The AT311EP allows owners of Technics™, Hitachi™, Pioneer™* and similar linear tracking turntables with T4P plug-in connectors to enjoy the high-fidelity sound that only Audio-Technica can offer.
Designed specifically for the linear format, the AT311EP features Audio-Technica’s unique dual moving magnet construction. The dual magnet system is combined with the para-toroidal coil construction to assure an excellent sonic clarity and wide channel separation. Special Alnico magnets are employed for a natural and uncoloured sonic performance.
The AT311EP includes a universal mounting kit (P20020 adaptor P-mount to ½”) for use with other tonearms.
