Well, I'll just have to make do.

I'm still experimenting with center channel speaker placement. Sound is improved, but not quite "there."

Thanks,

I think that if auto-setup systems like YPAO have any shortcomings it's that they have led us to believe that there is such a thing as a one-click solution to perfect setup. Or than all inadequacies in speakers or room can be "fixed" by the AVR. You might be surprised how little it takes to abate room issues or at least reduce them to a point where YPAO can compensate. Keep making small adjustments and be patient, give yourself time to adjust to changes.

Unfortunately I have the RX-V2065, which only offers a single point calibration. Otherwise I would have definitely done it on every seat in the house :P

FWIW it only did -1.0 db on the sub, distance was about 14 ft compared to the mains 11 ft despite them being right next to each other. I bumped it up to +0.5, adjusted the distance a little and things sound great so far.

It is pertinent to note that Room EQ softwares systems are not perfect..
Even Yamaha YPAO which was 1 of the first has been refined at least 4 times times since its introduction. Its early versions often told the user his loudspeaker was out-of-phase when it was really phased correctly and the YPAO software was unable to tell the differences for room reflections..

When we do an install, we first run the noise sequencer manually using an SPL
meter, setting the loudspeaker specs manually and then monitor closely the sound stage..

If some EQ is required then we add as little as possible since the THD can rapidly increase here.. Our objective is to get the room and loudspeakers to sound as neutral as possible so that any tonal compensation is to help optimize the source material as it may be a little deficient in bass or mid-range....

Just my $0.02..

Multi-point setup is a trade-off too. There can only be ONE sweet spot. Especially where LF response has null points in the room.

With the mic auto setup, and having sub on back wall ( opposite of mains), does one set sub to 180 degrees or 0 degrees. I ask because does the mic correct for phase on sub? If so do you keep sub set to 0 degrees and mic does rest?

Leave it at 0.

Any definitive solution to this problem since last year? I just set up my A2000 and noted the same problem, especially the center channel sounding really odd--really flat/hollow sounding. I've only done the auto single point YPAO setup, so I'm going to redo with multipoint YPAO or even just manual, but wanted to see if there were pointers to maximize the results.

Thanks!

Good luck. I have a RX-Z11 and never got the YPAO to do anything satisfactory for me. I ended up borrowing a spectrum analyzer and used test tones to set mine manually. The results were far better, in my opinion.

The same here. I ended using an iPhone/iPad app to get the speakers balance. The only time I used ypao was to make goodman magnums have the same sonic profile as my focal chorus 800's

Hi Everyone,

Thanks for the discussion, it helped me a lot to finally come to a conclusion that YAMAHA YPAO is a crap

I have YAMAHA RX-V673 and I have been trying to set it up for optimal results but failed

I tried YPAO many times and then tweaking manually but no found satifactory results

Can somebody help me and provide me the Parameter EQ values for the optimal settings?

Appriciate you help

Thanks

Despite NUMEROUS attempts, I could never find settings with YPAO that were satisfactory with my RX-Z11. I ended up buying an old-fashioned analog equalizer with slider scontrols for my main channels and set the center/surround speakers to match the timbre of the mains as close as possible. The results were far better, in my opinion.

[*] If you are going to use YPAO, you must use multiple positions to get acceptable results. I moved the mic around the listening area (i.e. my living room) until all 8 positions were filled. Result: much more accurate settings for distance (sub was now 14 ft away instead of 25 ft as originally calibrated) and speaker size (front/center set to Large, surrounds set to small. I'm going to set all speakers to small, but for music setting the mains to Large does seem to offer a bit richer sound).
[*] I cycled through the YPAO settings and found that 'flat' sounds the best to my ears. YMMV.
[*] That said, for 2-channel stereo, 'Pure Direct' was hands down the best-sounding choice. (Doesn't Pure Direct turn off the PEQ settings?) Imaging was excellent--from the listening position, I would have sworn the center channel speaker was on...and I would have been wrong! 'Straight' was a little better than 2-channel, but both seemed to have less clarity and vibrance than Pure Direct.
[*] 7-channel stereo sounds pretty darn good with the new YPAO settings. Better than my SPL meter? Impossible to say, because I wasn't doing a double-blind test. But it was certainly a very enjoyable listening environment.
[*] For movies, center channel dialog still sounds "off" to me, like the actors are talking in a cave (i.e. a little bit of an echo). I'm going to try moving the center speaker which will hopefully correct the problem, though of course I will need to recalibrate.




So, except for the center channel, I'm pretty happy with the setup. Unfortunately, for home theater use, that's a pretty big exception. Hopefully, I can get it cleared up.


Thanks all for the tips and encouragement,

Mike

I had an HTR-7065 for a bit(took it back to Costco and got a Pioneer SC-1222-K) and I also had issues with the center channel having an echo, so after turning off the YPAO parametric equalizer, that mostly got rid of it.

Dear friends,

I have Yamaha RX-V667 & have not found best way to caliber parametric equalizer.I just read that YAPO can be run with different settings & all results are saved independently.
So is it true with 667 too?ie.I can 1st select "FLAT" & then run YAPO, try "Natural" & save results again.
So can I select between two(total 4) & get sound difference?

Pls. let me know to use parametric equalizers.
Also I checked manual settings & there are few more options other than equalizers,some thing like Q gain so so.
So how to use them?

Pls. guide me.
Thanks.

You just run YPAO once and it saves settings for all the modes. To switch YPAO modes you then just go into the Manual Setup menu and select Parametric EQ, and choose Manual, Flat, Front, Natural or Through (Through means the EQ is disabled).

I would compare the 3 YPAO modes and also try Through. Manual is only useful if you know what it is about the current sound that you want to improve, it's not really a good idea to play with the manual EQ settings unless you know what you are doing. (i.e. exactly what problem you are trying to correct).

After running YPAO you should also make sure all your speakers are set to SMALL, that the bass crossover frequency seems reasonable, and change the subwoofer level up or down if you want more or less bass.

I recently purchased a yamaha RX-A3020 to replace my DENON 4311CI. YPAO with 8-point position correction is great and found it better than Audyssey XT32 on my previous DENON.

I thought that bass was weak after an audyssey correction but smooth and tight with YPAO.
ThecRX-A3020 has a "DALOGUE ADJUST" setting which significantly improves the centre channel. As one who has done a 32 -position with Audyssey and 8-position correction with YPAO, my personal preference is the latter.

Making adjustments on my rxv671 have been driving me nuts... First set everything up manually, distance, sound, used a sound pressure meter matched all speakers, found the perfect spot for my sub and what was lacking was clarity from my center channel. I tried every possible setting on the reciever and still center channel was muffeled. My wife was yelling at my last night, her voice was piercing my ears, i went and looked up sound levels for the human voice, found out the human voice ranges feom 500hz-2000hz, so i ran ypao copied the settings over to manual, cleared out the center channel and manually adjusted the bands and frequencies, +1.5 on 500hz, 1000hz, and 2000hz and BOOM sound was great, you can hear kenny powers low tones and high tones clearly, words where poping right out the speaker, you can hear actors breathing from there nose. There are other options in the manual e.q. settings I dont understand like the q option, i will do some research and try to tweak. Anyways I hope this helps anyone trying to get clarity from the center channel.....
