In the end, I got a +3.5dB on the LFE trim. AVR is Denon 3312.

Is it normal that Audyssey will do a 2nd round if the 1st round is too soft??

I don't think I can increase the subwoofer volume (on the sub amp plate) because the Antimode will clip during it's own calibration.

 

It is normal for Audyssey to do a second (and a third if necessary) round, but only if it detects high ambient noise when performing the measurement. A second round in no way invalidates the calibration though. A trim of +3.5 is fine.

 

Take a look at these FAQ answers for more information:

 

 

 

b)9.   Why is Audyssey 're-chirping' and raising the level of the test tones, even though my ambient noise is very low?

 

b)10. Why can I barely hear the test tones when Audyssey is calibrating my subwoofer?

 

b)2.   Why is Audyssey reporting 'Ambient Noise Too High'?

Only you can say if it is worth spending the extra, but there is no doubt that XT32 is a significant upgrade over XT (I did that exact upgrade myself FWIW). I heard immediate and obvious benefits to the bass. This was before I treated my room - the difference would, I expect, be more subtle now.

Thanks, that's exactly the type of feedback I was looking for - I guess I was concerned that I was paying for a technology (XT32) that I wouldn't fully utilize as I have no immediate plans (due to WAF) to setup the room with HT requirements as a frist priority. However, it sounds like since I'm not going to do that I stand to benefit even more. Thanks again.

After getting feedback from this and the Denon 4520 thread I think I've just about convinced myself to go with the 4520 over the 3313. However, if I can successfully convince the wife to incorporate height channels (no room for wides), can DSX be applied to two channel sources? This isn't a dealbreaker but I noticed today in this thread that DSX 2 was announced which deals with 2 channel sources. So I guess I was wondering if you take a 2 channel source and apply PLIIx to get 7.1 matrix playback can you then apply DSX to derive height information?

I figure if I'm going to jump on the 4520 bandwagon I'm going to annoy the wife until she stops vetoing the height channels - I'll feel better about my upgrade if I can hook up a couple of extra speakers:).

I am sorry to disagree.  I am not suggesting anything! I am saying that concert halls are made with a lot of wood that's all, and yes I prefer the sound of a concert hall than a cinema.

If I record music in a concert hall, using microphone positions that capature the sound of the hall, then play it back in the same concert hall, the hall sound will fight the recorded hall sound, yielding, likely, a spongy-sounding inarticulate mess. Heck, I don't even use reverb on my guitar amps for the same reason.

Saw a very fine keyboardist using a highly advanced piano program for live performance with a band. He used a setting that recreated a close mic and a more distant mic on a grand piano, and it sounded great where he was playing, 3 feet from his speaker. It was utterly unintelligable in the club because his native sound was so awash in reflections that the club's reflections just killed the direct sound of the piano. Literally sounded out of tune at times. Shame, really.

any of you know if Audyssey Pro in this unit allows for shelving filters or any other type of L/T equivalent?

Specifically I'm looking to see if Audyssey Pro in the Marantz AV8801 has the capabilities of doing any sort of low end improvement via shelving filters or similar approaches...

Yes, DSX (at least the first version) only works on 5.1 source content. But you can use another method (like PLII) to first matrix the stereo signal and then layer DSX on top to generate heights and/or wides. With the 4520 you would have your choice of DSX, PLIIz, or DTS Neo:X for generating height channels.

Is it OK to adjust the speaker distance after calibration if Audyssey measures one at a .5 or 1", I'm finding that when running calibrations there are small variations from a previous calibrations or is this a no no!

With the exception of the subwoofers, it is generally not recommended to adjust the speaker distances calculated by Audyssey. It is not uncommon to have slight variations in the distances because of slightly different microphone positions. I would trust what Audyssey calculates.

Thanks Batpig. I just figured some sports programming that may still be in 2.0 can possibly benefit from heights. In any case, it seems I'll be covered.

Yes, this is a fault in the skin designs offered by AVS. Done properly, the links would translate correctly to the offered skins. There is no way around it because if I change the colour of the links to suit the black skin, then they are bad for the regular skin.

It is not recommended to change the distances (delays in fact) set by Audyssey. Audyssey is very accurate in setting the distances (more accurate than the resolution most AVRs offer). The small variations are because the mic is not in the exact same place each time you measure (No 1 position).

 

e)2.   Is it OK to change the distance settings Audyssey sets?

I can't seem to figure out how you get the nested quotes in your replies?!

I use the Black skin and Firefox 17.0.2 (or 18 at home) on a PC running Windows 7. For me, the Quote button always nests all of the quotes that are in the post that I'm quoting. Like has happened here. I have to manually edit whatever is in the Content box to get anything else.

My understanding is that the MultQuote is for quoting multiple separate posts in a single reply Content box. I've only used it once, though.

I don't disagree with your description of what's generally, recommended, but I thought that the distances were all determined from the first microphone position, not from the later positions. So they should all be right (within measurement error) except for the added distance to the subwoofer measurement that results from bass management. Tell me if I'm wrong...

OK, to be precise, you can get slightly different distance (delay) settings if there is a slight variance in the placement of the microphone for the first measurement position of an Audyssey calibration.

 

Are we in agreement now?

Well done! There was an option to remove nested quotes on replies checked in my settings and that is what caused it. Thanks!

I don't understand what you mean by "variance." If there were two or more measurements, there would be a variance (as in the carpenter's dictum, "Measure twice and cut once."). But you're saying there is variance in one measurement??

No - you're at cross purposes. Jerry is saying the same as I said in my reply to the same question. The distance settings are set from the first mic position used (usually the MLP). If you make a million calibrations without ever moving that mic, you will get the exact same distance each time. If you pack it all away and then come back a week later to run a fresh calibration, it is almost impossible to put the mic in the exact same spot as it was before - this will give you a likely different distance setting. Audyssey measures the distance with exceptional accuracy, usually with much more resolution than AVRs have, which use either 6 inches or 2 inches AFAIK. Hence, move the mic a little and you are likely to get a different measurement. If the resolution of the AVR is 2 inches and the first cal was taken and gave a distance (delay) of say 10 feet 6 inches, it may have been right on the 10 feet 6 inch mark. Moving it a quarter of an inch for the next cal could tip it to the 10 feet 8 inches result - it looks like you have moved the mic 2 inches but in reality you didn't and don't need to in order to get that variation. IIRC, and ICBW on this, I remember reading on Ask Audyssey that Chris said the measurement was accurate to 0.2 of an inch. I have taken the liberty of editing Jerry's post for further clarity (edits in red above).

^ Keith, thanks for putting an end to what was becoming a peculiar discussion.
post #59397 of 70896
I've got a question regarding the use of RS SPL meter as a final check for trim level.

Here's a scenario:
Meter reads 75dB for L,C,R,SL,SR.
Meter reads 75dB for LFE.

Is the LFE level really about 75dB? The meter could be under-read in the low bass region. If we take the meter reading of 75dB, in reality, it could be 90dB or more?

I do know that there are many websites that post the correction table for different frequencies. How do we know which correction value to apply for when the AVR is playing its internal LFE test tone? Could the AVR be playing a broad range of bass pink noise?

It is best to stick to bold, italic and underlined text. CAPITALIZATION is also effective for making a point. Fancy colors are an affectation. smile.gif

There are correction tables for the RS meters in the stickies for the subs forum. None of the corrections is all that drastic. THere's no way, of course, to know how to correct when the test sound contains multiple frequencies.

Moreover, using the receiver's internal test tones is relatively certain to yield incorrect results, IMO. Those tones bypass the Audyssey corrections, so say a 8 dB peak may dominate the measurement you make, but simply not be present when Audyssey is implemented.

That wasn't the "problem." The OP inexplicably changed the background color (span style="background-color:rgb(241,241,241);line-height:1.231). (Link color changes are done locally in the browser.) I switched over to AVS Black and couldn't see it there either ....
