"Official" Audyssey thread (FAQ in post #1) - Page 251

I do have that short-term memory loss thing happening , but with my OP 885 I believe the button push was to move to the next mic position. And at each mic position, the sequencing from speaker to speaker - intra-speaker if you will - was automatic with the aforementioned ~15 seconds to move in, make the mic adjustment, vacate and "hide."

With the Denons you push a remote button to begin each set of chirps for each mic position. IOW take as long as you like to move the mic.

I need to keep in mind that the different manufacturers implement Audyssey differently with regards to setup process and procedure. Will preface future posts on these issues with "my Onkyo 885" from now on.

I trust you will point it out if I fail to do so?

Alpine has been shipping two products with MultEQ XT for about a year now. Check the Audyssey website, under Automotive, for more info.

I know we each take more pleasure in pointing out our stupid mistakes than our honest ones.

Gary, all of *my* mistakes are honest ones.

does changing speaker levels alter Audyssey's effect? I find that my sides and surrounds are too hot

Thank you Chris. It makes total sense now that you explained (hopefully not for the umpteenth time ) that the filters are calculated over a wide range for each speaker and are available for use even though in all cases some filters for both sub and mains will not be used depending on crossover setting.

You say Audyssey doesn't set the crossovers. Well then, what did? I see posts all the time where people say Audyssey set the crossovers at various numbers. Not so? After Audyssey ran, my speakers were set as Large with a crossover at 40. Does this mean that I had already set the crossver at 40 (and don't remember)? Or are you saying this because it was my Denon that set the xo?

Now that I think of it, David Aiken (post 7412) responding to my previous question about the -3dB point was mistakenly interpreted by me to imply that Audyssey sets the crossover. As I re-read it, I guess it is the Denon that sets it (based on Audyssey's measurements).

I gather from this that Audyssey MEQ doesn't do anything to find the "best" crossover. It just enables filters to accomodate whatever crossover I might happen to choose as best it can. I also gather that running Audyssey MEQ with different crossovers preselected would make no difference in the filters selected.

Can I purchase Pro?

EDIT: Well I tested all the crossover possibilities and Denon chose wisely setting the crossover at 40. The sub I am listening to is a cheapo, and the bass produced by the mains is much cleaner. I guess the idea about releiving the mains of part of their work by setting up the xo depends on the relative quality of the mains vs the sub.

Honesty and stupidity are not mutually exclusive.

Chris,
you stated this:
You can adjust the subwoofer level in the Manual Setup menu under speaker settings-->levels

does this mean levels settings for the volume or the difference value(levels) for the EQ frequencies.
thanks

Where are you buying the stand alone units. I want to buy one of the balanced units.

I prefer to think of it as ignorance.

$5k.

Howdy Folks....trying to set up audyssey in my new NR906 and all the speakers tweet but I get the "speaker detect error". Spoke to Onkyo tech and he had me reset the receiver, ran Audyssey and it worked, however before I realized it he had me set up 3 settings from the same location so....I put the nr906 in standby and started again [guess that freaked it out] now even after resetting the receiver I always get the speaker detect error even though all speakers tweet .

Any vodo I might try before I have to unhook everything and ship it back?

Thanks.

If any of your speakers have amps are the amp lights lit when you start Audyssey?

I've run the auto setup on my Denon 3808 several times now and I usually get slightly different crossover settings each time, but not so different as to be alarming. What is alarming however is that this is a 5.1 setup and all of my speakers (other than the center and sub) are identical towers. Despite being exactly the same, it sets my surrounds all the way down to 40hz while my fronts are set to 100hz. Is this wrong or just some sort of compensation for the room?

It's the room. Put a speaker a few feet from a wall and it will have a vastly different response, especially in the bass, from the same speaker close to a corner or other boundary interface. My three front speakers are identical and yet they rarely measure the same with Audyssey or other measurement tools.

So, don't sweat it.

Thanks for the help, you were really on the money. My surrounds sadly are a little too close to the walls as I don’t have the space I’d like. If I move them further away from the wall they’re right in my ear.
Should I manually set my crossovers to 80 across the board or just leave them? The reason I ask is that I know they can handle way below 100. In fact, it kind of brused my ego.

Subs are running off an amp which is on.

No. Leave them at 100Hz because Audyssey has not set EQ filters below 100Hz. Of course, you can try the calibration again and maybe you'll get another answer.

What mic adjustments need to be made during the ~15 seconds? I thought the mic needed to be left alone until Audyssey tells me to move it to the next position.

Is this because the xo setting of 100 indicated that the -3dB point of his surrounds was someplace between 90 and 100, and filters below the -3dB are either not set at all, or are not as effective?

So you can increase the crossover some, since Audyssey runs a full set of filters for the subwoofer and has them ready to use with crossover increases. Right?

