Reference Bronze

The Ortofon Reference Interconnect cables Series is designed and manufactured by Ortofon Japan. The Reference Bronze has an astonishing wide-range, clear, and neutral sound.

A combination of three conductor materials: 4N PCUHD (Pure Copper Ultra High Durability), 4N HiFC (High performance pure copper), and 4N OFC (Oxygen-free copper), the Reference Bronze deliveres an astonishing wide-range, clear, and neutral sound. Two bundles, each of 4 different kinds of conductors run in parallel and are orientated in such a way that their internal structure are kept asymmetric with respect to each other.

Quality terminal connection

Both Nickel-plated RCA terminal with rhodium plated housing and gold-plated XLR terminal guarantee a durable and quality connection.

  • Cable capacitance: 240 pF/m
  • Cable length: 1.0
  • Terminal: RCA or XLR
  • 2 pieces per set
