Notes: 
1.  The serial number that must be entered in the activation screen is not the serial number printed on the 
hardware unit. A unique serial number specific to Dirac Live is programmed into the firmware of each unit 
and can only be accessed with the nanoAVR DL Utility program (step 4 above). 
2.  The email address used during license activation is not related to your user account on miniDSP.com. To 
activate and validate a Dirac Live license, you must create a separate account on the Dirac server using the 
form shown at left in step 5 above. 
3.  If you purchase more than one nanoAVR DL or Dirac Series processor, each will need to be activated with 
its unique serial number. Use the form shown on the right in step 5 above and enter the serial number of 
each additional processor, and they will in turn be added to your license. 
2.1.4  License validation 
Quit the NanoAVR DL Utility program and start the Dirac Live Calibration Tool For miniDSP program. It will ask 
you to validate your software license. Enter the email address and password that you used when activating your 
license, and then click on Validate:  
You will need to be connected to the Internet to validate your license. Any active firewalls will need to have 
HTTP (normal web traffic) enabled. 
The Username in the validation screen must be the email address that you used in the activation screen 
in step 5 on page 12. It is not your miniDSP website username.
