Product - AuzenTech X-Fi Prelude 7.1 Sound Card

The World's first soundcard custom-engineered around the X-Fi chipset.
The Auzen X-FI™ Prelude 7.1 soundcard marks the first time Creative has permitted a third-party soundcard vendor to use the Creative X-FI™ chipset in its own soundcard design. The Auzen X-Fi Prelude 7.1 soundcard 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 in the near future

• The speed you need: Powerful audio processing engine boosts real game performance by more than 15% over ordinary motherboard audio.
• Hear your enemies before they find you: Slip on your headphones or put your multichannel speakers to work for you with positional audio that's so accurate you can locate enemies by sound.
• Revitalize compressed audio: X-Fi Crystalizer technology restores the detail and vibrance to your compressed music and movies. In games, X-Fi Crystalizer makes gunshots sound crisp and sharp and explosions really boom for the most intense gaming experience yet.
