Commentary
MM type cartridge incorporating technology obtained with FR-6SE.
It uses a vibration system that works in the same way as applying a DC bias to the magnetic circuit, and realizes extremely excellent linearity at small signals even though it is a.
The FR 101 se is equipped with a line-contact type diamond tip at the needle tip to improve the tracing capability in the high-frequency range.
In addition, the FR 101 has an elliptical needle at the needle tip.
