"Official" Audyssey thread (FAQ in post #1) - Page 1987

 

Remember the rule--never lower a crossover that has been set by Audyssey.  So, leaving your surround crossovers at the 110/120Hz values would be appropriate.

WAF? Wife approval factor??

Or Acceptance or Appeal: http://en.wikipedia.org/wiki/Wife_acceptance_factor

Happy wife, happy life. That may or may not be true, but the opposite is *definitely* true!

"If she ain't happy, nobody is happy." Truer words were never spoken, lol.

I hear that! My wife to this day does not like when sub pressurizes her ears. She comments but continues to watch the movie lol!

Typo by someone recently on the "most recent hi-res audio purchases" thread had Sting's "Sacred Love" as "Scared Love." Similar head nodding and agreement ensued.

Pro users always refer to the x-over selections as if they were ranked. AVR selections aren't ranked by Audyssey. So, it seems reasonable to assume that if Audyssey had control of bass management in AVRs, that they would see adding ranked x-over choices as reducing the value of Pro, something most companies don't like to do. Do you think if Audyssey ever got control of AVR bass that they would include the same ranking system as the Pro? That would be cool if it ever happened.

AVRs just choose the next step above the f3 point as determined by Audyssey as far as I know. Is Pro more sophisticated in its determination? Or is it just doing the same thing as an AVR, but presenting it differently?

The x-over doesn't have to be high every time, or most of the time, or a lot of the time, to be annoying. If it happened a small part of the time, say 10% or less, that would do it.

 

That sounds a bit cynical.  I don't think the Pro Kit is a money-maker for Audyssey, it's probably just the opposite.  And when Audyssey recommends a high crossover, I believe that it is because there is an issue, not because the product is flawed. 

 

BTW, I lost the train of thought.  Were you trying to make a point that we could all benefit from?

 

 

No way of knowing what they would do. I suspect they would set the one XO based on the F3 as now.

 

 

 

Pro calculates the XOs and ranks them in order of preference, (based on Audyssey's algorithms and secret sauce I assume). The extra sophistication comes from calculating the filters after a XO has been chosen by the user. With XT32 etc, if you change the XOs manually, the filters do not change - hence the advice never to lower the XO from that suggested. With Pro, you can select higher or lower XOs and the filters will be recalculated accordingly.

 

 

 

Well, we've gone from "Audyssey likes to set the XOs in triple figures" to "1 time in 10 Audyssey might set the XOs high" so that is progress ;)  Has it occurred to you that when Audyssey sets a 100Hz XO, there is a good reason for that?

I just got a new subwoofer (Polk PSW505) and I just redid the Audyssey setup on my Denon 1713. This is a noob question here so forgive me: My speakers are set to small. My front and surround speakers came in at 60hz and my center came in at 120hz. Should I leave them at those levels or change them to 80?

You can leave the crossovers as they are if you like the sound.  Or, you can raise any surround to a higher value, e.g. 80Hz.  However, it is never recommended to lower a crossover value, because Audyssey filters do not extend below the recommend crossover point.

 

Have a l;ook at the Audyssey FAQ linked in my signature for a lot of useful Audyssey info. The FAQ has been specifically designed for those new to Audyssey.  The relavant section to your question is here:

 

c)2.   Why do I often see advice to raise the Crossovers to 80Hz?

I am planning my theater with an equipment room located outside of the theater. How are you guys dealing with receivers located outside of the listening room?
Wireless mic maybe?

Has anyone tried Audyssey XT32 for nearfield speaker correction, like a poor man's DEQX?

If you have in ceiling speakers and use Audyssey how does it measure the distance to the main listening position? Does it measure from tripod to ceiling height or from tripod (MLP) to the actual speakers?

My sub has a low pass nob on the back. the settings can be set from 60-120. Should I leave it in the middle or do it I turn it down? And I should use LFE instead the line in, correct?

