Now if you listen at reference level then that goes out the window.

Can't think of DynEQ as a dynamic house curve, coz DynEQ has a somewhat different purpose, while AFAIK a house curve does not need to be dynamic.. A house curve is supposed to have a HF roll-off regardless of SPL, see how it developed from the X-curve. Meantime, DynEQ is supposed to take care of the characteristics of our ears where perception of frequencies depend on SPL. The softer the SPL the more our ears loose the ability to hear low and high frequencies. Really nothing to do with a house curve at all. A house curve (like Audyssey target) should be used for movies, while Audyssey flat is recommended for music. YMMV.

Yep, there are two schools of thought.  One, you need a fixed house curve for all content no matter what.  The other, you only need the house curve because you listen and a volume other than what the content was mixed at.  So to me they are the same, both going about the same thing (improved sound in your room) but looking at it differently.

 

But yes, the Audyssey reference curve is part of the curve and even the high freq roll-off changes with DynEQ.  And some prefer the flat curve for music.  So lots of options to achieve the sound you prefer in your room.

Not exactly. More than one study on psychoacoustics has indicated that measurably flat is not necessarily perceptually flat. What IS agreed upon is that a 'smooth' frequency response is best, but folks tend to assess a measured flat frequency response to be 'thin' sounding. The testing that Harman has conducted (among other studies) indicates that most people tend to prefer a descending response, meaning that there is a 'slope' with SPL's gradually declining as frequency response increases. This is what most people hear as 'perceptually' flat.

Coincidentally (or perhaps not coincidentally), speakers that measure pretty flat in an anechoic chamber tend to naturally end up with this sloping response in normal sized rooms due to room gain (and that room gain tends to affect the lower frequencies more).

While DEQ's purpose is to correct for the differences in average human hearing sensitivities(our hearing being less sensitive to the lowest and highest octaves), with the regular Audyssey curve + DEQ, the net result IS actually a house curve, as DEQ boosts the lowest octaves, but tends to maintain the 'Audyssey curve' rolloff above 10kHz. The result looks a lot like the 'Harman Listener testing Preferred Curve' with a smooth response that declines in SPL as frequency rises.

As far as a flat frequency response being the optimal selection for music, that is actually dependent on the room and system setup. Most folks find that in normal sized rooms, with lots of bare walls, this may be a little too 'bright' sounding. Regular sized rooms with a decent amount of acoustic absorption (be it from acoustic treatment panels or due to lots of large soft objects like heavy drapes etc.) tend to not have the same problem as they naturally absorb a lot of the high frequencies. It's about the Sound Power Response at the listener's ears, which is due to both the direct radiated sound PLUS the reflected sound. In some rooms. The sum total may be a bit much due to a more reflective room (and this is also affected by the off-axis dispersion characteristics of the speakers and their placement in the room). In other rooms, this is not a problem, so no, unfortunately, 'Regular Audyssey curve for movies', 'Audyssey Flat for music' is NOT a one-size fits all recommendation. And, in addition, as has already been mentioned, the target curves may not be the best in rooms that are significantly outside the dimensions of the rooms that were used for developing the original algorithms, hence the Pro-kit with its user selectable set of target curves with differing high frequency rollofs for rooms of differing sizes + additional editability.

I decided to pull out old Rat Shack SPL meter. All channels were within 0.5db of each other except the sub. Audyssey set it at -7.0. In order to even out the sub with others I had to increase gain of sub to approximately 0.0. Does this sound right?? Leave it at Audyssey setting (which does sound bass weak) or put gain at level that Rat Shack SPL says it needs to be to be level with other channels?

New to home theater here, just bought a AVR-1612 and had a quick question.

Is adjusting the subwoofer location still critical to getting the best sound quality or does Audyssey compensate for the location of the sub no matter what? If I go through the auto-setup to eq the sub at different locations, will the sub still sound the same since Audyssey is ultimately correcting to flat line the eq regardless of location. Or, will I receive a smoother bass at different locations depending on the dimensions and interaction the sub has with the room. Thanks

Audy can help but still best to find good placement in the room

So at the Trim set to -7 its not 75dB according to the SPL meter? Are you adjusting the knob on the sub or the receiver?

Also if you are going to run audy again, set the Trim on the receiver to 0.0 than use the spl meter to set it to 75dB (using the knob on the sub)

Correct. Not touching the knob on the sub. Adjusting the trim on the receiver to get SPL from sub to match all other channels.

Just curious What it matter what I set the triml on The receiver for any channel before running Audyssey? Isn't it going to reset all the levels again when I run Audyssey?

RS SPL meters are notoriously bad for measuring subwoofer level.  I would say leave it at the Audyssey recommended level but for me that was about 5db too hot.  :)  I was able to use OmniMic and RTA to get the level correct, but without any of those tools I'd trust Audyssey over the RS meter.  But you can always bump up the level to taste.

 

Edit:  Also, if you are using receiver test tones to measure level, those may not be passing through the Audyssey filtering so those levels would be off some.

Thanks. I like my bass a little hotter (I had gain in sub halfway up and trim level at +5 with old sub. Not gain is at 20% with trim at -6).

Finally. I am going to try to not any more Audyssey questions until I re-run it with tweaked mic positions as recommended by others. Hopefully I can do this this Friday or Saturday.

The Rat Shack meter is notoriously bad at the bass end of the spectrum - I would trust Audyssey's more sophisticated methods personally. 7dB is a huge difference, so did it sound very much lacking in bass before you raised the level by 7dB? Does it now sound 'right' to you, and flat? If you play some bass-heavy music (anything by Stanley Clarke is what I usually use), does the bass guitar sound right to you, with no notes overemphasised and none 'missing'? Or do you hear some notes far more prominently than others?  Does it sound 'fat' or bloated or lean, rhythmic and musical?

