Commentary
The world's first chrome cassette deck that meets DIN standards.
It automatically sets the bias and equalization according to the tape used.
The dynamic noise limiter circuit effectively eliminates tape hiss.
It uses a servocontrol system with a tacho motor to improve the stability of tape running.
Electromagnetic coupling is adopted in part of the rotation transmission mechanism to realize smooth and uniform tape winding torque maintenance.
Equipped with an auto-mechanical release mechanism, the pinch roller separates from the capstan at the end of the tape.
Uses an auto 0 stop mechanism that works for both constant speed tape travel, fast forward, and rewind.
The recording amplifier and the playback amplifier are individually designed.
Mixing of line microphones is possible.
It meets the German Industrial Standard (DIN) HiFi specification 45500.
