Dual Moving Magnet Stereo Cartridge with Microlinear stylus

Audio-Technica's VM540ML Dual Moving Magnet Cartridge features a Microlinear shaped diamond tip for improved high-frequency response with less wear and distortion.

Standard model with a Microlinear stylus. Distortion is low even on the inner circumference of a record because the curvature radius of the stylus tip does not alter even if the stylus becomes worn.

Audio-Technica's internationally-patented Dual Magnet design replicates the structure of the cutter head.
Instead of using a single, large magnet, the two magnets are arranged in the shape of a "V". The two magnets are positioned precisely to match the positions of the left and right channels in the stereo groove walls. Consequently, the VM design ensures outstanding channel separation, extended frequency response and superb tracking.

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.

Centre shield plate reduces crosstalk

A permalloy centre shield plate enables the effective separation of left and right channels, suppressing electrical crosstalk to below 40dB. This is similar to the actual crosstalk value found in the grooves of the record itself.

500 Series

Standard cartridge body fitted with the para-toroidal coils, centre shield plate, and 6N-OFC coil wire which is the same as 500 series.

Microlinear Stylus

Microlinear profile diamond stylus offers high frequency response with less wear and distortion than elliptical or conventional linear contact styli.
