Audio Technica - VM740xML/H - Headshell/Cartridge Combo Kit

The AT-VM740xML/H combo kit includes the AT-VM740xML microlinear dual moving magnet cartridge premounted on the AT-LT10 universal 1/2"-mount headshell. The AT-VM740xML is part of the updated AT-VMx series, which introduces material and design changes to further refine the VM sound, offering responsive playback that is especially sensitive to the dynamism of musical expression.

Features

Cartridge

• AT-VMx dual moving magnet cartridge with microlinear stylus


• Microlinear stylus tracks the record groove with incredible accuracy, providing more nuanced sound reproduction than elliptical and conical styli 


• Paratoroidal coils improve generating efficiency for enhanced channel separation, channel balance, and transient response 


• PCUHD (Pure Copper Ultra High Drawability) coils – and fewer coil turns – deliver highly responsive, three-dimensional sound reproduction with excellent transient response


• Center shield plate between the left and right channels reduces crosstalk for clear stereo sound


• Die-cast aluminium housing reduces vibrations and resonance


• 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


• Aluminium tapered cantilever reduces mass near the stylus tip for quicker signal transmission


• Compatible with any turntable headshell that accepts 1/2" cartridges


• Compatible with most AT-VMx series replacement styli,* offering a wide choice of options for every budget and application

*Excludes mono models

Headshell

• Universal ½"-mount headshell for 4-pin turntable cartridges with or without threaded inserts


• Ultra-lightweight aluminium die-cast body keeps vibration to the bare minimum


• Elongated through holes enable precise cartridge positioning and overhang adjustment


• OFC (oxygen-free copper) lead wires for exceptional sound quality


• Slip-resistant finger lift allows stylus to be placed precisely on the record


• Includes mounting screws

High 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

Since all AT-VMx and VM Series cartridges share the same body design and have a removable stylus, you can use almost any AT-VMNx or VMN replacement stylus* with any VMx or VM cartridge for easy experimentation with sound characteristics.

All in the Design>

The Vertical Magnet (VM) design closely mirrors the cutter head used to make the vinyl master

The standard cutter head (used to record the vinyl master) uses two transducer coils, mounted perpendicular to each other at 45 degrees from horizontal, to cut the channel: one in each wall of the 90 degree record groove.

The AT-VMx cartridges use the same 90 degree V-shape configuration as the cutter head. This way, the cartridge achieves accurate tracking, excellent channel separation, high definition of the stereo image and extreme clarity over the entire audio spectrum.

Audio Technica’s Story

In the early 1960s at Tokyo’s Bridgestone Museum of Art, curator Hideo Matsushita hosted LP listening concerts, where people would experience vinyl records played on high-quality audio equipment. Matsushita was moved by the positive reactions guests had to the music, but was frustrated that the expense of high-fidelity listening prevented many people from experiencing it.
