Check your file for any trends in speaker response on the high end. I would expect to see better past the 3k mark with your quality of gear. As for the clipping, make sure AGC is turned off in the windows settings as it can cause issues.

If anyone gets miscellaneous clipping alerts (failed run) when testing it could be like me and set the levels too high. As in this pic, each channel's volume is locked together. Adjust the level on any of them and you are adjusting them all. So click on each one and only adjust the one with highest level to be in the good green area. Do not then adjust any others.  |

Tony I'm not sure why the highs were so weak although I often wonder if I made my room too dead for that range. I have dense carpeting on the floor, acoustic panels on almost all side wall space (R13 encases in wood frame and wrapped in fabric) and my entire ceiling is covered in Fabricmate Anchorage fabric over 1/2" homasote screwed to osb that is "floating" on foam isolation barriers. I'll check the AGC setting but not sure what that stands for. Auto gain control? I pretty much did a plug and play session and probably limited my mic positions to too small an area and I didn't vary the height very much (maybe 8" max) Scott |

I thought the target was the center of the green (-12) from what the instructions said. (right "help" pane of Dirac window) Will try these settings on the next run. Scott |

Scott I found this to be the case also. At first I thought each was independent, but they are not. So I got my first main speaker where I wanted it in the green, the next main was almost dead on, the center, surrounds, and subwoofer a bit lower. Everything worked fine though. If you up the output on the lower level speakers, the output will then go "over" on the ones you first dialed in. Not an issue in my setup. The center channel, (Thiel SCS3) sounds much better than it did with Pioneer MCACC. |

One suggestion for those having difficulty setting up DIRAC due to theater seating over two rows, you may want to think outside the box a little. As you are essentially dealing with a very large couch, you sweet spot is probably dead center in between the two rows. From there, you can then move laterally and up and down as you take the other eight measurements. This should give you a more balanced sound across the two rows. If this is not adequate, then Emotiva needs to allow us to download the full version of DIRAC (if they haven't already) so that you can choose from things like stadium seating and Freq. and time alignment per speaker pairs, etc.
That being said, your sound will be flatter than before as mine was after I did my first set of room correction filters with REW. I then had to spend some "quality time" adjusting the filters to produce a nice blended sound. I also took the sub out of the equation as mine can do phase, line, and 25Hz level control; and set my speakers to full range. All that being said, it seems more and more that the solution for most people will be the full version of DIRAC or working with REW to produce that quality of sound that they are after.
My only question now is the fact that the DIRAC license cannot be transferred to a new owner and that they need to purchase one from Emotiva. Does anyone know how much this will cost? Something to consider if you ever want to sell your unit.

I put the mic between rows 1 and 2 and split the difference between ear heights for my #1/primary reading. I toggled between the rear side of row 1 and the center of 2 to get a good room depth sample. The 3rd row I left out as it is high back stools behind the bar that seldom get used unless we do neighborhood movie nights with a full house. Scott |

Another interesting tidbit that I found in the MiniDSP dirac manual that I have not tried yet.
I cant do much testing this week. If someone want to give this a shot, that would be awesome.

Tony If by "give it a shot", you mean check that Dirac does another sweep through the left front speaker at the end, I can tell you that it did when I ran Dirac. This was mentioned somewhere in the Forum in one of the many Dirac discussions. Where, I don't remember, but the explanation was that this is done as a check that no changes occur in the midst of the measurement session. |

Nada, forgot that you can't see bold or color changes in forum apps. It was the part that states that you can point the mic towards the ceiling or floor. I have run no tests with the mic pointing down. Tony |

The third sweep is important because it is used to be able to compensate for the clock drift between the input device (the USB mic) and the output device. Not relevant for frequency response but for impulse response. Flavio |

I find it pretty awesome that you quoted one of my answers back to me. It's good to know that all this time being spent answering questions is actually being read.  my sincerist thank you, Tony |

Flavio Uh, do mean this is checking if, over the course of running the sweeps through all connected speakers, the clocks in the XMC-1 and the mic/preamp have drifted further apart than they may have been at the start? |

Unknowingly I run Dirac with mic set at zero volume in the mic's property page.
The volume turned out to be exactly the same as my preset and the sub is as loud as my preset with tight output.
The only drawback is my center is kind of shrilling a bit.
I have to run it again with 100% mic volume.

What confuses me the most is the requirement for line of sight for all speakers. I understand why line of sight would be important, but how attainable is it for most surround setups? As I understand after the first mic position at the main listening point (location and height), how would someone go about making sure a mic position that is lower and in front of the main mic position have line of sight of the rear speakers? Here is a pic of my room. If I were to place the mic 8-10 inches below the main listening positions height and slightly in front of the main listening position's location, I would think I would lose line of sight for both rear speakers.  I would think the same situation would happen if I were to do anything behind the main listening position and below, I would lose line of sight to the front three and possible side surround speakers. Am I missing the simple answer to this problem? Edit: Sorry, I was slow to reply and it appears a similar questions was asked. But I still worry about line of sight for anything lower than the main listening position's height. Dewan, line of site seems for me to be crucial for best sound, you could lay the the chairs on their back to get an overall lower profile, allowing better line of site. |
