Ultimate Surround Sound Experience
Music, movies and games all become more intense, more alive when you're surrounded by sound. Revolution 7.1 is the ultimate PCI solution providing output for up to seven speakers and a subwoofer, rivaling even the best movie theaters. Where 5.1 places speakers beside you, 7.1 places them both beside and behind you for a much more immersive and believable surround sound experience. Sound effects become so real that you'll find yourself ducking to avoid bullets and low-flying planes. And Revolution 7.1 fully supports stereo, 4.1, 5.1, and 6.1 formats as well.

Listen to all your music in surround
Built-in SRS Circle Surround II technology instantly transforms your music collection into incredibly lifelike surround sound music. It dynamically separates instruments, vocals, and even crowd noises for an experience you have to hear to believe. Full support for Microsoft Windows Media 9 means you can play surround sound audio from the Internet today. And if you don't have a 5.1 or 7.1 speaker system, TruSurround XT lets you enjoy the benefits of multi-channel by providing virtual surround sound on your stereo or even headphones.

The gaming advantage
Ultra-realistic 3D positional audio makes you feel like you're really in the game and gives you the advantage of hearing exactly where danger lies. Revolution 7.1 supports today's popular game technologies such as Sensaura, EAX, DirectSound, and A3D. Your games will never be the same.

Advanced technology made easy
One name is found in more studios and used by more music professionals than any other: M-Audio. Now we've distilled over a decade of pro audio experience into the highest-quality, easiest-to-use PCI-based surround sound solution. You get incredible specs like 107dB signal-to-noise ratio and 0.003%THD for pristine audio fidelity.
