Audio-Technica 440MLa Cartridge
CONNECTION TO SYSTEM: Run two shielded audio cables from the cartridge/tone arm connections on the turntable to the magnetic phono inputs on the amplifier or receiver. Observe Left and Right channel markings. A separate ground wire usually comes attached to the turntable, and should be connected to the ground screw found on the back panel of most electronics.
FINAL ADJUSTMENT: Reinstall stylus assembly. Following the procedure given in the turntable/tone arm instructions, carefully set tracking force to approximately the middle of the range shown for your model in the specifications table. A tracking force outside the given range can result in increased distortion and excessive record and stylus wear. Other tone arm adjustments provided such as stylus overhang and anti-skating, should be set according to manufacturer's instructions to obtain the best performance. For safety, keep the stylus guard down whenever the turntable is not in use.
OPERATING SUGGESTIONS: The low tracking force and high compliance of Audio-Technica cartridges provide the highest level of performance available, but also make them susceptible to damage if handled improperly. Most stylus damage is caused by rough treatment while the tone arm is being operated by hand. A finger should always be placed under the tone arm finger lift, never over it. A damped cueing device which lowers the tone arm gently to the record is found on many record players and should be used regularly for greatest protection of the stylus and records. Distorted or unbalanced sound from the two phono channels often can be traced to wires interchanged or touching at the cartridge terminals. A reduction in output or muffled sound may result if the stylus assembly is not fully seated. Hum from the phonograph input usually can be traced to a bad audio cable or absence of the separate ground wire from turntable to amplifier.

This AT440MLa cartridge is equipped with Audio-Technica's patented Dual Magnet cartridge design and delivers “PRACTICALLY IDENTICAL TO THE CUTTER HEAD” performance. Additional features include a Paratoroidal generator coil circuit, a Micro-Linear stylus, plus other advanced designs for top performance. Please read instructions thoroughly before using the cartridge. The AT440MLa uses PCOCC (Pure Copper by Ohno Continuous Casting process) in the construction of its coil and lead wires. Its advanced MicroLine™ stylus produces better high frequency response with less wear and distortion than elliptical or conventional linear contact styli.
