Digital film print, a stereo analog optical print (A-type or SR), or a mono
analog optical print should be identified as such on both the film can and leader.
However, with handling, the identification may be lost. If you are not sure if you have
a stereo analog print, play a reel and find a section with music or effects only. (On
dialogue or narration, stereo soundtracks look much the same as mono soundtracks.)
Examine the soundtracks closely.
On music and effects, the two soundtracks will appear to be different on a stereo
print. On a mono print they are identical. If you received the wrong print, be sure to
check with your local exchange or the film distributor.
