Dolby® Pro Logic® II technology processes any high quality stereo (two-channel) movie and music audio
into five playback channels of full-bandwidth surround sound. A matrix surround decoding technology,
Dolby Pro Logic II detects the directional cues that occur naturally in stereo content and uses these
elements to create a five-channel surround sound playback experience. It's ideally suited for home
theater systems, PCs, game consoles, and multichannel in-car audio systems (as Dolby Pro Logic II
Surround).

| Figure 1 How Dolby Pro Logic II Works |
Dolby Pro Logic II is fully compatible with all Dolby Pro Logic technologies. It provides optimal audio
for playback in a 5.1-channel home theater system for the thousands of videocassettes and TV programs
encoded in four-channel Dolby Surround (the encoding counterpart to Dolby Pro Logic's decoding
technology. Dolby Pro Logic II also enables video game consoles to encode five-channel surround sound
information into a stereo signal with virtually no impact on the console's CPU, which means all this
extra audio won't slow your game down.
Dolby Pro Logic II can bring new life to your CD collection. Play your music through your home theater
system, and you'll hear seamless, natural sound with new depth and detail – it's almost like hearing
a newly remastered CD.
In addition to enhancing playback, Dolby Pro Logic II can be used to encode TV programming to deliver
a surround sound experience for viewers with stereo TV systems.
