Oyaide's AR-910 (Pair)

Interconnects by Oyaide

Manufacturer's Description:

AR-910
"5N Pure Silver"

Silver has the highest electrical conductivity of all metals. In 2005, Oyaide released the FTVS-408, a pure silver coaxial cable designed to be used mainly for digital signal transmission. Although it was produced as a limited production model, it became a regular product in their lineup due to strong customer demand. Subsequently, Oyaide produced the FTVS-510 by changing the conductor from 4N silver to 5N silver. They devoted much energy to providing the finest 5N silver and to researching the perfect insulator and shield for the silver conductor. Cable manufacturing technology has made great progress since then.

Oyaide has just introduced the FTVS-910 which has pure silver twisted pair conductors. Its unlimited transparency is represented by its beautiful exterior coated by brilliant silver. 5N pure silver wires are made by advanced manufacturing processes including the continuous casting process that takes place in a high-frequency electric furnace, 19 stages of cold rolling, a drawing process and a final annealing operation. For the insulation material, they have employed a combination of FEP (Teflon) which has the lowest level of electric permittivity and PE (Polyethylene). These help to enhance the transmission performance of the FTVS-910. Double-layered shielding whose performance has been proven in our FTVS-510 is also employed in the FTVS-910. It protects against broad band noise and noise from micro-arcing. The impedance is set to 110Ω. This means FTVS-910 can be applied for digital interconnection (AES/EBU) as well as for analog.
 
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 ever higher making it one of the rare metals. For the core of FTVS-910, 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 transmission capabilities of the cable. For the purpose of lessening signal loss, they use Teflon for the skin layer which provides excellent electrical isolation and low electric permittivity. For the first insulation layer, PE (Polyethylene) is used 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.
 
Triple-layered Shielding
When Oyaide conceived the FTVS-910 their goal was unlimited transparency. The ultra silent background of the FTVS-910 is provided by a triple-layered shielding structure. The first semiconductor layer attenuates static noise and electric micro waves. The second copper foil shielding protects against high-frequency noise. The third, 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.
 
Semiconductor Layer
Although Teflon has a great electrical characteristic, Oyaide needed to adopt a method for static electricity removal due to the fact that Teflon charges easily. 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, they 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.
 
Exterior Jacket

The beautiful and clear urethane sheathing has excellent mechanical strength and always maintains a stable level of hardness without being affected by temperature change. Moreover, due to its high shock absorption and degree of elasticity, polyurethane provides powerful isolation from vibration

Oyaide Focus 1 XLR Connectors for AR-910
Inspired by the look and feel of world class camera lenses, the Focus 1 employs several important innovations including an entirely new one touch, push-pull locking system. The ball bearing based mechanism is machined to ultra precise tolerances resulting in a connection that is smooth and absolutely positive. In addition, they have provided a unique innovation to protect equipment from POP noise at the moment of contact: The No.1 contact pin (ground) is 3mm longer than the other pins, allowing it to make contact before the other pins.
Machined Deoxidized Phosphor Bronze bar stock molded in 30% Glass filled PBT to insure high speed vibration attenuation. SILVER (1.5 micron) base plating. RHODIUM (0.3 micron) top  plating
Machined brass Hard-Chrome plated.
Left and right channels identified by SWAROVSKI rhinestones, one blue, one red.
