[Dan Dugan]

I believe the standard track order for Quad is L, R, Ls, Rs, but I can’t quote an authority for it.

My few 1970s recordings in quad were 1,2 and 3,4 for front/rear--I think--though the one quarter track one I did was perhaps LR LF RF RR to keep the front channels away from the edges--I haven't seen that tape for years, but I may still have it. I was fairly good with metadata from the start.
