, problems. The workaround for the Oppo players is to have the player decode the Dolby True HD soundtrack to LPCM and send that to the AVR, so I would suggest trying that. The only real downside to that approach is that it precludes the use of Atmos, but that's not a concern with the AVR-4520 as it doesn't support Atmos anyway. The example you provided appears to have a 7.1 channel DTS HD Master Audio sound track, but I'd suggest trying the same workaround anyway and see if it clears up the problem. If it's only happening with some titles, you probably don't have any sort of an impending hardware failure to worry about.

Did you re-seat the HDMI cable (on both ends) and/or try a different HDMI cable?

Yes, when the receiver is on.

I guess what I am asking is where in the unit produces the most heat? I have a Coolerguy fan and placed it on the back-left of the vent but I'm not sure if that placement is the most effective at dissipating heat.

Turn on your AVR.
Start watching a movie or listen to some music.
After the AVR has had time to warm up, touch the various areas on the top of the AVR with your hand.
Wherever your hand is when you scream the loudest is where the fan should go.

FWIW, my fan is on the top, left side, a little past the halfway point toward the rear.

After the amplifiers, the digital/hdmi board produces the most heat. It also collects lots of radiated heat from the 9 internal amplifiers. With the way the avr4520 boards are arranged, the hdmi/digital board cannot be kept cool unless the air above it is kept constantly refreshed.
My suggestion is to keep the air above the unit constantly refreshed when in use by using an external fan or perhaps positioning the unit as to leave lots of open space above it.

Since The Equalizer appears to use a DTS HD Master Audio 7.1 track, it shouldn't be a problem on the Oppo. I just brought up Oppo as an example where setting the Bluray player to output LPCM instead of a bitstream can resolve some types of problems.

This unit would be just what the doctor ordered for evacuating hot air out of the top of the receiver!

Thanks for all of the responses so far, much appreciated.
I have had this problem with 2 other discs, both of them where TV Series : Breaking Bad and Game of Thrones.
In the case of the Breaking Bad disc, I just removed the disc and reinserted it once or twice and the issue went away. For game of Thrones , it only seemed to happen on one disc ( #3 ) out of the four. No matter what I did this disc it would not play without the audio drop-outs, but all other discs where fine???


When I turned everything off, I also checked the HDMI cables on the Blu-Ray player end and checked they were OK ( removed and re-inserted). I have not tried the GOT disc since the last problem, but may need to check it again


The next time it happens , and it does not go away, I will try and change from Bitstream to PCM and see if it goes away.


A number of forum members have recommend a cooling fan, I live in Australia, so not sure where I would source such a device and how to use place it for best effect. Any advice appreciated.


I will keep checking and see if I can find a pattern to the cause, hopefully it is not a hardware issue.

I'm thinking you have something wrong with the laser since you can sometimes play the same disc correctly. They can get dirty as I understand it.

I'd think you could google cooling fans electronics even in Australia....and the cooling fan would be for your avr.

ps And the one disc could simply be faulty or damaged....

Good Info. I had my Denon in open air (no cabinet) along with cooling fans but my Denon would still get hot (I tend to run my equipment pretty hard at times). I added a few Emotiva amps and now only power my heights and wides with 4 of the 4520's internal amplifiers. I now had zero issues with it going into protection mode and shutting down due to heat.
I know it is an expensive option but it adds a lot of headroom and with the decreased heat I believe my 4520 will last significantly longer.
Just my .02.
Blessings, Brian

Thanks

Hi All, just a quick question about the Audyssey set up with the 4520, the diagrams I have found such as this one show position 2 right of center and position 3 left of center with 4,5,6 in order starting in front of 3. When running Audyssey for the first time or after a full reset the GUI indicates position 2 left of center and 3 right of center. Then 4 in front of 1, 5 to the left of 1 and 6 to the right. Rear 7,8 are the same on both. Does it make a difference or is one correct and the other not? just curious thanks.

The only position where location really matters is the first one. That's where levels and delays are set. The rest of the positions can be essentially random as long as you don't stray too far from the sweet spot (2-3'). They are just feeding the algorithm more data about the distribution of acoustical problems in the listening zone.

Just picked up my 4520 at FeDex. Holy crap, this thing is big. Won't fit into my TV stand... oops. Wife doesn't know yet. Shhh.


Turned it on and did a factory reset. I won't be able to set it up until sometime this weekend, but am glad that it turned on and seems to be working just fine.

What a sleek looking, non-intrusive piece of gear. I'm in awe.

Glad to be part of the "club"

Hey folks,


since I have had my 4530 for about a week now I'm still learning and experimenting with mic positions to try and get the best sounds out of my system. I have played with slight variations of the recommended Audyssey placement and ran across an article this morning in search of other options (still think it could improve a bit in my room) over at Home Theater Shack where they tested the effects of different mic placements with varying results. For example the best result for my 101 type of set up was :


Recommended Setup Mic Patterns





101, 101B, 102 - Best Image Clarity and good frequency response coverage. All dimensions are relative to PLP Center (PLPC):
  1. PLP center
  2. 3 inches forward
  3. 3 inches up
  4. 3 up & 3 forward
  5. 3 inches left
  6. 3 inches right
  7. plus points for 2 other LPs (except 6-point MultEQ)
For 101B, first four points are relative to the high seat back "wings," the rest are relative to the seat back


I'm just wondering if anyone has tried these variations, I'll give it a go tonight to see if it makes a difference with my room set up, here is the link to the artice:
