  PRELIMINARY AND SUBJECT TO CHANGE  
miniDSP Ltd, Hong Kong / www.minidsp.com / Features and specifications subject to change without prior notice  13 
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 DDRC-88A Utility program (step 3 above). 
2.  The email address and username used during license activation and validation are not related to your user 
account on miniDSP.com. To activate and validate a Dirac Live license, you must create an account on the 
Dirac server using the form shown at left in step 4 above. 
3.  If you purchase more than one DDRC-88A or Dirac Series processor, each will need to be activated with its 
unique serial number. Use the form shown on the right in step 4 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 
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 
above. It is not your miniDSP website username.
