A Portable Sprocket-Type Magnetic Tape or Film Recording System
Three professional magnetic recording systems have been designed, employing sprocket-hole 1/4-in. tape or 16mm or 17 1/2mm films, to meet the operating and quality requirements of the motion-picture industry. One of two small carrying cases contains a two-position mixer, including preamplifiers, recording amplifier and the 115-v a-c system power supply. The recorder includes a bias oscillator and monitor amplifier, both transistorized. The recorder operates synchronously from an a-c line or from power derived from the camera motor.
