Thanks, Petetherock


what was your solution the problem ? ( or did it just go away ? )


I just testet it again tonight, and it seems to be there / come occasionally from start ( ones every 1- 5 min. and then only for maybe 5 - 10 sec. ) but after 1 -2 hours it got less or disappears - maybe heat related !? ( saw 4. episodes of "blacklist" in row :-)


I really ( want to ) like the SR8012 ( and keep it ) and its build is nice, but slowly I lose the confidence, that it is releasably. ( as told, I have had two new SR8012´s, and they both did the same !? which is very strange ).


It could be something in the software, so it can be fix, but I dont have time to waite for the next update , if I have to return it - and what to buy then ( the X8500 is much more expensive here and differences not very big IMO ).


I will try to reset it to the orginal / first ? software version and see


and a correction., it is on both Dolby S, DTs, auro 2D and even direct multi ch from the Apple TV.


Thanks again for responding, Pete

I am wondering if it is something with the Apple TV. Have you also checked the speed for your internet connection?


No, I have a hardisc recorder with tv tuner too - on a another HDMi input , ( tv over the air ) and the error is there too !


But I will try my BR with stereo music played back with Dolby S and see if its there too ( couldnt hear anything in the Atmos disc, I have tested for now - but it is hard to hear with sound in all channels at the same time ).


Thank you for the proposal, rwestley

I do not know if you approach me, but I do not hear noise but distortion of the sound out of the center channel - clear distortion and easy when listening to the voices in particular and I do not hear very well ! ( others hear it too, have checket ).

I never see this problem in the 8012 ,you have some possibility.


first ;you need try other center speaker ,after that you have samething problem.
second ;check connection and wire replace wire for shur this wire is not the problem.
third ;disconnect the speaker center and make new calibration and after collect your center speaker and make calibration manual just for your speaker center and try.
you have samething problem after you try all.
something wrong whit électric connection,how your 8012 is connect ,you have safetybar between your wall plug ,you need check that and for thy end ,is possible your problem comming form your system cable compagny,maybe box cable etc etc.


the problem stay after all that ,you need try other receiver and you check ,the problem gone whit they other receiver,I dont know maybe Inside the 8012 is not compatible whit your system.

- Better shielding, copper plated chassis.

They can't say it has better preamp, DAC and HDAM because they don't. On the video side, I am very curious to know what they are going to say, because D&M has done a good job standardize across many models. I just took another look of the video block diagrams for the AVR-X6400H and SR8012, they are identical except the 8012 has one additional component video input.

Did you read the AH review on the SR8012? Like many other flagship or near flagship AVRs reviewed, it received 5 stars for audio performance. On the bench measurement side, there were two surprises, the protection circuits tripped at above 1.2V rms and the 3 rd order harmonic byproduct was about 3 dB higher than observed on the Denon AVR-X3300W, still very low at 0.0018 % THD. Such minor difference in harmonic distortions is understandable because while they have the same pramp ICs, the SR8012 has an additional buffer stage, that is, the HDAM. The noise floor on the FFT chart was exceptional, 20 dB better than the X3300W, though it was only measured at 1 Vrms vs the 2 V for the X3300W. I assume that's because at higher output the protection would shut the unit down.
Thanks @avman09 and @bigguyca for your insight. I tested the AV7705 vs the SR8012 over the weekend, as suspected the 7705 had a nicer sound with better separation and a more forward presentation. I'd say the 7705 improvement was noticeable but not Night/Day.

However... the video playback on the 8012 once again was much better! There was better detail/clarity, and MUCH smoother playback during pans and sweeps. We also feel like there was a bit more color pop in the picture. We did the A/B comparison using same cables and sources.
To add to our confusion, I heard that the video processing is the same on both the 7705 and 8012 models, so I don't know why I am getting these results...

I was hoping to switch to seperates with the 7705, but with the video test results favoring the 8012, it looks like I might have to stay integrated for now. I'm feeling pretty surprised at this.

