Turn off AGC, you don't want your computer doing an automatic gain control. This will cause all kinds of level mismatches, low level indications and such. If the AGC is turned on, then the computer can be internally reducing the level of the mic to fit whatever level MS has set as its optimum. Another by product of the AGC is that when Dirac sets the levels for each speaker, you can get really weird settings, like et center or surrounds being 10 to 12db low or higher than the rest. Lonnie I have tried Dirac and the mic with both AGC turned on and off. I have tried with the mic level set to 10, 50, and 90. I can't get anything to register within Dirac from the mic. I've tried both PC laptops and just to be sure I just attempted it again. I'm running Windows 7 on both machines. Any other ideas? |

YES!!!!!!! It was the cable for me!!!!!! I can't run dirac right now as i have to leave for work. I can confirm that the mic now works with the replaced cable!!! Thank you Emotiva for all your support!!!!!!

Lonnie Lonnie, Would you please revisit this post. I totally agree that it seems logical that the AGC could be influencing DIRAC and should be turned OFF, but the default device load of the driver in Win 7 has it ON. Also if you turn it off you MUST then set the mic level in the next tab. There were no instructions about this in the DIRAC info so I'm sure that many, if not most of us who have run DIRAC probably ran it in AGC. I got wonderful results from DIRAC, but maybe I was just lucky. However, based on your speaker level comment I did just go back and check my levels with a pretty decent SPL meter and found my levels perfectly matched in DIRAC setting. So, I guess the biggest question is, should we disable AGC and re-run and if so, where should we set the mic level in the driver tab? Thanks for all you do for your customers. One other quick issue, you might recall my discussions with Keith about apparent CEC issues with my XMC connected to Pioneer Pro111 FD. This was causing my concerns with standby audio. Keith had told me that you guys were working on a CEC refinement. Any news on that? Thanks again ! This should not matter since you are giving exclusive control to applications, meaning Dirac . |

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* |

Does anyone know if there should be a phantom +48vdc voltage for the mic?
Reason for asking is if the usb interface on the pc is limiting things maybe there is not enough power to provide the phantom power required.
I haven't measured my cable to see if there is phantom power, but my Dayton room Eq mic needs phantom power to work.

Thanks to everyone on this forum for all your helpful suggestions! With the help everyone gave it made me feel better that you all cared, it helped keep my stress level down! Good luck to you other guys with this problem, but the good news is it is just the cable! I would assume the digitalizer was messed up in the old cable.

That's the measurement from mine (that works). |

Well. problem figured out now to make a call. I had a friend come over with his install of the software and brought his mic and cable. ran through the software and got everything running. After that I swapped my MIC for his and it still worked. Swapped my cable onto his mic and nothing as before. I didnt have time to try his cable on my XP machine but since my cable is dead I can bet that is the problem  at least I was able to get Dirac running and now to wait for a cable, calling now |

seems the supplier has some QC issues. Hope mine is ok,not like some of us just live round the corner from Tennessee.

I called and left and message and also emailed. Never heard back. With the weekend now, I'm afraid it will be Monday or Tuesday before I get a third cable shipped to me. Considering buying a cable online. Found a place for $9 and another place for $15. Wish I could source some locally. Might double check Guitar Center tonight. |

I gotta chime in and say that the XLR connector is one of the cheesier ones I've seen. A nice Neutrik or Amphenol connector would have been a great quality upgrade for a small uptick in cost. When I tap on the XLR I hear a rattle, probably from the button lock spring. There's no real strain relief of the preferred collet type, just a stamped steel clamp over the cable. If anyone at Emo is interested I can hook ya'll up with my US reps. I've had wonderfully manufactured proprietary designs of all types of connectors made for me by both companies. Small detail but just sayin'  |

I called, was on hold, they came back online and asked if I wanted them to call me back, sure..... the lady on the phone asked what the issue was and said said she would see if they could just send out a cable, didnt think she needed to have me talk to a tech to authorize that, but said would have someone call me back. she said it wasnt the first call on a cable...... no call as of yet. another thing, tried to use my USB mic pre and calibrated mic I have for measuring sub kits before I send them out and its a no go, software wont recognize it I dont know if its been covered some place else but are the mics just so tightly calibrated that they dont have/need a cal file or  ? how tight of a tolerance is on them?

Tuna.... I love you. Just sayin. I'll have some goodies in a bit. But right now, dirac is correcting 20k at -7. I only measured my mic at -4 |

So you are saying that every MIC is exactly the same? I have never seen anything manufactured be exactly the same every time.

But we have a lot of users stating that they feel that Dirac is doing too much to the highs. So I am wondering if the something is off in the cal file. Which Tunatamer was so kind as to point me to. (BTW - in win 8 its not in c:/dirac. You have to really dig for it.) Tony |

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 |
