Commentary
A thin stereo cassette deck with a Sendust head.
A hyperbolic type Sendust head has been adopted for the recording / reproducing head.
This head uses SENDUST, which has excellent wear resistance and high-frequency characteristics, for the core and dummy core to improve the head touch and characteristics.
The drive system employs a PLL-based high-torque DC servo motor that controls the rotational accuracy of the motor with a phase difference based on the reference signal of a highly accurate oscillator, thereby achieving stable tape travel.
A slot-in system is used for the cassette mounting part.
Equipped with a needle-type tape gauge, you can display the remaining amount of C-45, C-60 and C-90 tapes by time.
Equipped with a tape selector with an automatic tape switching mechanism for CrO2 position.
By simply setting the tape for the CrO2 position, the appropriate bias / equalizer is automatically selected.
