Koruderu structure
"DST-75R V2" is based on the primary DST-75R, is a refined model was changed to precise conductor 102SSC the conductor from PCOCC-A. Structure inherited primary DST-75R. That is a 75Ω coaxial cable with less dielectric loss due to the insulator to the utmost limit. Its biggest feature is "Koruderu structure". Between the center conductor and a polyethylene tube, through a polyethylene cord is a structure provided with an air layer between the inclusions. As a result, the dielectric loss due to insulator is suppressed to the limit, to achieve ultra-low-loss coaxial cable.
Precision conductor 102SSC
"DST-75R V2" has adopted the precise conductor 102SSC the center conductor and the braided shield. Precision conductor 102SSC in order to avoid as much as possible contamination of impurities, using only virgin copper which does not contain any recycled copper among the copper that conforms to the JIS C1011. 100% removal of the impurities adhering to the surface by performing peeling process. To facilitate the flow of electrical signal flowing through the conductor surface layer, thinned with natural diamond dies, improve the surface smoothness of the strand. It thinned wire by the machining accuracy of the standard error tolerance ± 8μm far surpass ± 1μm a. In stranded wire process, it adopted the world's first high-density different 径導 body 3E twisted structure (patented). Increase the density and roundness of strands, stabilize the electric characteristics. Annealing processing over 2 degrees, eliminating the mechanical stress-strain of the strand. Product management and thorough manufacturing control numerical value, maintenance, and shipping dates. Conductivity is achieved 102.3% IACS of the highest class.
Vetted the material and the shield
"DST-75R V2" has adopted the flex PE to satisfy both the electrical properties and flexibility to the exterior sheath. Shield measures is also thorough. In the "DST-75R V2", copper foil shield, which boasts a 100% shielding rate, with double shielding by shielding rate of 90% of the braided shield, and strictly protect the signal conductor.
Silver rhodium-plated RCA plug
To "DST-75R V2" has adopted the silver-rhodium-plated in the contact portion of the RCA plug. Body and cover using the brass of high precision machined products, is due to of course the original design and manufacture of ELEC electricity. The combination of a high-quality RCA plug and cable, or 75Ω coaxial digital signal of the S / PDIF, the transmission of the composite video signal between the video equipment, will demonstrate how, without its performance.
Using the acoustic dedicated solder "SS-47"
Plug and cable is soldered at the acoustic-only lead-free silver solder "SS-47". Normal solder purity of the tin from the cost is 99.9% (3N) degree. "SS-47" further discharge the impurities increase the purity to the limit, adopt a high-purity tin that indeed 99.993% (4N) or more. Further improvement of the electric conductivity, are designed to prevent leaching of solder, was blended silver, copper. Moreover, the case of normal alloy solder, silver mixing ratio of is from 3 to 3.5 percent, but "SS-47" is an amazing unsparingly put the amount of 4.7%. In addition, 1.7% compounded the next in high conductivity copper of silver among metals. Conductivity by this compounding ratio is dramatically improved, it succeeded in setting the eutectic point 217 degrees. Of course, the blending ratio of these, it has not determined only by numerical data and workability. To hit the solder and the inscription for the audio, the sound quality is considered to be appropriate to the highest priority. I was born that "SS-47" of the many times that there is no hearing test a proto model of a variety of blending ratio.
