Premier 16 mm 1950 - Synchronizer 4-band synchronizer for 16mm film, with counter.
The first step consisted in fixing the tape on the reels and then, after this adjustment, the tape was passed through each of the synchronizer bands, whose surface was toothed to hold the tape. The counter made it possible to mark the sound and image tape, making it possible to synchronise the magnetic sound (klang) with the film.
Each band had a locking mechanism to enable editing / synchronization separately from the other band(s).
