I’ve been holding off on starting this thread until we had some positive word on the Dirac release, with Lonnie’s announcement on beta, I think this is the right time. Edit: Dirac has now been released for the G3P, this thread is Official!The current Dirac discussion, in both the ‘Success at Last’ and the RMC/XMC Owners thread, is getting pretty interesting and more details are coming to light. I think this important and specialized topic needs its own thread, and we need a dedicated place to continue the conversation, and especially to share our experiences once Dirac Live is released for the RMC-1, RMC-1L, and XMC-2. This thread will complement the ‘Owners Thread’ where general topics are discussed, we won’t bog that thread down with lengthy technical discussion, and allow it to help users with more typical use questions, I’ll put references there directing Dirac discussion here. We can use this thread for learning, sharing, and discussing our research and experiences with Dirac Live including Dirac Bass Control. We can then leave Hair Nick 's ‘Success at Last’ thread for the “when will it ship?”, “will it come automatically?”, “I didn’t get mine, what should I do?” questions. Hopefully this thread can stay mostly technical; how to, results, theory, new information.I’m not claiming any Dirac high ground, but will do my best to keep the second post up to date with relevant resources, information and links — I’m sure LCSeminole will also help out, and you're welcome to make suggestions, or post links too. The third post of this thread contains useful acronyms and a FAQ, I’ll try to keep that current as well. It might even be useful to copy some of the posts from the other threads, but I’ll leave that to those who wrote them, if you have some good information and want to carry it on here please feel free to copy and continue. I hope to learn along with the rest of you how we can make best use of Dirac with our systems. —Bruce —> 2nd Post with Resources and Links—> 3rd Post with Acronyms and FAQ |

Acronyms (to lessen the typing load)DL : Dirac Live (assume current version unless otherwise stated)DLBC : Dirac Live Bass Control DLBCSS : DLBC for a Single Subwoofer DLBCMS : DLBC for Multiple Subwoofers DRC : Digital Room CorrectionEDNIB : Emotiva Dirac Network Interface Box (aka LBB) FAQ : Frequently Asked Question G3P : Any of the latest Generation 3 Emotiva Processors: RMC-1, RMC-1L, XMC-2 MSO : Multi Sub OptimizerTLA : Three Letter Acronym FAQ (the answers may change as more information is revealed)
Q : What is Dirac?A : Dirac Live® is an advanced digital room correction technology that utilizes sophisticated analysis of the speakers and the room to correct these colorations.Q: What do I need to use Dirac on my G3P? A : The following are the requirements which will allow you to run the Dirac software, take measurements, and upload filters.
- You’ll need the Dirac Live software which runs on a Windows or macOS computer or laptop. The supported platforms are: Windows 10, macOS Mojave (10.14.x), and macOS Catalina (10.15.x). This software is only used while you are taking measurements, creating filters, and uploading the filters to your G3P. After that the computer is not needed, unless you make changes or take additional measurements.
- You will also need the EDNIB package delivered by Emotiva, they began to ship on 7/20/2020 in order of purchase, it may eventually be included with the processor.
- You should always use the latest recommended or required Firmware for your G3P, for Dirac to operate you must have at least version 2.0 — you can now download it at the link above.
- While you’re actually running the Dirac Live software, the computer, the G3P, and the EDNIB, must all be on the same logical network — with access to the Internet. The EDNIB package will include a small network switch to facilitate this if needed.
- To hook up the Emotiva measurement microphone included with your G3P, the computer needs a USB-A port. Other compatible microphones may have different requirements (the UMIK-1 can use USB-A or C).
- To get the most accurate measurements you should download the calibration file for the microphone you use (Emotiva and UMIK links above).
- A mic stand with boom will help make your measurements more accurate and repeatable
- More details are available in the Emotiva Dirac Owners Manual linked above
Q: Are there any known issues with the current Firmware and Dirac? A : The following notes are highlighted in the FW2.0 release document.
- Special Update Note, only for XMC-2 owners
- Due to the way this update interacts with the hardware on the XMC-2 there is a special note for running Dirac Live.
- When you enable the connection to Dirac Live in the Speaker Preset, your amplifiers will be triggered off.
- Therefor - before running Dirac Live on an XMC-2 with this Firmware release installed ...temporarily disconnect the trigger connections on your amplifiers and turn your amplifiers on manually.
- (This is only necessary while the connection between your XMC-2, the Dirac Live Network Interface box, and your computer, is enabled.)
- Alternately, with Emotiva and some other amplifiers, you can turn the amp on manually after they trigger off.
Q : Where do I get the Dirac Live software and what version do I use?A : You will download it from Dirac via the link above, you will always use the ‘latest’ version, which at this time is 3.xQ : How much does Dirac cost?A: The base DL Software license is included in the cost of your G3P, so it’s free to you. The DLBCSS add-on is $349, the DLBCMS is $499.Q : When will Dirac be available for my G3P?A: In mid June 2020 the EDNIB and Dirac compatible firmware was shipped to Beta testers, they began to ship on 7/20/2020 in order of purchase,Q : Will the G3Ps support DLBC?A: It is not expected that DLBC will work with DL ‘out of the box’, but Emotiva has stated that they plan to support DLBC (here).Q : What are Dirac Filters?A: Filters are the results of the measurement, analysis, and correction process, they are uploaded to your G3P to apply the individualized DRC to your system.Q : How many Dirac filters can my G3P store?A: The G3Ps have two speaker presets, each preset has four ‘slots’, three of these slots can hold Dirac filters, the fourth can hold a user setting. So the G3Ps can hold a total of six Dirac filters.Q : Why would I want more than one Dirac filter?A: Some might want one filter for a home theatre configuration using surround and possibly immersive speakers, and another filter for a two channel setup for music. It may also be desirable to have separate filters for Dolby Atmos and DTS:X. Some might even want different filters for various seating locations. Q : If I backup my settings with the Menu > Setup > Advanced > Backup option, are my Dirac filters saved?A: All of your Dirac filters are saved when you do a backup, they are deleted when you do a factory reset, and put back when you do a restore.

