Dual Moving Coil Cartridge
AT-ART9
AT-ART9
Features
- Premium magnetic core moving coil type cartridge
- Builds on basic magnetic design of the limited-edition AT50ANV and vibration system of the AT-OC9/III
- Special line contact stylus and solid boron cantilever with a 0.26 mm diameter
- Neodymium magnet and permendur yoke significantly increase magnetic energy
- PCOCC used for coils and terminal pins
- Very high-quality magnetic circuit
- VC mold design ensures stability and rigidity, limiting unnecessary coil movement and reducing distortion
- Hybrid body of machined aluminum and hard plastic reduces unnecessary resonance
- Machined aluminum base
- High-separation, wide-response dual moving coil
