A duplicator consists of 3 major components: a source drive, target drive(s), and a duplication controller card. The controller card is the heart and brain of the drive that controls the data flow between the source and the target(s).
Disc duplicators do NOT burn any copy protected material AT ALL.
USB CONNECTION ADD-ON:
With this external interface connection, one of the burners on the duplicator can be used as an external optical drive from your computer.
Using your computer, you can then create a master disc from the duplicator. We highly recommend this option for users who do not have an optical burner on their computer.
HARD DRIVE ADD-ON:
A hard drive (HDD) can be added and built-in for storage and better performance. A hard drive will increase the burning speed and stability of duplication.
If you have multiply originals which need to be duplicated time after time, the built-in HDD add-on is definitely recommended.
Hard drive add-on is not available for 1 burner duplicator.
