 Audio Cable OFC Series

AL type:
Gold-plated phono plugs provide excellent corrosion resistance.

Since RCA-type phono plugs are normally inserted and removed many times, they must be highly resistant to abrasion and provide superior conductivity even after extended use. Another important consideration is the ability to withstand corrosion which can be caused by sulfuric gases and other contamination in the atmosphere.
The thick gold plating of the plugs perfectly fulfills all of these requirements.

ALC type:
Cannon type connectors.

To accommodate equipment with Cannon (XLR) type connectors, Accuphase offers these cables with 3-pin Cannon type XLR connectors. In compliance with the BTS standard, pin is connected to the shield.

The Accuphase Oxygen-Free Copper Series cables use a densely braided outer conductor of oxygen-free copper, reliably shielding the two twisted internal conductors also made of highly pure copper. The result is a high-quality cable with negligible transfer losses and excellent resistance to induced noise. The superb performance of these cables ensures that the sonic character of top-quality audio components connected in a system is fully preserved. Listeners are able to enjoy utterly natural, well-balanced sound that gives free expression to the full musical spectrum.

Center conductor core wires are a combination of highly pure oxygen-free copper wires and silver-plated soft copper wires, providing excellent transfer characteristics.
Center conductors are formed by a combination of two types of highly pure oxygen-free copper wires of different diameter and a silver-plated soft copper wire type with low resistance. The insulation layer consists of polyethylene with high dielectric resistance and foamed polyethylene, resulting in a triple layer configuration, implemented in a dual-core design. Transfer losses as well as DC resistance are minimal.
Shielding is provided by 192 ultra-fine 0.1 mm high-purity copper wires braided to a high density, plus a layer of aluminum foil tape. This dual approach results in low capacitance and gives extra protection against any form of externally induced noise.
