The direct-drive player which adopted the power
transformer isolation structure.
The structure which separated the power
transformer from the main unit is adopted, and total S/N as a player system is
improved. According to this outer power transformer structure, the influence of
the leakage flux to the bad cartridge and low-power-output type cartridge of a
shielding was also suppressed few, and has obtained a clearer play sound.
Moreover, two outlets for AC are arranged.
The 20 pole 60 slot
brushless DC servo motor is adopted as a motor part, and the outstanding
property has been acquired.
Moreover, the large-sized turntable made from
aluminum die-casting of inertial-mass 330 kg-cm2 is adopted as a
turntable, with original casting, density is equalized and the deflection in 900
rotations by a balancing machine is suppressing within 2g to the average of 4g
of a general high-class player.
The high-density sheet (315g and about 1.2g
per cm2) was adopted as the rubber sheet of a turntable, and the
vibration is prevented.
The tone arm serves as a universal type static
In order to pull out the tracing capacity of a cartridge, the
functionality of a tone arm is reexamined,The high-precision pivot and the
original Ain Guller type bearing were combined with the perpendicular bearing
part of the rotation fraction, and the performance with an initial shock level
perpendicular sensitivity of 10mg or less has been obtained at the level bearing
part using the radial type bearing to two upper and lower sides.
In order to check the longitudinal balance of an arm with the height of
a using cartridge, the hericoid type arm height adjustment mechanism is
carried. It can tune finely in 6mm according to this adjustment mechanism.
order to carry the variable type inside force canceller corresponding to a
stylus force, and for the amount of cancellations to face according to the
record perimeter and inner circumference according to the original variable type
structure corresponding to a stylus force and to change,The right-and-left
unbalance of the stylus force by an inside force can be canceled, and the
tracing capacity of a cartridge is raised.
The arm lifter makes smooth the contact desorption of a record side and
the needle point in the latency operation by an oil dumping type.
The head shell had adopted the product
made from aluminum die-casting with few vibrations, the gilding treatment was
performed to the connector pin, and poor contact is prevented. Moreover, the
canting coordination screw of the head shell is prepared in the head nowait-lock
connector part at the leading end of an arm, and a perpendicular coordination is
A rotational-speed switching is an electronic formula by a
microswitch, and a fine tune can be performed in ±6% of span at each velocity.
The cabinet has adopted the dual structure of a die-casting frame and
the solid base, and the measure against a howling is also checked.
player leg is equipped with the large-sized absorber, and a height coordination
The stroboscope of the mirror type which has arranged the
precision stroboscope on the back side of a turntable is carried.
code serves as a low capacity type of 50 pF/m, suppresses the influence on a
high region property, and also supports 4ch play.
