Great news!
This will build some real anticipation I hope, as well as some Emotiva faith.
I linked to this post in the other threads...

First off is this! The current version offers two independent Speaker Presets, each of which can store up to three Dirac Live room correction profiles, along with one manual EQ profile. Various menu options allow you to choose a default profile, associate particular profiles with specific inputs, or manually switch between profiles on the flY. way too go! A lot of people asked for this on the XMC-1 so it is great that we have up to six Dirac profiles across the two speaker profiles on the XMC-2/RMC I am thinking one Speaker Profile as “all Small” for movies and one Speaker Profile as “All Large” for my music (stereo and multichannel) Previously I on the XMC-1 I had to leave the All Large setting without Dirac as it always sounded better than mains/sub through a crossover hmm. Even with my "All Small" profile there is room for one Dirac profile to be optimised for the single person at the sweet spot, and one with whole sofa measurements. One more profile for?  ? |

I have read the manual from other product sites and it basically seems to work very much like 1.0 except for allowing different numbers of measurements. I'll read this new Dirac 2.0 manual in detail to see if anything looks different.
Over the past couple years I did many dozens of Dirac 1.0 calibrations and REW measurements with the XMC-1. I experimented with different speaker positions and configurations as well as different Dirac measurement patterns and target curves. One issue that existed with Dirac 1.0 was that it did not look at bass management at all. It measured the sub channel(s) and all the other channels separately. It created filters for each channel separately including separate filters for multiple subs. When you played it all together with bass management, the ACTUAL response with Dirac correction (which Dirac never actually measures) could have some issues at the crossover points. For example: I have a big peak room resonance at 40Hz but I want to cross my Magnepan 3.7 L/R speakers at 40Hz. Dirac corrects the sub at 40Hz AND corrects the L/R speakers at 40Hz. I end up with uneven response in the crossover region, play with the Dirac target curve to compensate, etc. I expect to find the same behavior in 2.0.

Dirac Bass Control is what will achieve (attempt to) what you are talking about. |

So this might be posted elsewhere, but do we have to do anything in particular to acquire the "LBB" or will it just be sent out automatically in the mail to anyone who has ordered a processor?

I'm sure they'll have a process to confirm current shipping addresses. Remember, many purchased their RMC-1's a year and a half ago. It's reasonable to assume some have moved in that time frame. |

Sill wonder how Dirac's Live 2 extra cost multiple subwoofer feature can measure how multiple subs interact and therefore correct said interactions in a given room using only the same dedicated sub signal to all subs. Or is that only a function of Dirac Unison? I guess I had assumed that the RMC-1's future expansion module(s) would be necessary and presumably able to send an individually corrected mono signal to each sub, with the correction computed upstream in the processor.

The RMC already has 3 dedicated sub channels. Your question is a bit confusing. |

Yes,the RMC-1 currently has three 'dedicated' sub outs, but with each out sending the same mono signal. In this configuration, I don't see how Dirac can differentiate multiple subs receiving the same signal. Besides, I have four subs (currently all y-connected to the ULF mono signal). I want to upgrade this arrangement to permit the room interaction of these subs to be optimized.

I want to upgrade this arrangement to permit the room interaction of these subs to be optimized. What are you watching or listening to that has 4 separate lfe tracks? They are all derived from a mono sub signal. It's the "post processing" ability that allows one to manipulate time, phase, crossover, and eq for 1 or many subwoofer outputs from the same mono signal. What am I missing? |

I realize that all multichannel music and movie sound tracks have only a single LFE signal. It's the potential room interaction(s) of multiple subs' low frequencies that I want to improve, i.e. the positive and negative summations of low frequencies that subs produce throughout the room. It would seem that this is only possible by individually adjusting EACH subs' signal WHILE THEY ARE PLAYING AT THE SAME TIME in the given room's acoustics
Sorry if I can't explain it better.
Also, from page 71 of the RMC-1 manual:
"The RMC-1 supports up to three subwoofer; each of which receives the same monaural LFE and low frequency content. The left, right, and center designations are provided strictly to aid in identifying each subwoofer by connection and room location."

Here is our User Manual for Dirac 2. Proofreading: Page 10 should say macOS, not iOS. Page 11 should say Dirac, not DIiac |

So am I understanding this correctly:
Dirac for the Emotiva will not set Distance, Level, or Size?
It will only generate a EQ filter set?

I've been reviewing other implementations of Dirac 2.0 and DBC, it looks like those implementations allow for both, but most of zeroing out the items outside of the Dirac section. |

Bass management is outside Dirac Live and most every other room correction system. But, starting from whatever the AVR/VP feeds it, Dirac Live will adjust level and phase ("distance") at each frequency it corrects. This is similar to "all" room correction programs. |
