Commentary
Stereo cassette deck with 2-motor and electronic control system.
The mechanism uses a 2-motor system that uses a digital FG servo motor for the capstan drive motor.
In addition, in order to maintain the high performance of the motor without difficulty, a large diameter flywheel of 80 mm φ is adopted, and in addition, a thick and highly accurate capstan is used.
A dedicated IC equivalent to 23 transistors is used for the control circuit.
The control section employs an electronic control system that uses a transistor as a switching element to eliminate relay related troubles such as poor contact, spark generated from the contact, and noise.
In addition, the operation buttons are a soft touch lock type using a slide switch to improve operability and reliability.
An HPF head is used for the read / write head, and a high-efficiency double-gap ferrite head is used for the erase head.
Equipped with a digital FL display.
It has a tape selector with independent bias and equalizer.
Equipped with a Dolby NR system as a noise reduction system.
Microphone and line mixing is possible.
Equipped with a memory rewind mechanism.
Equipped with a timer standby mechanism, and by connecting an optional timer, it is possible to record absence.
