The curvature radius is 3 mil, and suitable for playing 78 RPM records from a wide variety of eras.\u003cbr\u003e\u003cbr\u003e\n•Aluminium cantilever\u003cbr\u003e\n•Para-toroidal coils improve generating efficiency\u003cbr\u003e\n•Mono body terminating left and right channels reduces surface noise\u003cbr\u003e\n•Durable low resonance polymer housing\u003cbr\u003e\u003cbr\u003e\n\nInstead of using a single, large magnet, the two magnets are arranged in the shape of a \"V\". The two magnets are positioned precisely to match the positions of the left and right channels in the stereo groove walls. Consequently, the VM design ensures outstanding channel separation, extended frequency response and superb tracking.\u003cbr\u003e\u003cbr\u003e\n\nPara-toroidal generating system\u003cbr\u003e\n\nPara-toroidal coils improve generating efficiency and offers superb linearity, since leakage of magnetic flux in this continuous and unitised magnetic circuit is low. Permeability of the cores is also optimised through the use of laminated cores.\u003cbr\u003e\u003cbr\u003e\n\nMono body\u003cbr\u003e\n\nFor monaural operation, left and right channels should be connected. A mono body on which left and right terminals are connected internally reduces record noise which is primarily in the vertical direction and obtains a highly focused ‘centre’ sound image compared with stereo bodies.\u003cbr\u003e\u003cbr\u003e\n\nSpecialised 600 series mono body with internal wiring dedicated to monaural sound.\u003cbr\u003e\u003cbr\u003e\n\nConical Bonded (3mil) Stylus\u003cbr\u003e\n\nA conical bonded stylus with a large curvature radius at the tip.
