Abstract
A portable, magnetic film recording channel has been designed with a transistorized mixer and recorder, plus some accessories. The mixer provides for switching, equalizing and mixing of up to four microphones. Two independent VU meters indicate recording and magnetic playback levels. Optional accessories consist of microphone impedence matching transformers, precision gain controls and transistorized compressor. A high-gain transistorized playback amplifier and bias oscillator are located in the recorder. The recorder is manufactured by the “matched-plate” method in which the structural support for the primary rotational elements is provided by two match-bored magnesium panels to effect flywheel suspension between two bearings rather than by cantilever fashion.
