"Official" Audyssey thread (FAQ in post #1) - Page 1172

Don't forget, my Integra DHc 9.9 came with the non H model mic. The Integra came out in 2009 I believe. It could be a few hundred mics, but statistically that seems pretty unlikely.

Lets assume that 2.5 % of Onkyo users read AVS forum. Lets assume that 50% of the Onkyo users on the forum are aware of this issue, and that 25% of those aware checked their mics. Lets also assume we have 10 wrong mic's here on the forum.

If the incorrectly shipped mic's made their way to Onkyo users in a random pattern (meaning AVS users who own Onkyo and that checked their mic's weren't more or less likely to get the wrong mic)....we can then take a stab at it:

500, 000 units * .025 = 12, 500

12, 500 users on forum * .5 * .25 = 1, 563

1,563 mic's checked and 10 wrong mics

10/1,563= .0064= 6.4% of the mics are wrong

500, 000 units *.0064 = 3200 incorrect mics out there in the world


This is purely hypothetical, but I think the point is that IF we really have ten wrong mic's that have been posted about by members, the odds that there are only a few hundred are pretty low.

My guess is that ONKYO and INTEGRA are full of it. Just a guess. But maybe it was only a few hundred, and we here on AVS got more than our statistically predicted amount.

I bought my Integra DHC 9.9 here in Sweden.

I am designing a HT with 11.2 surround situated in a multipurpose room in our new house build. I have tried to avoid the use of an AT screen because I read that even a good material mutes the high frequencies by some 2 dB. All speakers except the in-ceiling Heights will have the same tweeters and midwoofers. I am more worried about the A than the V in AV. But a grand screen would be sweet!

Will Audyssey (MultEQ-32) compensate for the loss in the high frequencies of the LCR behind the AT screen?

BTW, any news about the Marantz AV-8005?

I think the answer is yes.
Just as you can get a boost from off-axis, etc. reasons.

Audyssey MultEQ (of any flavor) will measure your speakers response and attempt to match it to the reference "target curve". It doesn't matter if they are behind a screen, it will try and make the final output match that target.

So in other words: yes

If what Onkyo is telling you is true....and if what chris says that each microphone is tested by Audyssey to see if it meet specs, then choose: a)Audyssey is checking the microphones in Malaysia, b)Onkyo is buying replacement microphones that are not tested, or c) the person you spoke to had no clue where the microphone comes from.

Experience (and hope) tells me that C will probably turn out to be the correct answer....

This is a fabulous benefit for me and everyone else with an AT screen. The Ranes all went on eBay within a week of my first Audyssey pre/pro. I'm talking "woven" here. Nothing could compensate correctly for the microperf Stewart I had.

Jeff

All three could be true!

Great info, thanks guys!

Jeff thanks for posting this link. This was the post I had in mind, but I misremembered. Glad somebosy around here knows what's going on.

FWIW, for the good of the order, I put a disclaimer on my prior post just to avoid creating more confusion than necessary.

I just received this in an email reply from Onkyo support this afternoon:

"Thank You for contacting Onkyo USA Product Support.

Due to the holidays we are experiencing a heavy volume of inquiries. We apologize for the delay in responding. Thank you for your patience.

We have shipped a replacement setup mic to you. The model number of the setup mic is ACM1H. We apologize for any inconvenience.

Thank you"

I have my original microphone sitting in a bubble envelope ready to ship back to California, but with this news and Chris stating that he requires no more microphones for testing purposes, I guess I'll be keeping it.

my room is wide but soo are my mains placement soo I go heights & it has a real impact on the sound stage adds more detail & heightens it (Duhh)

Need to clarify: Audyssey manufactures the mics in China. We designed every aspect of the mic and also designed an assembly line test procedure that uses MultEQ in a special box to test each mic. The mics are then shipped to our AVR customers who order them and package them in with their products.

