The Auzen X-FI™ Prelude 7.1 sound card marks the first time Creative has permitted a third-party sound card vendor to use the Creative X-FI™ chipset in its own sound card design. The Auzen X-Fi Prelude 7.1 sound card fully supports EAX 5.0 and has expandability similar to that of the Auzen X-Meridian™ 7.1. Additional features such as Dolby® Digital Live, DTS® Interactive, and DTS NeoPC™ are available via driver updates.
