It comes fitted with a 0.4 × 0.7 mil bonded elliptical diamond intended for modern mono pressings, while an optional 1.0 mil stylus is available for earlier records cut for a wider stylus profile.\u003c\/p\u003e \u003cp\u003eLike Nagaoka's stereo MP cartridges, the MP-MONO uses a lightweight permalloy element at the rear of the cantilever rather than the comparatively heavy magnet of a conventional moving-magnet cartridge. The result is a low-moving-mass generator with 4 mV of output for a standard MM phonostage.\u003c\/p\u003e\n\n\u003ch4\u003eDesigned for Mono Records\u003c\/h4\u003e \u003cp\u003eMono LPs carry their musical information through lateral groove modulation. The MP-MONO is designed around that format rather than adapting a stereo cartridge and electrically combining its channels.\u003c\/p\u003e \u003cp\u003eThe standard JN-PMONO 0.7E stylus uses a 0.4 × 0.7 mil bonded elliptical diamond. Nagaoka developed this version for modern mono cutting geometry and contemporary mono reissues.\u003c\/p\u003e\n\n\u003ch4\u003e0.7 Mil and 1.0 Mil Stylus Options\u003c\/h4\u003e \u003cp\u003eNagaoka also offers the JN-PMONO 1.0E replacement stylus, which uses a 0.5 × 1.0 mil bonded elliptical diamond. The larger profile is intended for mono records from the 1940s and 1950s, when 1.0 mil playback styli were common.\u003c\/p\u003e \u003cp\u003eBecause the stylus assembly is replaceable, the MP-MONO body can be used with either profile. The standard 0.7 mil stylus tracks at 1.5–2 g, while the optional 1.0 mil version tracks at 2–2.5 g.\u003c\/p\u003e\n\n\u003ch4\u003eMoving Permalloy Generator\u003c\/h4\u003e \u003cp\u003eNagaoka's MP system replaces the moving magnet of a conventional MM cartridge with a much smaller piece of magnetically permeable permalloy attached to the rear of the cantilever. The magnet and coils remain stationary inside the cartridge body.\u003c\/p\u003e \u003cp\u003eReducing the mass moving with the cantilever allows the stylus to respond more freely to groove modulation while retaining the high output required by a conventional MM phonostage.\u003c\/p\u003e\n\n\u003ch4\u003eReplaceable Stylus\u003c\/h4\u003e \u003cp\u003eThe standard replacement stylus is the JN-PMONO 0.7E. The optional JN-PMONO 1.0E provides the larger stylus profile for earlier mono LPs.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eMP-MONO cartridge\u003c\/li\u003e \u003cli\u003eJN-PMONO 0.7E stylus\u003c\/li\u003e \u003cli\u003eStylus guard\u003c\/li\u003e \u003cli\u003eCartridge case\u003c\/li\u003e \u003cli\u003eMounting screws, washers, and nuts\u003c\/li\u003e \u003cli\u003eScrewdriver\u003c\/li\u003e \u003cli\u003eInstruction manual\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cp\u003e\u003cb\u003eType:\u003c\/b\u003e Moving Permalloy mono cartridge\u003c\/p\u003e \u003cp\u003e\u003cb\u003eMounting:\u003c\/b\u003e 1\/2 in.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eStylus:\u003c\/b\u003e 0.4 × 0.7 mil bonded elliptical diamond\u003c\/p\u003e \u003cp\u003e\u003cb\u003eCantilever:\u003c\/b\u003e Aluminum alloy\u003c\/p\u003e \u003cp\u003e\u003cb\u003eOutput Voltage:\u003c\/b\u003e 4 mV\u003c\/p\u003e \u003cp\u003e\u003cb\u003eFrequency Response:\u003c\/b\u003e 20 Hz–20 kHz\u003c\/p\u003e \u003cp\u003e\u003cb\u003eVertical Tracking Force:\u003c\/b\u003e 1.5–2 g\u003c\/p\u003e \u003cp\u003e\u003cb\u003eLoad Resistance:\u003c\/b\u003e 47 kΩ\u003c\/p\u003e \u003cp\u003e\u003cb\u003eLoad Capacitance:\u003c\/b\u003e 100 pF\u003c\/p\u003e \u003cp\u003e\u003cb\u003eReplacement Stylus:\u003c\/b\u003e JN-PMONO 0.7E\u003c\/p\u003e \u003cp\u003e\u003cb\u003eOptional 1.0 Mil Stylus:\u003c\/b\u003e JN-PMONO 1.0E, 0.5 × 1.0 mil bonded elliptical diamond\u003c\/p\u003e \u003cp\u003e\u003cb\u003eOptional 1.0 Mil Stylus Tracking Force:\u003c\/b\u003e 2–2.5 g\u003c\/p\u003e \u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 6.5 g\u003c\/p\u003e","brand":"Nagaoka","offers":[{"title":"Default Title","offer_id":54067273269432,"sku":"MP-MONO","price":375.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/files\/nagaoka-mp-mono-cartridge__92619-2.webp?v=1790792697","url":"https:\/\/upscaleaudio.com\/products\/nagaoka-mp-mono-phono-cartridge","provider":"Upscale Audio","version":"1.0","type":"link"}
