701
Commentary

A record player with an electronically controlled direct drive motor.

It uses a direct drive system in which the motor itself rotates at record speed.
A unique feedback circuit keeps the rotational speed constant, and since it is a DC motor, the effects of fluctuations in power supply voltage and frequency are prevented.
In addition, the double structure of the field coil cancels out the continuous pulses of the rotating magnetic field, thereby suppressing uneven rotation and vibration trouble.

The tone arm part has dual unique 4-point gimbal, and horizontal friction is maintained at 0.015g or less, and reliable tracing is realized with 0.25g ultra-light needle pressure.
A special resonance filter built into the balance weight eliminates resonance from the drive system and interference with the cartridge.

The cartridge uses the Orthophone M20E exclusive model for the dual 701, which has the same or better performance than the commercially available M15E Super.

Since the turntable is a DD type, it is integrated with the rotor section of the motor to achieve stable rotation.
