I'm not shoure, just reset the xmc-1 checked the mic file and run Dirac again.

Not 100% what fixed it, but a factory reset, hard boot, toggling reference stereo and dirac rerun cured the trouble and doing it all twice while screaming obsceneties seemed to clear it right up.

"... while screaming obsceneties seemed to clear it right up." Tony Tony, I think this is the part that really did the trick for you.

Tony Were you standing on your head at the time too? If so, that's what really fixed it... along with a couple of choice obscenities.  |

I've had this same issue, was driving me nuts. My first Dirac calibration run was fine, then more recently, all my runs have resulted in sound being steered to right channel. Some of those runs were with Dirac LE using the default calibration file, some with Ansat's calibrated file, and most recently with Dirac Full (also with Ansat's file). Emotiva support has advised me to run the calibration again if I see the issue, though I've been having different issues that's prevented me from playing around with it more.
I'm planning on getting a calibrated UMIK, to see if that does in fact resolve the issue.

I played around a bit more with this today, and did three calibrations: one full one, and the other two only one measurement at the sweet spot. All three came out strong on the right channel (2nd by ~7 dB, the 3rd by ~4 dB). When checking levels at the beginning of calibration, I can see that the left and right speakers measure about the same. But looking at the final graphs, the right speaker is indeed about 5 dB below the left speaker curve. If I use Reference Stereo mode, or one of the default presets, both channels measure the same level.
Out of curiosity, checking the levels of the surrounds after Dirac calibration, they were all about 3-4 dB hotter than the fronts, but otherwise all balanced. As a temporary hack, I just turned down the level of the right channel post-calibration, music does feel more centered, but tonally the right channel sounds quite different from the left (like some treble roll off).
I'm hoping tonight to experiment some more, when there's less street noise (possible that's affecting my measurements), and I'll try a near field measurement to see if maybe it's effects of the room. I also have a spare EMM-1 mic I can try for comparison.

I finally got this sorted out... It ends up the channel imbalance was being caused by my calibration procedure (which I was being very consistent with, explaining why the problem kept reproducing no matter how many times I redid the calibration). I started by doing a couple near field calibrations (microphone about 4 feet away from speakers, almost dead center, so practically no room interactions). These were fine (no channel imabalance). Then I tried a single measurement, at the listening position, also no problem. But as soon as I did all 9 measurement points, the problem reappeared. At this point, I made an observation: my couch is An L-shaped sectional, and the microphone is rather close to the surface of the couch (since its roughly ear level). My theory was that them cushions on the side of the couch that juts forward, were boosting the sound when the microphone was near them (for measuring left side of the couch). WHile my ears don't hear a difference, I believe that's just a psychological processs. If I were to put my left ear a few inches away from the couch cushion, I wouldn't suddenly perceive it as being louder on my left side, although I'd imagine a microphone would). So, I took the cushions off their couch, and made the 9-point pattern much tighter, taking care to keep the microphone at least a foot from any surfaces of the couch. And voila, the imbalance was gone. Did it one more time, to make sure it wasn't a fluke.
So, moral of the story: 1) keep the microphone a good distance away from any surfaces, especially if they're reflective, and 2) the microphone can pick up and hear things in a way that your brain may not.

Interesting. I was just thinking about this yesterday. I am about to get a new love seat and where it will be placed in my room, the sweet spot will be in one of those two seats. I was wondering if the cushion side would prevent me from proper measurements. On the the other side of the sweet spot is a hard wood floor. Thanks for these posts.

I think I figured it out. It's clearly a bug. I ran into this problem today and last few days. I retook measurements a few times, etc. That didn't help. Oddly it was driving me crazy because i knew it wasn't microphone measurement and placement issue because one time I uploaded the filters it worked perfectly and I took them again very carefully with the same result. I couldn't figure out what I was doing differently this time or that time.
As suggested in this thread, I went ahead and reset my XMC and voila, it worked. Still scratching my head, but whatever, I'll just keep playing with different filters. On the second upload. the same thing happened - right channel significantly louder than left. And then I figured it out. If you reset your emotiva and upload the filter first thing after reset, it works correctly. If you set your speaker sizes (in my case large + subwoofer and nothing else), it does not upload correctly. Same happens if you change your speaker settings after the first successful upload. The next upload won't work correctly. However, changing the speakers to correct settings if you uploaded the filter first does not create this problem. Hope this helps someone.
I'm actually quite pleased with how Dirac sounds. Originally I preferred the Reference Stereo mode and I'm no longer sure. The imaging is wide and instrument placement is still as precise, if not better than without Dirac. This is using a pair of KEF Blade 2 powered by a declare ZMA tube amp connected to the XMC-1.

Yep, that sounds like a bug in the software and your very specific observations may help Emotiva and the Dirac folks track it down. It's a good explanation for why the incredibly annoying advice to "reset to factory" defaults" helps. You're putting the system back into the most likely state that the QA folks are using. They need to broaden the set of states that they test with.

Also, for reference this was done on a Mac 12 with MaCos Sierra 10.12.2. I will test it out on the bootcamp windows 10 version in the next few days.

When you say change speaker setting what changes are you referring to exactly. Size or Crossover or ? |

Has this been resolved? I have had this problem since day 1. My left channel is hot compared to all the others

I know this is an old thred. But, I am having the same issue. After running Dirac multiple times, my front left speaker always plays too low. This is the mic calibration file that I used, EmotivaMicCalOA.txt. Is this the correct mic file or is there another that I should use?
Thanks,
JP

The "full" version of Dirac 1.1.0 and I'm running it on a Mac.

The "full" version of Dirac 1.1.0 and I'm running it on a Mac. When you run measurements are all the sliders in the "green zone"? Have you compared the graph for the speaker with low volume to the graph for the other front channel speaker? |

All the measurements where in green zone. I haven't thoroughly checked the graphs; I'll do that later this week and will upload some pictures.
