What test signal are you using? The reason I ask is that there are some DVDs with test signals that were authored without properly setting the dialnorm level and thus could result in a 4 dB difference. Hopefully you are using the internal narrowband test noise of the receiver and you are reasonably sure that your meter is properly calibrated and set to C-weighting, Slow.

Chris, did you just mention the word "Calibrated" to his reference of having a Ratshack SPL Meter? Was good for giggles.

Audyssey NEWBIE HERE...
Before I get my new pre/pro, I would like to know more about the calibration for up to 6 listening positions....will calibrating for each of the seats "improve" my overall results? I have two rows; 3 chairs in front, 2 in back, and then a couch off to the side. If I calibrate for the couch off to the side, will this negatively affect the front row (where I do most of my movie watching)? Thanks in advance...

I have using the internal signal from the onkyo 706 i change speaker configuration so i will recalibrate and retest

Ignore the couch of to the side and concentrate your measurements around the main listening position, as measurements outside of the imaginary parallel lines from your L/R speakers will give less than optimal results. Don't think of it as one measurement per seat but rather a series of measurements for the room.

For simplicity sake however I will refer to seats for measurement locations.
1st measurement location in the centermost seat or primary seating location, then follow up with 1 measurement on either side 2 behind and one about 2 feet in front of the 1st measurement point to create a pentagon shaped pattern with the primary or 1st measurement point in the center. The one possible change to this pattern would be to invert the pentagon shape with only 1 measurement point behind the primary and 2 in front of it if the back row of seating is close to the back wall.

Oouuh. Some people already think Audyssey is magic, and now we're drawing pentagons on the floor?

thanks for the quick reply, but it sounds a bit confusing without seeing my theater. Here is a picture of my theater and let me know where I should calibrate for the 6 positions...MANY THANKS!

Yeah if you have the PRO kit then you can draw the star shape with the 32 points.

1st measurement in front row center seat, then 2nd & 3rd in each of the other seats in the front row. 4th measurement about 2 feet in front of the Right armrest of the leftmost seat in the front row. 5th measurement about 2 feet in front of the Left armrest of the rightmost seat in the front row. 6th measurement between the 2 seats of the back row. This will provide the greatest overall room correction for your setup.

Thanks a lot for helping me out with the purchase of the Audyssey Pro kit. I have been slowly using the kit and trying to get used to the improvements it makes. I love its flexibility, the ability to save microphone readings, and its calibrated microphone.

So far, I have one critical observation. My front speakers are identified by my Denon 3808 as Large and then the Pro software provides 3 suggested crossovers: (1) 60 hz, (2) 40 hz and (3) 80 hz. While 60 hz is the preferred crossover, I have noticed that the bass sounds better at a crossover of 80 hz (basically a tighter sound, less ringing). I think that the reason is that MultEQ provides more filters for the subwoofer than the main speakers and the difference is more glaring in my system because I am using the Pro kit in conjunction with the SVS AS-EQ1 which, with its latest firmware version, has 4x the number of subwoofer filters, as compared to MultEQ XT. I guess it also helps that I have 4 subs. Would it be correct to say that while 60 hz may be a smoother crossover point, the overall sound may be improved with a higher crossover because of the greater number of filters for the subwoofer(s)?

There is no need to modify the software. Just pick 80 Hz in the software and then after you are finished go into the manual settings and raise the crossover to any frequency you want to experiment with.

Chris, my first Pro calibration resulted in the L&R being "detected" as LARGE. I knew to pull down the menu to select a crossover, but the next one offered was 60Hz. Second was 70Hz. NOT third was 80Hz; I believe it was 100Hz ... 80Hz was fifth or sixth.

It is my understanding that MultEQ Pro considers the different crossover points and offers alternates in descending order of ... what was the phrase .. recommendation scores. How much should the operator inject their preferences into the process? Should I have selected 70Hz, or even 100Hz as a crossover for the L&R? FWIW, MultEQ XT setup yielded a LARGE determination for them as well.

Thanks,
Jeff

Thanks CCDC, although I had to read that about 3 times before my lazy brain could figure it out! Thanks!

That's right. The order of recommendations will be different depending on what MultEQ measures in that room with that particular speaker/sub combination. Unfortunately, to comply with the requirements of the various manufacturers on Large vs Small we still have to use 40 Hz as the determination for Large and so you will see the software recommend Large when that happens. We recommend never setting any speaker to Large if there is a subwoofer in the system, but that will (for now) have to be set manually.

