"Official" Audyssey thread (FAQ in post #1) - Page 495

Any settings you made before running Audyssey setup are ignored. But the LPF on LFE should be set to 120Hz after running setup if is is not. I don't understand why there is even a setting for that.

I recently purchased some surround speakers that are capable of direct firing, bipole and dipole configuration. Do i need to run Audyssey in each configuration to compare results?

Audyssey will EQ/correct them in any radiation pattern. I think the differences in the way they perform will depend on the content. Monopoles produce a more focused surround experience, while dipoles are more diffuse and enveloping.

FWIW, I use mine as dipoles for side surround and monopole for rear surrounds.

Do you need to optimize with Audyssey each time, compare results, and choose your favorite? If this is the case, after running Audessey, if I choose to run in a different mode I would have to recalibrate, and not simply flip the switch.

Perhaps Chris can better address this, but I think there would be filter differences with monopoles than with dipoles. What they differences would be, and whether they would be noticeable is the question. I think that different channel level trim settings would be different; perhaps that might be the only change you need to make when flipping the switch? That seems doable . . .

Jeff,

Thats odd as when I ran Audyssey the first time I set the LFE to 120Hz and it stayed at 120Hz. But when I ran it the second time I set it for 80Hz and it stayed at 80Hz. I just find it strange that one cailbration sets the fronts to full then the second to a 100Hz x-over. Both calibrations were done in the exact (within 1/2" max.) mic stand locations. The sub distance issue concerns me as it leads me to think it is some setting or an issue with the 886.

All sub settings (Outlaw LFM-1) and location are unchanged from when calibrated with both the 805 and 885. From what I have read if the distance is greater than actual that is fine. But if it is less than actual (almost by 1/2) then there is an issue. Thanks for your help.

Bill

that's because Audyssey doesn't set the LPF LFE

OK. Would having the LFE set differently for the two calibrations I did effect the way the fronts are set? After the first calibration (LFE at 120Hz) I changed the setting from Full to 80Hz as I prefer not to run my Sierras full range for HT. But after the second calibration (LFE at 80Hz) the fronts were set to 100Hz.

From what I have read it is OK to raise the speakers x-over setting but it is not recommended to lower it. Any thoughts on the above questions and why the distance setting for the sub is lower than the actual distance? Any thoughts or advice would be appreciated.

Bill

it's totally normal for there to be slight variations in the measured xover frequency with different Audyssey runs. the -3dB point of your fronts is probably right around 80Hz in your room; if Audyssey measures it at, say, 78Hz one time the receiver may set the xover at 80Hz. If the next time, because of slight variations in placement/position of the mic or whatever, it measures at 82Hz, the receiver might choose the next higher option for xover (100Hz).

remember the xover is chosen by the RECEIVER, not Audyssey, based on the measurements Audyssey provides. The -3dB point is calculated based on ALL the measurement points, so even slight variations could lead to slightly different end results.

the LFE setting has nothing to do with it, Audyssey ignores any settings in the receiver when doing the auto setup.

I also thank-you. I have a 3808 and thinking of getting a AS-EQ1.

I have a questions and no matter how hard I try searching though this thread I cant find what I am looking for.

It's probably been asked before but when using Audyssey MultEQ on a Denon AVR-888, and the first thing I did was read over all of Audysseys description of what the product does. How does it smooth response for and entire frequency range when the warble like tones it plays are not full range? From what I can tell those test tones Audyssey uses dont sound like they go as high as 20KHz and don't go as low as 20Hz. So how does it correct the entire range to be a uniform?

They are full range. They are also quicker at going from the lowest frequency to the highest than it can register in your head.

Chris/ or anyone that can help answer this:

I just moved into a new home with a new "theater room".
After setting up the system I ran Audyssey several times with very similar results...

My concern is that Audyssey is setting the crossovers on my RT and LF front speakers to 150Hz. (all other speakers were set to either 60 or 80Hz)
At my other house Audyssey crossed the RT and LF over at 60Hz (I reset them at 80Hz as recommended).
The RT and LF speakers are Infinity towers (RS10) with ported 10 inch woofers (specs. claim 28-20,000 Hz)
The room dimensions and speaker configuration are almost identical (within inches).
The furniture is not the exactly the same but quite similar (leather couches and tables).
The flooring is now carpet instead of laminate.
I tested all the drivers with a sound meter to make sure they didn't get disconnected during the move.

