{"product_id":"nagaoka-mp-mono-mono-phono-cartridge","title":"Nagaoka - MP-MONO Mono Phono Cartridge","description":"\u003cp\u003e\u003cstrong\u003eA dedicated mono cartridge built around the Moving Permalloy design — for records whose musical information was only ever cut into one channel.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePlaying a mono record with a stereo cartridge works, but it is not the same thing. A stereo cartridge responds to vertical movement it should be ignoring, and what comes back with it is noise, crosstalk and groove damage rather than music. Nagaoka developed the MP-MONO specifically around monaural playback, applying its Moving Permalloy architecture — magnets and coils fixed in the body, a light permalloy element moving with the cantilever — to the problem. The result is aimed at the solidity, focus and directness that make a well-recorded mono pressing so persuasive.\u003c\/p\u003e\n\u003cp\u003eThe choice of stylus matters more on mono than it does anywhere else, because mono records were not all cut to one standard. This cartridge ships with a 0.4 × 0.7 mil bonded elliptical diamond, the 0.7 mil geometry optimised for modern record cutting, and Nagaoka's own words for the result are a clear, well-outlined image with high resolution.\u003c\/p\u003e\n\u003cp\u003eFor earlier pressings there is a second option. The JN-PMONO 1.0E replacement stylus fits this same body and carries a 0.5 × 1.0 mil elliptical diamond based on the dimensions commonly used for mono records of the 1940s and 1950s, which Nagaoka describes as reproducing thicker mid-bass and more of the air of the original. One cartridge and two styli therefore cover a collection that spans both eras — particularly useful if you buy original jazz, classical, vocal and early LP pressings alongside modern mono reissues.\u003c\/p\u003e\n\u003cp\u003eOutput is 4.0 mV into a standard 47 kΩ moving-magnet input, so no mono-specific phono stage is needed.\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003ePurpose-built mono cartridge — not a stereo design with its channels bridged\u003c\/li\u003e\n\u003cli\u003eMoving Permalloy generator, as used throughout the Nagaoka MP series\u003c\/li\u003e\n\u003cli\u003eShips with a 0.4 × 0.7 mil bonded elliptical diamond optimised for modern mono cutting\u003c\/li\u003e\n\u003cli\u003eAccepts the JN-PMONO 1.0E stylus for 1940s–50s pressings, and the JN-PMONO 0.7E as a like-for-like replacement\u003c\/li\u003e\n\u003cli\u003e4.0 mV output into a standard 47 kΩ moving magnet input\u003c\/li\u003e\n\u003cli\u003eAluminium-alloy cantilever; 6.5 g body\u003c\/li\u003e\n\u003cli\u003eMade in Japan by Nagaoka\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e MP (Moving Permalloy) mono cartridge\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage:\u003c\/strong\u003e 4.0 mV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e 20 Hz – 20,000 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStylus as Supplied:\u003c\/strong\u003e 0.4 × 0.7 mil bonded elliptical diamond (JN-PMONO 0.7E)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCantilever:\u003c\/strong\u003e Aluminium alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTracking Force:\u003c\/strong\u003e 1.5 – 2.0 g with the 0.7 mil stylus; 2.0 – 2.5 g with the 1.0 mil stylus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Resistance:\u003c\/strong\u003e 47 kΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad Capacitance:\u003c\/strong\u003e 100 pF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge Weight:\u003c\/strong\u003e 6.5 g\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplacement Styli:\u003c\/strong\u003e Nagaoka JN-PMONO 0.7E (0.7 mil) or JN-PMONO 1.0E (1.0 mil)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Half inch (1\/2\") standard mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIn the Box:\u003c\/strong\u003e Cartridge body, stylus cover, cartridge case, accessory set (shell mounting screws, washers, nuts, screwdriver), instruction manual\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Made in Japan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e Nagaoka also builds an MP-MONO 1.0E — the same body supplied with the 1.0 mil stylus fitted.
