Oyaide Across 2000 Speaker Cable

PCOCC-A

The PCOCC-A developed by Furukawa Electric. This is an ultra pure single crystal copper originally developed by Professor Ohno. It was then further evolved into PCOCC utilizing a single copper grain wire. This design results in an extremely low level of signal disturbance and loss factor due to the lack of crystalline borders in the signal path.

Oyaide has further evolved this technology with a highly controlled heating and cooling process and improved surface management to realize a mirror finish. It is now called PCOCC-A and it is the epitome of Japanese craftsmanship.

Cross insulated stabilizer

In recent years, Oyaide has worked on vibration control of a cable. The ACROSS 2000 is a continuing evolution of this process, and now uses a newly-designed insulator. (C.I.S structure)

The C.I.S structure supports the central conductors. As a result, the mutual interaction of a center conductor and the outside sheath is suppressed to a minimum.

The ACROSS 2000 is the result of an idea to free the conductors from the sheath's vibration. Furthermore, the C.I.S structure makes not only a superior stabilizer, but also enhances the electrical characteristics, and reduces the electrostatic capacity of the cable.

Multi-Stranding-Structure

The leading part of ACROSS 2000 is signal transmission unit PCOCC-A of 2 sq mm in a parallel arrangement. 

The 7 X 7 stranding, makes the conductors more stable and removes random gaps between the wires. As a result, it minimizes and suppresses distortion. Furthermore, the conductors are twisted in a reverse direction to further minimize and suppress noise.

Characteristics

ACROSS 2000 is excellent at transmission performance and passes a signal precisely.

ACROSS 2000 has the advantage of the improvement of wideband power, and transmission loss is reduced. It also has very low capacitance (24.7pF/m 1kHz), so it is safer to use for longer runs without running into capacitance problems.

Insulating material / Outer sheath materials

As for jacket of the ACROSS 2000, the sheath material was supplied with the cooperation of Furukawa Electric, too. The halogen-free sheath conforms to the RoHS directive. It enables pure signal transmission with a high vibration attenuation characteristic by virtue of the ratios of the material.

The conductor insulation used is polymer polyolefin. The dielectric constant is 25 perecent lower compared to PVC, and random space was removed between the insulator and conductor.
