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\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\nCentre shield plate reduces crosstalk\u003cbr\u003e\u003cbr\u003e\n\nA permalloy centre shield plate enables the effective separation of left and right channels, suppressing electrical crosstalk to below 40dB. This is similar to the actual crosstalk value found in the grooves of the record itself.\u003cbr\u003e\u003cbr\u003e\n\nTechnical Specifications:-\u003cbr\u003e\u003cbr\u003e\n\nType VM Type \u003cbr\u003e\nMounting 1\/2” centres \u003cbr\u003e\nFrequency Response 20 - 27,000Hz \u003cbr\u003e\nChannel Separation 28dB (1kHz) \u003cbr\u003e\nOutput Channel Balance 1.0dB (1kHz)\u003cbr\u003e \nOutput Voltage 4.0mV (1kHz, 5cm\/sec.) \u003cbr\u003e\nVertical Tracking Angle 23˚\u003cbr\u003e \nVertical Tracking Force Range 1.8 – 2.2g (2.0g standard) \u003cbr\u003e\nStylus Shape MicroLine™ \u003cbr\u003e\nStylus Size 0.12 x 2.2 mil \u003cbr\u003e\nStylus Construction Nude Square Shank \u003cbr\u003e\nCantilever Aluminium Tapered Pipe \u003cbr\u003e\nCoil Impedance 2,700Ω (1kHz) \u003cbr\u003e\nStatic Compliance 40 x 10-6 cm\/dyne \u003cbr\u003e\nDynamic Compliance 10 x 10-6 cm\/dyne (100Hz)\u003cbr\u003e \nRecommended Load Impedance 47,000Ω\u003cbr\u003e \nRecommended Load Capacitance 100 – 200pF \u003cbr\u003e\nWeight 6.4g \u003cbr\u003e\nDimensions 17.3 (H) x 17.0 (W) x 28.2 (L) mm \u003cbr\u003e\nReplacement Stylus VMN40ML","brand":"Audio-technica","offers":[{"title":"Default Title","offer_id":57413250679116,"sku":"AUDIOTECHNIKCAVM540ML","price":183.33,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Audio-Tech-VM540ML.jpg?v=1777540892","url":"https:\/\/www.stoneaudio.co.uk\/products\/audio-technica-vm540ml-moving-magnet-cartridge","provider":"Stone Audio","version":"1.0","type":"link"}
