So -- a light analysis is complete -- Either my cal for the cross spectrum mic is off or the emotiva cal file is off between 6k and 14k. were not talking about much though. I am seeing that that with the cal file that tunatamer found, at its worst - the emo mic is 5db (imagine a hump that goes from 0 to 5 to 0 over the span of 8000hz) lower then the cross spectrum mic. Now this is my microphone, I am not sure what others will have. Need some more volunteers with REW and the XMC. Tony I am up for it. I am now wondering if I use the EMM Cal file in REW and then adjust the txt file, so that it matches my Calibrated mic better, then put it back on my PC. Would Dirac then use my corrected txt file or regenerate one? |

Wondering if Dirac would then use my correct txt file? Not sure, let's find out if the results are about the same first. If there is enough data to suggest that the cal is off. Then we could get emotiva to change it. But altering anything about how dirac operates without permission would likely violate the license agreement. Tony |

Awesome news audiophill!!! I'm happy for you. It seems one down....and Deewan to go.....Deewan, without wading through.....do you have a new cable and/or mic to try yet? Well, my first cable to a complete dud. My second (current) cable is defective. So it sounds like I may need to call Emotiva and request another cable. I'll call now. *fingers crossed* Hmmm......My gut tells me there is a driver conflict in the computer rather than bad gear. We test the pics them selves three time over while they are being assembled. The cables are tested at the manufacturer so i can believe a bad one will pop up here and there, but two in a row? If you are yelling into the mic, I feel pretty confident the element is blown which is not a problem, we will replace it. When you get the new mic lets see what happens. Lonnie |

Test with REW both Mic's using there cal files. Stereo mode, Speaker preset 2. Just remember my EMM mic could be out too, more than others. Left Speaker - Umik (RED) and Emotiva EMM (Gold)  Right Speaker - Umik (GREEN) and Emotiva EMM (BLUE)  |

Tony Digging a little more -- the mic seems to be 6db lower then the calibrated microphone at 200 and below. Tony |

Left Speaker - Umik (RED) and Emotiva EMM (Gold) View AttachmentRight Speaker - Umik (GREEN) and Emotiva EMM (BLUE) View AttachmentYour seeing the same things I am. About 6db off in the high end and in the low end. Dirac would compensate by decreasing bass by 6db and increasing highs by 6db.... But, your extended all the way to 20. Did you use the 90 cal file for your UMIK? was yours UMIK batch calibrated or single calibrated? Tony |

Yes I used the 90 cal file. Had both mic's pointing to the ceiling. Report attached in PDF. used the "narrow_band_response_90_degree.frd" 700-5164_mic_report.pdf (409.37 KB) Using the Emotiva cal file from my Dirac installed PC with the EMM mic "EmotivaMicCalOA.txt" |

If so then that sag is pretty brutal. I remember reading keith said it would only be 3db variation at most and the effects would be negligible. I am tempted to send my mic to Cross Spectrum and have it calibrated if this is the case. Richard. |

In filter application this would turn to a lower low end and higher highs after calibration. That seems to be what I am hearing with Dirac engaged. Looks like my EMM mic might be ok then, just how Dirac is configured. If more mic's test the same, maybe Emotiva could update Dirac to compensate if it is not done already? |

ansat, yours is better from around 14K and up than mine though.

I take it we can then set the areas that Dirac will have an effect on? |

Lonnie My first cable was defective and the cable was not recognized by any of the three computers I hooked it up to. The red LED light would never shine. The second cable the LED light shines and blinks, but the mic doesn't hear anything. I ended up getting a call from Damon and he said he spoke to another customer who had the same situation and a new cable fixed his issue. He is shipping me a new cable, said it should go out on Monday. I guess my hope would have been to get a mic/cable combo that has be tested before shipment to ensure both are working. I'd be more than happy to ship the two cables and mic I currently have back to Emotiva on my dime if I could get a new set that was confirmed working. |

Actually would be great if Emotiva would modify Dirac to allow us to be able to use a aftermarket Calibrated mic plus its cal file.
Would love that!

well -- made a new cal file for rew. I am waiting on another to verify it is more accurate. I am showing within 3 db total for 18hz-20k  |

My guess is Emotiva is under estimating the talents we have in the members here and the lengths some will go to to get the best from thier systems.
I have yet to get dirac run but also have a calibrated Dayton mic and file but not sure if the Emotiva cable will provide enough phantom power to operate that mic. My guess is the dirac software wants to see that usb cable interface either way so mic options might be locked in too. For REW that's likely to be less restrictive.
