Commentary
Stereo cassette deck in pursuit of operability.
With an emphasis on the sense of operation, large self-illuminated operation buttons are concentrated in the center of the front panel. The LED lights on each button with a light touch and the driving mode can be confirmed by light.
A dedicated electronic servo motor is used to drive the head base to achieve an extremely quiet vertical motion while reducing damage to the head. The ejection is also a motor drive system that uses the rotational power of this motor to drive the head base.
It is equipped with functions such as a PMS function that allows you to repeat one song (music repeat) or find the beginning of the song you want to listen to, and an auto rewind / memory play function linked to the counter.
It is also equipped with REC mute and timer standby mechanism.
Equipped with the Dolby HX System, which is compatible with a wide range of music sources and greatly improves the high-frequency characteristics of Chikara Dainyu.
Uses Sendust head for the head.
The drive train uses a DC servo motor for the capstan and a DC torque motor for the reel.
