Dolby Pro Logic II encoding allows five channels of audio to be encoded into an Lt/Rt signal.
A Pro Logic II decoder relies on amplitude and phase differences between the two channels of an Lt/Rt signal to extract five channels: Left, Right, Center, Left Surround, and Right Surround. All five channels of Dolby Pro Logic II are full bandwidth.
The advanced steering algorithm in Pro Logic II allows it to gracefully decode any two channel source material, ranging from stereo music to Dolby Surround content, as well as Dolby Pro Logic II content.
Content encoded with Pro Logic II is backwards compatible with Pro Logic decoding, as well as stereo playback.
