Atlas Ailsa OCC XLR Interconnects

Ailsa OCC XLR by Atlas Cables features an unusually sophisticated specification for an interconnect at this price point. The result is a beautifully balanced, open, accurate, natural sound, which we think defines a new performance standard at this level. It is an ideal upgrade choice.

The Ailsa OCC XLR is a wide-bandwidth interconnect designed to maximise the performance of high-performance audio systems using the increasingly popular XLR connectors. It incorporates the precision dd (dual-drain) system.

A symmetrical interconnect featuring four central multi-core conductors of ultra-high purity OCC (Ohno Continuous Casting) copper encapsulated within a microporous PTFE dielectric. Termination is with our aluminium alloy dark Chrome XLR connectors with silver-plated OCC copper pins.

Atlas based the dual-drain configuration on techniques originally developed for the top-of-the-range Mavros and Asimi interconnects. Twin symmetrical drain wires connect the screen to the cable return/plug interface, allowing cable termination without distorting, twisting or mechanically stressing the precision-laid screen. Typically, screened cables suffer from screen distortion when prepared for production. Cutting and twisting the screening braid has a measurable impact, effectively changing the impedance and, therefore, the cable’s performance.

The benefits are maintaining a constant low impedance load to the plug and total 360-degree screening against noise and signal degradation caused by RFI (Radio Frequency Interference).

Technology

• OCC XLR Connector - Atlas XLR combines a lightweight aluminium alloy body with precision-fit OFC/OCC connectors and solder-free construction.
• OCC Copper - OCC (Ohno Continuous Casting) process was developed by Professor Ohno, from the Chiba Institute of Technology, to manufacture a very high purity single grain copper or silver. There are only a handful of companies in the world manufacturing via this method.
• Microporous PTFE - Microporous PTFE (Teflon) is a unique, low density dielectric material, phase stable at room temperature, which offers significant performance improvements over solid PTFE (Teflon) dielectric designs.
• 4-Core + Screen Construction - Individually matched conductors (one pair for signal path, the other pair acts as the return conductor) enclosed within a protective woven screen. Combined with the dual-drain system which avoids distortion of the screening braid during assembly, which can change the RF impedance of the cable and adversely affect performance.
