Oyaide ACROSS 900 XX V2

Basic

In contrast to its simple and sophisticated exterior, the ACROSS900XX V2 is full of innovative ideas and unprecedented concepts. Products based on completely new concepts are sometimes derided as epoch-making. Over time, however, these products become legendary by establishing a solid track record.” Six years after the first ACROSS900XX, the new ACROSS900XX V2 spins a new history.

Features

“102SSC” – Oyaide Electric Precision Conductor

• To avoid impurities as much as possible, only virgin copper that does not contain any recycled copper is used in accordance with JIS C1011.
• Peeling process is applied to remove 100% of impurities attached to the surface.
• In order to facilitate the flow of electrical signals through the surface layer of the conductor, the strand is made finer using a natural diamond die to improve the surface smoothness of the strand.
• The stranded wire is processed with a processing accuracy of ±1μm, far exceeding the standard error tolerance of ±8μm.
• Two annealing processes are used to eliminate mechanical stress distortions in the strands.
• Thorough product control of manufacturing control values, maintenance, shipping days, etc. Achieved the highest conductivity of 102.3% IACS.

Patented “3E Stranded” Technology for Twisting Three Different Sizes of Wires Together

The 3E stranded structure is a concentric stranding arrangement of stranded wires in a lump-sum twisted wire conductor, and by arranging three different strand diameters, the stranding arrangement is made denser. By arranging three different strand diameters, the strand arrangement is made denser, enabling a finer conductor structure and improving conductor characteristics.

The strands of these three different conductor diameters are arranged geometrically to minimize the gaps between strands and improve strand density.

Furthermore, the outer diameter of the strands has been downsized to maintain a stable and highly accurate outer diameter, and the cross section after twisting is a perfect circle, an unprecedented conductor structure in the world. This ensures uniform adhesion between the insulator and conductor, eliminating random thickness of the insulation material and making it uniform.

CIS Structure with Air Damper

Oyaide's original cross-shaped insulation structure (CIS Structure) is used as a damper to lower the capacitance and improve the high-frequency characteristics while attenuating vibrations with its excellent stabilizing effect. The basic architecture adopts a coaxial layout to maximize the CIS Structure, which supports the center conductor at a point rather than a surface to minimize mutual interference between the center conductor and the outside.

The internal air damper layout was conceived with a completely different idea in mind. The conventional approach to vibration is to damp internally generated vibration by compounding, but the ACROSS 900 V2 does not absorb and damp vibration. The "ACROSS 900 V2" approach is based on the idea of releasing vibration, rather than absorbing and damping it.

The CIS structure not only has an excellent stabilizing effect, but also contributes greatly to the improvement of electrical characteristics. The CIS structure is made of polyolefin, which has an extremely low dielectric constant (1/4 that of PVC). These unique structures and materials give the ACROSS 900 V2 an unrivaled agile response and stress-free spatial expression.

Oyaide's Traditional Halogen-free PE Sheath Dedicated to Audio

The exterior sheath is a traditional Oyaide Electric halogen-free sheath specially designed for audio, and the Beluga color (caviar black) was chosen for its elegant and refined finish. The Beluga color (caviar black) was chosen for its elegant and refined finish, and matches any audio system without discomfort. The sheath is clearly marked with “ACROSS900 V2” and “102SSC” to indicate the V2 model.

US Made Switchcraft XLR plugs with an Established Reputation for Sound Quality

The CIS construction and the precision conductor 102SSC complete the foundation for an agile and dynamic performance. In order to maximize the potential of this original cable, the only thing needed is an excellent terminal XLR connector. We cut and tested all available XLR connectors on the market today and selected the best Switchcraft Silver Braid type to maximize the potential of the “ACROSS 900 V2”.

Oyaide “SS-47” Solder for Audio

Plugs and cables are soldered with "SS-47″, a lead-free silver solder specially designed for acoustic use. Ordinary solder has a tin purity of about 99.9% (3N) due to cost considerations." SS-47″ is made of high-purity tin that is 99.993% (4N) or higher, eliminating impurities to the utmost limit. In addition, silver and copper are added to improve conductivity and prevent solder from being eaten away.

Furthermore, the ratio of silver in a normal alloy solder is 3 to 3.5%, but in “SS-47″ a whopping 4.7% is used without hesitation. In addition, SS-47 contains 1.7% copper, which has the second highest conductivity among metals after silver. This ratio dramatically improves the conductivity, and we succeeded in setting the eutectic point at 217 degrees Celsius. Of course, these blending ratios were not determined by numerical data and workability alone.

We believe that sound quality should be the top priority for a product to be labeled as an audio solder. SS-47” is the result of numerous listening tests of prototype models with various mixing ratios.
