WITH 1000 WATT PROJECTION LAMP AN D 25 WATT AMPLIFIER.
Model 130, with provision for two projectors with instantaneous single-control change-over, is the ideal 16 mm. equipment for semipermanent installation in a large auditorium. It permits fully professional presentations of sound film subjects of any nimiber of reels. Filmosoimd 130 employs either one or two looo-watt Filmo Auditorium Projectors. The illuminating power exceeds that of any other 16 mm. projector. i6oo-ft. film capacity allows 45 minutes show. It may be operated at either 24 or 16 frames per second (for sound and silent films). Film take-up is by a separate motor, which also provides power for rapid film rewinding.
The projector is fined with fast 2-inch F 1.65 lens instantly interchangeable with special lenses. After passing through the mechanism film is cooled and re-humidified. There is a ndio interference eliminator, pilot light, snubber to cushion film against take-up tension, two-way tilt, and variable limp resistance and voltmeter. The sound head is similar to that of Filmosound Model 120.
