leonski I believe the only one that's "required" in a specific order is the first sweep in the MLP. While Dirac will progress through the other locations and tell you where to move the mic and start measuring, you can override that and simply click on the location, then do that measurement. To complicate things a bit more, you don't even really have to use those positions. I don't recall if it was in this thread or in the thread on AVSForums, but someone posted a link to the Storm Audio basic Dirac instructions and it clearly shows a completely different pattern for the measurements. If you stop before taking all the measurements, I believe you can still click the button to create the filters.

Which would APPEAR to mean that the system treats ALL measures after the first, The Same.

And you can go back and rerun measurements. And that includes the MLP, as long as you specify it in the diagram. I sometimes rerun the MLP so that the mic is in that exact location when I run REW after calibration. Dirac folks have said in interviews that the order and exact position of the other measurements is not part of the algorithm. But they do stress that having more measurements makes the calibration more accurate. I can tell you from my experience that once you proceed to filter design you should not go back to measurements and take new ones or add/delete. I had an exchange with Dirac support on this and they agreed it may be that preprocessing that happens as you proceed to filter design cannot be completely undone if you go back. So the safe thing to do if you might want to go back to the measurement stage is save the measurements as a project before proceeding to filter design. Then save the project again after filter design. That way you can always reload the measurements and it will take you directly to the measurements screen. |

I am having an issue with Dirac not registering the correct subwoofers that I am running. I am not sure what am I doing wrong and if someone can help me. I just added a second sub and bought a dual core 2.0. I have the dual core set up as dual mono with one XLR running from the left subwoofer XLR on my RMC-1 to the dual core, two core to the subs. I have the RMC-1 set to mono. When I go into Dirac it is showing both a right and left subwoofer and I cannot for the life of me get it to show only a single mono subwoofer. When I run level calibration I get a test tone out of both subs on the left sub and nothing out of the right sub, same thing happens when set to dual mono in the RMC-1. My issue is that anytime I run Dirac now I get the low noise floor error, which I believe is due to it not playing a test tone out of the right sub. How can I fix this so that Dirac is only showing the left subwoofer? I tried everything I can think such as hard rebooting the RMC, closing/reopening Dirac l, choosing a different preset etc…. to no avail.

If I understand what you want to do correctly, I think this is how you want to set it up (I know nothing about dual core's so keep that in mind): 1. Run one sub output from the Center Sub output to the dual core 2. From the dual core run you sub cables to each individual sub 3. In the RMC-1 disable l/r subs and only enable the center sub output as mono |

I was under the understanding to not use center sub from the manual but looking back at it now I misunderstood it. I will give it a try! |

Do bear in mind that, since Dirac doesn't adjust the response outside the curtains, at the actual curtain points, it must "bend the line inside the curtains to meet the line outside the curtains". This MAY result is significant differences in how the filters near the curtains are calculated if you move the curtains.
This is one of the reasons I always ”steer” the bass in the right direction (down) at <20-25hz. I usually set the curtain at 10-14hz depending on speaker. I notice even Dirac will show a spike sometimes if the curtain is in the wrong place. In my room this is worse as my three front speakers and subs have a HUGE peak (+14dB) at 24-25hz. The good thing though is the bass extension I get for free.. Just letting Dirac attenuate it.. My speakers having to work less in the absolute low end. But without Dirac or any PEQ it will not sound nice at all.. So that’s probably why I’m not so fond of listening to Reference Stereo with low bass heavy music. Yes, I know most music won’t extend lower than 30hz. But this peak is 10hz wide then I have a dip at about 35hz (-4 to -7dB depending on speaker) and another peak at 47-48hz of about 5-7 dBs.. So I have a rollercoaster in my low end.. Which Dirac fixes amazingly good. Yes I know. I usually put in a lot of time to get this perfect.. My curve always meets the measured frequency outside the curtains. That’s also why I mostly use Dirac full frequency with the curtains.. Makes it a lot easier. |

Positions to either side are #2 Other positions are 3rd......something along those lines. |

The measurements around the MLP are so that Dirac can determine - by comparing the measurements - which response anomalies are minimum phase or non-minimum phase. Having determined that, Dirac designs the filters to correct the minimum phase anomalies. The result gives you an optimized response that is as good as they can make it at the MLP and as close as is possible in other positions. But it does not optimize the other positions by weighting those measurements. |

This run with Dirac sounds much better with the dual core set up the correct way. One anomaly that I find odd though after running Dirac this time is that all of a sudden my volume has went from full numbers such -55.0 on the display and now is displaying half numbers like -55.5. Have had the processor for over a year and it has always ended in .0. Any idea why this would have suddenly changed? I hard rebooted with no change. |

That is a known issue after running Dirac but is easily fixed. Just run the volume all the way down as far as it will go and that's it. When you turn it back up it will be in .0 increments. |

Good feature for the masses. Good that you will be able to edit the curve after Dirac has suggested it. Hopefully this will arrive for the PC/Mac versions to. Even though I probably won’t use it. Would be interesting to see what Dirac recommends for my system though..  |

Interesting that Emo is not on the list of supported devices. I wonder why that is.
"Currently Dirac Live-enabled devices from NAD, Onkyo, Pioneer, Integra, and Pioneer Elite are compatible with the Dirac Live mobile app."

Not that I'd want to, though. +5channels I almost sure you need to support the mobile version internally like Onkyo’s.. Don’t know if the app connects by Wifi direct or if the app can be used in your own LAN. If this isn’t too much work for Emotiva they should add support for it for those that don’t own a computer/laptop that they can use with Dirac. |

I have a question about checking sound level after Dirac calibration. How do you guys do that? Do you play a special ATMOS or DTS-X disc that send white or pink noise sound to height or top speakers? If you use such disc, please provide a link for buying it. If you use your processor generated sound level, how can you tell if the Dirac calibration has been applied to that sound level from your processor?

If you use such disc, please provide a link for buying it. If you use your processor generated sound level, how can you tell if the Dirac calibration has been applied to that sound level from your processor? The broadest answer is to use Room EQ Wizard to measure the results after calibration. That will let you see the frequency response and impulse response corrections as well as the relative levels of each speaker. You can send band-limited pink noise from REW and use its SPL meter to verify that all speakers are the same level. The limitation is REW can only send to 7.1 .... it doesn't send signal to Atmos tops or any channels beyond 7. To measure the tops you can use Levels in the processor and the REW SPL meter or a phone app, etc. The Dolby Atmos Sept 2016 demo disc has pink noise channel selections for several Atmos setups. You can use that with an SPL meter to measure all the channels. Remember that if you set the Levels in a Preset to anything but 0.0, that Level adjustment will be applied in addition to the Dirac level adjustments that it determined during calibration. |
