Sanyo RD-5372 cassette deck

Sanyo's new top-of-the-line cassette deck featuring microprocessor control and 3-head design.

Two motors, a servo-controlled DC motor to drive the capstan, and a second DC governor motor for the reel drive, provide high torque with extremely low wow and flutter. The integrated Sendust Alloy record and playback heads with metal tape compatibility deliver exceptional frequency response and Signal-to-Noise Ratio specifications. Outstanding electrical and mechanical performance in addition to a host of user-oriented features make the RD5372 one of the most sophisticated pieces of cassette recording equipment available

Sendust alloy Record and Playback Heads

Surpassing the capabilities of other head materials, Sendust Alloy record and playback heads are responsible for much of the exceptional performance of the RD5372 and RD5370. the single unit housing both heads provides instantaneous monitoring plus permanent alignment of record and playback heads.

MPX Filter Defeat

This defeat switch permits disengaging the 19 kHz multiplex filter for extended high frequency response when recording live or from a disc.

4-Position Tape Select

Provides optimum bias and EQ for all tape formulations: metal, CrO₂, FeCr and Normal

Integrated Record and Playback Head

Sanyo engineers had to overcome two problems to permit cassette tape monitoring: fitting three heads into the standard cassette format designed to accept only two, and maintaining exact alignment of the record and playback head gaps without the constant adjustment required of some 3-head cassette decks. Sanyo engineers met this challenge with an integrated head design incorporating separate record and playback heads into a single housing. Since both heads are permanently mounted in the same shell, they can never become misaligned, assuring the best possible high frequency performance.

Dual process Dolby Noise reduction

The Dolby noise reduction process has become accepted as the standard for reducing tape his inherent in the recording process. Two-head cassette decks utilize a single Dolby encode/decode circuit for the both record and playback. The RD5372 (and RD5370) 3-head decks contain dual Dolby circuits to encode the recording and simultaneously decode the monitor playback

Microprocessor Logic Control

The Sanyo microprocessor is a tiny digital computer, etched onto a single silicon chip. It executes programmed instructions, sensing the status of switches, controlling solenoids, and monitoring tape motion. This tiny electronic "brain" provides the logic to prevent tape damage, and controls other automatic functions in the RD 5372 (and RD5370)
