Commentary
Stereo cassette deck with 3-head system and DD2 motor.
Equipped with an S & S Combhead that uses Sendust for both recording and playback heads.
Uses a 2-motor configuration that uses an FG servo DD motor for the capstan and a DC motor for the reel.
The important capstan section is directly driven by an FG servo DC motor that is coaxial with a large flywheel to achieve stable running performance.
An electronic servo back tension system is used to obtain the proper back tension from the beginning to the end of the tape.
By electrically detecting and controlling the rotation speed of the supply side reel, the stability of tape running is improved and level fluctuation and modulation noise are reduced.
A super servo amplifier is used for the output stage.
Equipped with fade-out function.
The fade-out time can be freely adjusted manually, and the fade-in operation is also possible.
It is equipped with the accu-bias system, so you can draw out the performance of the tape.
Equipped with a peak level meter.
Equipped with Rec Mute function.
Equipped with timer standby mechanism and Dolby noise reduction.