Here's to a successful and short lived beta program so that we may soon be enjoying the fruits of what is arguably the best room correction system available.  |

Aren’t we all beta testers for these processors anyway?
Sounds better than being gamma testers, in any case.

Excellent! I'm ready, willing, AND RETIRED! So I will be doing a very comprehensive test of Dirac 2+ or 3+ when we get it. Having a good year and a half of dozens of calibrations with Dirac 1.0, and having read the Manual (twice) I will leave no mode unturned :-)

I'm just wondering how much is really needed to beta test. Isn't the actual software from Dirac used by all manufacturers employing this room correction software in their processors? If so, then NAD, Storm Audio, Trinnov, Monoprice, Arcam, JBL, Audio Control, Lexicon, etc., etc., processor owners should have already paved the way in cleaning up bugs in the Dirac Live software.
I'm guessing the beta testers in the field will be verifying that the "network interface" box is correctly communicating between the Emotiva processors and the latest Dirac Software that's running on your computer, while taking room measurements with your choice of mic with calibration file.

Emotiva’s implementations of Dirac allow upgrade to 3.0? Hmm It is to be whichever version is the currently available one. So, V3.x. Seems like the best way to get a straight answer on a simple question is to take a bunch of guesses until someone decides we've drifted so far off the mark that an answer is warranted. So here's my guess: 1 - I shouldn't have said "2+" in my previous post ... from now on it's 3+ for everyone. From everything Emotiva and Dirac have said for this "post 1.0 era", there is only ever one production version of the Dirac code that runs in the PC. So if Dirac is shipping 3.0, we all get 3.0. When they ship 3.1, we get 3.1. It runs in the PC, and everybody gets the same version. 2 - The version of Dirac has nothing to do with Dirac Bass Control from here on. The current and future versions of base Dirac support DBC, but support for DBC in your processor depends on the product manufacturer. 3 - Given that we need the Emotiva interface box to enable communication between Dirac running in the PC and the RMC/XMC, then there is a CHANCE that a future version of base Dirac might require a code update to the interface box and/or the RMC/XMC firmware. The latter might be Dirac code, Emotiva code, or both. 4 - The beta testing now going on has to do with the following (my wild-ass guess): Activation/license verification process; Implementation of the interface box hardware/software for stable control of the measurement process and transfer of Dirac configurations from PC to RMC/XMC; Implementation of menu items in the RMC/XMC (Preset menus and functions as previously described). We can assume the actual running of Dirac filters in the RMC/XMC has already been verified and is not part of beta test. Anything else we need to be clarified? Hopefully Keith or Lonnie can just give this description a thumbs up. |

Is this field beta public enabling those who receive the LBB etc to share their experiences on this forum?
If so , great , this thread makes sense. If not then I think this thread is created prematurely and will just turn into a rant thread.

