Audio Excellence Award 2006 / Visual Grand Prix 2006

MJ Technology of the year

The "TUNAMI" is a powerful, high-speed and dynamic cable of a new generation. The short-pitch stranded PCOCC-A wire which has 5.5sq cross-section area actualizes high-power signal transmission. Its voltage endurance is 600V and maximum amperage is 30A. For noise protection, we specially developed the triple-layered shielding structure. It not only rejects internal and external noise, but also instantaneous spark noise due to vibration.

From the deep stillness of TUNAMI, you can even sense the atmosphere of pre-performance of sound source. Since the day of our establishment in 1952, we at Oyaide Electric had opportunities to apply a number of State-of-ART technologies specific to our specialized cable store. Our products reflecting such advantages offer unmatched performance.

TUNAMI GPX embodies an ideal fusion of State-of-Art technology and craftsmanship. It equipped with P/C-046 special edition plug and connectors which was highly-regarded in the US and Japanese market.

After the deep analysis for insulator, we selected polymer polyolefin that has different degree of hardness at interior and exterior to prevent negative effect by sympathetic vibration. Moreover, this material has a quarter of permittivity compared to common PVC and 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.

As the leading specialists in Japan, we have continuously concentrated on developing the ideal cable and its accessories for more than 20 years. Although we have realized that there are a few variations of connectors, even though there are many variations of cables exist on the market. Finally, by applying years of technical experience and know-how, we have achieved to release L/i 50 EXs with our original "P/C-037" connectors.

The structure of L/i 50 series is star-quad structure which we have trusted for 20 years. Due to its cancellation effect of opposed wires, it blocks internal and external noise without increasing electric capacitance. For the connector of L/i 50 EXs, we employed our original connector: P-037 and C-037. The highly transparent sound character of P/C-037 accurately describes the edge of sound source.

Under the strict quality-control, the all components are made from fine material and enhanced their accuracy domestically. In other words, it is completely MADE IN JAPAN.

PCOCC-A

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.

Triple-layered shielding

We have advocated the importance of noise protection which becomes a defining feature of power cable. Although we accomplished certain results by applying star-quad shielding structure to L/i 50 series, considering customer demands and trends, we pursued producing updated product with a state-of-art technology. For TUNAMI, we developed triple-layered shielding structure.

The first layer of this structure converts electromagnetic wave into thermal energy by interfusing electromagnetic insulator. As the second layer, semiconductor layer (carbon) is employed for its characteristic that discharges static electricity without affecting its conductor. A copper foil shielding is set as the third layer to protect the conductor from external noise. Furthermore, drain wires, closely-situated to copper foil shield, make S/N ratio higher by connecting to earth ground.

Their excellent traction control and flexibility are achieved by integrating four different types of materials. The double-layered noise protection system is composed of copper foil and solid-state carbon. Its PCOCC-A multi-stranded structure enables the infilling of random spaces inside the cable and prevents deformation among the wires.

The exterior colors are Mars Violet for PA-22 and Ash Blue for PA-23 that express elegance and sophistication.

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.
