"Official" Audyssey thread (FAQ in post #1) - Page 1141

Hi Chris,

Your Audyssey products web page may have some errors.

The Onkyo PR-SC5508 preamplifier has MultEQ XT32, but it is not listed on the web page. It does show it having Sub EQ HT.

The Integra DHC-80.2, which is virtually identical to the 5508, does not list the Sub EQ HT feature.

Larry

The answer is no. Gear with "less" than MultEQ XT 32 could have Sub EQ HT technically-speaking, but they don't. And I seriously doubt that it will be added retrospectively to anything.

Thanks Larry,
I have pointed these out to the web team and they will get to them next week.

Job, hah! Try teaching undergraduates for one semester. Then you'll know what patience really means

Correct. But Sub EQ HT doesn't require XT32. It can work with any version of MultEQ should a licensee decide to use it. Hint, hint...



True, sort of. Phase is a misused term because phase actually depends on frequency. Aligns the subwoofers "in time" is a better way to describe what's going on.


Yes you can get them "in time" by doing what you said.



Agreed.



It will adjust the time relationship.

Agreed. Phase align is a tricky term. An allpass filter that aligns group delay may be useful, but honestly I'm not even sure what "phase align" means.

Now what is the deal with this Audyssey MultEQ XT Pro vs Audyssey MultEQ XT 32? I keep seeing this "I'm gonna wait until 32 arrives before I buy" in some other threads.

This will be my 1st AV pre/amp so I really don't know much about it, thanks.

I am looking at the Marantz AV7005 and it has the XT I believe.

Chris, is this true? And if Jeff is correct I feel that I have been wronged!

This has been very confusing and I've had a difficult time getting to the truth of the matter

As much as I love the Audyssey capability on my Integra DTR-80.1 I'm disappointed that it doesn't have the Sub EQ HT function -

ESPECIALLY SINCE THE AUDYSSEY PRODUCTS PAGE SPECIFICALLY STATES THAT THIS FEATURE IS INCLUDED IN THIS PARTICULAR AVR!

I did my best to perform what might be referred to as "due diligence" when researching my purchase and finally relied on the Audyssey Products Page as the ultimate authority on which Audyssey features were included on the various brands and models of components that feature Audyssey Room Correction.

NOW I FIND OUT THAT I SPENT MY MONEY FOR SOMETHING THAT I WAS LED TO BELIEVE I WOULD GET BUT WAS SHORTCHANGED!

At this point it appears to me that the mistake lies at Audyssey's feet. Now the question remains - is Audyssey going to take ownership of it and do the right thing?

What say you, Chris?

A disillusioned Audyssey fan,

No. As I have said several times Sub EQ HT has nothing to do with XT 32. In fact, it appeared in earlier models including yours but did not receive any marketing mention. Have you used Audyssey on your Integra? I'm surprised that you didn't notice the Sub EQ HT functionality of pinging each sub separately and then together as one.

Chris,

I'm glad to hear that my 80.1 is equipped with Sub EQ HT and apologize for getting overly excited after reading Jeff's response to my question.

To say that I'm relieved would be an understatement!

I very recently installed a second Velodyne sub and re-did the Audyssey setup with this change. I distinctly remember noticing both subs pinging separately. I heard them and also watched it happen on the GUI. However, I don't remember the Audyssey setup pinging both subs together as one before finishing the setup, calculating and then storing it. And that's what got me thinking. Perhaps I didn't notice it pinging both subs together and I'm just overthinking the whole thing.

Would it be correct for me to ASS-U-ME (I hate that word) that because Audyssey did, in fact, ping both subs separately and then continued to successfully complete the installation that it MUST have pinged both subs together at the end and I should stop worrying about it? I have no complaints with the SQ and I'm really not looking for any problems, just wanted to make sure that Audyssey's doing what it's supposed to do.

Thanks for your patience,
SB

But who will edit the editors???

I have the Integra DHC 80.2 and a Definitive Technology Trinity subwoofer. In the THX settings of the 80.2 it asks whether the sub is THX certified. The Trinity does not identify itself as THX certified but according to the specs it goes down to 16Hz. Should I be choosing the THX "Yes" box for this sub in the THX set-up menu of the 80.2 when I run Audyssey? Does it even matter what setting this is on when running Audyssey? Right now I do have it checked yes, but have to also set the Gain to "on" after running Audyssey because it just sounds too boomy.

Hi,

If you are referring to Boundary Gain Compensation, these remarks from Chris may be relevant.

Larry

It should happen on the first round of chirps. It pings each sub separately and calculates distance and level for each, then it continues by pinging them together to calculate the room correction filter.

Summing up, that was set the sub to yes for THX and turn "GAIN" off.

IIRC, a THX sub is flat in room to 20Hz and is able to play 105dB. Here is a reference - http://www.thx.com/consumer/home-ent...fied-speakers/

Of course, the bigger the room the more "sub" is needed to produce the SPL.


Jeff

Hi Jeff,

Of course our references haven't helped answer the original poster's main complaint that Audyssey calibration sounds too boomy to him, and BGC applied after calibration seems to help.

Larry

Julian Assange?

True, Larry, but it would probably be better to investigate his boomy complaint than to apply a one-size-fits-all solution after the Audyssey calibration.

Jeff

Jeff and Larry thanks for your replies!

His ability to delete is questionable, and his insertions are alleged dangerous.

Hi Jeff,

That was my point.

Perhaps if bslep further describes his setup and locations of his subwoofer, mains, etc., the folks here might be able to provide some suggestions to obviate the need for BGC.

Larry

Chris,

Tweeters are ok

I have a PA-120 sub and the crossover dial on the back goes from 40Hz to 200Hz. So, before I perform the Audyssey 2EQ calibration I should set the dial to max: 200Hz? And for my receiver's "LPF of LFE" setting it should be set to 120Hz?

After calibration is done should I leave them both at that?

I already did the calibration once but had my sub set to 120Hz on accident, because I confused it with something else (AVR's "LPF of LFE"), so I am trying to get clarification here. Thanks

You are correct on all counts.

One more thing-if your sub has a LFE unfiltered or filter bypass input (some way to bypass or to turn the filter off completely), use it so the dial has no effect. If it was in effect you will off course need to repeat the autosetup once you have set the sub correctly.

Anyone?

Have you looked at Audyssey's website and read about the different "flavors" of their room correction technology?

1. MultEQ XT32 increases resolution by 32x over MultEQ XT (resolutions). Read the announcement here: http://www.twice.com/article/455011-...hp?rssid=20310, or the Audyssey write-up here: http://www.audyssey.com/technology/multeq.html

2. MultEQ XT32 also includes Sub EQ HT, which allows the distances for two subs to be set independently, and then calibrated as one.

These two features makes XT32 a significant improvement over the previous XT technology.

Edit: Sorry, Pepar, answering at the same time....

Really? Wow!
