The only duplicator that produces copy-protected discs without a computer, EZ Dupe’s Disk-Lok duplicators will provide peace of mind. This exclusive technology automatically embeds copy protection within each target disc, preventing them being copied on a computer or another duplicator. Perfect for musicians, artists, photographers, cinematographers, writers, and other creative fields. Permits multiple copies to distribute and showcase work, yet never have to worry about work product being reproduced after the disc leaves your hand. These protected discs will play normally on DVD players or drives. The EDL5 will produce up to two simultaneous DVD or CD copies.
