Product Research



General Overview: The AT440MLa cartridge is equipped with Audio-Technica's patented Dual Magnet cartridge design. The cartridge features a Paratoroidal generator coil circuit and a Micro-Linear stylus. The AT440MLa uses PCOCC (Pure Copper by Ohno Continuous Casting process) in the construction of its coil and lead wires.

Micro-Linear Stylus (MicroLine): This type of stylus provides better high frequency response than an elliptical or conventional linear contact stylus.  The curving rate of the micro-linear stylus does not change until the stylus is almost worn, whereas the curving rate of conventional styli increases as they're used.  This small curving rate ensures clear and non-distorted playback over the entire frequency range, even for the inner part of the record groove where high tracing performance is typically not maintained as well by conventional styli.

Average Life: The small curving rate of a micro-linear stylus results in an average life of approximately 1,000 hours, which is typically much higher than that of conventional Audio-Technica brand elliptical styli.

Stylus Cantilever: This cartridge uses a tapered alloy tube for the stylus cantilever.

Mount Compatibility: This cartridge is compatible with Half-inch (standard mount) applications.  It cannot be used as a P-mount.
