Oyaide PA-2075 Tonearm Cable
PCOCC-A is a core component of all PA series lineup and is a key factor for high-quality and high-performance only from Oyaide Electric. Each model of PA series has its own concept and identity individualized by materials and structures.
The PA-2075 coaxial cable is a parallel-layout structure designed to be compact and lightweight. In order to reduce conductor resistance and transmit weak analog signal effectively, the overall diameter of the conductor strands was increased to 0.5sq.

The high density spiral shielding structure is composed of PCOCC-A for its highly effective behavior in an ultra compact layout.
The semiconductor (carbon PVC) layer is provided for the purpose of eliminating static electricity without exerting any influence on the conductor. As an insulator, we selected high polymer polyethylene which has the same permittivity as Teflon but is halogen-free for audio application.
The genuinely innovative product is produced by applying the latest materials and structures based on solid data. PA-2075 expands possibility and enjoyment of your life with analog audio.
PCOCC-A
PCOCC copper is a material that includes very few impurities and insures very low levels of signal disturbance. Because of its incidence of no grain boundaries, the signal passes without impediment or distortion. Heating and cooling the PCOCC wire under controlled circumstances yields a densely re-crystallized, highly pure structure called a μ conductor. The resulting product with a mirror finish applied is called PCOCC-A copper. This highly advanced product is made possible by the combined application of high technology and traditional Japanese craftsmanship.
MULTI-STRANDED STRUCTURE
A core component of PA-2075 is PCOCC-A signal transmission unit, 0.5sq diameter, and forms the Multi-stranded wire structure. Rather than twisting whole wires, the triple-layered inverted concentric structure is employed for maximum density and uniformity of wire structure and for infilling of internal space and preventing deformation among the wires. Served shielding is applied to infill internal space and to prevent deformation among the wires as well as the conductor. The number of wires used for the served shield is about three times more than the number for the conductor.
SPECIAL CHARACTERISTIC
PA-2075 was created for transmitting ultra-week analog signal. Due to the fact that its electric capacitance is set to 110.0pF/m (1kHz) and characteristic impedance is set to 44Ω, PA-2075 has excellent signal transmitting capability.

INSULATOR & OUTER SHEATH
In addition to PCOCC-A conductor, we employed halogen-free sheathing developed specifically for audio applications. It is RoHS compliant and has excellent vibration damping property due to its compounding ratio of materials. It also has superior electrical characteristic which controls the elevation of relative permittivity and attenuation of electric quantity of bass sound. The insulator is made from polyolefin which has quarter of permittivity compared to common PVC. We paid careful attention to strengthen the cohesiveness of its insulator and conductor in order to infill random space and maintain a high-quality signal transmission.
