{"product_id":"grado-prestige-1-green-mm-cartridge","title":"Grado Prestige 1 Green MM Cartridge","description":"The newly redesigned Black1 and Green1 have had their coil design reconfigured, and the effective moving mass of their generating system has been reduced by 17%. The Black1 and Green1 models use a three piece OTL cantilever technology, standard oxygen free wire in the coils and Grado's specially designed elliptical diamond mounted in a brass bushing. The Green1 model is selected from the Black1 production run and meets higher test specifications. Approximately 15% of the production run will meet these standards and become Green1 models.\u003cbr\u003e\u003cbr\u003e\n\nFrequency Response: 10-50 \u003cbr\u003e\nPrincipal: MI \u003cbr\u003e\nChannel Separation at 1KHz: 30 \u003cbr\u003e\nInput Load: 47K \u003cbr\u003e\nOutput at 1KHz 5CM\/sec.: 5mV \u003cbr\u003e\nRecommended Tracking Force: 1.5 \u003cbr\u003e\nStylus Type: E \u003cbr\u003e\nInductance: 45mH\u003cbr\u003e \nResistance: 475\u003cbr\u003e \nCompliance CUs: 20 \u003cbr\u003e\nStylus Replacement: U \u003cbr\u003e\nMounting: S\/P \u003cbr\u003e\nWeight: 5.5 ","brand":"Grado","offers":[{"title":"Grado Prestige 1 Green MM Cartridge","offer_id":57405966516556,"sku":"gr0215","price":91.63,"currency_code":"GBP","in_stock":true},{"title":"Grado Prestige 1 Green MM Stylus","offer_id":57415715160396,"sku":"GR0265","price":54.13,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1053\/6891\/2204\/files\/Grado-Pres-1-Green.jpg?v=1777451642","url":"https:\/\/www.stoneaudio.co.uk\/products\/grado-prestige-1-green-mm-cartridge","provider":"Stone Audio","version":"1.0","type":"link"}
