Audio Technica AT-33xMONO/I

The Audio-Technica AT33xMONO/I is a premium moving coil cartridge designed specifically for accurate mono playback. As part of the latest AT33x Series, it introduces advanced materials and refined engineering to deliver a warmer, fuller, and more expressive sound. As a result, mono recordings gain improved clarity, stronger dynamics, and reduced surface noise.

True Mono dual moving coil design

The AT33xMONO/I uses a True Mono dual moving coil system that responds only to the horizontal movement of the record groove. Consequently, it ignores unwanted vertical noise components and extracts the pure mono signal with exceptional accuracy. This design delivers a cleaner presentation with a fuller low end and improved musical focus.

Optimized stylus for mono records

A 0.65 mil conical nude stylus allows the cartridge to follow the constant width and depth of traditional mono record grooves with precision. In addition, the newly developed suspension system uses piano wire to improve tracking accuracy. Therefore, the AT33xMONO/I achieves a controlled and natural sound, especially in the mid and low frequencies.

Advanced resonance-controlled body

The cartridge body combines die-cast zinc, aluminium, and high-rigidity polymer to reduce unwanted vibration. The zinc base improves structural stability, while the composite construction disperses resonance throughout the body. As a result, the cartridge delivers a balanced and natural presentation without emphasizing specific frequencies.

High-efficiency magnetic system

The AT33xMONO/I features a powerful neodymium magnet paired with a specially shaped permendur yoke. Together, these components create a strong and efficient magnetic circuit that improves signal generation. Consequently, the cartridge delivers excellent resolution, dynamic expression, and accurate analogue reproduction.

Pure copper signal transmission

The moving coils use PCOCC (Pure Copper by Ohno Continuous Casting) wire for smooth and consistent signal transfer. Because the copper structure contains no grain boundaries in the transmission path, the cartridge preserves fine musical details with excellent purity and transparency.

Easy installation and precise mounting

Like other AT33x Series cartridges, the AT33xMONO/I features threaded mounting holes integrated directly into the body. Therefore, installation requires only two screws and becomes especially convenient when mounting the cartridge to an integrated tonearm.
