Siemens Dual-Strip 16/16 Projector with Synchronous Motor
Heinz Kronenberger · Journal of the SMPTE · 1958
Dual-strip 35mm projectors carrying picture and sound on separate films have been in use for years in editing and production work. Siemens & Halske has had for some time a 16/8 dual-strip projector, consisting of their Model 2000 Projector with an additional film transport system for 8mm magnetic sound film. This is used chiefly by schools and industrial film makers for adding sound to silent films, as well as for supplying vernacular narration for foreign-language films.
