After Filter design but before proceeding to Filter Export, save the project with a meaningful name. Then close Dirac, reopen it, connect to the XMC-2, load the project, and proceed to Filter Export. It was more stable for me doing that. |

Yes it probably did. BTW just for everyone's general info ..... when I do a calibration I save two or three times: - First save is after Measurements and before proceeding to Filter Design. I call the project by the date and "Measurements". It's important to do it before going to Filter Design because that step does preprocessing that can't be undone. With Measurements saved, if Dirac crashes you can get back to that point without redoing the measurements. It also allows you to re-take measurements, eliminate some, etc at a later date. - Second save is after completing Filter Design and before proceeding to Filter Export. This save includes the preprocessing, speaker groups, target curves and curtain positions along with the corrected frequency and impulse response filters. Again, it's good to have it saved in case Dirac crashes during export. Name it with the date and something that will be meaningful to the slot where it will be downloaded. - Third save is just for insurance and because Dirac seems to complain if you don't. This one is after Filter Export completes successfully. For some reason Dirac says it saved the project but if I don't explicitly do a save it asks if I want to save or discard changes. So if Dirac doesn't crash after the export, I save. |

Just a few observations and questions from my recent Dirac run. Just got my RMC-1L back from Emo repair for a 'dead' network plug connection.
Hooked up the switch/LBB without problem and opened Dirac- Dirac found my unit w/o problem. I was offered the opportunity to upgrade Dirac to latest version -3.0.13 - and did. But I really wanted to go to 3.0.11. Question #1- Where do I find the different Dirac versions ??
Ran for speaker preset #2 - 7.1 speakers first- The mic gain and master volume setup was fine, but when I got to the individual speaker levels the subwoofer level was way high. I needed to lower sub about 7dB to get it in the blue. When I originally got my RMC-1 (before Dirac) I set the speaker distances, sizes, x-overs and levels. Matched the levels using SPL meter (C-slow) in the RMC-1 for all speakers except for the sub, which I used the subs own volume setting. Sub level set to 0 in Emo, adjusted in the SVS volume setup, so it theoretically should have been within a dB or so. Lowering by 7dB seemed extreme- wonder if this is a Dirac problem with 3.0.13. Also wonder if this might be why some are having increased sub output after running Dirac 3.0.13. FWIW, when I checked speaker levels after Dirac (set all levels to 0 after Dirac- will try to remember to do it before next time) and all levels were within 1 dB and sounded great.
I use the 'tightly focused' seating and found out something interesting to share. Dirac highlights the next speaker after each position is done, but you don't need to do that position. I could click on the position I wanted to run if I preferred. I found it easier to run all the 'upper' mic positions, the all the 'lower' mic positions together so that I could keep the mic hieght the same for all measurements.
After measurements I went to Filter design. I'm used to adding extra adjustment dots by double clicking, but was unable to add extra adjustment points. Question #2- How do you add extra adjustment points ?? I was able to slide the available 'dots' to where I needed for what I wanted to do, but is there a secret to adding more 'dots'? Didn't see how in the manual. BTW, Thanks to marcl I saved both the 'base' Dirac correction and my adjusted correction with different names.
Loading and export went fine except for the fact that Dirac auto shut down after export. But the program showed export complete before the shut down.And showed up in correct slot in the RMC-1 menu.
When I went do the run for Dirac for preset #1 (2.1) I needed to do a hard reset of processor and LBB (forgot to turn off in setup before backing out). Wondering if Emo could combine the 'disable Dirac' and 'turn off box' commands together so that disabling Dirac in the menu automatically shuts off LBB ??
Bottom line is that running Dirac is a little glitchy, but the results in my case are outstanding. Well worth the effort.
Thanks for all the help here guys.
Edit- Running v2.2
All speakers set to small and one sub (center) not set to LFE only.

