What is Dolby Pro Logic Audio?
Dolby Pro Logic is an established 5:1 channel surround sound playback system which includes all 6 channels of surround sound information in 2 stereo channels. A normal stereo amplifier can play a Pro Logic recording as stereo, but a Pro Logic amplifier can decode the “hidden” Pro Logic information to send all 6 channels to the speakers. Pro Logic has been around for a few years, and is available from virtually all audio manufacturers.
