Audio technica VM 670SP Dual MM Stereo Cartridge for 78 RPM

Audio technica VM 670SP Dual
MM Stereo Cartridge for 78 RPM

Model dedicated to 78 RPM records, whose round stylus has a large curvature radius at the tip. The curvature radius is 3 mil, and suitable for playing 78 RPM records from a wide variety of eras.

• Aluminium cantilever
• Para-toroidal coils improve generating efficiency
• Mono body terminating left and right channels reduces surface noise
• Durable low resonance polymer housing

Para-toroidal generating system

Para-toroidal coils improve generating efficiency and offers superb linearity, since leakage of magnetic flux in this continuous and unitised magnetic circuit is low. Permeability of the cores is also optimised through the use of laminated cores.

Mono body

For monaural operation, left and right channels should be connected. A mono body on which left and right terminals are connected internally reduces record noise which is primarily in the vertical direction and obtains a highly focused ‘centre’ sound image compared with stereo bodies.
