The manual type record player which employed the
merit of the unit design efficiently as it was like the high-end model.
Usually, there were two kinds, PL-30 of a version and PL-30L which carries a
silence lift up functionality.
The phone motor of SH and a rotor scheme
is carried in the actuator like a high-end model.
According to the structure
which moved the supporting point (bearing) of the rotor which suited the motor
bottom conventionally to immediately under the turntable, it has succeeded in
the sharp reduction of a wow and flutter, and the outstanding property is
Furthermore, the Quartz PLL DC servo hall motor of starting torque
1.3 kg-cm was adopted as the motor, and stability which does not cause a load
variation to a 200g load intensity by combining a large-sized turntable with the
inertial mass of 330 kg-cm2 is realized.
Moreover, the detailed
noise is proposed to the magnetic pole change organization of a motor by
searching for the manipulation precision of micra order until it is using three
hall devices which Pioneer developed and also results in the part of a detail.
The turntable sheet excellent in the acoustic feature is adopted as a
In order to suppress the low-pass vibration produced by the curvature and
decentration of a record, the silicon oil braking scheme (on/off is possible)
It is a scheme which a braking fin sinks in the
silicon poured into the oil cup, and applies viscous braking to an arm by
pushing the dyne ping knob of an arm axis upper portion,And it is designed by
cutting the leading end of a braking fin (the shape of a ring) into 45 degrees
apply braking for which it was horizontally and perpendicularly suitable,
While this suppresses a harmful low-pass vibration, cross
modulation distortion which has an ill effect harmful to an audio frequency band
is reduced sharply.
Neither a variation per hour nor the viscous transition
by a temperature is in oil, and the silicon oil which is excellent as braking
oil is adopted. Furthermore, it is what has a high robustness where oil oozes, and which does not have し by storing this silicon oil in the oil cup made with
The arm base of die-casting nature which gave the
stabilizer effect is adopted.
Moreover, it is adopting the mass
centralization system which had adopted as the arm the long type arm of 250mm of
effective lengths who use a high-rigidity aluminum pipe, and also brought the
main wait close to an arm axis,The moment of inertia of an arm is reduced and
the basic performance of an arm itself [ before applying oil braking ] is
In order to suppress an oscillation of a howling etc., the
high-density cabinet which selected the needle-leaf tree carefully is adopted as
Furthermore, the large-sized insulator of the newly developed low
centroid structure is adopted as the insulator supporting a cabinet, and it has
become it with the design strong against the oscillation from the outside.
Using an optional dumping coordination adapter can adjust on the level
to 1-5 like PL-70, and it becomes the amount of level braking variable arm which
can be dealt with the compliance of all cartridges.
Moreover, when equipping
with the heavy cartridges (alt. phone SPU-GT type etc.) of a self-weight, the
using of an optional switching wait is recommended.
In PL-30L, the
silence lift up functionality in which the exact and quiet operation was
realized is carried.
The moving coil scheme which applied the principle of
operation of the speaker to the elevation organization in which an arm is made
to go up and down first is adopted, and a uncontacted operation is carried out
on DC voltage.
Furthermore, the termination location detection of a record
sound track has adopted the scheme which performs a uncontacted detection with
the hall device attached to the interior of an arm axis, and the magnet
countered and attached to this.
Furthermore, a silence lift up organization
is interlocked with and the pure electronic quick stop organization in which a
turntable is stopped in an instant is carried.
