Commentary
S-shaped universal tone arm that uses carbon fiber.
A light and strong carbon fiber is used in the tone arm to improve tracing ability by reducing effective mass. In addition, the moment of inertia is very small and followability to the record groove is greatly improved. In addition, the problem of partial resonance in the middle range is suppressed by the structure of braided long carbon fiber and moderate internal loss.
Angular contact bearing is used in the horizontal and vertical rotating part of the arm.
Equipped with an anti-skating mechanism that does not impair horizontal sensitivity.
The arm height can be adjusted and the vertical tracking angle can be adjusted.
Equipped with an arm elevation mechanism.
PP 312 using carbon fiber is adopted for the head shell.
