Dirac in the 2021 Onkyo AVRs

[kovacsgergely83]

Nice to bump into familiar "faces" here as well from the "big" AVS Forum topic. Any owners interested in sending his RZ50 to Amir for a thorough measurement...? Cheers.

From best to good:
- DLBC with multiple subwoofers on individually addressable subwoofer outputs
- DLBC with single sub or subwoofer cluster on a single subwoofer output
- "Regular" DL with single sub or subwoofer cluster on a single subwoofer output

Avoid at all costs:
- "Regular" DL with multiple subwoofers on individually addressable subwoofer outputs

Much appreciated. Is all this with (i) "small" mains and all bass sent to the subs or (ii) "large mains" and subs? (I'm running a stereo set-up with mains running full range as per Geddes but thinking of moving to an AVR or Pre-Pro for 2.3 or 2.4 and wondering if I'm a dinosaur with the Geddes model.)

我想在先锋也是如此。

看起来不错

Flavio from Dirac has clarified that the Onkyo/Integra/Pioneer implementation is limited to 48K sampling rate, as opposed to the PC/Mac implementation which can go as high as 192K, possibly more.

He also pointed me to this video:

Same as for Audyssey MultEQ XT32

And your ears.

...but only if the up- or down-sampling of the input signal is done well.

You ALWAYS want your speakers set to "small" regardless of their low frequency capabilities. A wide overlapping crossover region optimization assumes all low frequency content would be monophonic. In reality it is not. A more detailed discussion can be found at https://mehlau.net/audio/bass-management/

Much appeciated - the article has a great no. of insights. Is there a need, or change in the conclusions, if the sub-woofers aren't identical?

Onkyo and Pioneer AV Receivers Get Dirac Live

Dirac Live, the sophisticated speaker setup/room correction system developed by Swedish technology company Dirac, is for the first time making its way into the mainstream AV receiver (AVR) brands Onkyo, Integra, and Pioneer Elite. The processing technology, which has been largely confined to...

Is there something new here, other than new models? If not, I'm not sure why this article was posted today.

I've read, and re-read, the blog several times, and have a specific question. Is the conclusion to not run the mains full-range the right answer for stereo (2-channel) sources? Or is, in this case, there benefit in running the mains full-range? Thanks in advance

It depends, but I would think that in most cases it is better to not run the "mains" full range. So when you said "..in this case...", what would be the case? Would it be that your speakers are more bass capable than your subwoofer, can take a lot of juice and play loud, you can place them in your sweet spot and they produce very smooth bass response, and/or you use Dirac Live?

... "the case" to which I was referring was Stereo rather than Multi-Channel (as the article speaks to the complexities of the latter and, potentially, most stereo is mixed with mono bass). My actual situation is capable mains (in-built active bass) that run full range along with capable subs that located around the room as per Geddes. The article gave me an appreciation for the theory behind mono-bass that make me question whether a better response might be possible via high-passing the mains.

With capable build in subs and followed Geddes guidelines, you may just compare the bass response between your build in subs and your independent subs and then decide. If both are more or less equal then I guess you can just go by ears, or take some measurements (I would) with REW and go from there.

 

[Flak]

Sorry, no measurements in this user's review

 

[dlaloum]

Question - for those who already have one of these.... can Dirac be applied to Zone2 or Zone3? (I think the answer may be no....)

I'd be really surprised if it could handle more than one zone/setup.

ps Altho I think this could be a great feature in multi zone avrs, to have such for each zone.....

ps but the distances involved in placing appropriate measurement mics....meh

 

[Rottmannash]

Does anyone know if these are available anywhere for sale yet?

I was thinking about using in ear mic's to do a Dirac setup for headphones, and connect a HP-amp to a Zone... but that is only viable if Dirac works on the Zones. (which is probably unlikely)

I'd doubt it would work with the headphone output in any case, even in the main zone.
