It’s long been known that the quality of mains power can have a dramatic effect on the performance of hifi & home cinema systems. A clean, quality power supply requires cables resistant to external interference and noise on the mains itself. The Eos 4dd Power Cable uses OFC 4mm² conductors in an aluminium foil screened configuration with Atlas' DD (dual drain) system and their precision-engineered mains plug. The 4dd is specifically designed for ‘high-end’ systems and high power devices.
Power management is required principally as a result of the increasingly negative impact of electical, radio frequency and electromagnetic noise pollution flooding our homes and daily life. With increasing use of high resolution audio and video content our replay equipment has come under assault by extraneous high energy broad spectrum noise, both airborne and directly induced through the mains supply circuits. Wi-fi networks, BlueTooth devices, mobile & domestic cordless phones, ‘wallwart’ power adapters, low voltage light bulbs & dimmer switches are among the worst noise-generating culprits.
Eos power cables are sophisticated products designed specifically to allow your equipment to perform properly. Built around high purity low resistance OFC (Oxygen Free Copper), with low series resistance, high-efficiency dielectrics and extensive screening, Eos 4dd cables effectively filter out harmful incoming radio frequency and power contamination, dumping these rapidly to earth. By comparison a typical domestic power lead in comparison, lacks the quality of component parts, screening layers, dual drain system and anti-vibration treatment Atlas' employ in Eos.
For maximum effectiveness, Eos cables are best used as part of a complete Power Management System.
Precision-machined Atlas-designed mains connectors with silver/rhodium-plated pins for low contact resistance. Available in UK (13A Silver), Schuko & Nema versions depending on country of original supply.
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.

Normally screened cables suffer from screen distortion when they are prepared for production. (If you've ever wired a plug or connector which uses a screened cable, you've done this yourself, cutting back and probably twisting the screening braid for termination). This distortion of the screen has a measurable impact, effectively changing the impedance and therefore the performance of the cable.
Atlas' ‘dd’ configuration is based on a simplified version of the techniques they developed for their top-of-the-range Mavros and Asimi interconnects. Twin symmetrical drain wires (each attached to 180° segments of the plug) are inserted between a 100% copper/Mylar™ foil and screen. The unique dd system connects the screen effectively to the cable return/plug interface, meaning the cable can be terminated without distorting, twisting or mechanically stressing the precision-laid screen. The benefits are in maintaining a consistent low impedance load to the plug, and a total 360° screening against noise and signal loss caused by RFI (Radio Frequency Interference).
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).
PTFE (Teflon™) is usually applied at higher temperatures and in combination with OFC conductors. OCC materials don’t like high temperatures (soldering, applying the dielectric etc) so application of a low temperature PTFE (Teflon™) or FEP work best with OCC conductors. This is especially critical at smaller conductor sizes.
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.

A pair of identically matched conductors (one for signal path, the other acts as the return conductor) enclosed within a non-conducting screen.
To ensure the best possible connection between your system, Future Shop recommends the DeoxIT Gold G-Series contact enhancer.
DeoxIT Gold is carefully applied to the plug contacts of your cable and is a unique conditioning solution designed to improve conductivity and provide long-lasting protection on gold, base metals and other precious metal contacts and connections. DeoxIT Gold penetrates plated surfaces, molecularly bonding to the base metals to seal and protect both surfaces.
The benefits of applying DeoxIT gold are:
Please select this option from the above ‘Contact Enhancer’ drop-down menu and our engineers will apply the contact solution to your cable connectors prior to shipping.
Atlas Cables are a major producer of interconnects and cables in the United Kingdom of Great Britain. All products are researched, developed and most are assembled in the Atlas purpose built factory in Scotland.
