The fusion of creativity and high-technology

Visual Grand Prix 2008
Pure Audio Grand Prix 2008 SUMMER 



We at Oyaide Electric are always true to our convictions for the basic method of cable making. The ACROSS 2000 was produced by our challenging spirits and innovative ideas.

The conductor of ACROSS 2000 is PCOCC-A multi-stranded wire used in a manner which allows a perfect balance between conductor density and cable flexibility. The C.I.S structure diffuses vibrations into the air chamber rather then being re-absorbed into the cable structure and passed along with the signal as distortion. Its halogen-free sheath is elegant caviar black and it was specifically developed for audio use. Moreover, spiral shielding is employed for infilling of internal space

The astonishingly creative and leading-edge technology honed by decade of experience in developing cables is seemingly married with the sophisticated structure and the latest materials.



PCOCC copper is a material that includes very few impurities and insures very low levels of signal disturbance. Because of its low incidence of 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.

Cross insulated stabilizer

We have continuously been aiming to increase vibration damping property and noise protection capability of cable. ACROSS 2000 elevates interconnect cable to the new heights by applying C.I.S (Cross Insulated Stabilizer) construction developed specially for ACROSS series.

Since the C.I.S construction supports the central conductor not with surface but point, it is able to minimize mutual interference between the central conductor and the outside. And internally built vibration damper diffuses vibrations into the air chamber rather than being re-absorbed into the cable structure and passed along with the signal as distortion.

The incomparable advancement of vibration control properties and superior electrical characteristics realizes excellent performance without any loss of transmission.

Multi-stranded wire structure

The 2.0sq PCOCC-A conductor is the core component of ACROSS 2000. The parallel-arranged conductors are stranded in constant pitch in order to prevent from noise incorporation.
Rather than twisting whole wires, the triple-layered inverted concentric structure is employed for maximum density, for infilling of internal space and for preventing deformation among the wires. The number of wires used for the spiral shield is about three times more than the number for the conductor.

Special Characteristic

Although the ACROSS 2000 gives an impression of a cable which is particularly effective in diffusing vibration because of its unique architecture, it also has high potentiality for transmission performance.

We achieved to set to 24.7pF/m (1kHz), such a low electric capacitance, to enhance the power in wide range and attenuate loss of transmission. In addition, the characteristic impedance is set to 218Ω, very high impedance, for efficient signal transmission.

Insulator and 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 for lossless signal transmission.
