The universal type tone arm designed always
demonstrate the performance of a cartridge.
The inside force canceller
using a magnetic-repulsion action is carried.
Since this scheme does not have the frictional resistance or the temperature
change of the organization itself unlike the thing of the principle of
the scheme fished with thread, or a lever, the always fixed ability is
acquired and it is enabling the outstanding disk play in every location
on the record board.
Since it can fluctuate also in a record
performance, a bias coordination while carrying out a hearing is possible for
the amount of denials.
The height control organization of the hericoid
type which combines with all types of phone motor or a cartridge, and can carry
out variable [ of the height of a tone arm ] so that it can do is carried.
The arm lifter which uses high viscosity silicon oil without the care about the performance degradation by an oil leakage or a temperature is carried.
The tone arm has adopted the static balance scheme.
Furthermore, it
is designed by the weight of two kinds of attached gravities maintain a balance
completely from about 11g to 33g.
Once it maintains a lateral balance
with the design which set the needle point, and an axis of revolution and a
weight axis on the straight line, even if it will change a stylus force by a
main wait, a balance does not collapse.
The multiple asynchronously
communicating hosts to which the attached lightweight shell can make the needle
point location of a cartridge exact is attached.
Moreover, ±2 degree
variable is possible for the degree of level of a shell.
