Turtle Beach AUDIO ADVANTAGE MICRO USB 5.1 Surround-Sound Card

Easy replacement for any sound card on any computer with a USB port. On computers with older sound cards, you can have a richer and fuller sound experience with it's built in amplifier.
Dolby Pro Logic, Dolby Headphone and 5.1 Virtual Xear multi-speaker simulators for creating 3D surround effects. Audio out options include the ability to plug in a headphone, speakers, or an optical cable using the included SPIDF adapter.
Wide variety of digital ambiance settings for simulating many different effects. Listen to DVD audio with spectacular simulated home-theater surround-sound on stereo headphones.
Multi-band equalizer with user-defined presets for adjusting tone, included on the Audio Advantage Micro CD that ships with the unit.
Powered by the USB bus - no external power needed! About the size of a pack of gum. Works with all standard stereo headphones with a 3.5mm mini-jack,

Includes USB stick, optical digital adapter jack, installation CD and USB extender cable. Item is new, unopened in original packaging. Released in 2004 for Win98SE, ME, 2000 or XP. I will include a CD with Turtle Beach drivers (zip files) for 32 and 64 bit Windows systems up to and including Windows 7. Device compatibility for later OS is not guaranteed. Final caveat: the AA has a powerful amplifier. Reduce the power as low as it will go (or better yet, adjust each channel of the software equalizer to its lowest setting) before plugging in headphones.
