Commentary
A direct drive player system that uses SP-10 and tone arm EPA-99.
The SP-10 used in the turntable section is a direct-drive type turntable developed by Technics for the first time in the world.
In the direct drive system, since the motor itself rotates at the same speed as the record, there is no reduction mechanism such as belt or idler at all, thereby eliminating mechanical vibration caused by the reduction mechanism.
Turntable has weight of 2.8 kg and inertial mass of 330 kg ・ cm2Each item is strictly adjusted for dynamic balance.
Electronic switching of rotational speed by knob operation is adopted, and there is no rotational unevenness caused by switching mechanism.
In addition, the rotational speed can be finely adjusted by each of 33 1/3 and 45 revolutions.
EPA-99 is used for the tone arm part.
The EPA-99 is equipped with a newly developed Perfect Inside Force Canceler, which uses a special structure combining two cams to cancel out harmful inside forces.
Equipped with a balance weight of needle pressure direct reading type.
It uses a floating system wood base combining viscoelastic material and spring to prevent acoustic feedback and cut vibration across the range of audibility area. It also prevents howling due to external vibration and realizes more faithful sound.
Equipped with an oil dump type arm elevation mechanism.
2 head shells and dust cover are included.
