Dolby Surround Sound existed in home receivers before Dolby Pro Logic. Pro
Logic was an improvement over "plain" Dolby Surround. It added steering logic
to help direct the sounds to the proper speakers.
Now Dolby Digital is a discrete set up while Dolby Surround and it's enhanced
version, Pro Logic were matrixed kind of similar to SQ quadraphonic sound.
The big improvement in Pro logic was the steering of the center channel. But
like SQ you still only have 4 channels because the right and left rear carry the
exact same information.
