My wife and I bought a Mits 52525 DLP set a little more than a month ago.

Now I need to look into buying a nice receiver and speaker system. So, it's fact-finding time for me and this forum has proven to be very informative. I've heard about the Yamaha RX-V series with YPAO (Yamaha Parametric Room Acoustic Optimizer). Is this a marketing-way of saying "frequency spectral analyzer"? I would like to hear from those of you who own or have a lot of experience with these units (esp. the V2400 & V2500s) on how well this optimizer works for your particular situation. In other words - does it really do what it claims it can do?

Yes. As to how well it does it, do a search...there are many threads on this topic.


I personally have a 1400. Just used MCAAC (Pioneer) for my mom's new set up. Both work.

I tried doing a search on YPAO effectiveness - not much out there. Again, I'm asking anyone who owns the 1400 or 1500 model and has utilized the YPAO function to reply with their evaluation of how well it adjusts for the room it's in - in other words, are you happy with the results?

i just recently bought a mitsu wd52725 and a yamaha rx-v1500 at the same time. i'm no audiophile by any means, but i have to say that the ypao setup was extremely easy and seems to have done a good job. the sound is a thousand times better than my old jvc 5.1 receiver. i've only had the yamaha hooked up for a couple days now, so i'm still learning things about it and playing with it. but, i haven't felt the need to tweak any of the settings that the YPAO did. hope that helps.

I replaced my denon 3802 with a yamaha htr 5790 and it has ypao and it is a wonderful tool to setup the rooms acoustics and it analyzes and corrects any faults.also sets speaker distance and equalization.

The Yamaha YPAO has demonstrated THAT TI CREATES MANY PHASE PROBLEMS as it corrects EQ anomalies...phase problems are even more troublesome than EQ troubles.

I don't own a Yamaha YPAO product, but the only place I feel parametric EQ is useful is for reducing the room/sub induced bass frequency modal peaks.


I don't believe Yamaha deals with Parametric EQ for the sub at all.


Personally I would go for an inexpensive parametric EQ unit on the sub-out channel only, like a BFD 1124.

I have a RX-V2400 and I think that the YPAO is great. It does tell me that my two front speakers are out of phase and they are not. That is the only problem that I have ran it to. I use the YPAO and then fine tune it just a little more for my taste.

They may be wired, mistakenly, out of phase internally from the factory. This happens more than you'd imagine.

Also...

The tweeters and woofers can sometimes be wired out of phase to each other on purpose in some speaker designs.

I have an HTR-5790, and for me......and this is just my opinion, nothing else......the YPAO tamed the highs way too much. It sounds like THX surround mode but worse. This could be due to several factors including room acoustics, speaker placement that I am limited to, personal preference in sound,etc., but I run the manual setup. YMMV.

I have Paradigm Reference Studio 100s do you think that they did not take the time to make sure. I only ask this because for the price I paid for them I would be most unhappy if they are.

A lot of people have had problems with the receiver (falsely) telling them their speakers are out of phase. Most likely, it's telling you you have a problem with room placement, e.g. one speaker close to a wall and the other not, so they appear out of phase to the microphone. So, yes, it's telling you you have a problem but you shouldn't reverse the speaker wires unless they really are wired wrong. To fix it (if you choose to do so) you are going to have to move the speakers or use some room treatments.

It happens quite regularly. Doesn't matter what you paid.

For an independent check of speaker polarity, move them facing each other and a few inches apart. Play some music, reverse the polarity of one of the speaker wires and play some more music. Whichever way has the most bass is correct.

I will try both of catapult and Nightrain suggestion. Thanks for the advise.

I do know that I need some room treatments but I am still getting the room put together(long process).

Thanks again guys

I like the ypao feature, but sometimes when i run it the center gets set to large then somtimes it sets it to small. Other than that its great. I think with any automatic set up your going to get an occasinal fluke (maybe it picks up some ambient backround noise etc.)

YPAO told me that my center speaker was out of phase, and it turned out I wired it wrong so it worked for me. :p

YPAO...I just re did the function last night since I re-arranged the room. There was no way for me to do an A/B test and compare so when I say that it sounded better after the calibration of the YPAO you can take it with a grain of salt. I will say however, that every time I run the test consecutively that the results are always the same/extremely similar. I just got my Rat Shack SPL meter back today, and when I get home will run through test tones and finally compare results of YPAO to me doing it manually.
