Atlas Element Series 1.0 m XLR Cables

Regular price $230.00

Based on Atlas' multi-award winning Element Integra interconnect, the Element XLR utilises a shielded four-core construction providing excellent immunity to interference and noise, making it ideally suited to longer cable runs.

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 is 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.

Atlas XLR Plug

The Atlas XLR combines a lightweight aluminium alloy body with precision-fit OFC/OCC connectors and solder-free construction.

Atlas XLR Plug Technical Diagram

Oxygen Free Copper (OFC)

OFC is produced through an extrusion process which takes place in an oxygen-free-inert-gas atmosphere. This leads to a reduced oxygen content (10 ppm) when compared to Tough Pitch Copper (TPC) and an improvement in conductivity which typically measures in at between 0.5% and 2% greater than TPC. The OFC process therefore produces a much higher quality audio cable than the TPC process. High purity conductors sound clearer than their unprocessed (TPC) counterparts because there are fewer crystal boundaries present to cause signal degradation.

XLPE Dielectric

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.
