As the subject says, I cannot get Dirac to work on my NAD C658. Crutchfield's help desk is useless and NAD's is unresponsive.
Whenever I try to run it on my laptop I get a message that says "low signal-to-noise level" and says turn off HVAC, etc. The room is DEAD QUIET and I've tried every combination of microphone gain and speaker level to correct this.
As evidence that it's not the room's fault or room noise, when I run Dirac either my Ipad or Iphone, I am able to successfully get through all of the measuring points. But when it processes the measurements, I get a message that says "Invalid argument. Restarting the application may be necessary." It happens every time.
Any ideas/help you can offer would be appreciated. It's getting to the point where I'm so frustrated I'm getting ready to send the NAD back to Crutchfield.