Chris,

Have you considered stamping the model number of the mic on the base? None of the three mics I have are identified by anything other than the word "Audyssey" and, in the case of the two Denon mics, the Denon part number. Only the AS-EQ1 mic has "ACM1" on the box.

Or perhaps there is a reason not to?

Jerry

Hi Chris,

I think it's not just Audyssey, but nowadays everyone manufactures everything in China! Just kidding! Although a friend of mine lately told me, believe it or not, if a product does not bear the sign "Made in China" it must be fake!

On a serious note, and in order to make everyone settled the world over on this mic issue, ...would there be a possibility to work out a quick and downloadable firmware, let's call it a "testware", with which we could all get down to the bottom of this issue? This testware would require pluging in the mic bundled with our AVR, hit "test" and bingo it would say: "You have the proper mic with the proper cal file", or "You have a mic or a cal file that do not match each other". No proprietary info would leak, just a test we could all run in an instant and verify what we have. Onkyo, Denon, Marantz, NAD owners, etc... All...

Just thinking loud, coz, you know, the devil never sleeps!!

Appreciate your utmost efforts to the brim, as always.

Will the SVS AS-EQ1 or the Audyssey Sub EQ still have double the resolution of the Audyssey Sub EQ and Audyseey MultiEQ XT32 found in the Denon 4311? Or is that a thing of the past now and the Denon has more resolution then the SVS / Audyssey Sub EQ?

They all (AS-EQ1, SubEQ, and XT32) provide 512x resolution for everything they EQ.

Sweet. Denon 4311 here I come. Also Counsil, do you have an additional external SUB EQ unit? If so, why? (I assume the 8 Sub Woofers you have)

Hi Feri,
Making a mic test rig is extremely difficult and would be impossible to reproduce as a consumer box. It's a good thought, but not feasible. Much easier to replace any Onkyo mics that are labeled ACM-1 on the box and Onkyo is working on a way to make that happen. No other AVR licensees are affected by this issue.

Hi Jerry,

We did not at the time because the ACM-1 was being phased out and being replaced by the ACM-1H. In hindsight...

Is there any way that I can purchase Audyssey Pro as a consumer rather than going through a professional installer?

Actually, yes. I am still using my Audyssey Sub Equalizer. I have tried removing it but my system sounds better with it. I'm not sure why as XT32 (SubEQ HT) alone should provide similar results. Maybe it's the double EQ'ing that I used to b!@#$ about.

I also really like the level-matching screen that MultEQ Pro utilizes when calibrating the Audyssey Sub Equalizer. I wish Audyssey would add this logic to the level-matching screen for the Denon 4311 (in MultEQ Pro anyway as Chris has already explained that AVRs don't have the required horsepower).

Are you listening Chris? If so, I would also like the Before/After graphs for the sub to extend to 10Hz like the graphs do for the Audyssey Sub Equalizer.

Yes. Contact Audyssey directly at installer@audyssey.com

Thanks!

I'm still wondering if the ACM1 box contained an ACM1H mic?

I'm wondering if I recycled the box my AVR (Onkyo 607) and mic came in, how can I know if I have the correct mic? Would the sound be off that much that it would be obvious?

I swept 27 frequencies from 25Hz to 10KHz using an RS meter and a Test CD. The freqs. were within 3 db of each other. The total range was within 10db start to finish. Is this good or bad?

Sorry, I mis-read or misunderstood. I have deleted my erroneous information. Couldn't, of course, delete them in the posts of other members.

I seem to be guilty of the thing that I cranked about earlier .. exaggerating and making things worse.

Jeff

Impossible to know. Sine waves and an SPL meter in one position are two of the most inaccurate ways to measure frequency response.

Just to be clear (since I fell way behind this thread), the mic issue started in 2008 and therefor should not be a problem with the x05 receivers (made in 2007)? I'm 100% positive I did not keep the box the mic came in (I don't even remember a box).

Thanks.

This was with a 1/3 octave warble tone. Moving the mic around seemed pretty stable. Thanks to Audyssey, it is way better than going direct.
