I could be wrong here, but the idea of MULTIPLE measurement locations may help with a null.....chance of measuring a null at the same frequency from 5 or more locaitons is slim.....
But gets more possible (not probable) as frequency drops.....Which I think is one of the problems measureing very low frequencies....

I could be wrong, as I can't enable Dirac Live right now, but doesn't the "Detected Range" checkbox show you the full range of measurements in a shaded area? That should give an indication as to whether a null is detected at all measurement positions. |

It is my understanding that for the XMC/RMC platform: 1. Emotiva has always planned to DLBC-enable the platform 2. Dirac must create and provide DLBC code to Emotiva, which Emotiva must incorporate into firmware, test and release 3. Customers must purchase DLBC as an option from Dirac I think that customers should expect the courtesy of a time frame for DLBC, so that we can make informed decisions. I would hate to switch to a another AVR only for Emotiva to release DLBC. In the very least, I think that we should at least be informed if Emotiva has a contractual commitment with Dirac to receive DLBC, because Dirac is probably pretty busy releasing product for Pioneer/Onkyo, and if we are depending on Dirac to deliver DLBC whenever they have time, we may never see it. If anyone is waiting for Emotiva to release DLBC then I’d recommend you move on and save yourself the angst. I come to these forum once a week or so to see if there is any news on DLBC. It’s been almost 1.5 years since Dirac was released. Almost beginning to think that Emotiva is just not admitting that DLBC will never come to see the light of day but still hoping it does since I have the XMC2. |

It wouldnt' kill me to hear that 'a null' was detected at each position, just not at the same frequency at each...... How many positions does DIRAC recommend for a 'full run'....?? |

I might have been wrong, I think it’s the “Spread” option that shows the full spread of all measurements for a speaker. The number of positions depends on the focus selection. The full doc has the information. Also you can view the measurements after measuring each position.  |

I didn’t see that one in the BBcode editor, otherwise I would have used it. It is deserved though, I should have included that I was copying the manual. |

I didn't see that it was from a manual and not within an app.  Another thing that I’ve had to remind myself is that especially with narrow and deep nulls is that often the graph looks worse than it sounds, especially if a null only occupies a fraction of an octave- 40 and 80 Hz are an octave apart. www.engineeringtoolbox.com/octave-bands-frequency-limits-d_1602.html |

Dirac recommends atleast 9 positions.. Each point no less than about 2 feet from the MLP. Atleast a cube like measurement of 3feet/1m. But no position other than MLP is set, all the others can be anywhere really. It needs point above, under, front, back, left and right of the MLP. This is not always possible, like if you have a sofa or a big chair with a high back. Dirac makes the best of what it gets. They have said it could work with as little as 5 positions also, but then it will not be able to do its calibration in the best way. The more you measure the better Dirac does it. But there’s also a point where doing more measuring points makes no real difference.. |

NINE positions sounds VERY reasonable. Next up, IMO? RECORD KEEPING to the 1/4" level for X, Y, and Z positions......
Use one of those laser levels IF you got one. Draw a plan of the room, too.......TAKE Careful Notes.

Not sure if you will get an answer or update, but worth a try. |

I just don’t know anymore. My unit now has less than 3 years of warranty left. |

Any news, good or bad, is better then silence… |

I'm getting ready to do my first-ever run of Dirac, using my XMC-2 and Macbook Pro. I'll be honest, I'm a little nervous about the whole thing because it seems more complicated than room correction software I've used in the past, but I know the results will be worth it if I do it right.
1. Is it necessary to use the ethernet switch that came with the Dirac kit? Can I forgo it if I have enough open ports on my WiFi router to plug in the XMC-2 and the Dirac interface box?
2. Is there any benefit to creating a Dirac account?
3. Should I set speakers to small/large and set crossovers as appropriate before running Dirac?
4. I was wondering about setting levels/distances before running Dirac, and I do see this in the FAQ at the top of this thread: Q: Should I set my Speaker Levels and Distance before running Dirac?
A : Dirac ignores both the level and distance settings when it takes measurements, however there is a User Slot where distance is in effect.
What I'm not sure I understand is the "User Slot where distance is in effect" part. Can anyone elaborate on that?
5. Assuming that I should set speaker distances before running Dirac, would it be best to do that with a laser distance measuring tool? Does anyone have one they recommend that's as inexpensive as possible while still being accurate for the purposes of measuring the speaker distances?
6. Are there any other noob pitfalls I should be looking out for as I do this?
Thanks so much in advance.

You can use your own switch as long as the processor and your computer are on the same network. 2. With an account you can report bugs and get a response. 3. Dirac ignores speaker size and crossovers, so it doesn't matter. 4. The User slot is not Dirac, it's for using the PEQ filters. Distance and Levels are in effect. 5. Dirac sets the distance for you, so no need to do it unless you use the User slot. 6. Look at the first post in this thread for updates on how to set levels. Published tutorials are mostly out of date due to updates Dirac has done in the past year. |
