- In the August 1992 issue of Stereo Review, they provide explanation of the
- differences. It seems that Pro Logic is a more advanced method of decoding
- the "surround sound", and adds a center channel extraction and separation-
- enhancement circuits. This was taken from an article in Stereo Review. As
- for the second part I do not know. I hope someone can provide a better
- explanation. Hope this helps a little.
