The Audio-Technica AT33xMONO\/I is a True Mono dual moving coil cartridge whose coils respond only to horizontal groove movement, cutting out vertical noise for a clean, centred mono image. A 0.65 mil conical nude stylus on a duralumin pipe cantilever, PCOCC coils at the fulcrum, a neodymium magnet, and a composite body with a die-cast zinc base to disperse resonance. Suitable for mono and stereo records.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3 dir=\"ltr\"\u003eA Cartridge Dedicated to Mono\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eMono records carry their information in the horizontal movement of the groove. A stereo cartridge also reads the vertical movement, which in a mono pressing is just noise from groove wear, light damage and surface imperfections. The AT33xMONO\/I is designed to ignore it.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt is built on the AT33x Series platform and brings the series' die-cast zinc body and dual moving coil architecture to dedicated mono playback. It is aimed at collectors of mono pressings, vintage jazz, classical and early rock, and at anyone building a growing mono shelf.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eTrue Mono Dual Moving Coil\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThe AT33xMONO\/I uses a True Mono dual moving coil design, with its PCOCC (Pure Copper by Ohno Continuous Casting) coils arranged horizontally and positioned at the cantilever's fulcrum. The generator produces a signal only from horizontal groove movement, so the output is unaffected by vertical modulation. The result is reduced surface noise, a stronger low end and a cleaner, more solid centred mono image than a stereo cartridge summed to mono. A neodymium magnet provides clean, dynamic signal transmission.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCompliance remains appropriate in the vertical plane, so the cartridge can also be used safely on stereo records. Because it has two coils, it connects to a stereo system and delivers authentic mono reproduction through both channels.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003e0.65 mil Conical Nude Stylus on a Duralumin Cantilever\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eA 0.65 mil nude conical stylus is purpose-built for the consistent width and depth of mono record grooves, giving faithful tracking and natural sound. It is mounted on a rigid duralumin pipe cantilever that tapers toward the stylus tip for improved response, linked to a firm suspension mechanism that slightly lowers the dynamic compliance.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eA Composite Body That Disperses Resonance\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eLike the rest of the AT33x Series, the body combines die-cast zinc, aluminium and high-rigidity polymer, arranged to minimise and disperse resonance and vibration throughout the cartridge. The result is an even, natural tonal balance without frequency coloration, with lifelike mid-to-low frequencies.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003eEasy to Mount\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eThreaded mounting holes make it easy to fit to most headshells and tonearms. A non-magnetic screwdriver, brush, washers, mounting screws in three lengths and a protector are all included.\u003c\/p\u003e\n\u003ch3 dir=\"ltr\"\u003ePlease Note\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eAt 0.42mV output the AT33xMONO\/I is a low-output moving coil cartridge, so it needs a phono stage with an MC input, or a step-up device.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2 dir=\"ltr\"\u003eFeature Cards\u003c\/h2\u003e\n\u003ch3 dir=\"ltr\"\u003e🎙️ True Mono — Horizontal Signal Only\u003c\/h3\u003e\n\u003cp dir=\"ltr\"\u003eHorizontally arranged coils respond only to horizontal groove movement, so vertical noise doesn't reach the output.
