Commentary
Stereo cassette deck for metal tape.
The newly developed Sendust head is used as the recording and reproducing head, making it compatible with metal tapes.
In addition, it is equipped with a 4-position tape selector with metal position.
The ST mechanism (soft touch operation) is adopted for the tape control button to realize the soft operability.
This ST mechanism operates the head housing the head housing using the driving force of the motor. There is no mechanical load on the play button. It is also equipped with a one touch recording function that allows you to record with just one press of the record button.
A 15-point peak level indicator is used as a level meter.
The entire circuit is integrated into an IC Dolby circuit, which improves the characteristics.
