Commentary
Reverse tape deck with direct drive system and AC servo motor.
The capstan uses a direct drive system that uses an AC servo motor to reduce wow and flutter.
By using a combination head for erasing and recording, we have realized a six head configuration with four heads in appearance, making it possible to reproduce three Headley birth records.
In addition to the center capstan system, we have adopted an auto-positioning pinch roller that moves to the optimum position depending on the direction of tape travel.
Equipped with a tape selector switch capable of using low-noise tape (SLH).
Mic/Aux mixing is possible.
Equipped with an auto shut-off mechanism that stops automatically when the tape is finished.
Equipped with built-in reel lock.
2-speed servocontrol system is adopted.
