Hello,

I have a DDRC-24 and am trying to run the Dirac 2.0 calibration software. After selecting the device, I'm not able to correctly set the audio level calibration.

The left (or Dirac 1) input generates noise and I'm able to set the correct level with the mic signal showing up next to the fader.

However, when trying to set the right (Dirac 2), I can hear the noise out of the correct speaker, but there's no input signal from the microphone.

Anyone know what I'm doing wrong?

This is the Mojave security & privacy settings for the microphone blocking the UMK. Quit Dirac V2 and launch it again before restarting the DDRC, it will request access to the microphone and the levels will appear on the volume calibration meters.

Thanks for the response. I had to go into system preferences, to the security settings and toggle microphone off and on. Everything's been working as it should.

RESOLVED: George at Deercreek Audio sent three suggestions.  I had used a new, very long USB cable for convenience on this.  He cautioned that USB cable length might be the culprit.  Switched to shorter cable and it worked.

Charlie, I'm having the same problem with latest Mac--

I've run Dirac before, but running again today (new furniture) and it won't work.  I open the SHD app, launch latest version Dirac. It sees the UMIK mic.  Here' where the trouble starts:  When I run mic volume calibration the left channel (Dirac 1) performs normally and shows a mic volume (about -25dB); when I play the Dirac 2 test tone I get pink noise with the same loudness but the mic volume indicator bar does not appear, as if it is hearing nothing.  Fast forward to doing the first calibration- I get good sweep tones from both speakers but upon completion the app says Low Signal-to-noise level error.  This is not the actual case (no noises or hum in room).  I think it's annoyed that it doesn't "hear" Dirac 2 on the sweep, same as on the calibration.  Since it's a mono mic and working fine, I can't think of how to get it to "hear" both.  Tried restarts/reboots... 

Next day- tried again running latest SHD and Dirac on a Mac Air latest model.  Same problem: mic calibration only responding to Dirac 1, not Dirac 2.  I tried it using the Mac Air's built in mic and both channels respond.  (But of course I need to use the calibrated UMIK to do the actual work).  

I am having exactly the same problem: it started after the introduction of miniDSP console and a Dirac update. I see another couple of identical reports on the Internet bit none actually gives a solution. Has someone else had this issue and rsolved it ? It’s driving me crazy
