Atlas Mavros 2 XLR to 2 XLR 1.5m
XLR interconnect cable based on the same design objectives and manufacturing techniques developed for Atlas’ Asimi range, utilising copper rather than silver conductors. The Mavros XLR is a superb interconnect designed to complement the performance of ‘high-end’ audio systems by achieving maximum signal transfer.
The Mavros XLR uses the very highest quality ‘6N’ (99.99997% purity) copper manufactured using the OCC ‘Ohno Continuous Cast’ technique. Cables manufactured with lower grade materials and poor manufacture typically have a coarse, grainy structure which compromises sound quality. In the manufacture of Mavros, Atlas maximise the copper’s conductivity by ensuring that there is typically one grain in approximately 125 metres of conductor, allowing the signal a continuous unbroken path –in practice, the signal has a faster, cleaner and more direct path to follow.
The cable consists of a pair of conductors, each made up from six bundles of 12 multi-conductor wires, plus a thicker centre wire. This in turn is covered by a continuous copper/Mylar™ electrostatic screen with copper shielding braid, ensuring minimal susceptibility to RF interference and noise.
Theoretically, the best dielectric (insulation layer) is air. Conventional dielectric (insulation) materials impose their own signature distortion and loss on the signal. Atlas’ technique uses a microporous PTFE (Teflon™) tape, which is wound around the core conductors, then covered again and stabilised using a protective FPE (Flexible PolyEthylene) dielectric. This process maintains the required conductor geometry, and bestows greater manufacturing consistency.
Atlas use cold-weld terminations wherever possible, including their current generation ‘dark Chrome’ XLR connectors. By reducing the number of materials and break points in the signal path, Atlas’ objective its to minimise discontinuity and loss in the signal path, resulting in more consistent construction and improved audio performance.
Atlas XLR plugs are wired as follows by default: Pin 1 = Ground; Pin 2 = Hot, Pin 3 = Cold. If you require a different configuration, please contact us.

The Atlas XLR combines a lightweight aluminium alloy body with precision-fit OFC/OCC connectors and solder-free construction.
Ohno Continuous Casting Copper (OCC Copper)
The Ohno continuous casting method re-heats the extrusion as the molten copper is forced out of the mould and very slowly and gradually draws the grain or crystal down the conductor”s length, creating a ‘single crystal structure.’ Actually, because no copper is 100% pure, there will always be a few boundaries produced by impurities. The frequency of boundaries created are quite insignificant. A typical crystal in a copper conductor drawn to 0.3 mm diam. using the OCC process is 125.00 metres long!
The benefits are obvious, with almost no crystal boundaries, the audio signal is no longer impeded down the copper wire and more information and detail is delivered faithfully to the receiving equipment.

PVC (Poly Vinyl Chloride) is cheap to produce and, as such, is the most commonly used insulation in AV cables. However, PVC is the worst quality insulation a Hi-Fi or AV signal can encounter as its high loss causes a significant reduction in signal velocity. PVC is better suited to power cables and should be avoided in Hi-Fi and AV signal cables.
Other dielectrics in common use are Polyethylene, Polypropylene and Polytetrafluoride Epoxy (better known as PTFE (Teflon™) or Teflon,) and the new and unique Atlas (PTFE).
XLPE Dialectric is a form of LDPE (Low Density Polypropylene) formed with cross-link polymers, stable and used extensively on medium voltage cables.
The table below shows the properties of a selection of dielectrics. Though not used as a dielectric in Atlas’ cables, PVC is included for comparison purposes.

Atlas Cables are a major producer of interconnects and cables in the United Kingdom. All products are researched, developed and most are assembled in the Atlas purpose built factory in Scotland.
Many of these products are unique and use advanced techniques of production or manufacture in order to bring to the user the very finest quality products. With each new model we continue to push the boundaries of reliability and performance. It’s little wonder then, that Atlas Cables have had so many mile-stone advances in the past and that Atlas Cables have secured so many awards in comparative tests against other products.
