Audio-Technica AT-VM670xSP 3.0 mil Conical Dual MM Moving Magnet Cartridge for 78 RPM Records

Description AT-VM670xSP The AT-VMx series brings new warmth and realism to Audio-Technica’s premium dual moving magnet (MM) cartridge line, delivering an expansive soundstage that’s alive with musical detail. This latest renewal of the line introduces material and design changes to further refine the VM sound, offering responsive playback that is especially sensitive to the dynamism of musical expression. The AT-VM670xSP cartridge is designed for playing 78 RPM monaural records. The dual magnets in this cartridge are internally connected to reduce record noise and obtain a highly focused “center” sound image that stereo cartridges can’t provide.  Like all VMx cartridges, the AT-VM670xSP features PCUHD® (Pure Copper Ultra High Drawability), resulting in richer, more nuanced audio reproduction. The number of coil turns has also been slightly reduced to improve transient response, allowing the cartridge to react more quickly to signal changes for stunningly clean music with lifelike immediacy. The stylus’s 3.0 mil curvature radius makes it an excellent choice for playing 78s from many different eras. We’ve also added threaded inserts to the body of each VMx cartridge, making it easier to mount (just two screws required), especially to the integrated tonearms common on high-end turntables. And a new V-cut in the stylus’s flip-up protector provides quick reference of the stylus position, serving as a guide when lowering the stylus onto a record. Convenience Upgrades Easy to Install & Use Each AT-VMx cartridge body has threaded inserts, enabling it to be mounted to a headshell with just two screws – no nuts required. And the redesigned stylus protector now includes a V-cut for easy reference of the stylus’s position when lowering it onto a record. Premium PCUHD® (Pure Copper Ultra High Drawability) Coils Highly Efficient Generator The paratoroidal coil construction of the cartridge’s generator – two PCUHD coils per channel, one stacked behind the other – greatly improves electromagnetic performance, while a slight reduction in coil turns* enhances transient response for clean, lifelike sound. *Compared to VM series cartridges. Flexibility to Upgrade Interchangeable Styli Since all AT-VMx series cartridges share the same body design and have a removable stylus, you can use almost any AT-VMNx replacement stylus* with any VMx cartridge for easy experimentatuioin with sound characteristics.  AT-VMN10xCB (conical/bonded/aluminum cantilever) AT-VMN20xEB (elliptical/bonded/aluminum cantilever) AT-VMN30xEN (elliptical/nude/aluminum cantilever) AT-VMN40xML (microlinear/nude/aluminum cantilever) AT-VMN45xML (microlinear/nude/boron cantilever) AT-VMN50xSH (shibata/nude/boron cantilever) AT-VMN60xSL (specil line contact/nude/boron cantilever) * Excludes mono models Features AT-VMx dual moving magnet cartridge with 3.0 mil conical bonded stylus 3.0 mil conical bonded stylus designed for playing 78 RPM records Paratoroidal coils improve generating efficiency for enhanced transient response PCUHD (Pure Copper Ultra High Drawability) coils – and fewer coil turns – deliver highly responsive, three-dimensional sound reproduction with excellent transient response Threaded inserts make cartridge easier to mount, especially to integrated tonearms V-cut in the flip-up stylus protector shows stylus position, serving as a guide for lowering the stylus onto a record Durable low-resonance polymer housing Aluminum cantilever Mono body terminating left and right channels reduces surface noise Compatible with any turntable headshell that accepts 1/2″ cartridges Specifications Cartridge & Stylus Frequency Response 20 to 20,000 Hz Vertical Tracking Angle 20° Tracking Force 4.5 to 5.5 g (5.0 g standard) Stylus Construction Conical bonded (3.0 mil) Recommended Load Impedance 47 k ohms Coil Impedance 1.6 k ohms (1 kHz) DC Resistance 375 ohms Coil Inductance 240 mH (1 kHz) Output Voltage 4.7 mV (1 kHz, 5 cm/sec.)
