Motion Picture Herald (Oct-Dec 1932)

November 19, 1932 Motion Picture Herald 43 means for connection of the receivers to the main sound system of a theatre so that persons who are hard of hearing may hear the sounds of the picture as well as a normal person. These systems for the hardof-hearing have made the talking picture as much of a source of entertainment to the person with impaired hearing as the silent picture was before, and through the device, the partially deaf person has been retained as a patron of the motion picture theatre.

At their command are factors which make or break the show. With enormous switchboards to control, emergency lighting plants, motors, generators, arcs, dimmers, transverters, magnetic appliances and many other involved and sensitive electrical instruments, it devolves on the theatre to provide adequate equipment for their correct operation. In the list of necessary measuring instruments are ammeters, voltmeters , vacuum tube testers and the like. All these and others tend toward improving lighting.

Electric Pickups electric pickups take the sound vibrations from records, transmit them to the amplifiers. The stylus (or needle) runs in a groove on the record and is caused to vibrate according to the groove made at the recording. On the phonograph this needle vibrates a diaphragm located in the neck of the horn, and these vibrations are amplified to audibility by the construction of the horn. Electric pickups are used to convert the mechanical energy picked up from the record by the stylus, which also is the armature of the reproducing unit. A fluctuating audiofrequency voltage is generated in the coil surrounding this armature, which is amplified either through the audio-amplifier (of the radio set) or through the amplifier of a public address or sound picture system.
