M-Audio is now shipping the Revolution 5.1 high-definition surround sound card for PCI-based Windows and Macintosh computers. Built upon the same architecture as the Revolution 7.1, Revolution 5.1 was designed with a “keen eye” toward gamers.
Gaming technologies such as EAX, OpenAL, A3D, DirectSound and Sensaura, are built in, allowing 3D audio positioning and realistic environmental simulation. Revolution 5.1 also features low CPU usage, an important factor for fast visual response in gaming. The product ships with a fully functioning version of Activision’s Wakeboard Unleashed featuring Shaun Murray—the first game optimized for surround sound on the Macintosh platform.
Three 1/8-inch stereo jacks on the unit provide six discrete outputs—five for main speakers and one for a subwoofer—for channel-accurate surround reproduction. All six of the Revolution 5.1’s outputs simultaneously deliver high-definition audio up to 192kHz at 24-bit resolution for a true audiophile listening experience. WinDVD 5 OEM is included for software decoding of Dolby Digital 5.1 and DTS. Revolution 5.1 also features a S/PDIF digital output providing Dolby Digital and DTS pass-through to home theater systems.
Revolution 5.1’s soundstage is fully configurable. The control panel allows adjustment for speaker size and distance, dialogue clarity and bass management. In addition, SRS TruSurround XT is included for recreating surround sound environments while only using two speakers or headphones. Revolution 5.1 also incorporates SRS Circle Surround II that dynamically separates instruments, vocals, and even crowd noise to deliver larger-than-life virtual surround sound from normal stereo CDs or MP3s.
The sound card also features a 24-bit/96kHz 1/8-inch stereo line input, as well as an 1/8-inch direct microphone input. Impressive specs such as a high 109dB signal-to-noise ratio and dynamic range, and a distortion (THD) rating of 0.00185 percent (-95dB).
The product operates on Windows 98SE, Me, 2000 and XP on an Intel Celeron 350MHz or AMD K6II 500MHZ with 128MB RAM, and Macintosh G4 with 256MB RAM running OS 9.2.2 or OS X 10.2.6 or later.
