AMG Turntables 12J2 Tonearm
Prefer to hear it first? We can arrange a demonstration in your own home across Suffolk, Essex and the surrounding areas, with set-up by people who actually listen.
Overview & specification
The original 12 inch tonearm design incorporating AMG‘s self developed dual pivot bearing technology, for maximum agility and low-friction performance.
High-precision radial axle horizontal bearing with highly accurate adjustable magnetic anti-skating system.
Balanced and powerful sonic performance with excellent spatial depth and dynamics across the entire audio spectrum.
Fine adjustability of all critical setup parameters for perfect trackability and maximum dynamic performance across a wide range of compatible phonograph cartridges.
The magnetic anti-skating system :
Highly accurate and adjustable magnetic anti-skating mechanism for perfectly centered and distortion-free groove tracking.scanning.
The VTA :
Precise fine tuning and repeatable adjustment of tonearm height by means of integrated bubble level and vertical threaded adjustment rod.
The integrated azimuth–adjustment :
Precise adjustment of aziumth at the bearing allows for optimization of channel performance while allowing a fully rigid connection at the headshell, for unparalleled sonic imaging.
The counterweight as the basis for dynamics :
Two-piece counterweight for perfect weight adjustment. Significantly higher dynamics and sonic precision through optimized force / mass distribution throughout the tonearm system. The kinetic energy remains in the cartridge and guarantees vibrational isolation, resulting in excellent control and clarity of bass response.
The Internal Wiring :
Gold-plated plug connections and hand made wiring with special winding pattern to cancel magnetic field resonances, resulting in the highest acoustic transparency, detail, and presence.
The arm tube :
Precisely calculated ratio of wand diameter / length effective length matched with specifications of the high-grade aluminum arm material ensures the lowest possible resonance behavior.
