The XMC-1 treats the left and right subs as separate (the RCA and XLR for each channel carry the same signal). If you select MONO SUB, only the left sub output will work. If you select STEREO SUB, they will be considered to be entirely separate. If you select DUAL MONO, then both subs will be calibrated separately (including distance settings), but afterwards will be fed a summed mono signal. Apologies for bringing up an old post, but a search only yielded two responses for dual mono subs, and this was the only relevant one. The manual is a bit ambiguous; it mentions the sub modes for the "regular" presets but is not clear (perhaps just to me) if they also apply with Dirac Live. I would like to confirm the information above for dual mono subs using Dirac Live (full) and the XMC-1. I recently picked up new speakers and moved the listening position. Being lazy and/or swamped at work, plus I am not sure everything is in its final position yet, I don't want to spend the time to re-align my subs if I can avoid it. I have a four subs, a pair up front, and a pair in the rear. The front two are roughly equidistant from the MLP, as are the rear two. I adjusted the phase (delay) in pairs and then ran them as (from) a single mono feed. Now, I would like to separate them and run dual mono with the front pair and rear pair aligned separately. That will allow me to tweak the listening position as I dial in my new setup whilst accurately compensating for the sub pairs' distance to the MLP during multiple Dirac Live runs. Will this work OK? Second question: In this scenario, will the two sub (pairs) appear in Dirac Live's listing as two individual subs, or will they appear as a single sub and the XMC-1 will still accurately compensate for the different positions relative to the MLP? Thanks, Don It will work and they appear as 2 seperate subs in dirac. |

Follow-up: I did try dual-mono and it worked well for me. I grouped the subs so they'd have the same target curve. Still wish DL and Emotiva crossovers would play nicely together (need to pass the response after crossover to DL) but in this case it worked like a champ to align my two pairs of subs with the mains.

![]() Hi, I am newbie to XMC1 and Dirac, today for the first time I tried Dirac, attached is before & after chart. As a newbie I'm not able to interpret the results fully. Please let me know how the results look. Thanks |

![]() Hi, I am newbie to XMC1 and Dirac, today for the first time I tried Dirac, attached is before & after chart. As a newbie I'm not able to interpret the results fully. Please let me know how the results look. Thanks Looks good for those three speakers - it is using the standard Dirac "target curve" - a term used to describe that slanted response curve you see. Did you have rear speakers connected? |

There really is not much to tell other than DIRAC is doing what it needs to do to EQ the room and try to compensate for the lack of room treatments. This is a field that can be quite involved depending on how much you want to delve into it, but at a minimum I would start by learning what these graphs mean and how to read them. Once you are more comfortable, then you can use the full version of DIRAC to tailor the sound more based on your preferences and the room acoustics. In the mean time, enjoy those bad boys!

The thing that has me wondering is that your before analysis shows some big dips. To adjust, DIRAC will cut the higher peaks and attempt to lower the valleys by boosting them. This can be volume-limiting overall or create issues as the boosted ranges try to keep up. Are you getting sufficient overall sound level afterward with no distortion? If so, cool. If not, try to tame the dips with room treatments and re-run it.

namikis goozoo klinemj- Thanks for your responses, I don't have rear channels, its just Left/Right & Center. 1 other questions: before I ran dirac I measured using SPL meter and set speakers levels in XMC1/Dirac Speaker preset. After the Dirac process completed all 3 speakers level are set to 0db in XMC/Dirac Preset. Do you know how it got changed? or this is expected as part of Dirac process? Thanks. |

That is normal behavior. Just ran Dirac last weekend for first time in a year. I moved and never reran Dirac just used what i had LOL. Man does it ever sound better . If you did it right you should not have to change by more than 1 or 2 db.I always check the levels after a run just for peice of mind.

Do you think that Mobile Dirac Live App will be avalaible on our XMC-1 ?

Do you think that Mobile Dirac Live App will be avalaible on our XMC-1 ? Hoping so. I will inquire at emofest. T |

I need a hand. Just switched to a new Windows 10 laptop. Installed Dirac Full, and it connects to the XMC-1 perfectly. But I keep getting an error, "Cannot open recording device"
I'm using a UMIK-1 that works perfectly on my desktop PC. And it's recognized by Windows and when I click the "Listen to device" in Control Panel, I can definitely tell that it's hearing me as I talk. The LED is on, and all other microphones are disabled.
Dirac is running in Administrator mode.
Any suggestions?

For reference, I have a UMIK-1, and just used it with a Windows 10 Laptop and Dirac today. |

I can use the mic to record my voice. The mic is definitely working and works perfectly with Dirac on my Windows 10 desktop.

I would try another 3rd party app like REW suggested above. My UMIK also works fine with Dirac on my Windows 10 laptop.

Make sure you are running Dirac Live Full for Emotiva and not Dirac LE versions. You can have both installed in the same laptop so you must be pressing the Dirac icon of LE version instead of Full version. The LE version only works with the supplied Emotiva mic.

I only have full. And Dirac detects the UMIK-1 on the 2nd screen where you indicate the config file.
The Device Manager settings are exactly the same as the laptop as the desktop.
Dumb question - do I need the Windows 10 drivers that allow USB connectivity to the XMC-1? I saw that during a Google search, but I thought it was a crazy theory, but the author seemed to be confident in what he wrote.

No, you don't need the USB drivers for the XMC-1. That wouldn't make sense, since you don't connect the laptop to the XMC-1 via USB when you use Dirac.
So, if I'm understanding correct, Dirac actually recognizes the UMIK-1, but won't let you proceed because of the error? That almost sounds like a problem with exclusive mode. I wonder if something's grabbed the mic, and nothing else can used it. I'm not near my Windows machine right now - is there an exclusive mode option when you go the Recording Devices options? If so, try unchecking that and seeing what happens.

Update - I got it working, but it took some creativity, and (to me) points to a software defect in Dirac Full. Steps to resolve on Windows 10 Home: 0. Plug in the UMIK-1 microphone, Set gain to 100. The exclusivity options didn't make any difference. 1. Run Dirac as administrator (this alone should not be required). 2. Connect to the XMC1. 3. 2nd Dirac screen - make sure the UMIK-1 is selected and the configuration file is recognized. 4. 3rd Dirac screen - get the message "Cannot open recording device" 5. Go back to the 2nd Dirac screen. 6. Unplug the microphone. 7. Plug in the microphone. 8. 3rd Dirac screen - the help text is missing, but Dirac can now use the microphone. 9. Continue as normal. I had to think like a developer to come up with that solution  |
