PCOCC-A

PCOCC copper is a material that includes very few impurities and insures verylow levels of signal disturbance. Because of its incidence of no grainboundaries, the signal passes without impediment or distortion. Heating andcooling the PCOCC wire under controlled circumstances yields a denselyre-crystallized, highly pure structure called a μ conductor. The resultingproduct with a mirror finish applied is called PCOCC-A copper. This highlyadvanced product is made possible by the combined application of high technologyand traditional Japanese craftsmanship.

Multi-Stranded structure

A core component of PA-2075 is PCOCC-A signal transmission unit, 0.5sqdiameter, and forms the Multi-stranded wire structure. Rather than twistingwhole wires, the triple-layered inverted concentric structure is employed formaximum density and uniformity of wire structure and for infilling of internalspace and preventing deformation among the wires. Served shielding is applied toinfill internal space and to prevent deformation among the wires as well as theconductor. The number of wires used for the served shield is about three timesmore than the number for the conductor.

Special charactoristic

PA-2075 was created for transmitting ultra-week analog signal. Due to thefact that its electric capacitance is set to 110.0pF/m (1kHz) and characteristicimpedance is set to 44Ω, PA-2075 has excellent signal transmittingcapability.

Semicondoctor layer

A core component of PA-2075 is PCOCC-A signal transmission unit, 0.5sqdiameter, and forms the Multi-stranded wire structure. Rather than twistingwhole wires, the triple-layered inverted concentric structure is employed formaximum density and uniformity of wire structure and for infilling of internalspace and preventing deformation among the wires. Served shielding is applied toinfill internal space and to prevent deformation among the wires as well as theconductor. The number of wires used for the served shield is about three timesmore than the number for the conductor.

Insulator & Outer sheath

In addition to PCOCC-A conductor, we employed halogen-free sheathingdeveloped specifically for audio applications. It is RoHS compliant and hasexcellent vibration damping property due to its compounding ratio of materials.It also has superior electrical characteristic which controls the elevation ofrelative permittivity and attenuation of electric quantity of bass sound.
Theinsulator is made from polyolefin which has quarter of permittivity compared tocommon PVC. We paid careful attention to strengthen the cohesiveness of itsinsulator and conductor in order to infill random space and maintain ahigh-quality signal transmission.

Connectors (PA-2075 DR / RR / LDR)

The original 5PIN phono plug & RCA plug are plated by rhodium to preventthe corrosion of the contacts. For inner insulator, PTFE (Teflon) is employedfor its low-dielectric permittivity to attenuate signal loss. The RCA plug ismolded into the cover after soldering process to attenuate vibration. Moreover,the outer cover is machined by NC machining one by one.
