the soundstage was off center Mine is the same, centre is shifted well to the right. Will re-run and look for a much better result.

What I ended up doing was raising my right speaker level by 2.5 dB and lowering the left speakerβs level by 2 dB. This seemed have done the same trick - so the imaging makes sense now and it looks like I preserved the excellent post Dirac the sound quality . I hate running Dirac so I plan on leaving it alone until I add a couple of ceiling speakers. 7.1.2 will be it in this room.

With the crashes and the off center, I'll wait for another Dirac update!

Reference stereo was fine - it didnβt shift.

Mine shifted in both, but it only took 1db to re-center I've been chasing a problem like this for over a month only with my right channel, while doing a few Dirac calibrations over and also changing some room treatment. I think it's a combination of things, but definitely related to Dirac. In my case adjusting the level of the lower channel doesn't completely solve it. It's an imaging issue as well, and I suspect it's phase related. The "quieter" channel seems less distinct, a more diffuse image.

I looked and still looking but does anyone know where I can get my Dirac license key? Finally sitting running DIRAC using my kit.

I did. Also not sure why XMC does allow me to enable DIRAC. Shows unavailable.

I did. Also not sure why XMC does allow me to enable DIRAC. Shows unavailable. So, I assume at this point you have checked to make sure your XMC-2 has internet access to make sure it has an IP Address and the network card it working. If not, do the follow...either... 1) Look on the back side where the internet cable plugs in. If there's not light on the port you are plugging into, that's 1 problem... 2) OR check to see if you have an IP Address. (Go into menu, setup, and then I think it's "information" and continue on until you see the network info...if you show 0.0.0.0 for IP address...you are not connected to the network. What I personally found is that the Emotiva instructions for using Mr. Ed (the EDNIB) are not clear and will not reliably work. EVEN IF Dirac has activated your license, the XMC-2 MAY NOT allow you to enable Dirac. BUT...what HAS reliably worked for me it to do the following: 1) Have the XMC-2 and the PC that has Dirac on it plugged into the Emotiva-provided switch with the switch on and XMC-2 powered off. (The switch SHOULD show a red light and also a green light for the port you have the PC plugged into if the PC is powered up.) 2) power up the XMC-2 and wait until you see it's connected to the internet (check for green light on switch for the port it's plugged into, then check for presence of an IP address in XMC's "information" menu). NOTE: IF there's no green light...power down the XMC-2 using the back switch or holding the front button down until it's fully shut down...then power it up. At that point, you should see a green light on the Emotiva-provided switch for the port it's connected to. 3) connect Mr. EdNib to the switch and power up Mr. EdNib and wait a minute or so until the lights on Ed's ports come on. At this point, the switch should be showing a red light (for power), and green lights for the ports into which you have the XMC-2, the PC, and Mr. Ed plugged into. At that point, you should be able to go into menu/setup/preset 1/Dirac and enable it. And after that the XMC-2 will be unresponsive and you need to go into the PC, launch Dirac, and run it. I hope that helps. Tag me in what happens from this. I want to know if that works for you or not. Mark

Thanks Mark, I will try in AM. Going watch TENET without correction... .

Removing measurements. I had an idea a couple weeks ago that I could do a 17 position calibration, and then go back to the saved project and make new versions by removing measurements to create filter sets from different combinations. The comparison would be valid because the measurement positions would be identical. Well it wasn't that simple. Once you finish measurements and proceed to filter design, Dirac does some Preprocessing that can't be undone. You can't go back and remove measurements and have it go back through the Preprocessing stage unless you also re-measure at least one measurement first. But there is a way to do this! Do the 17 position measurements and BEFORE proceeding to filter design, save the project. Give it a clever name like "Before Preprocess". Then, to create several variants with the same measurement set, load the Before Preprocess project, remove some measurements on the Measurements screen, proceed to filter design, and save that project. Note that you must leave the MLP measurement alone. Now you can load several different measurement patterns and evaluate - through listening and measurement - which is the best for your listening environment. Then in the future if you need to do a calibration you can just replicate the one best measurement pattern. What I found in my room was that the high measurements gave better results than the low measurements, and that narrower patters were better than wider. The "better" patterns were all better than the full 17 position set. So I settled on a 5-position pattern with the MLP and four positions in a square above it about 18 inches apart. This works for my room because there are just two of us and all serious listening and video watching happens on the couch with our heads pretty well centered a foot either side of MLP. p.s. I seriously wish Dirac would have a button in Filter Design that says "Save Default Groups, Targets and Curtains". It's such a pain to have to pull speakers into separate Groups and manually load 7 Target curves and then adjust 14 Curtains ... EVERY time I do a new set of filters.

marclThis is VERY good to know. I started keeping myself of personal list of "stuff they don't tell you or that you really have to dig to find". I'll be adding this tip to my list! Mark

marcl This is VERY good to know. I started keeping myself of personal list of "stuff they don't tell you or that you really have to dig to find". I'll be adding this tip to my list! Mark Thanks Mark (BTW it seems we have at least three "K's" and "C" in these Emotiva threads ) I should add a caveat .... I exchanged a few emails with Dirac support on this topic and was unable to get any specific information ... just a warning that "beyond some point" you can't go back and remove measurements. Interestingly, you can go back to the Arrangement screen, but if you try to change to a different arrangement after having done the measurements it presents a warning screen suggesting you let it remove all the measurements so you can take them again, or keep them (not recommended) ... and it says the positions in different arrangements are "not equivalent" ... and some generic warning of unpredictable results. All that effort with no meaningful information on what you can or can't do. And in the end it's as I stated above ... if you have gone past Preprocessing you can't remove without remeasuring.

marcl I agree with your measurement observation. I did do the 9 pt and it worked like a charm with the exception of the soundstage being off center. I had to do the - 2dB +2dB. Right now itβs as good as itβs sounded. But I did a 13 point measurement for when the family wants to watch a movie.

the soundstage was off center Mine is the same, centre is shifted well to the right. Will re-run and look for a much better result. Ran a new calibration with .13 and everything now great, perfectly centred imaging.

I will give it a try. Which one did you run? 9, 13 or 17 point measurement? The 9 point measurement is what Iβm interested in for music. Itβs unbelievable how good it sounds. The 13 point smears the image a bit.
