I know you were joking, but I'd bet that the course is waaaaay more "computationally demanding" than anything we have seen posted here.

Will the outboard Pro unit properly equalize/integrate two (or more) subs?

Is there something unique/different about the multiple sub routines in the outboard sub only AS-EQ1 unit?

Thanks for you help.

Not sure. It would seem that you can just set the two equal and let Audyssey do the rest.

Can Audyssey be turned on for playback of Compact Discs? I have a PS3 and Onkyo 607 and it turns off when playing CD's.

Hi Bruce,

I assume you mean the Audyssey Sub Equalizer. Yes, it will properly equalize and integrate two subwoofers. The core algorithm is the same as in the AS-EQ1. The Sub Equalizer is intended for the installer market and requires the separate Audyssey Pro installer kit. It can also support two zones (two subs in different rooms).

Hi Myron,

No, we don't support these antiquated two-channel formats Sorry, couldn't resist...
This must be an input setting in the Onkyo for that source that you need to change.

The price has already gone up appx $100 since I posted this (and hit count has roughly doubled). I wonder why?

Apologies for being unclear. I'm asking whether the eight channel Sound Equalizer does as good a job integrating multiple subs in a single room as the AS-EQ1 does?

The Sound Equalizer doesn't yet have the firmware to integrate multiple subs. It is intended for 5.1 + 2.0 or 7.1 systems.

What's your setting on the PS3 for "Audio CD Output Frequency"? The PS3 can upsample CDs to 176.4kHz, which might cause Audyssey to be bypassed on your receiver.

The PS3 gives me two options: (48kHz) and (44.1/88.2/176.4kHz). I had it on the second option (44.1kHz) which I thought was correct, since it is the CD data rate. But Audyssey turns off. I then tried 48kHz and Audyssey stays on. Is there a way to keep Audyssey turned on with the other data rates? I played a few tracks, and it definitely sounds better now with Audyssey turned ON.

It would be nice if I could store multiple correction curves (No dogs, one for each dog, two dogs) as the frequency response changes quite noticably depending on which one is in the room.

So Chris, will this work or will a license key have to be purchased to make it work? Can a license key be purchased separately from the hardware?

As with all Pro Audyssey kits, a license key is required for each device that is calibrated. The license key is tied to the serial number of the device. Also, the software in this kit is from 3 years ago so one would have to purchase v. 3 to be up-to-date with what Audyssey offers today in the installer program.

Hi All,

The Audyssey sub setting is giving me some problems. I was hoping someone here may have solved something similar, or be an expert on this.

My setup:
Integra DTC-9.8
Emotiva MPS-1 running the 7 non-sub channels (those channels calibrate just fine)
Axiom Epic 80-600 7.1 (so that's an Axiom EP600 sub)

EP600:
Connected to DTC-9.8 using XLR cable
Settings = Phase = 0, Trim = Flat, Crossover = Bypassed.

So here's what happens:
- I have the volume on the EP600 set to where it just kicks in to be audible (this is at maybe 10% of the entire range of the volume control - very, very low)
- When I run Audyssey setup, the DTC-9.8 reports -15.0 dB (that's the max on the 9.8)
- If I turn the volume on the EP600 down just a gazillionth of an inch and re-run Audyssey setup, the sub section of the test becomes no longer audible and reports +12 dB (the other extreme)
- If I turn the volume on the EP600 up just a gazillionth of an inch and retest, I get -15.0 dB again.

Possibilities in my brain:
Sub is too much of a beast for this space?
Volume knob isn't functioning properly? (Unlikely - it does go louder and softer through its entire range except for that lowest 10% or so)
Hopefully it's something else that I'm missing. I hope it's just something stupid.

Any ideas on how I can get this thing set at a good, (not -15.0 dB) level?

Thanks!

Nuke

Possible.

FWIW, I had the EP600 and the amp malfunctioned. I returned the amp for an exchange and got the newer amp version. The newer version 'fixed' the issue with the overly sensitive volume control that you describe.

Thanks, man. I'll give Axiom a call tomorrow and see if I might be able to swap that out. Just figuring out a possible culprit for this gives me some hope!

Just curious if the Audyssey concept can (or is being) be applied to larger areas such as concert halls or arenas?

I realize room/structure treatments before designing those are most important, but just curious about the technology and modelling.

Good luck. Not sure how willing they will be to swap out a 'functioning' amp...

After running MultEQ on my Marantz sr6003, the following settings occur: front and center small, surround large (5.1 system), sub LPF/HPF 180!!

My speakers are 5 matched Tannoy 5" dual concentrics with a published frequency response of 80-22K. The sub is a Quad L-ite 10", 300 WRMS, published frequency of response of 25-95hz!!

Can someone shed some light on how, why, and what this means...and maybe what do do?

Thanks,
Bruce

Bruce -

Welcome to AVS.

Have you looked at the post #1 in this thread, especially the FAQ?

Any specific questions?
If your implied question is why does Audyssey not see/suggest full range for your L/R speakers, it is because the sub may handle that area better.

Mike

Where are your mains and how large is your room? If they're out from the wall, or the room is large, then Audyssey got it right.

The Tannoy Arenas are great little speakers, but there's only so much a 5.25" basket, 4" cone driver can do down low before unacceptable levels of distortion set it.

The only thing you can really do, is disable the 176.4kHz output (in the HDMI Audio Setup) from the PS3. The Onkyo doesn't have the horsepower to run Audyssey @ 176.4kHz.

It's unfortunate that this lack of processing power in receivers is breaking an important feature of HDMI where the source device is supposed to be able to determine automatically the best format to send. In the case of PS3 CD output, 176.4kHz without Audyssey is surely worse than 88.2kHz (or even 44.1) with Audyssey. It's not just a problem for Audyssey-enabled receivers either, although some will automatically downsample and keep the selected processing enabled when they run out of processing power, rather than turn off processing.

If I'm running 7.2 any reason to not add an AS-EQ1 downstream from the Sound Equalizer? Or, am I better off simply running the two subs as one mono sub off the Sound Equalizer directly?

Bruce, what are the crossovers for the main speakers (to the sub channel)? The LPF on LFE is not what you seem to think it is, and it *should* be high.

edit: After re-reading I see that the surrounds have no crossovers in which case I would set them to 80Hz. What are LCR crossed at?

further edit: Ignore published specs.

So, after further discussion, "carelessness" probably isn't a fair characterization? But then you referred to the subject of FIR and IIR as a "holy war" so methinks that you are inclined to hyperbole.
