A direct drive player that uses a quartz synthesizer continuous pitch control method.
The quartz synthesizer continuous pitch control method allows the pitch to be continuously
changed in the range of ± 8% while the quartz lock is applied.
The all-round detection FG is adopted, and the detection signal is more accurate than the
single-point detection method because detection is performed around the entire circumference
of the rotation axis.
In addition, the motor adopts a one-piece structure D.D. motor.
It uses a gimbal suspension system to achieve an excellent initial sensitivity of 7 mg
both horizontally and vertically.
It is equipped with an arm height adjustment mechanism with a locking mechanism and
a height adjustment cylinder with a precision helicoid finish that allows fine adjustment within
a range of 6 mm.
The upper part of the cabinet is made of die-cast aluminum, and the lower part is integrally
molded of heavy-weight special rubber with high vibration damping rate and excellent
vibration isolation characteristics, providing excellent vibration isolation performance.
In addition, the D.D. motor, tonearm, and dust cover mounting parts are connected to
special rubber, and thorough anti-vibration measures are adopted to isolate each part
separately. In addition, the turntable has a rubber sheet and deadening rubber attached to
the back of the turntable to further improve vibration resistance.
A slide lever system is used to adjust the pitch.
The display board can be read directly in 1% increments, and the green LED lights up at
0 points (rated speed).
It is equipped with a purely electronic braking mechanism, which brakes quickly with a single touch.
It is equipped with a pop-up stylus illuminator and can be stored in a cabinet when not needed.
It is equipped with a strobe illuminator integrated with a power ON/OFF switch.
