"Official" Audyssey thread (FAQ in post #1) - Page 1102

Yes, it does.

I HAD the upgrade for the 3808 with Dyn EQ btw and it still set my center at -8/9...not the -12 the 3310 and 4311 have.


James

There are several other factors that can be different including the gain of the internal amplifiers, the first mic position, and the sensitivity difference between the two mics. 3 dB is not all that big of a difference...

^ Right. It's just odd to me that the first two AVRs were pretty much identical, then, absolutely nothing changes besides the AVRs and we have at least 4db changes- could be more of course though as -12 is the max cut.


The starting mic position was and is a very specific spot...never varies/d by more than an inch or two.

The identical external amplifier has been used with all four and, my understanding is that the pre amp output of all four AVRs was right around 1.2 V's.


I just wish you could witness what's going on, just so you could have a better understanding from first-hand interaction.


James

Have you checked the levels manually using the internal test tones of the receiver and a SPL meter, set to C-slow, at the first measurement position?

Good point...I plan on doing just that this week.

James

Misspellings and teenybopper e-speak isn't cross generational. It's improper usage.

If you manually adjust channel trims after running XT32 (Onkyo 3008), how do Dynamic EQ & Volume handle that change with regards to reference level?

Chris,

First let me say thanks for the copy of the AES paper,I found it to be a very interesting read into small rooms and room equalization.I also found it interesting that the psychoacoustic smoothing /ERB filter that Audyssey uses is more representative of what the human ear will interpret vs. traditional 1/3 octave smoothing.

I did not realize how much thought went into the installer kit,especially the mic holder and I may have skewed my measurement results by using an after market clip style holder on my last two measurement sessions over the "goose-neck" version that is supplied with the kit.I found when I used the "goose-neck" that the mic would tend to slightly lean in one direction or the other and that having to re-straighten the holder constantly was a little more time consuming,so I decided to use a more(ironically)rigid clip style mic holder with a couple of turns of 1" diameter Velcro tape,similar to the Velcro ties that come with the cables except cut to length from a roll to fit the mic into the clip holder better.

This is the mic holder I used.

Did I make a big mistake by doing this? I remember the earlier kits using a fatter mic(looks just like my behringer ECM8000 that I've used with REW) with a different mic holder.Was that a factor in switching to the current mic and holder set-up?

If you change them all with the same amount of dBs, Audyssey will
know about the trim change and still work properly but you will have
a different "Reference Level". If you up them all with +3dB, you will
have Reference Level with the Volume Knob at -3 instead 0.
But if you adjust them differently, you will mess up Dynamic EQ/Volume.

Quick question folks:
I have a new Integra 80.2. Wanting to do Audyssey Pro calibration on this but the unit has a few bugs that may or not be specific to my unit - waiting on some more testing and giving Integra a chance to do some firmware updates before I possibly do an exchange. If I buy a license, and the unit ends up being replaced by Integra, will Audyssey allow me to port my license to a replacement unit or will I have to buy a new license?

I think a new license.
But, good question.
I was kind of considering selling my Denon 5308CI(A) and getting a 4311CI to play with.

Mike

Not Chris.

The Pro mic holder provides some isolation from the rubber suspension. Did you not get a mic stand and holder with your kit?

Jeff

I'd contact Audyssey directly (or audyssey via PM) and ask.

Jeff

I have an Onkyo 3008 with XT32. I previously had an Onkyo 805 with XT.

My concern is with trim levels. After running XT32 on the 3008, I double-checked levels with my RS SPL meter and the 3008's internal test tones, and most speakers were around 70db on the SPL meter. I also noticed that when watching familiar scenes, I was having to run the volume about 5db higher on the 3008 to reach the same levels I had gotten used to with the 805. In other words, if I watched something at -5 on the 805, I had to go to 0 on the 3008.

This makes me wonder which is actually closer to real "reference". It concerns me because I have watched some movies at -5 or -6 on the 805 and now I wonder if I was actually watching them at reference.

This leads me to think something is off somewhere: 805 or 3008 mic accuracy, 805 or 3008 test tone accuracy, RS SPL meter accuracy, etc.