Set the knob to the highest setting and and if your referring to the defeat switch set it to OUT.

The microphone can't see either the ceiling or the speakers (or anything else). The system measures the time from when it emits the test tone until the time the sound reaches the microphone to establish distance/delay. Since the sound comes out of the speakers and is captured by the microphone, it's the time from when the speaker makes a sound until that sound reaches the mic that gets measured.

It measures the ceiling with a modified Flux Capacitor.

 

For running Audyssey you mean?  I had the mic cable permanently installed through the wall along with all the other cables. You can also use an extension for the Audyssey mic - see this FAQ answer:

 

d)7.   Can I extend the Audyssey mic cable?

 

There's no way to use any form of wireless mic with Audyssey.

 

f)3.    How do I set the controls on my subwoofer before running MultEQ?

 

JHAz has answered your question comprehensively. I'd just add that Audyssey doesn't measure the distance at all. It measures the delay between the speaker making a noise and the noise arriving at the mic. It can then calculate the distance by using the speed of sound as a known constant (in air).  It is important to measure the delays in order for the sound to arrive at the MLP at the appropriate time, regardless of the speaker it has emanated from - this is important for imaging and clarity and panning of sounds left to right and front to back. If you think of the speaker 'distance' settings as 'delay' settings, it all falls into place. Audyssey only measures the distance once - when it measures the mic at the first position in the calibration (the MLP usually).  So it makes no difference what kind of speakers you have nor where they are located - Audyssey will still work properly. 

 

There is a potential issue with in-ceiling speakers in that the grazing angle of the mic is not what Audyssey might have been expecting. As you will know if you have read the FAQ andor/ the 101 linked in my sig, the Audyssey mic must be used upright, pointing up to the ceiling. This would normally mean that it is at a 90 degree angle to the speakers. With in-ceiling designs the mic will be much closer to 0 degrees angle and this may throw Audyssey off when setting the HF filters. Run Audyssey as normal and see if the resulting sound is pleasing to you. If it is, you are good to go. If not, especially with regard to the HF, report back and we can make some suggestions.

i realize these calculations aren't actually distances but delays.

 

You are in the near field. Not strictly speaking but by the normal standards for the purpose of this conversation you are. Whether you use the Music curve or the Movie curve is largely a matter of taste - try them both and see which, if any, you prefer. The difference between them is explained in this FAQ answer:

 

a)7.   What are the Audyssey 'Movie' and 'Music' curves?

Why would you do this:

If your sub has an 'Auto-on' setting on its power control, remember to turn this OFF before running MultEQ. If not, the sub might fail to 'wake up' when it is first pinged and this will throw off the calibration.

If it's 'off' it won't make any noise!

 

I think the intent was to advise you to turn off the switch that allows the sub to hibernate, I.e. make sure the sub stays on.  

They mean defeat the auto on setting, i.e. force it to stay on. Obviously you don't turn your sub off!

I agree the wording could be improved on that one.

I will attend have attended to it.

As the others have said, the advice is to turn the Auto-on mode to OFF, not the sub itself!  I have amended the wording of that FAQ answer to make it more clear.

I knew that myself however I was thinking of more the 'average joe' coming here and then to your instructions and to follow them 'word for word' - as no doubt someone would. My intent was to call attention to it (it did) to re-word it to reflect to turn the 'auto-mode' to 'on' so it remains 'on' for the calibrations.

I've read your post re: dual subs and I am in the boat of having the Onkyo 818. It has dual-subs but it does not calibrate them separately. I, actually, am confused by the "Y=splitter" info etc. My Subs (identical) have a direct input on them (no need to use red/black). I have them individually plugged into the two subs on the AVR. I calibrate one to 72db (the AVR w/EXT32 first asks to cal the subs to 75) , then shut that one off and do the same for the other.

Are your instructions stating that, for my AVR, I should connect both subs to one Y splitter and only use one sub 'out'?
