M-AUDIO 9900-40901-00 7.1 Channels 24-bit 192KHz PCI Interface High-Definition Surround Sound Card

Step up from your motherboard's integrated audio solution and surround yourself with sound with the Revolution 7.1 from M-Audio, one of the leaders in professional computer audio solutions. The easy-to-install PCI card works with Windows and Mac desktops. Eight analog outputs provide full high-definition 24-bit/192kHz audio playback on up to eight channels transmitting analog audio as a digital signal (PCM). A coaxial digital out adds pass-through of Dolby Digital EX and DTS ES decoding using third-party applications.

There's also support for SRS TruSurround XT that simulates surround sound through stereo speakers and SRS Circle Surround II, which takes stereo content and makes it into surround. Game support includes APIs for Sensaura, EAX, DirectSound and A3D and there's a software-based control panel for bass management and other audio tweaking features.

A line-in jack allows for recording from music equipment, CD players and digital audio players directly to your PC and an external mic input is onboard, too, for connecting a microphone for recording sound or for video conferencing, gaming or Internet phone calls or chat.
