A torque up motor and the record player which raised
completeness more with the high-sensitivity arm.
By adopting the DC
servo motor which improved running torque, rotation unevenness is stopped and
the stability is improved.
Moreover, the turntable has adopted the product
made from aluminum die-casting of the precision instrument manipulation finish
by which balance check was carried out completely.
The rubber sheet used
for a turntable is a 320g heavy weight class type, and is absorbing the
vibration by rotation, and the vibration between a record sound track and the
A velocity change-over switch is an electronic formula by
using of a microswitch, and can choose 33-45 rotation.
Moreover, 33 and each of 45 rotations can tune a speed control finely in
±6% of span.
As for the tone arm, the bearing part has adopted the static balance
type tone arm of MA-202 and this structure,The radial type bearing was used for
the Ain Guller type bearing original with a perpendicular bearing part, and the
level bearing part, respectively, and the initial shock perpendicular
sensitivity of 5mg or less and the initial shock level sensitivity of 10mg or
less are realized.
Moreover, the original variable type inside force canceller corresponding
to a stylus force is carried, right and left apply a stylus force equally,
and the tracing capacity of the cartridge is heightened.
The head shell has adopted H-303 which is a head shell made from aluminum
die-casting with few vibrations, and the gilding treatment has been performed
in order to prevent poor contact by secular change in a connector part.
The stylus-force coordination has adopted the point Direct-reading type
once to 0-3g, and the cartridge to 19g of self-weights serves as an enable by
attaching an optional sub wait to the rear.
The arm lifter has adopted
the oil dumping type with a smooth contact desorption with a record side.
A cabinet is the slim type which took rod new measures, and the measures
against a howling are also taken.
Output code is a low capacity type of
50 pF/m, and is also aiming at the correspondence to 4ch play.
checking of specified speed can be checked with the stroboscope and neon glow
lamp which were minced by the perimeter of the turntable.
