It weighs 9.2g bare, and Ortofon publishes the combined cartridge-and-headshell weight for every premounted 2M at 16.7g — which is the number to check against your arm’s counterweight range before ordering.\u003c\/p\u003e\n\u003cp\u003eThe cartridge is the 2M Blue: a nude elliptical diamond at r\/R 8\/18 µm on an aluminium cantilever, 5.5mV output, 80 µm tracking ability and 25dB channel separation. It shares a generator with the 2M Red, and every bit of the performance gain over that model comes from mounting the diamond nude rather than bonding it to a metal shank — enough to lift tracking ability by 10 µm and separation by 3dB.\u003c\/p\u003e\n\u003cp\u003eOne thing worth being straight about, because a lot of retail copy is not: Ortofon markets premounted cartridges purely on convenience. It never claims the cartridge arrives aligned, never quotes a factory overhang figure, and never names an alignment geometry. What you are buying is the fiddly part already done — the cartridge bolted to the headshell with the leadwires connected, which is the step that costs most people their patience and occasionally a cantilever. You still set overhang, tracking force and anti-skate yourself.\u003c\/p\u003e\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eOrtofon 2M Blue premounted on an SH-4 headshell, leadwires connected\u003c\/li\u003e\n\u003cli\u003eBayonet \/ SME fitting for S-shaped tonearms with a universal mount\u003c\/li\u003e\n\u003cli\u003eCombined weight 16.7g\u003c\/li\u003e\n\u003cli\u003eAnodised aluminium headshell with gold-plated terminal pins and a long finger lift\u003c\/li\u003e\n\u003cli\u003eNude elliptical diamond, r\/R 8\/18 µm, on an aluminium cantilever\u003c\/li\u003e\n\u003cli\u003e5.5mV output, 80 µm tracking ability, 25dB channel separation\u003c\/li\u003e\n\u003cli\u003eQuad-coil generator with split pole pins and OFC coil wire\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 Moving magnet stereo cartridge premounted on an Ortofon SH-4 headshell\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bayonet \/ SME.
