Commentary
Belt drive player with semi-automatic mechanism for high cost performance.
Uses 4-pole hysteresis synchronous motor with less vibration developed exclusively for the turntable.
The belt is made of highly accurate polyurethane.
A 30 cm aluminum die-cast turntable is used for the turntable part.
It employs a newly developed universal tone arm and incorporates an arm lifter and an inside force canceler.
Equipped with semi-auto mechanism capable of auto return and auto cut.
IM-type cartridges are used. Since the shell is an international standard, the cartridge can be replaced.
The output code is a low-capacity type without high-frequency loss.
