Commentary
MM type cartridge with improved performance by adopting new technology and new materials.
It uses a pivot support that provides one point support for the fulcrum of the vibration system.
Moreover, since the vibration supporting point is fixed by carefully selected jewels, there is no disturbance of mechanical impedance even if compliance is high.
We have developed and installed a C-type yoke magnetic circuit using newly developed samarium-cobalt magnet.
The shape and material of the damper rubber suitable for the pivot support system is carefully examined, selected and adopted.
The shield case is made of ultra-deep corrugated shape and high-grade 3-element permalloy material to block the influence of external magnetic field and suppress hum caused by turntable and motor.
