Try taking a spl reading for the speakers. Tony Speakers are level matched for my preset 1 setting and the image is about perfect. Take a spl reading during the Dirac speaker volume setup screen? Take a spl reading post dirac. You can modify the lecels in the dirac preset on the xmc. Tony

My speakers are only toed in about 5 degrees and they are 103" apart. The center image is perfect without Dirac but after trying it with Dirac the center image becomes fuzzy and unfocused. I get the same effect with both Dirac LE and Dirac Full and have used both the Emotiva mic and a UMIK-1. Does that 5 degrees aim your speakers' 0-axis directly at your ears when you are in the MLP?

Dirac Full for two channel audio always smears my center image and has a hollow sound after I run it each time. Is there a way to prevent that? If running stereo only I wonder what would happen if you ran only the sweet spot Mike position?

Tony I did check that and Dirac ran one speaker up louder than the other a little but I could not improve the image by putting them the same again. It kinda has an out of phase hollow sound after Dirac.

Run all 9 measurements in the same sweet spot?

They did not need much toe in too sharpen the center image. Understood. If you are in an experimentin' mood, aim them directly at the MLP and re-run DLCT. Off-axis speaker response even in the horizontal plane can be squonky and this would eliminate that as a possible cause. Jeff

Page ago I asked about IR external sensor for XMC.. Just now tried sensor from this kit goo.gl/Wp6pbA (bought it long time ago but didn't used cause of annoying wires and unstable work) - surprisingly it works, just plugged standard trigger cable to XMC "IR IN" and ir sensor female port, plus usb power into XMC usb port. However I'd like to avoid additional power cable, will XMC work with passive ir receiver like this goo.gl/a8Rwnc ? Tried to plug another trigger cable to XMC "IR OUT" and Oppo "IR IN" - also works, very good

I think it will boil down to if the XMC can accept a trs over a ts plug Tony

The XMC-1 will NOT work with a totally passive "IR eye" - it requires the buffered signal provided by the "little black box". Page ago I asked about IR external sensor for XMC..

Tony, In Dirac Full has it been your experience that you achieve a better result by adjusting the level of the subwoofers with the sliders in Dirac or do you agree with the Dirac manual's recommendation that subwoofer levels should be adjusted with the subwoofers own level controls?

I set the sub to 50-75% and use the slider gain for the reminder. (I want to leave some headroom in case I need it.) Tony

The powered Xantech IR hubs stuff I recommended to you will probably be more reliable in the long run, but at that price I don't blame you for buying that ebay kit. The Xantech IR receivers work with a powered Xantech "IR hub" and come with filters for various issues like IR interference from fluorescent/CFL lights, plus the Xantech hubs have LED's for debugging things, etc... It is what professional integrators/installers would use in the US, but a little pricey. You can wire them up to almost any home automation system too. I have the Xantech hubs hooked to a URC MSC-400, and even a Global Cache GC100 network based IR controller. www.amazon.com/Xantech-ML85K-Proof-Micro-Receiver/dp/B004ED8CHMPage ago I asked about IR external sensor for XMC..

I get the same effect with both Dirac LE and Dirac Full and have used both the Emotiva mic and a UMIK-1. Your first measurement must be absolutely dead center on the listening position . Consider redoing the measurements: 1. With extra care taken to position the mike for measurement 1, consider searching for the right position for measurement 1 (try fewer measurements so you do not go crazy listening to sine sweeps) 2. If the above fails, consider reverting to the Emotiva mic for a repeat of number 1. There is a possibility that the Umik could be out of calibration. If the Emotiva mic improves things it may be time to buy a new calibrated mic. 3. Also consider reviewing what your computer is doing to the UMIK gain. If Windows make sure AGC is off and gain is up. If Mac make sure Audio MIDI Utility is applying unity gain. Just a few ideas to try. Nam

They were. Thanks. I have the same issue. Very muddled phantom center with Dirac. Perfect without. Other than that, Dirac improves the room greatly.

Tried to use XMC-1 with power regenerator (like PS Audio Power Plant) and got amazing results - clearer sound and much better microdynamics, very cool. As I live in Europe I have 230V@50Hz in wall socket, however regenerator allows to ajust frequerency. I had set 60Hz and hear some difference - wonder why? XMC can work both with US and EU power standards, but should it sound better with US power standard due to higher frequerency? And is it safe to try higher value, regenerator allows to increase it up to 120Hz
Thanks etc6849, but its too much for IR sensor.

They did not need much toe in too sharpen the center image. If you have a SPL meter check the levels of your front left and right speakers with Dirac engaged. If they differ your center image could move off center, lose focus , become fuzzy, etc. If the levels are dissimilar match one to the other and see what happens.