Thanks, Chris. It sounds great, but should I have bumped it up from the first choice, 60Hz, to a higher one? Seventy Hertz was the next recommendation.

Does the software consider the difficulty of correcting room modes that might result from mains reproducing frequencies that *could* be reproduced by the sub channel?

This question is not directly related to Audyssey, but perhaps you guys can help me. I know audyssey does not set the ' low-pass filter for LFE' in my Integra DHC 9.9. My question is, where should I set it? Can you explain the purpose of this setting? I don't think it affects the bass management crossover between my sub and mains, but what is that for?

LFE is the .1 channel. Set the LFE LPF to 120 hz. That is the upper limit of the LFE channel. This is addressed in the Audyssey setup guide linked in my signature.

I don't think that 60 Hz or 70 Hz would make that big of a difference...For your system, I would think that either one would be a good choice to balance the tradeoff between sending more content to the sub (for higher res. correction) vs the smoothness of the transition between sat and sub.

Quote:

no, it looks at the blending region between sub and sat and recommends the crossover that minimizes the amplitude and phase variations due to the acoustical summation of two speakers in different parts of the room.

I still see a theme for a TV ad here. Or at least a training video on mic placement.

Many thanks. I knew it had to do with the LFE channel, but did not understand the effect of that setting.

I have saearch online to no avail. Did audyssey change the calibration level of speakers from 75 to 70 on new Onkyo model?

Alain

I just got my Onkyo TX-NR1007 yesterday, ran all 8 positions of Audyssey, and when I check with my SPL meter, all channels read 71dB. I'm not sure which is right either. I know with my old 705 with the cheap puck-shaped mic, the common wisdom was that it wasn't necessarily setting the trims so that 0 = reference level, but it also set all channels about 4dB too low according to my meter.

My understanding is that with the 1007 and the new Audyssey mic, it should be setting the trims so that 0 = reference, but either it's not... or my SPL meter is incorrect by 4dB.

Hi Chris,

I was successfully in running 12 Audyssey Pro measurements without any problems.

The only differences in my prior unsuccessful attempt were:

1. Disconnecting the sources
2. I removed the power from the Onkyo preamplifier then powered up again.
3. I had less Windows applications running along with Audyssey.

Attached are my current results.
Things look better, but I think I need to experiment with subwoofer placement and gain in an attempt to resolve that dip in subwoofer channel response.

Hi Larry,

Good to hear. My money is on #1. We often hear of electrical noise being fed into the system that comes from cable or sat boxes.
post #20487 of 70896
Silly question, I'm sure, but ... : would there be any possibility of a FW update to Audyssey that would allow the DSX 'wide' (or 'height') channels to be output through the SurroundBack channels of a conventional Onkyo or Denon 7.1 AVR? I suppose this would depend on whether the DSX channels were synthesized in Audyssey or in the AVR. And it would be worth a price if it were possible.

You can see where I'm going. I'm very satisfied with my present Onkyo TX-SR805 AVR (after suffering through the effort with the 'dongle' etc. to do the FW upgrades!), but I am intrigued by the DSX wides. The new Onkyo TX-NR1007, e.g., is no better for me than the 805, except that it has DSX; but it seems quite wasteful to have to replace the AVR just for this one feature.

Hi Chris,

When you say electrical noise do you mean in the audio circuit, video circuit or both? My cable box (TiVoHD DVD) is connected via optical. I figured there wouldn't be any electrical noise from the audio over fiber so I didn't disconnect its audio from the preamplifier. I did disconnect the TiVo's video and also the HDMI connections to my Blu-ray and HD DVD players, but the players weren't powered on so I figured that it was unlikely the players contributed to this problem. (The TiVo is never powered off.)

As I mentioned, I plan on working with the subwoofers a bit more, so maybe I can test this issue further when I attempt to run Audyssey Pro again.

I had a similar problem when running the AS EQ1. I had to unplug the power cord to my laptop. The AC/DC converter section of the power cord was causing speaker Hum feedback.
post #20490 of 70896
does anyone have a link to some set up preferences...

front hieght or front width.

i just got a onkyo 707 and i cant decide where or what to do with the extra fronts.

I tried searching with over 600 pages of stuff i havent had much luck finding what im looking for.

any insight would be greatly appreciated
