1.3 metre Oyaide DR-510 RCA digital interconnet

In pursuit of excellence, Oyaide produced FTVS-510 by changing the conductor from 4N silver to 5N silver. Oyaide devoted much energy to providing the finest 5N silver and to researching the perfect insulator and shield for the silver conductor.

To enhance electrical conductivity of connectors as well as cable, Oyaide attached SLSC and SLSB with pure silver contacts for perfect signal transmission by pure silver. DR-510 / DB-510 represent the ultimate purity and transparency that Oyaide have pursued for the finest digital cable.

Pure Silver Conductor

Pure silver is the best material for high-speed transmission due to its excellent electrical conductivity which is far superior to high-purity copper. However, the price of silver continues to rise making it one of the rare metals.

For the core of FTVS-510, 5N jewelry grade pure silver, which is far better than industrial grade, is used. After being melted in a ceramic crucible, it is molded into 15mm diameter round bars. It is further reduced in diameter by means of 19 repetitions of the cold rolling process.

Afterwards, the silver wire is further reduced to 1.05mm by a low-speed drawing process. After the final rolling operation and mirror surface finishing, stress and strain that is generated by the drawing process is slowly removed by a lengthy annealing operation in a high-frequency electric furnace filled with inactive gas to prevent the silver from combining with oxygen. The completed ultra-pure silver wires are immediately packaged in nitrogen gas and are safely stored until the next process.

Insulator

Although the conductor is the most important factor in signal transmission, the insulator is also significant in enhancing the transmitting capabilities of the cable.

Oyaide uses a combination of PE(Polyethylene) and FEP(Teflon) which provides excellent electrical isolation and low electric permittivity. These help to enhance the transmitting performance.

For the first insulation layer, Oyaide selected PE (Polyethylene) which keeps permittivity to a minimum and enhances the flexibility of the cable. This layering of these different materials not only enhances the conductor's electric capabilities but also attenuates internal vibration by altering the resonance point.

Semiconductor layer

Although Teflon has great electric characteristics, it builds static charges easily. Oyaide needed a method to remove static electricity.

When signal flows in a cable, it generates ultra weak vibrations which cause the discharge of an electric corona.
In order to solve this problem, Oyaide installed Carbon PE as a semiconductor layer. By surrounding just the outside of the first insulation layer, this semiconductor layer helps to discharge static buildup from the Teflon layer in an orderly fashion.

Triple-layered shield

The silent background of the FTVS-510 is provided by a double-layered shielding structure. Triple-layered shielding protects against broad band noise and noise from micro-arcing.

Firstly, the semiconductor layer attenuates static noise and electric micro waves. The second copper foil shielding protects against high-frequency noise. The third is a silver plated mesh shielding, protects against low-frequency noise. It also protects against high-frequency noise by means of the skin effect on the silver plating.

Exterior

The beautiful and clear polyurethane sheathing has excellent mechanical strength and always maintains a stable level of hardness without being affected by temperature change. It can also be used outdoors because polyurethane cuts UV. Moreover, due to its high shock absorption and degree of elasticity, polyurethane provides powerful isolation from vibrations.

The SLSC RCA Plugs

The high-quality gateways of lossless signal transmission

The plugs are the gateways of signal transmission and define the quality of sound.
As the original plug of SL series, SLSC and SLSB are produced to maximum potential of cable. Oyaide employed 4N pure silver which has the highest electrical conductivity in all metals for the contact pin. SLSC/SLSB actualize transmitting high-quality and lossless sound.

Outer shell

The body and housing of SLSC/SLSB, made of brass and processed by CNC machining, are high-density and have high shielding performance compared to an existing lost-wax processed body. For its surface treatment, hard chrome plating is coated like a body of camera. The knurled pattern on the surface of SLSC enhances the handling property.

Insulator

The insulator is significant factor in enhancing the transmitting capabilities of the cable.
For the purpose of lessening signal loss, Oyaide employed Teflon which provides excellent electrical isolation and low electric permittivity.

Contact pin

The contact pin is trimmed down from 4mm 4N silver round bar by precision CNC machining. It is finished by mechanical barreling and hand polishing piece by piece.
Pure silver is the best material for high-speed transmission due to its excellent electrical conductivity which is far superior to high-purity copper.
