Audio Technica VM740ML Dual Moving Magnet Stereo Cartridge

VM740ML Dual Moving Magnet Stereo Cartridge, by Audio Technica.

High-end model featuring a Microlinear stylus in an aluminium die-cast alloy body. In addition to outstanding high-frequency reproduction, this model enables clear sound image localisation.

Instead of using a single, large magnet, the two magnets are arranged in a V-shape. 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 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.

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.

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.

Top-end model fitted with the die-cast aluminium alloy housing. The body reduces the unwanted vibration and enhances the superior sound quality of high-performance line contact styli.

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