You are on the right track. The software will be the same as what everyone has. The big difference is how it communicates to our system. The DSP work is done (which was a nightmare) so now it just comes down to field testing the coms package. Lonnie |

If not then I think this thread is created prematurely and will just turn into a rant thread. I can’t answer the first question, I’d imagine results will be reported confidentiality, at least at first, but we’ll see. As for being premature, I did struggle with timing, but a good amount of useful discussion kept popping up and I felt it was time to capture that in one place where it could then continue uninterrupted by other topics. As for rants, there have been several in the other threads, I’ve asked for this thread to be technical and informational, if too many non-productive posts appear I’ll ask the mods to clean it up, but I hope it will be a good discussion, reference, and reporting resource. |

Emotiva should consider the private beta, followed by a public beta.
This is the methodology employed by Oppo before general release.
It is a bit harder when additional hardware is required.

Emotiva’s implementations of Dirac allow upgrade to 3.0? Hmm It is to be whichever version is the currently available one. So, V3.x. But, we need to differentiate. Dirac Live (V1, V2, and the newest V3.0.0) is the software that takes measured room response and generates room correction filters. Most users will probably generate the same kind of filters that Dirac Live (Full Range rather than Lite) on the XMC-1 generated. V3.0.0 introduced Dirac Bass Control filter generation capability which everyone should use on Dirac Surround Sound Processors but which some users can select as an enhanced alternative to standard Dirac Live filters, . Using Dirac Live 3.0.x does not automatically mean we get access to the Bass Control aspect. Dirac Live 3.0.0 has a better looking interface than 2.x AND will allow access to the optional Bass Control filter generation for people who: Have a Surround Sound Processor that supports Dirac Bass Control (Highly unlikely to be the XMC-2/RMC when we first get Dirac but Keith states it is their intention to add support later) AND either: a) have a Dirac Bass Control license included in the cost of their processor (This won't include Emotiva processors) OR: b) Purchase a license from Dirac at $350 for single sub / $500 for multi sub For those users, V3.0.x and beyond allows them to generate both standard Dirac Live and Dirac Live Bass Control filters to use as a filter set. For the rest of us, 3.0.x will only allow standard filters |

I am not too impressed with the upcoming Dirac filter configurations for the XMC-2/RMC models. I know it is not here yet, but I can already see some optimisations that would suit more users better if they were possible.
I know I should not grumble, we were all wanting more filter sets than the single one offered on the XMC-1, but the upcoming XMC-2/RMC Dirac will, in practice, only give two configurations (with the other four having to be manually selected)
Incoming Dirac/Speakers config - Two speaker presets with fixed number/size/position configurations, each with a choice of four equalisation setups: 3 Dirac Live filter sets and one manual setup for PEQ
The problem with this choice is you only have two setups in reality, as the Dirac filter set defaults to the last one used in that preset. You have to manually change the Dirac filter within the config.
If possible I think it would be better to have 6 (or more) completely different speaker configurations each with one choice from two equalisations (Dirac/PEQ/(or None)) rather than two speaker presets with four equalisations each (giving 8 configurations in theory but only two are easily selectable)
In my idea, a user sets a speaker config and can then set one equalisation to be used for that preset (from Dirac / Flat / Manual(Peq) ), and then measures and generates a single Dirac filter-set within that config to use as required
There would still give six stored Dirac filter sets, but in six configuration presets, rather than two.
e.g.
Config 1: User set as default on Input 1 for music listening: 2.0 All Speakers Large, Flat(No Dirac or Eq)
Config 2: User set as default on Input 2 for Blu-ray disc player/HTPC: 7.2.4 All speakers Small, Dirac (Filters measured with living room doors open to hallway as per normal setup)
Config 3: User set as default on Input 5 for PS4: 7.2 speakers (tops not included), all small, (but differently calculated Dirac filters measured with the microphone at the main listening position on beanbag recliners in the middle of the room rather than sat on the sofa)
Config 4: 7.2.4 All speakers Small, Dirac (but differently calculated Dirac filters measured with the living room doors closed rather than open)
Config 5: 7.2.4 All speakers Small, Dirac (but differently calculated Dirac filters measured with the microphone at a narrow listening point on the sofa / front row of seating for one person/selfish listening)
Config 6: 7.2.4 All speakers Small, Dirac (but differently calculated Dirac filters optimised for multi-row seating with the microphone measuring over a wider listening position and covering all rows of cinema style seating)
etc etc.
I think it is more likely that the listening environment will change (Doors open vs closed, front row vs multi row, Single user vs multiple listeners) rather than the number of speakers in the room.
For me, with the upcoming speaker presets, I am likely to have speakers presets 1 & 2 both set up as 7.2, and measure different Dirac filers for different listening patterns as I can see four or five that I might quite like. I won't also be able to have just one 2.0 stereo non Bass Control speaker config.
My setup idea still has six sets of differently measured Dirac filters, Like the upcoming Emotiva model, but any of them can be set as default for that input, or flipped to manually
