Tunami GPX-Re V2

Basic

"TUNAMI" has broken new ground in the world of power cables with its high power transmission using an ultra-thick 5.5sq. (≈10AWG) conductor and strict 3-layer sealing.

With its aggressive sound and high performance, TUNAMI was a milestone in the history of power cables.

In 2013, with the end of supply of PCOCC-A conductor, the first generation "TUNAMI" was unintentionally discontinued.

However, in 2014, "TUNAMI V2" inherited the life of the original "TUNAMI" with the precision conductor "102 SSC".

In order to inherit the concept of the first generation model, the structure of "TUNAMI V2" is the same as the first generation model. It has been thoroughly refined with the 102 SSC precision conductor, giving it a new look and feel.

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 the art technologies specific to our specialized cable store. Our products reflecting such advantages offer unmatched performance.

TUNAMI GPX-Re V2 embodies an ideal fusion of State-of-Art technology and craftsmanship. It equipped with P/C-004e special edition plug.

Features

"102 SSC" - 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.

With a wire cross-sectional area of 5.5sq., it is capable of transmitting high power up to 30 amperes at a withstand voltage of 600V.

It provides high power transmission of 600V maximum 30 amps withstand voltage and aggressive response.

Short-pitch stranded wire twisted at 1.15 times the normal tension eliminates random gaps in the conductor and suppresses sound quality degradation caused by wire-to-wire distortion.

We also paid close attention to the adhesion rate between the insulator and conductor. The insulator and conductor are evenly adhered to each other, eliminating random gaps and degradation of sound quality caused by interline distortion.

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.

Exclusive AC Power Plug and IEC Connector

The "Aspirin Snow White" outer cover is specially produced for the TUNAMI GPX-Re V2.
It is made from thick Polycarbonate which strength and hardness attenuate small vibrations at high speed with no added distortion due to its superior rigidity.

In order to maximize the potential of the TUNAMI power cable, the contact is modified from phosphor bronze to beryllium copper that insures the higher level of mechanical integrity and electric conductivity. And also a combination of platinum and palladium is employed as well as P/C-004e. The thickness of the plating is optimally-adjusted for the TUNAMI GPX-Re V2.
