What is the difference between the 5.1 1980 mix and the 2.0 1980 mix? Are there any content differences, or are they just mixed through more channels?
Also, does the 16mm mono track differ from those two in any way?
And unlike Jedi, we know that there are content differences from the six-channel mix, but the six-channel mix didn’t apply to this cut of the film.
Which cut of the film does the six-channel mix apply to? And where can I find a list of differences between the original stereo and the six-channel mix?
The six-channel mix goes with the 70mm cut of the film. The 35mm cut only had stereo (and mono in the 16mm reductions). I’m not sure there’s a complete catalog of audio changes, but if you search for differences between the 70mm version of Empire and the 35mm version of Empire, some audio differences are included in the mix. You can also watch Puggo’s 8mm digest to see and hear many of them.
