Abstract
A description is presented of a complete new Western Electric double film portable recording system recently perfected by Electrical Research Products, Inc. The equipment is mounted in a trunk and is designed to be used for location, industrial, and educational recording where portability is of the utmost importance. Entirely new designs of the system amplifier, noise reduction unit, d-c. interlocking motor system, double film recorder, and other units have been perfected. The improved moving coil microphone, permanent magnet light valve, and many other recent equipment developments have been used. The minimum weight of the simplest sound recording channel of this new type is approximately 325 pounds. By adding other units, sound recording systems of any degree of elaborateness may be established.