A little information and an opinion:

While the digital boards, the top board in the back of the units, in the AV8012 and AV7704, use at least mostly the same major IC's, the layout of the boards is different. The video performance could be different due to who know how many factors. Bad guesses are about all that could be provided.

In a chain that includes an OPPO BDP-105 accessing and expanding videos to full bit rate, through an AV7704 to strip off the audio, to an LG B6 OLED, I've found that the LG does the best job at processing the video. The system is setup, as far as can be determined, so that the digital video just passes from the OPPO through the AV7704 to the LG with as little processing as possible. For reference, the LG also does an excellent job of processing Netflix content through a wired Ethernet connection, and stripping off the digital audio, and forwarding it to the AV7704 via ARC. That is a subjective judgement, and I'm not fond of promoting subjective judgements, but it's all that I can offer.

I use a power amplifier on the fronts and one on the center and if I switch the center pre-out with the front L - then the distortion comes out off the front L, that tells me that ( power ) amplifier and the speaker is ok - and that must mean that the distortion comes out of the pre-outset of the center channel, but I will try to connect another speaker directly to the built-in center amplifier just for good order)

second ;check connection and wire replace wire for shur this wire is not the problem.

Have checket that and again I have never seen a interconnect kable or a speakerwire who has made periodic distortion



third ;disconnect the speaker center and make new calibration and after collect your center speaker and make calibration manual just for your speaker center and try.

The distortion come with and without any EQ

you have samething problem after you try all.

This is the second new SR8012 that I have had the same problem with - which is very unlikely that two of them should have the same exact error / problem ( and if I put my old Onkyo SS-preamplifier back on, there is no distortion.

And so far I have not been able to provoke the error when using my UHD bluray player.
a very strange and unusual periodic error.



thanks for all the suggestions, Zimmo

I am sorry for your problem,I cant understand why you have this problem whit this receiver, for me the sr 8012 is the best receiver for house cinema ,this sr 8012 is very srtong power and is very good for the music and you check all site they sr 8012 is very low problem compare to other receiver in this catégory.

Thanks, Zimmo


and despite the annoying error, I also like the sound of it, as well as the high build quality, especially in relation to its price.
When I find / solve the problem (right now it does not actually make the distortion) I have no doubt that I will be well satisfied with it.
All other real alternatives to it will also clearly be significantly more expensive here (X8500, MRX1120, etc.) and separate SS preamps are what I want away from.

I see the 8012 has 4+volts on it's rca pre-outs, but can't tell what the 6013 has. Would the A/V quality be same or should I spend the extra money and get the 8012?
Well you only live once 6013 is priced to compete with the AVR-X4500 If that helps. I bet you would not be very happy with a move from the AVR-X4400H to the "more or less" side step SR6013

You said it! I did a home demo with the SR8012, SR6013, and AV7705. Tests were done using the same cables and sources, and with a Monoprice Monolith 7 amping our lower 7ch SVS bed.

Surprisingly the 8012 had the better picture with much smoother playback compared to the 7705, and the 6013 seems almost identical to the x4400.

The 7705 sound was a slight improvement over 8012, but with our video playback results it looks like the 8012 is staying in our theater. A little surprising as we were ready to switch to a true prepro/seperate setup.

Ive had distortion from the 8012 and it was a firmware problem. Had to reset the avr and reload the firmware and the problem was gone. Worth checking out if you havent already.

I did opdate to the newest firmware ( and testet the firmware which was on it from the start before, and that did have the error too ) , but I didnt reset the AVR first, I will try that and see if that helps, thanks for the suggestion.

Anyone know if there's a way to biamp L/R while running 5.1.4? The manual seems to show it requiring the use of the top rear/rear height amp output for this, meaning I can't do it. I had to remove my rears to make space, and might as well gain a little headroom on the mains for when I'm feeling frisky.

edit: Ah, found it in the menu, there's a "speakers for bi-amp" option that lets you change it from the top rears! I'll hook that up tomorrow

Don't count on it. If you want more power, use a more powerful external amp.

