The record player which adopted the
electronic-control direct drive motor.
The direct-drive system which the
motor itself rotates at record speed is adopted.
By the original feedback circuit, the rotating speed is kept constant.
Moreover, since it is direct-current motor, the influence by change of
power supply voltage or frequency has been prevented.
Furthermore, according to the double structure of the field coil, the
continuation pulse of a rotation magnetic field is offset and rotation
unevenness and an oscillating trouble are suppressed.
By a four-point gimbal ring original with a tone arm part dual, it is held
at 0.015g or less of level frictions, and a 0.25g very light stylus force
has realized positive trace.
Moreover, the interference to the vibration and cartridge from a drive
system is eliminated with the special vibration filter built in the balance
Equivalent to commercial M15E Super to a cartridge or the alt.
phone M20E of the model only for dual 701 with the engine performance beyond it
is adopted as it.
It unites with the rotor part of a motor for DD
system, and the turntable has realized stable rotation.