Edit- Running v2.2 All speakers set to small and one sub (center) not set to LFE only. Add or delete extra control points to the target curve by right-clicking the curve. Yes you can do the measurements in any order, and if you pick focused but just want to do 11 instead of 13 you can do that too ... or space them in a way that makes sense for your listening position. I have had similar problems with 3.0.13 crashing and sometimes it leaves my XMC-2 in a bad state and I have to do a cold reboot. That's why I save so often. I have found that if I save the project before filter export, shut Dirac and reopen it and connect to the XMC-2, load the project again and proceed to filter export ... it goes a little better. A note on setting Volume in Dirac as it relates to subwoofer levels and maybe levels in general. The sub volume setting needs to be set so the sub and the other speakers measure at the same level. After one measurement, look at the graphical display on the right and be sure the sub measures the same as the fronts at least. For me that means setting the Volume for the sub in Dirac about 7db higher than the other speakers. But it will vary depending on speakers, amps, etc. As Dirac recommends, I leave the Volume for the sub all the way up and adjust it at the subwoofer if necessary. |

For those who use Mac, to be able to Right Click on a Trackpad, this can be setup in System Preferences. Go to Trackpad and find the Secondary click selection, just select "Click in bottom right corner". Then, to Right Click all you need to do is click the lower right corner! I couldn't find any other solution without using a mouse.  Also, Dirac still has the wrong file associated with the 3.0.11 download link for Mac OS. If selected it will download 3.0.9 instead. |

Hey All, Not sure if this is the right thread but I’m having calibration issues with my RMC-1L and was hoping I could get some user support. After running Dirac I’m getting strange results for my subs. I have two REL Predators (1508s) in my 25’x13’ basement theater and Dirac is measuring significant roll off after 50hz. I’m posting using my phone and don’t see a way to paste an image but what it shows is -15db at 50hz and -25db at 40hz before dropping off completely. The speaker measurements appear fine out to 10khz by the way. I’ve attempted to independently measure my subs using REW and got similar results so I don’t think it’s Dirac. Emotiva support suggested I get the umik-1 and remeasure so I did but I got the same results. I also tried the test tone feature at 20hz and I’m clearly getting extension at 20hz and probably below. I can attest to this in real world playback as well. Hopefully there’s something stupid on my end that I’ve overlooked in my setup. For reference, I have 7.2.4 setup with 80hz crossover for my speakers, subs set just past 12 o’clock on the sub gain, and ~9 o’clock on the sub crossover knob. Again, real world playback sounds good but I’d really like to use Dirac for bass management below 200hz so any tips would be greatly appreciated! How are the subs setup in the processor? Dual Mono? Mono? Have you measured with REW while using the USER Equalization slot instead of a Dirac slot? You can use this as a comparison. You can test the subwoofer at higher frequencies if you set the crossover in the processor for a Small speaker, say, the Right Surround, at its maximum of 200Hz then turn off the amp for that speaker and leave the subwoofer on. When you select the SR in REW it will then measure the sub up to 200Hz before rolling off the frequency. I use an HDMI cable between my Mac and the processor so I get choices for a 5.1 speaker setup. Also, try one sub at a time, then both together. It's amazing what can happen with phase cancellations. |

 have time to try with music and may be too rolled off, but for movies at volume this made a huge improvement. First, no dirac in red vs the old target curve (old was a slightly modded harman 6db but basically harman), note the hf boost above 1k but specifically between 1k - 3k there is an extra 1-2 db right there, I bet that is part of the problem. All the measurements are the average of the front three speakers by the way. Swept each one and ran the average and used that, helped a lot to cut through the noise and see the big picture.  I just cranked away at the target curve until the hf calmed down to more like my no dirac rew results, had to drop it a lot actually.  Original harman curve rew result vs final curve  Final curve by itself. Huge improvement in movie sound vs original curve, ran out of time to watch more but sounded much better and not harsh  Finally, no dirac vs new curve, it is the matching up of the hf response that helped so much. And look at that 50-400 improvement, that's pretty cool.  |

How long after submitting the Emotiva/Dirac registration (https://emotiva.com/pages/diraclive) should I be receiving the Dirac activation key/license?
Never mind, I figured out that I do not receive a license key after registration.

