Part of Audio-Technica’s premium VMx cartridge series, it combines modern cartridge engineering with a stylus profile tailored to the wider grooves used in historic recordings.\u003c\/p\u003e\n\n      \u003cp\u003eUnlike standard stereo cartridges, the AT-VM670xSP uses a mono-optimised design where the dual magnets are internally connected. This configuration helps reduce surface noise and produces a focused centre sound image that better reflects the way mono recordings were originally mastered.\u003c\/p\u003e\n\n      \u003cp\u003eThe cartridge features a \u003cstrong\u003e3.0 mil conical bonded stylus\u003c\/strong\u003e, specifically shaped to trace the larger grooves of 78 RPM shellac records. This ensures reliable tracking, reduced groove wear and improved playback clarity when listening to historic recordings from early jazz, classical and vocal archives.\u003c\/p\u003e\n\n      \u003cp\u003eAs part of the VMx range, the cartridge uses high-purity PCUHD copper coils and a refined generator design to deliver fast transient response and detailed playback. Threaded inserts in the cartridge body make installation simple on standard headshells using the common ½-inch mount system.\u003c\/p\u003e\n\n      \u003ch3\u003eKey Benefits\u003c\/h3\u003e\n      \u003cul\u003e\n        \u003cli\u003eDedicated moving magnet cartridge designed for 78 RPM mono records\u003c\/li\u003e\n        \u003cli\u003e3.0 mil conical bonded stylus ideal for wide shellac grooves\u003c\/li\u003e\n        \u003cli\u003eDual moving-magnet generator with internally summed mono output\u003c\/li\u003e\n        \u003cli\u003eReduces surface noise and improves centre imaging for mono playback\u003c\/li\u003e\n        \u003cli\u003ePCUHD copper coils for improved signal clarity and transient response\u003c\/li\u003e\n        \u003cli\u003eDurable low-resonance polymer cartridge body\u003c\/li\u003e\n        \u003cli\u003eAluminium cantilever for stable tracking performance\u003c\/li\u003e\n        \u003cli\u003eThreaded inserts allow easy mounting with two screws\u003c\/li\u003e\n        \u003cli\u003eCompatible with standard ½-inch mount headshells\u003c\/li\u003e\n        \u003cli\u003eIdeal for collectors and archivists with 78 RPM record collections\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\n\n    \u003cdiv id=\"hb-at-vm670xsp-panel-2\" class=\"hb-panel\"\u003e\n      \u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n      \u003cp\u003e\u003cstrong\u003eCartridge \u0026amp; Stylus\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003eType: Dual Moving Magnet (MM) mono cartridge\u003c\/li\u003e\n        \u003cli\u003eStylus: 3.0 mil bonded conical\u003c\/li\u003e\n        \u003cli\u003eCantilever: Aluminium pipe\u003c\/li\u003e\n        \u003cli\u003eReplacement Stylus: AT-VMN70xSP\u003c\/li\u003e\n      \u003c\/ul\u003e\n\n      \u003cp\u003e\u003cstrong\u003ePerformance\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003eFrequency Response: 20 – 20,000 Hz\u003c\/li\u003e\n        \u003cli\u003eOutput Voltage: 4.7 mV (1 kHz, 5 cm\/sec)\u003c\/li\u003e\n        \u003cli\u003eHorizontal \/ Vertical Output Ratio: 20 dB\u003c\/li\u003e\n        \u003cli\u003eTracking Force Range: 4.5 – 5.5 g (5.0 g recommended)\u003c\/li\u003e\n        \u003cli\u003eVertical Tracking Angle: 20°\u003c\/li\u003e\n      \u003c\/ul\u003e\n\n      \u003cp\u003e\u003cstrong\u003eElectrical\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003eLoad Impedance: 47 kΩ\u003c\/li\u003e\n        \u003cli\u003eLoad Capacitance: 150 – 250 pF\u003c\/li\u003e\n        \u003cli\u003eCoil Impedance: 1.6 kΩ\u003c\/li\u003e\n        \u003cli\u003eDC Resistance: 375 Ω\u003c\/li\u003e\n        \u003cli\u003eInductance: 240 mH\u003c\/li\u003e\n      \u003c\/ul\u003e\n\n      \u003cp\u003e\u003cstrong\u003ePhysical\u003c\/strong\u003e\u003c\/p\u003e\n      \u003cul\u003e\n        \u003cli\u003eMount Type: Standard ½-inch mount\u003c\/li\u003e\n        \u003cli\u003eDimensions (H × W × D): 28.0 × 18.3 × 17.6 mm\u003c\/li\u003e\n        \u003cli\u003eWeight: 7.2 g\u003c\/li\u003e\n      \u003c\/ul\u003e\n\n      \u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n      \u003cul\u003e\n        \u003cli\u003eAudio-Technica AT-VM670xSP cartridge with stylus\u003c\/li\u003e\n        \u003cli\u003eMounting screws (multiple lengths)\u003c\/li\u003e\n        \u003cli\u003eWashers\u003c\/li\u003e\n        \u003cli\u003eStylus guard\u003c\/li\u003e\n        \u003cli\u003eProduct documentation\u003c\/li\u003e\n      \u003c\/ul\u003e\n\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/div\u003e","brand":"Audio Technica","offers":[{"title":"Default Title","offer_id":57583084601731,"sku":null,"price":125.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0160\/4606\/3670\/files\/at-vm670xsp_01-Photoroom.png?v=1773411722","url":"https:\/\/www.holburnonline.co.uk\/products\/audio-technica-vm670xsp-moving-magnet-cartridge","provider":"Holburn Online","version":"1.0","type":"link"}
