      If the DDRC-24 doesn’t appear in the Sound System tab for your miniDSP Recording Equipment, re-read the installation instructions and confirm that you have executed the 'copy.bat' (Windows) or 'copy.command' (Mac) batch/command file. Make sure that you quit DLCT before doing it. Check that the USB cable to the DDRC-24 is firmly connected and that you do not have any other program running that is attempting to communicate with the DDRC-24, such as the DDRC-24 plugin. Ensure that you have the miniDSP version of the software installed, called Dirac Live Calibration Tool For miniDSP. Finally, go to the Sound System tab and click the Rescan button.

    Why doesn't the Dirac activation screen recognize the serial number for miniDSP DDRC-24?

      Carmen AndersonSep 14, 2025
      If the Dirac activation screen does not recognize the serial number for your miniDSP Recording Equipment, do not use the serial number printed on the label of the unit. You must use the serial number obtained from the firmware using the DDRC-24 plugin program.

    Why doesn’t the license validation screen accept my username and password for miniDSP DDRC-24 Recording Equipment?
    • S
      Stephen OrtizSep 16, 2025
      If the license validation screen doesn’t accept your username and password for your miniDSP Recording Equipment, the 'username' must be the email address that you used when activating your license on the Dirac Live activation screen. Check that you are using the same email address and password.
