Commentary
Belt drive player with simple design that is easy to use.
The drive system adopts a belt drive system with high technical stability, and a 30 cm aluminum die-cast turntable is driven by a 4-pole synchronous motor.
The tone arm uses an S-shaped pipe arm that is finished with precision processing technology while pursuing simplicity. It is also equipped with an inside four scan seller and a height adjustment mechanism of the arm.
SHURE's M75BM MM-type cartridge is used.
The cabinet is a solid cabinet with a plank structure consisting of hard and heavy particleboards firmly bonded together. In addition, a dome type insulator with special damper material is used for the leg part, making the structure strong against howling and vibration resistant.