^^^^^^ What he said. As marcl has suggested, you can run a complete Dirac session but make the last mic position at the MLP, then immediately run REW with the mic unmoved from the last position which is the most critical. If it's easier to understand, start with the mic in the MLP position, run through all the other positions, then re-measure the MLP position, same difference. I am now using Dirac for two channel music, first time I've been happy with it. I just use it for frequencies below the 300Hz crossover of my Mains, so I dragged the upper curtain down to around 270Hz so only the woofers are corrected. I picked a point where Dirac wasn't doing much correction. I tried 400-500Hz before but Dirac was still sucking the life out of the experience. So as long as I keep Dirac away from the stat panels things are good! |

Hi all, Firstly -just finished all 157 pages. Big "thank you" to everyone who has contributed here to help our understanding of Dirac as done by Emotiva :-) I have a question and a contribution.
So - 7.2.4 (7 = all electrostatics) 2 JBL Cinema subs (https://jblpro.com/en/products/4645c)
First - I am planning on using a DBX Venu 360 (https://dbxpro.com/en/products/driverack-venu360#downloads) rather than a miniDSP for sub/bass management. As I'm considering RMC-1 L/R out =large - all other speakers = small) ; running L/R fronts into V360 - split to mains and subs. Then adding RMC-1 Sub3 out = LFE to V360 input 3 and adding that to the 2 subs. So all bass below the L/R fronts is in the subs for 2.1 playback and LFE goes there too for Cinema use.
Now I'm sure there's a really good reason why that won't work - so please enlighten me :-)
FYI - I can run auto corrections; time alignment delays; EQ PEQ etc etc for the Subs and mains in V360 - but will probably just add LPF/ HPF and let Dirac sort them all out.
Oh and here is a copy of my notes from this thread (NOTE - they are exactly that -just notes! stuff I like/or want for reference later - if they are not enough for you - make your own :-) But I would respectfully suggest they capture most of the important points discussed - and in only 58 pages instead of 157 :-).
Notes -updated to latest version of first 3 posts + links.

If I understand correctly ... this will work, and is essentially what I'm doing. L/R goes to the fronts full range and to the subs below a crossover. LFE goes only to the subs directly. Bass management for all smalls below their crossovers goes to the L/R fronts, and then to the subs only below the L/R crossover. If this is correct, then there will be just one problem. The bass management for the smalls below their individual crossovers will go to the L/R fronts in mono, but because it plays through two speakers the level of the bass will be increased. ttocs and I have been chasing this for months and it is an issue that needs to be fixed in the processors when more than one speaker (whether large or sub) plays bass management. The increase will be around 3-7db. The good news is when you run Dirac on the L/R it will see the fronts with the subs and give you a nice transition. Here's what my system 7.1 looks like after Dirac.  Also, I use a miniDSP the way I believe you're using the DBX. I've tried doing some PEQ on the subs, but I always go back to just letting Dirac do the whole job as you suggest. |

Well I have a lot to do ...I'll put up REW readings as I go 😁
Thanks Siggie - it's been a long time in the making.
I'm really interested in the way Dirac handles the electrostatics

I've got a fair amount of room management but I've put off further treatment until all the REW work with the RMC1 has been undertaken. This board has saved me so much time and effort - so once again - thank you everyone here.   |

I'm really interested in the way Dirac handles the electrostatics Dirac can be a little over-sensitive with the rear wave causing one or two problems. First is polarity can be switched, and the second is how Dirac handles phase in regards to if something can sound pulled to the left or right. My problems were solved with treatment for the Right speaker which is in a corner, while the Left is in the middle of the wall. I already had treatment on the Front wall, but added some on the Right wall to squelch the problems. One way I determined where polarity issues were being picked up was to do single point mic placement runs of Dirac. My polarity issue was with mic locations farther to the right, so this ended up being a reflection at a slight angle to the right wall and was easy to fix. |
