Description
 
Three head schemes, the stereo cassette deck which adopted DD2 motor.

The S&S pair head which uses a sender strike, respectively is carried in the head only for a play only for a sound recording.

Two motor stream compositions which used the FG servo DD motor for capstans, and use a DC motor for reels are adopted.
The important capstan part was direct driven by FG servo DC motor of a large-sized fly wheel and coaxial solid construction, and the stable run performance is realized.

In order to obtain a back tension proper from the start of a tapes to the end, the electronic servo back-tension system is adopted.
By detecting the rotational frequency of a supply side reel electrically, and controlling it, the stability of a tapes run improves and level fluctuation, a modulation noise, etc. are reduced.

Super servo amplifier is adopted as an output stage.

The fadeout functionality is carried.
Fadeout time can be adjusted freely manually and a fade-in operation is also possible for it.

The accu-bias scheme is carried and the performance of a tapes can be pulled out.

Peak level meter is carried.

The REC-Mute functionality is carried.

A timer standby organization and Dolby noise reduction are carried.
