Description
 
The stereo cassette deck which realized a 20kHz property difficult also on the premium-grade 3 head deck with two heads.

The sender strike lamination core which examined and sorted out many properties is adopted as a reproduce head.
The merit of a material is efficiently employed by the original process which does not give stress to a core.
Moreover, the erase head has adopted the double gap type which used the Low-Mass ferrite core.

The silence mechanism of a microprocessor control is carried.
The precision type motor operated the head assembly, the pinch roller, and the reel brake, and has prevented the deviation of the head alignment positioned precisely.
Moreover, fail-safe which gives a damage to neither a tapes nor a mechanism is also given to the rapid transition of operation by the motion control by a microprocessor.

The amplifier circuitry consists of dual mono-constructions in order to prevent a cross interferencee.
A total of 12 regulation circuits are established in sound-recording amplifier, and the capacity of the tapes is pulled out.

The power-source part adopted the multi-regurated power supply scheme, and has eliminated the noise interference between circuitries.

The Dolbey B/C type noise reduction is carried.

Functionalities, such as a bias fine-tune volume, a MPX filter with a defeet, an auto-repeat, timer sound-recording / play organization, and an REC Mute, are carried.
