MiniDSP have already stated they have it working for their DDRC-24 and have indicated a release in Jan followed by support for other Dirac units.

Do we have any more color on whether the Lexicon units will be able to use un-used channels or at the very least the sub1/sub2 outs to get at the very minimum a 2 channel management system?

I'm hoping the new 16 channel monoprice unit will be integrating this.

So curious how this will work with the NAD 758v3 which only has 1 sub out. My guess is they'll have you turn off subs to measure one at a time to optimize the signal. Otherwise, perhaps they can re-purpose unused outputs (Ideally not the Atmos ones). Otherwise, perhaps another card...

This is exactly what I thought might be nice for the lexicam units as well...

Not terrible pricing when compared to dealing with going the miniDSP/MSO route especially if one has to go through the learning curve.

Edit: maybe I should walk that back a bit re: tier 2 $99 single sub. Dirac would have to show what is superior about Tier 2 vs. Tier 1 vs. what Dirac Live already does with the sub channel.

I don't see how that could work. Each sub must have a unique channel to apply EQ or you just end up with global EQ.

The NAD models are going to be out of luck. They all share a single channel even though there are two outputs. MiniDSP is going to be the only viable option. I hope by this time next year, Monoprice or Emotiva will be prime time.

June 2019 for the Monoprice, and considering the prepro is about as purpose built as they come for this new Dirac module - 5 assignable sub channels - I think it will be integrated on release.

This is a day 1 purchase for me, although I understand the risks of early adoption.

Wasn't the difference mentioned in the press blurb?
Dirac Live = equalization.
Tier 3 = above + bass management (crossovers).
Tier 2 = above + speaker/sub optimization (blending).
Tier 1 = above + multi-sub optimization.

I've got an Arcam AV860 which has dual Sub out's, however, i believe they are shared (internal splitter) but i had heard that all that would be required was spare pre outs which could be utilized?
Not seen anything official though, so it's a bit frustrating.

Thanks Andy. A bit weird that no news has come out of CES and Dirac was advertising a CES reveal on their website. A bit anticlimactic

It will be interesting to see what develops. Assuming it all works out, it's interesting to contemplate that it will have been Monoprice of all companies to bring a commercial hardware implementation of multiple subwoofer optimization (including integration of mains and subs) to a reasonable price point. Monoprice? Really? Harman has IMO dropped the ball by limiting such solutions to extremely costly hardware (and services).

Dirac has a history of celebrating obfuscation and avoiding transparency. For instance, from the Dirac "white paper":

Quote:

As already mentioned, the emphasis is on the logic of different approaches to equalization rather than experiments. Logic can be checked by the reader, whereas experiments carried out by others always leave room for doubt concerning experiment conditions. Furthermore, as probability theory teaches us, one lucky experiment shows nothing about the underlying rationale, but the underlying rationale will be much more indicative of future experimental outcomes.
The equations are what provide transparency into the techniques being used. This is a kind of high-octane propaganda which attempts to vilify those actors who actually explain their actions, in favor of an "ignorance is strength" argument.

Any more news on this? I'm using an Arcam AVR390 with six passive subs that I run in mono. Interested if anything new will pop up for the Arcam that could be of use to me with my setup.

Promising. Too bad I can't get in on that... Just hope the beta period goes smoothly so us AVP owners will get an update within the year.

From Dirac Live Bass Management Makes Residential AV Market Debut at CEDIA 2019
Quote:
Arcam, JBL Synthesis, NAD Electronics and StormAudio become the first manufacturers to feature Dirac Live Bass Management in their AV products.
Quote:
Dirac Live Bass Management aggregates measurement and location data from each subwoofer to determine how a system’s bass is distributed throughout the room. It then identifies gaps in the sound waves and distributes bass evenly across the room. Furthermore, the solution corrects the low-frequency sound waves produced by the speaker pair, so the bass produced by each speaker is in sync with the system. All of this processing enables the subwoofers to be positioned anywhere in the room – wherever most aesthetically pleasing – without sacrificing performance for design, or vice versa.
I am looking forward to their CEDIA Master Class session to get some clarity on this claim. Is this somehow related to Dirac Unison or just loose marketing?

Thanks for the link, Marc.

> All of this processing enables the subwoofers to be positioned anywhere in the room – wherever most aesthetically pleasing – without sacrificing performance for design, or vice versa.

That claim sounds a bit overwrought, but we'll see how far off it is.

> Dirac Live Bass Management, the first in a series of modular add-ons for Dirac Live, is available in two versions: Single-Sub, for single subwoofer home theater systems, is priced at $249, while Multi-Sub, for systems with more than one sub, is priced at $399.

I wonder if there's a limit to the number of subs, as the more there are, the more complex the optimum solution for the subs' levels and phase.

I agree. The laws of physics can be bent but not broken. I wouldn't be surprised if that sentence was modified moving forward.

I know that up to four will be supported. I'm not sure if more can/will be. Four is the threshold of diminishing returns IMO. Of course it will depend on the processor's capabilities (1, 2 or 4).

I'd like to know if a miniDSP DDRC (which is a 2x4 HD w/Dirac license) could potentially utilize the new DL Multi-sub Bass Management, integrate with a Dirac Live enabled SSP. @flax , can you comment on the possibilities for utilizing Multi-sub with external hardware?