Roger,

I meant the settings for the level (volume) of each speaker. You can't change the EQ frequency levels unless you disable Audyssey and go into manual mode.

Do you have a 5.1 or 7.1 system? If it is a 5.1 system, what terminals are the surround speakers connected to? They must be connected to the L Surround and R Surround and not the Back Surround terminals. That often causes the speaker detection problem.

The speaker roll-off point (and thus the recommended crossover frequency) is calculated from the combination of all the measurements in the room. So, yes, if you repeat the procedure and don't have the mic in the exact same positions you will get slightly different results. The differences will be small.

Also, it's not a matter of what your speakers can "handle". That's a purely theoretical number that manufacturers publish based on anechoic measurements and sometimes augmented by wishful thinking. Crossing your surrounds higher sends their bass to the sub where it belongs. It's got nothing to do with ego. Your ego would be bruised worse if you weren't getting the best possible sound from your system!

Yes, well... the internet is known to be an extremely reliable source of information . But this is not the case here. MultEQ finds the -3 dB rolloff point of each speaker and passes that number to the bass management system that is implemented by the manufacturer. They then decide what to do with that information. They also apply the crossover filters completely outside of MultEQ.



Anything you set before running MultEQ is ignored when you run it. They were either set to Large or had a crossover at 40. You can't have a crossover if your speaker was set to Large. What I think you mean is that you manually changed it to Small and used the crossover frequency that showed up in the advanced menu. Denon is very nice about showing the frequency that MultEQ found as the first choice in that menu.


The Pro software does search beyond the -3 dB point and finds the frequency at which the blend between satellite and sub is the flattest. The built-in version of MultEQ finds the -3 dB point and reports that as there is not enough computing power in the DSP chip to do the more advanced calculations. That is one of the benefits of the Pro app.


We recommend having an installer that has attended the Audyssey training perform the Pro calibration. You can look for one by entering your zip code here:

After having completed the tests more times than I can count, I had one final run through tonight combining every tip I had read, including mic placement, sub placement, running the test late at night to reduce the amount of noise generated from a nearby road, unplugging the fridge and temporarily shutting off the air conditioning, moving the mic as many times as the test would allow etc, etc etc. The results are in and they are nothing short of amazing. My system sounds absolutely fantastic, particularly in the lower register. The bass is now tight, powerful and beautifully integrated with my other speakers. For a complete audio novice this program has been a godsend. I'm blown away.
Thank you everyone for taking the time to reply!

Woow what a difference usinge the MultEQ Pro Software and the Audyssey Sound Equalizer Balanced instead of the internal MultEQ on my European Denon AVP-A1HD. More details is the easiest way to describe the difference.
Is to bad that Denon owners in Europe doesn`t get to
have an installer use the MultEQ Pro on their equipment.


1 Question though Chris.
In my Speaker setup are:
Front: *Focal Utopia Alto Be
Center: Focal Center Utopia Be
Subwoofer: 1 X Focal Sub Utopia Be
Sides: 2 X Focal Electra SR 1000Be bipole
Back: 2 X Focal Electra SR 1000Be bipole

Frequency Response (+ or -3dB) http://www.focal.tm.fr/

Front: 30Hz - 40Khz Low Frequency point: 25Hz
Center: 45Hz - 40Khz Low Frequency point: 35Hz
Subwoofer: 20Hz - 160Hz Low Frequency point: 16Hz
Sides: 72Hz - 40Khz Low Frequency point: 59Hz
Back: 72Hz - 40Khz Low Frequency point: 59Hz

MultEQ Pro software result after 8 Meassurments:
Front: Large (Inverted)
Center:Large (Inverted)
Subwoofer:N/A (Inverted??)
Sides:50Hz
Back:40Hz

Detection Results after changing the crossovers


I have now set all to Small and 80Hz crossover and LFE to 120Hz
Or will it be better just to transfer the MultEQ Pro result?

PerS

With this setup isn't the Audyssey software free to recommend any speaker size or crossover (i.e. it's no longer the pre/pro manufacturer's software (Denon in this case) that does this?).

So why recommend front and center as large in this case?

I'm not sure that they "need" to be made, but 6 months or so ago there was some discussion about having the sound "graze" the mic capsule. I forget if it only applies to the Onkyo-supplied mic, but having the mic oriented so that it is perpendicular to the line to the speaker was said to have produced a more accurate measurement.

I might have taken that too literally, but I had one orientation for the LCR speakers, another for the side surround, one for both of my co-located rear surrounds, another for the other side surround speaker and yet another for the sub.

Here is my original post. If you read the page or two before it and a handful of pages after it, you will better understand. This was somewhat controversial, but I obtained - on the first try - positively stunning results. Before using Audyssey, I was a skeptic at best. Maybe even a detractor.
