Almost everyone has experienced the enveloping, electrifying effect of 5.1-channel surround sound in the cinema and at home. Surround sound is addictive. Once you get used to it, you'll never want to go back to plain stereo sound. And now you don't have to.
Pro Logic II from Dolby Laboratories gives you multichannel surround sound from any stereo source?CDs, tapes, videocassettes, TV broadcasts, AAC files, you name it. No matter if you're listening to Stravinsky, the Stones, or a Schwarzenegger movie, you'll get the realistic, involving sound you'd expect from a 5.1-channel system.
How Pro Logic II Works
Pro Logic II is a dramatically improved, updated matrix surround system, based on the principles used to develop the original Dolby Pro Logic decoding back in the 1980s. The original Pro Logic features four channels?front left, center, and front right, plus a mono surround channel that's usually split between two rear speakers. The surround channel is also "band-limited," reducing the treble frequencies. Pro Logic II further enhances the sound with a full-range stereo surround output and a greatly improved steering logic, resulting in high channel separation and an exceptionally stable soundfield.
