Commentary
A record player with a direct drive system.
The drive system adopts a direct drive system using a DC servo motor with large torque and a heavy-duty turntable with large inertia, and achieves stable rotation and excellent characteristics against load fluctuations.
The tone arm suppresses resonance by strengthening the joint of each component and increasing the overall rigidity.
In addition, a precision miniature bearing is used for the bearing support part to obtain high initial motion sensitivity.
Equipped with strobe.
It uses a mechanism based on mirror reflection, making it possible to check and adjust without being affected by external light conditions.
A 62 mm thick laminated plate cabinet has been adopted to reduce the influence of external vibration.
