Atlas Element (Basic) 1.25 Black Speaker Cable
The Atlas Element 1.25 Basic is well suited as an upgrade for high quality compact systems or for rear channel speakers in a 5.1 set-up. The Atlas Element 1.25 contains 1.25mm² of stranded OFC (Oxygen Free Copper) contained in a high density polyethylene dielectric (insulation layer), unusual at this price point where PVC is much more common. Low quality dielectrics such as PVC typically degrade the music signal by imposing a characteristic blurring on the sound.

- OFC Conductors
- PEF Dielectric
- Multi-Core Construction
Atlas Gold Plated Z Plugs
The Atlas Z plug has stood the test of time. Using beryllium copper for the contact area, It's designed to make a 100% contact within the 4mm female socket. The body is made from copper and it's available for home assembly with grub screws to make contact with the conductors. When factory fitted or fitted by an Atlas appointed custom cable centre, they're cold welded under pressure in order to amalgamate the conductors to the plug in an air tight seal. The outer sleeve is finished in black coloured ABS or in a turned brass with a fine oven applied powder coat finish. The Atlas Z plug is justifiably considered to be one of best 4mm plugs available.
- Low resistance
- High conductivity
- 80% copper with beryllium 4mm section giving 100% contact
- Corrosion resistant
- Accepts conductors up to 5mm diameter
- Solder free for a cold weld air tight interface between the plug and conductor or grub screw contact for DIY enthusiasts
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.

PEF 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).
HDPE (High Density Polyethylene) has a more close-packed structure compared to its more flexible cousin LDPE (Low Density PE) and excels in its durability.
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.