Zero need for that, this is just for when I'm listening to two channel music. I'm quite sure the 8012 isn't going to run out of transformer with only four amp channels in use

My point being … no real additional power provided using the bi-amp mode.

Wait really? It should provide an extra 3 dB of headroom, do they cut the power to each output in half when you use that mode or something?

There is only one power supply. It doesn't magically come up with additional power simply because you're connecting an extra two wires to it.

By your logic, any single of the 11 amp boards would be capable of maxing out the power supply. That doesn't really make sense. There are other limiting factors before you hit the limits of the power supply.

Total output power even climbs ~125 watts driving seven channels compared to five, see https://www.audioholics.com/av-recei...12-bench-tests - I am sure the increase is larger going from two channels driven to four. I was just looking for a way to actually configure which secondary channels it uses for biamping, and found it. If you know an actual technical reason it won't actually use the secondary amp boards to provide more power to the speakers, I'm all ears

edit: Found some good discussion here, https://www.avsforum.com/forum/91-au...-powerful.html - I'm still going to hook it up and take my own measurements just for fun, there's zero cost involved and I'm curious.

Total output power even climbs ~125 watts driving seven channels compared to five, see https://www.audioholics.com/av-recei...12-bench-tests - I am sure the increase is larger going from two channels driven to four. I was just looking for a way to actually configure which secondary channels it uses for biamping, and found it. If you know an actual technical reason it won't actually use the secondary amp boards to provide more power to the speakers, I'm all ears

edit: Found some good discussion here, https://www.avsforum.com/forum/91-au...-powerful.html - I'm still going to hook it up and take my own measurements just for fun, there's zero cost involved and I'm curious.
There are literally dozens of posts over the years (including the one you linked to) on how futile using an AVR's "passive bi-amp" feature is. However, that doesn't "always" stop someone who has purchased the external amp from claiming it sounds better to justify their purchase while many others will claim no additional benefit and return the external amp.

Hello everyone. My marantz sr8012 has started to cutout the sound for a few seconds and comes back in. Sometime it won't come on period when using my nividea shield. When i switch to cable tv and blu ray it plays fine. my hdmi cable I'm using is high quality and only 6 months old. The receiver isn't used very often and it was purchased last October. Any ideas?

Check the connectivity of the HDMI cable as it could simply be loose, otherwise, try other HDMI inputs and another HDMI cable.

If the only issue is with the nvidea shield, more likely a nvidea shield issue.

So i've had my 8012 for several months now and am loving it. I dont have Atmos speakers yet so i have it set up (- ) those speakers, nor am i using another zone anywhere or streaming through its options other than Google Play (phone).

Two minor glitches so far, i think the first issue "may" be a handshake issue but not sure. Once in a while i'll fire up a movie and notice the display on the 8012 is just showing DTS, not DTS HD MSTR/ neural-X or Dolby Atmos based on the movie's audio output selection. I confirm with my disc player that its sending Atmos or whatever format but the AVR still only outputs and displays DTS. Last time i just shut the 8012 off for ten seconds turned back on and that fixed it, so not sure of that glitch.

Second,,,,, at times if i'm watching a movie and i respond to a text on my phone, the 8012 kicks "out" of the Blu-Ray setting right into the Bluetooth setting I have to manually re-press the Blu-tooth button on my remote to continue the movie. Also when i want to pair up my phones (google play) to my JBL Boombox, the 8012 will actually turn itself on,,, i mean on from been powered off lol.

Otherwise so far everything else i couldn't be happier with for a living-room set up. Very happy with this purchase.

-Marantz SR-8012
-Yamaha BD-A1060
-Funk 21.0LX Master/Slave combo 4800 watts RMS/9600watts (peak)-
-Chane A-2.4 L/C/R
-Chane A-1.4 side/rear surrounds.