 

The RS meter is good for setting comparative levels between speakers (other than the sub) but no so good at setting absolute levels, so I would treat it with some circumspection.

Audyssey will do a lot to get the in-room response of the sub right, but it can’t work miracles. The best way to proceed is to do a sub crawl, or measure with OmniMic or REW, first and find the best place for the sub in your room. Once you have done that, then run Audyssey and you should get a superb result. There are some room mode problems, such as deep nulls, that Audyssey cannot correct (nor indeed can anything other than physically relocating the sub). In fact, if you have a deep room-induced null, you can raise the power at that frequency by as much as you like, to sub-destroying levels, and the null will still be there. For this reason, Audyssey restricts it's boost to, IIRC, +6dB.

 

Bottom line: yes, you will get smoother bass from some sub locations than others. Pick the best location you and WAF allow and then run Audyssey as the 'icing on the cake'.

Yes - Audyssey ignores all the AVR settings when it does a calibration.

PTG makes a good point there - your AVR test tones bypass Audyssey, so if the latter has made any significant adjustments to levels, then you will be getting a distorted impression of SPL anyway. You ideally need a test disc for the noise tone generation, so that you can measure with Audyssey engaged. Personally, I'd follow PTG and trust Audyssey more than the RS meter.

Agree, test disc would be the good solution coz it runs thru Audyssey filters. With the internal test tones, please don't be confused if you see the Audyssey indicators lit on the AVR's display, unfortunately the test tone block is after the Audyssey block in the AVRs. Turning Audyssey On/Off in this cases doesn't count.

Although I agree in regards to trusting the final speaker/sub trim levels after running Audyssey as well as not using the Rat Shack SPL meter for the sub as you suggest, it's important to note that the manual test tone on MTG34's Denon is put out at 75db, and any adjustments that the Denon has made to his speakers/sub trim levels after running Audyssey would also be applied when using the manual test tone (ie. if the sub is set to -7db after Audyssey, then the sub test tone is also attenuated by 7db).

Yep, but I don't want to drink from a single source. I want to drink from multiple sources and have them all taste 'descent'.

As others keep pointing out here, TV broadcast audio is just ALL over the place in terms of quality and accuracy. I've personally seen some programs with the surround channels coming from the center channel or one of the front channels just not there at all. It was suggested if you feel Audyssey is doing something incorrect to the audio in TV programs just disable it with a few button pushes on your remote and see if the program sounds any better. If it doesn't then you KNOW it's the broadcast and not your system. Again from personal experience I've never found TV broadcast audio to ALL "taste decent". biggrin.gif

Do the subwoofer crawl. Place the sub right at the LP and then do the crawl by ear or using an SPL. The area that gives you the smoothest responce is were you place the sub. After that set the sub to the Audyssey guidelines and run Audyssey set up.

Is it ok if I put my sub directly on my couch LP, there's no way I can move the couch.

And if I'm using an SPL, what am I looking? Does the loudest reading = the best place for the sub?

I put mine on the couch facing upward but this would not work if there is a port on the back. Low frequencies spread out very well as they leave the subwoofer cone and port(s), so the direction the sub faces is not critical. Ideally it would be at ear level. Having mine face up in my seat is the closest I've gotten to that.

You are not looking for the loudest reading. You are looking for smooth response across the sub frequency range. If you find a suitable location where the sound power level (SPL) varies little from 20 to 80 Hz, you've found a good sub location. If you put the sub there you will measure the same response at the location the sub was sitting during the test.

And then comes the next practical question: what test signal to play during the crawl? Most probably a 20-80 Hz band limited pink noise would be suitable. But how? Download from the Net? Burn to CD? Play via laptop? Where can one find the proper test signal? Recommendations please!smile.gif

I've read that some people use a 40 Hz test signal that they play on repeat. Here's an mp3 file which I put on my iphone, put on repeat and plugged into my denon to get a constant 40 Hz sine wave.

Sorry, I should have mentioned that. You need a source that will sweep from 20 Hz up to 80 or 100 Hz. I use a CD from Stryke. I have seen mp3 files on the internet. I think there are even software programs that will do this. I haven't looked in some years; there's probably more out there now, maybe on a DIY speaker site.

If you don't find a source that will sweep smoothly from 20 to 100 Hz, one that steps up in about 5 Hz increments or less will work.

Once you have a source, put your mic (if you have an SPL meter) or head in the candidate sub location and measure or listen to the SPL as the frequency rises from 20 to 100 Hz. Look for a location that has the smoothest response, hopefully with amplitude excursions of no more than about 5db, 10 db maximum. If doing this by ear It will be hard to judge how smooth the response is, but if you don't hear any obvious peaks or dips in the volume, you have found a good place to put the sub. If you do this test in several locations you will likely find some bad ones and those will tell you when you've found a good one.

This seems like a lot of work, but it's pretty rare to hear someone say it wasn't worth it.

These are adjustments per input that let you equalize the sound level at the speakers so that it is roughly the same for all of your inputs. Setting these prevents you from scaring people with a blast of high SPL when you switch from one input to another or boot the receiver with it set to a different input. I.e., you can switch from a DVD to DVR to TV to a music source without having the volume fall or rise substantially. I still need to adjust the volume a bit when moving to a different input, but at least my inputs are all within about plus or minus 5 db, i.e., at least near normal listening level.

You might try this site to see if they have what you want. http://www.audiocheck.net/ There are some you can set up the way you want and then download. Or at least that's what I recall from the past.