By the way, I tested with Dynamic EQ both on and off. I don't use Dynamic volume.

Any thoughts would be much appreciated!

^ I believe the same. I exclaimed a few posts back that I'm actually experiencing the phenomenon with DSX engaged.

Mine however is about -10 in my estimation. I typically listened around -10 and now seem to be right at 0 for similar results. These are on BD's that I'm quite familiar with.

I'm going to measure today or tomorrrow to confirm/nullify.

Mine's

Chad T,

I seem to remember this being asked and answered very recently ...

http://www.avsforum.com/avs-vb/showt...8#post19522788

BTW:

My current living arrangement kinda negates me from putting any more holes in the wall for inwalls or mouting any more speakers on-wall, so I considered fabricating stands to place atop my rather large towers for a pair of heights

Now, while I know 45 off center is ideal, will the 30 deg and 3 feet above the mains work out decently for a spell? Again, it's just not practical to wall mount, use in walls , or construct 6' stands at this point.

thanks,

James

well, no, it wasn't.

Chris was (seemingly) under the assumption that I am/was confusing DSX with Dyn EQ and /or VOl.

I am not.

What I am stating is that there is a marked decrease in volume when I engage DSX over straight 5.1 or "PL IIx'd" 5.1 content. Same components. Same media. Same volume value. DYN EQ: OFF DYN VOL: OFF DOL VOL: OFF

That said, I ALSO seem to have seen a general decrease in vol at "x" on the scale when compared with my other (3) Audyssey EQ and XT AVRs.

James

I own the Energy Encore Home theater system. I love them but am forced to relocate the front speakers above the tv instead of under it. Because they are in a bookshelf configuration, I'm unable to use the center channel because of its width (with keeps it from being placed relatively centered above the set). I aquired an extra pair of sattelites thinking one would work as a center channel. However, when calibrating with Audissey (onkyo 705), it reports the crossover frequency as being 100-120hz for the front channels. Clearly the sattelites don't go as deep as the center channel did.

Here's my question, do any of the newer energy sattelites work will with the encores? I'd buy three for the front channels if they're still relatively small (less than 1 foot high)?

Also for you encore owners who use audessey, do you get crossover frequencies that are high too?

Clearly not the right thread, my friend. Try the "speaker" forum and seek out Energy owners there.

James

This would be a warranty exchange - so same model, but different unit, MAC address, etc - I'll PM Audyssey --

Chad T's and part of your issue was ...

.. and that was answered.

Jeff

So apparently I was actually listening to reference level when I had my 805 set to -5 on the volume knob. I actually watch some movies at -5 to -7 in my 18x11.5 listening room and I run subs 3 to 5db hot. I guess reference isn't as loud as I thought it was. And this makes me a bit concerned about my ears.

No.

Again.

My issue re a decrease in volume with DSX engaged was NEVER addressed.

You're speaking about ANOTHER question I had regarding non-matching trim-levels.

Please read my own and the ensuing posts.

And still, Aud hitting a max cut on 1/3 of my speakers in a relatively straight-forward, vanilla config STILL seems odd to me, but I'm not going to beat it into the ground.

James

Clearly there is a mixture of questions here. Some questions are Audyssey, some speakers. Why not just see if someone will answer them? Any of them.

Isn't anybody reading?

IOW, the 805 did not set levels to reference.

Jeff

My reading comprehension is fine, thanks. But I am beginning to question that of others.

AGAIN, my Denon 3808 was XT-equipped with the DYN EQ and DYN VOL upgrade purchased, so that alone doesn't explain the trim differences between my 3310 and a 3808. Both with 1.2 V pre-outs and an identical "adj gain-less" ext amplifier.

My though was perhaps the 3310 "just" having MultEq and/or the mic was accounting for the at LEAST 4db differences.

James

Here, here. No need to get bent out of shape. Actually, I believe you were mis-reading what I wrote. Because what I wrote confirms everything you posted.

In other words, I get the same levels with the 805 at -5 as I do with the 3008 at 0. So when I set the 805 to -5, I am actually listening to reference level (at least that's what I gather from what audyssey wrote).

Same answer as last week.
