Quick question. Should I set the levels of all speakers to zero before running Dirac? Before or after. Doesn't matter. Dirac internally zero's them when running measurements but afterwards adds your level settings to it's results so it doesn't matter when you do it just that you do it. |

Changed my curve for the bass on my fronts an subs. Put slow drop from 40hz to 30hz then quite a steep drop from there on. Almost no bass lower than 26-27hz.. This is only for my, now music only, second preset. Wow it really makes bass much cleaner when using subs with music.. Doesn’t really lack anything in most music.. It makes the subs sound less like subs.. Especially as mine are ported and with this curve I stop the sub from extending the bass..

Quick question about subwoofer test tone level. I have problems with the level setting. When using my XMC-2 without Dirac, just level ,distance and bass crossover adjustments done, my Sunfire sub volume knob are set to zero db gain. When using Dirac version 3.1.1, for a 2.1 set up, I have to drag the sub slider all the way down to -12db and turn the sub volume down a 1/4 turn, to avoid clipping during measurement sweeps. At the same time my front speakers slider are all the way up to get decent levels. After new filter are installed in XMC2 and I test it with some music, I have to turn the sub volume knob back up to 0DB gain to get some bas.
This is the first time I have run Dirac since new Emotiva FW 2.3 and Dirac 3.1.1, so where are the test tones generated? Computer software or XMC-2 hard ware or the interface box?
I use to have a XMC1 with full Dirac and that one was very easy to get a good sound out of. This new generation are just to sensitive and unpredictable. One measurement session can produce a good result, the next one can be crap. Even if its done in the same manner with similar mic positions and noting ells have changed.

One measurement session can produce a good result, the next one can be crap. Even if its done in the same manner with similar mic positions and noting ells have changed. The internal test tones in speaker settings are done by the processor. In the Dirac app it’s done by Dirac through software. Do you have the same issue when setting up internal non-Dirac level settings? You could try a factory reset as you will pretty much restart your speaker setup anyway. I have my subs at about 11.. From a 7-17 gain/volume. This gets me about the same volume as my SVS speakers in Dirac. They are all 88/87dB sensitive. |

Are you using the Emotiva supplied EMM-1 mic? @ swedishcaveman ... Are you doing measurements after calibration with REW? Just wondering if the reduction in bass matches the reduction in volume during calibration. It's definitely true that Dirac 2/3 works very differently than Dirac 1 did in the XMC-1. Dirac recommends leaving the sub level slider all the way up and lowering the volume control on the sub to get the level set. If you start with the sub volume knob down a bit and raise the Master Output until the sub level is around -20db that's a good starting point. If you can't get your other speakers to at least -28db with their sliders all the way up, then lower your sub volume knob and raise the Master Output a bit. A couple iterations should get all the levels between -20 and -28 ... and that is good enough. BTW, what are the resonance modes of a Swedish cave, man?  |

I am using a UMIK-1 since yesterday and it made the level process even harder. I haven´t tried REW yet, need more time to learn. I am using an old Imac with a OS that dirac latest sw don´t support. I can install and run the sw but maybe there are some unknown issues. I will try to get an more modern MAC and rerun DIRAC. Thanks for all good info.

I can install and run the sw but maybe there are some unknown issues. I will try to get an more modern MAC and rerun DIRAC. Thanks for all good info. hmmmmm, in my case the UMIK-1 is easier to work with than the EMM-1. The UMIK-1 mics have less disparity between the loudest channel and the weakest channel, so clipping and signal to noise errors are less likely. I'd suggest trying what marcl posted above and see if that works for you. Meanwhile, here is a comparison I did of the EMM-1 and UMIK-1 about a week before the latest Dirac was released. I used a second UMIK-1 mic for monitoring the SPL with REW. The Left Surround is the weakest channel so the slider was left all the way up for this channel and all others adjusted for same SPL except the subs which are 4dB higher.  I found that targeting about -26dB was good for speakers, and about 4-6dB hotter for the subs so they are targeted for about -22dB in Volume Calibration. This results in speakers and subs being about the same SPL during Measurements. Look at the right side of the attachment for UMIK-1 settings that work well for me. Also note the SPL for the Measurements of both speaker and sub are almost identical with these settings. When speaker SPL is about -30dB and lower, there are signal to noise errors. I don't know how high the volume needs to be for clipping errors because I don't go above -22dB ever, it's just too loud. The range I use with a UMIK-1 mic is -24dB to -26dB for speakers, and -20dB to -22dB for subs. This works for both mics. |

I have read about people blowing speakers when doing DIRAC setup, so i was lucky my sub survived. I will get a new laptop and do a new test using the info you posted. Maybe using the highcut off on the sub will help. DIRAC sends a full range signal.So if i cut it above 100hz? |

Maybe using the highcut off on the sub will help. DIRAC sends a full range signal.So if i cut it above 100hz? The measurement levels just should not be that loud, so I think the sub volume knobs have to be turned down more. So for example (for you and for others to note) .... The ambient noise in my room at the MLP is 44dbC (I measure C-weighted to be sure to include the bass). My sub levels (knobs on the subs) are set so that with Master Output at -28 it results in the sub level -20 with the slider all the way up on the Volume calibration screen. When setting this level using the calibration sweeps on the volume screen, the sweeps measure 74dbC at the MLP. Then I set all the other speakers at -28db. Then on the Measurement screen when the measurements are taken, the sweeps range from about 65 to 75dbC ... the actual measurements. These levels work fine and are definitely not loud. And I think 20-30db above the noise floor is sufficient. Actually when I calibrate I usually turn off HVAC and the refrigerator which drops the noise floor a couple more db. |

If the SW you are trying to run is NOT 64 bit......IOW, it is 32 bit, you will have a problem..... Maybe DIRAC has a list or it is part of a FAQ? |

I've had other SW issues with the latest OS X versions. some of my old-standby SW is now just taking up space on my drive.
Like an older version of PhotoShop. And Office 2008 for Mac.
At least DIRAC seems to be updating and upgrading to account for the latest in OS mayhem.

Good DIRAC sound at last! My Imac have OSX 10.13, so I loaded DIRAC SW v3.0.0. IAW Dirac live changelog v3.0.0, they added unofficial support for MacOS 10.11, 10.12 and 10.13. Next I adjusted my sub´s high pass filter to 100hz, and low passed my Klipsch RF-63 tower speakers to 60hz, surround´s, rear´s and center to low pass 80hz. During volume setup before measurements I used values supplied by marcl and ttocs on this forum. -20db for the sub and -25db for all the rest. It´s a 7.1 set up no ATMOS. Mic gain 100% gave me -53db noise floor. I did an tight focus listening area measurement, using Storm Audio´s asymmetric mic placement pattern. Loaded a Harman6db curve to all channels.
The result are crazy good. Solid center stage, deep strong punchy bas and detailed surround effects moving all around my cave. I now realize that Emotiva Dirac user guide are the wrong way to go. As somebody wrote here, it is time for an update.

Quick question (Dirac newbie) - if I want to do a dB boost on the low end similar to Harman curve, should I just apply the booster target curve on the sub channel or apply that curve on all channels?

hi everyone, i own an rmc1, i would like to know is it possible to use Dirac Live Bass Control for multiple subwoofer by purchasing the separate license?
Thank you