Is this significant change due to room acoustics?
Since I know the speakers can go much lower (as per my old house) can I change the crossovers to 80Hz?
Any ideas will be welcomed.
Thank you
Danny

I think it's your receiver system that does this setting of crossovers, rather than Audyssey. (If they get set wrong, probably you want to set them right -- but I'm just guessing.)

Just received a Marantz Sr5003 and ran the Audessey with all 6 positions. All speakers were detected, speaker distance calculated and speaker levels were adjusted, and all settings were successfully stored but when I go check the results for the EQ all the filters are at 0 for all frequencies. I cant imagine that the room doesnt need ANY adjustments. Has anyone ever experienced an issue like this? Already have an RMA request into Marantz for a replacement.

I would suspect the microphone or the mic's connection at the AVR. A return is definitely the way to go.

Have you selected the mode to display Audyssey?

Pg 40 of your manual:

EQ MODE: There are 4 equalizer modes to choose from:
PRESET G. EQ that allows the user to manually
adjust the equalizer, and AUDYSSEY, FRONT and
AUDYSSEY FLAT that automatically adjust the
equalizer from the measurement results of the AUTO
SETUP feature (see page 30).

FRONT: This mode matches the characteristics of each
speaker to those of the front speakers.

AUDYSSEY FLAT: This mode fl attens the frequency characteristics of
all speakers. It is suited for playback of multichannel
music such as Dolby Digital and DTS.

AUDYSSEY: This mode adjusts the frequency characteristics
of all speakers so as to create the best listening
environment for the sound characteristics of the
listening room.

PRESET: This mode adjusts the graphic equalizer that
was set in PRESET G.EQ ADJ to adjust the
characteristics of each speaker (see page 41).

OFF: The graphic equalizer is not used.

Jim, if that were the case, he would have gotten an error and not have been able to run setup.

Yup, EQ is turned ON but the display only toggles to PRESET or OFF...There are no other options to choose from like AUDESSEY, FRONT or FLAT

That's odd. If there's a thread for your Marantz model, try posting there.

In that case the Audyssey calibration did not complete. You are only seeing the manual calibration with the parametric bands and they all start at 0. Did you save the MultEQ calibration when it finished?

Hey Chris, I had a question yesterday, maybe you can help. I recently purchased surround speakers that can work as direct fire, bipole and dipole....in order to compare these settings, do you need to run Audyssey 3 times and select the best result? If so, I would therefore assume that if I choose 1 result and decide to switch it to later (there is a switch on the speaker), I would have to redo the Audyssey calibration.

Thanks for your reply its really appreciated, one other question is do any of the newer product actually show the before and after graphs of the response?

Thanks for the earlier ideas on my sub issues and distance being shorter. I've moved the subs around, placing the DSP based sub "nearfield" to the seating area along the left wall since it was coming up with the huge 27ft distance on its own, and left the 2 none-DSP subs up front spread out next to my mains about 12ft away.

I reran Audyssey again and getting a 9.4 ft distance for the sub, which is below the actual distance of the subs up front by about 3 ft., and figuring in the DSP delay of the other sub, it is probably about right since it is much closer.

Not sure if it is recommended to change this setting to be more physically correct? I've run Audyssey calculations on the subs independently and always shorter than actual.

Another strange thing this last go around, normally it says my center is large and 40hz, which I change to small and 80hz. This time it has it set to small and 40hz? I did change it to 80hz, but thought it was funny it was set to Small? Maybe when I reran Audyssey, it did not change the Denon back to defaults, not sure.

Thanks in advance, Randy

Yup I stored it successfully.

Try running Audyssey setup again, but with only two or three mic positions (to save time) and see if your EQ still has no option to display Audyssey. If not, then you'll probably using that RMA. Before that, though, I suggest that you post your issue in your AVR's thread.

Chris?

This is only available in the MultEQ Pro software that runs on the PC and can calibrate products that are enabled for MultEQ Pro. The primitive OSD graphics do not lend themselves to showing fancy graphs.

Yes, there is currently not enough memory provided to us in AVRs that would allow us to store multiple calibrations. So, you would have to redo the calibration if you want to revert to a previous condition.

Thanks but I have run Audyssey roughly 3 times with 2-3 mic positions and several times with 6 positions, no luck. Im picking up a replacement unit at their warehouse tomorrow so I can figure it out over the weekend. Crossing my fingers this one works.
