The international photographer (Jan-Dec 1934)

December, 1934 /' h e I N T E R N A T I 0 N MOTION PICTURE ( C 'o n tin U I'd bers it properly ; sets the footage counters on the recording machine at zero ; and then writes down on a special form card all the details, such as picture name of the number, director of the picture, film roll number, and film recording machine number. Then he turns on the current to the various film recording circuits and adjusts the rheostats to the positions that provide the proper meter readings. When the director and cast on the stage are ready to make the take, the microphone man calls the recorder operator on the intercommunicating telephone, gives him the scene number, and calls for "interlock." The recording engineer then closes the first of the two motor switches mounted on the wall near the recording machine and turns on the recording room signal light. This motor switch interlocks the rotors and stators of all the motors in use — those on the cameras as well as the motors on the recording machines — and brings them all to the starting position. The microphone man calls out, "Interlock !" when he sees the recording room light go on ; and when everything is quiet and ready on the stage, he turns on his stage signal light and warns: "We're running." At sight of the stage signal light, the recorder operator closes the second motor switch, which sets all of the interlocked motors into rotation. He adjusts the motor rheostat (mounted in the large metal box on the wall of the recording room) that compensates for changes in the amount of motor load on the master Selsyn motor in the generator room. He watches the extension milliammeter in the motor control circuit (mounted on the wall just above the motor rheostat) until it shows a reading that indicates that the motors are up to their normal speed of 1200 revolutions per minute. Then he snaps on the switch that lights the room. At this, the microphone man calls out "Speed !" The scene is "shot," the actors going through their rehearsed parts ; and when it is finished, the microphone man switches off the stage signal light. When the stage light P H O T O G RAI'H K \i Twenty-five SOUND RECORDING from Page 7) bull's-eye running lights on the stage and in the recording blinks off in the recording room, the recorder operator turns off the motors by opening the two motor switches.

One strip shows a normal sound record; the other is the record of an audio frequency tone, such as produced by the oscillator on a light valve tuning panel. He then writes down the scene number, whether or not it was satisfactory (which he learns by telephone from the microphone man), and the number of feet of film run through the recording machine. Then he makes the necessary preparations for the next take. This concludes the series of four chapters describing the Western Electric system of recording sound on motion picture film.
