write this serial number on your enclosed warranty card and keep
it in a secure area. This is for your security.
Quartz PLL Brushless DC Hall Motor
This turntable's operation is based on Quartz PLL principles.
Under this system, the waveform signals from ahigh-position
reference oscillator, which incorporates a quartz oscillator, are
compared with the output waveform signals of the frequency
generator built into the rotor of the motor, and the rotation speed
of Che motor is thus controlled. This system is free from both time
and temperature drift, and it has an excellent response to changing
load requirements. It also ensures that the platter rotates ae a
precise speed.
Precision Parts for a Superb Rotation Performance
The precision-engineered center shaft and bearings (with a
centricity of less than 02µ) as well as the high- inertial-mass platter
combine with the Quartz PLL brushless DC Hall motor to yield a
speed deviation of less than 0.025% (WRMS) and asignal-to-noise
ratio of better than 73dB (DIN -B). These are specifications which
are every bit as good as those displayed by a professional-use
turntable.
Two- motor, Full-automatic Turntable with Precision
Geared Motor Mechanisms
The lead-in and return of the tonearm are performed by a
special precision geared motor mechanism which does not affect
the speed of the platter at all. Furthermore, a speed detection-type
auto-return mechanism controls the tonearm for accurate and
stable operation every time it is returned to the arm rest.
Specially Designed Cabinet to Enhance Sound Quality
and Reduce Occurrence of Howl
The cabinet features newly developed insulators, which
the talents of rubber and springs, on the 40mm-thick particle
board. This increases the internal loss and makes for superior
stability, thereby preventing howl caused by sound pressure from
arising and also canceling out vibrations from the floor. The
tonearm is mounted on a stand base which employs alarge-mass
aluminum diecast material for improved sound quality.
