1) As you now realize I don't have the 3700, my potential candidates for doing what I want in one of my 2 ch system are:
a) X3600H, X3700H, even X3500H, but I don't thing I can find one new, and am always skeptical of used ones that are out of warranty.
b) MOTU M4, but I am not sure if I spent $400 on the M4, how would I do volume control, to pair it with a 4 channel preamp or 2X2ch preamp is not going to be tricky.
c) Give up on using 2 subs with my BMRs, but just 1, in that case DLBC would seem under utilized, though with the discounts I wouldn't complaining much about it.

Ideally, I would like to use a real 2.2 receiver or integrated amp but there is no such animal that I am aware of. If Dirac has a smart and more risk taking marketing team, they would work with the likes of D+M, NAD, Arcam etc., to market a real 2.2 device instead of settling on the silly subwoofer outputs that are simply connected to the left/right channels no different than using Y-connectors externally.

To be clear, there are no 2.2 or even 2.1 contents for HT, but in my opinion, manufacturers should take a risk and do try marketing such a product if they would bet on room correction such as DL will soon gain popularity.

May be they are smart enough to know that 2 channel audiophiles are too ignorant to know that they could have much better perceptible sound quality by using a mid range gear such as DRA-9000H, NR1200 if such unit can take advantage of DLBC, or the likes of MSO that can integrate the bass of capable tower speakers and multiple subwoofers. It is probably a fact that the 2 channel crowds typically get fixated on the so called sound signature myth, such that they believe for example, there are night and day improvements simply by "upgrading" from their NR1200 to an Anthem STR integrated amp, yet in a DBT they would not be able to perceive much difference if at all, whereas the difference between with and without the use of RC such as DLBC would be much more obvious. In other words, it is likely true that people don't know what they miss, and keep chasing the wrong thing that only work because of their tendency to get easily influenced by marketing information and the price points of the so called high end gear.
+1..

Now something on interest to me, perhaps a bit off-topics.
I may have to change my X-3400 because it is old. It functions well and Denon still send updated firmware (the latest one on the second week of December 2023).
I may swing toward the 4800 because of the performance, or the 3800 because performance is good enough for me.
Not because of Dirac. I am not yet convinced by the numerous threads and mentions. No one has come out and say it is better than Audyssey. I am however convinced by Audyssey MultEQ-X. It is a very good software , which add a great control to the capabilities of Audyssey. I find the value proposition better than anything DIRAC presently offers... I haven't tried DIRAC in my system , just read about t.

Happy holidays!

Peace.
 
Amir's review suggests it no?
Itwouldnt make any audible difference though.
In that case, no, Amir did not have Audyssey on in his measurements. As far as I know, if you use Audyssey, it will down sample to 48 kHz regardless of the source media contents you play. I would agree that it wouldn't make any audible difference, but as usual, there are people who will say yes it will make audible difference and you most likely can't change their mind.
 
Are you using Audyssey (with the $200 or $20 app) or Dirac?
Just Audyssey that came with. I also used the Martin Logan Base correction through the iPhone app. Again just free versions. I did not notice any real difference after using ARC. I had already run Audyssey. Did not seem like the extra correction did anything.

It is a great receiver. I love mine, sounds fantastic. A mate bought the 3800h and had a big grin after I set it up for him. He came from a Pio LX85. The app is a worthwhile purchase.
 
Audessey (non MEQX) has a 30hz high pass filter that requires wither MEQX or post amp EQ to defeat.

Can anyone confirm if DIRAC has a undefeatable high pass filter?

I do not know if that is true about Audyssey.

Dirac definitely does not have such a filter. You can actually increase bass extension if you do not need to worry about distortion.
 
If I remember right, D+M had a 20 Hz filter for a brief period in the early dates of the MultEQ Editor app. That would be in effect if the app is used to run calibration, not sure about if running it on the unit itself. Probably because people complained about the drop off shown on the predicted curves, D+M removed that in a hurry. If MultEQ X had such a thing, I doubt it would last long either, even if it can be disabled.
 
Hi. Does anyone know what frequency range is the signal (75dB) that Audyssey sends to the subwoofer during setup?

Based on the Audioholics.com's interview with Chris, probably all the way down to 10 Hz. The interview was down in Aug 2014 so things could have changed since.


Audioholics: What is the default frequency range corrections are applied to? In other words, is there a frequency ceiling or floor above/below which correction isn't applied? If correction isn't applied full band, please explain.

Chris Kyriakakis
: MultEQ is capable of applying correction from 10 Hz to 24 kHz. However, during the measurement process it first determines the roll off points of each speaker and subwoofer, and limits the correction below that point.

Audioholics: The top frequency for correction is 24kHz, implying that Audyssey is functioning at a 48kHz sample rate. Does this mean that high resolution content (for example 192kHz or 96kHz sample rate PCM) will be downmixed?

MultEQ is capable of applying correction from 10 Hz to 24 kHz.
Chris Kyriakakis: There are two parts to this answer. A loudspeaker does not reproduce acoustic energy above about 24-30 kHz even if it was in the content (with the exception of super-super tweeters), and a microphone cannot capture acoustic energy above that range. So if there is no information captured then, there is nothing for the filter to do up there.

Thank you. That explains a bit how the Audyssey works.
 
Thank you. That explains a bit how the Audyssey works.
The Audyssey test signal is a logarithmic swept sine (log chirp) covering from approximately 2.93Hz to 23,997.07Hz over 341.33ms at 48kHz sampling rate. It repeats 10 times, repetitions are used to "denoise" the signal. This signal resolution is 2.9Hz, provides a fairly low crest factor and is a continuous waveform that is easy on equipment and speakers.

A logarithmically swept sine has a "pink" spectrum, but is not pink noise. There is also a brief period of "silence" (background noise) measured before the chirps start to evaluate background noise and compute an SNR.

Hello everyone.
Today I received an email from Dirac that the promotion for Dirac Live Bass Control ends on January 15. Last year I bought a Room Correction Full Bandwidth license. I heard the difference after configuration :-). Do you think it's worth buying BassControl? My front speakers are Definitive Technology BP9080. Surround BP9060. You could say that there are 4 subwoofers to tame. In my opinion, these licenses are quite expensive. Thank you in advance for your response.

I just got the email a few minutes before your post. I will not be buying DLBC since I only have one sub, yet my main speakers can product more bass than the sub, and I heard that DBLC will cut off the bass from the mains.

I would suggest you don't go by what you heard, unless you heard it from someone who really knows what he/she is talking about, sort of the authority...

Similar, I would ask the question of how DLBC work with genuine full range speakers as those DT's have inbuilt 12" and 10" subs. I don't see why it wouldn't work. One for @Flak to comment on. Probably expedited as you are on a hard deadline as to the 30% discount :)

Absolutely, someone like him would be worth listening to, though keep in mind he is naturally biased. My point is that lots of forum posts seem to indicate may hobbyists might be taking forum talks, including from reviewers, users who might be brand fans/loyalists too seriously. Obviously you are among the exceptions who at least know about @Flak , who is knowledgeable in DLBC for sure. One question I would like to ask Flak, is to confirm what Phil Jones alluded to in the recent D+M update YT video, that D+M/Masimo will get DL (that is without BC) to do some bass management too such as crossover. If that is true, I would think that your "genuine" full range speakers may not need DLBC, but I am not the authority so let's hear from flak, or you can open a ticket with Dirac's help line and hopefully get a response quick enough.

I did get the discount for my DLBC license (PC standalone only) and I tried it with one sub, quite happy with the results, I posted the FR graph not long too.

Edit: Found my graphs, linked in case you are interested to seeing:

I added DLBC to my full spectrum license using that discount. My results are here:


And here is a decent roundup of the available DRC options in an X series Denon receiver:


Take my opinion with a grain of salt, but I cannot hear much if any difference in my setup in my room. But I am in dedicated room with symmetrical placement of speakers and subs. Perhaps someone with a more complicated environment would benefit more.

Quite honestly, I think my Audyssey results, although a bit different, are just as good as my Dirac results and I could have skipped both licenses, but curiosity killed my wallet. :)

This is what I'm most afraid of and why I'm skipping DLBC. Although my room is not as ideal as yours, the only benefit from full-range DL for me over prior RC has been the much clearer dialogue and some improvement to music content.
