Description

Atlas Element Mezzo 2 XLR to 2 XLR Audio Cable - Pair

 

Based on Atlas' highly regarded Element XLR interconnects, the Element Mezzo XLR has been designed to meet the increasingly popular requirement for a cost-effective balanced cable with very little compromise in performance. The actual cable itself is identical, but the Mezzo uses a copper alloy body and pins as opposed to the high-purity OFC pins and aluminium alloy-bodied plug of the Element XLR.

 

Features

  • Copper-Alloy XLR
  • OFC Conductors
  • PEF Dielectric
  • 4 Core + Screen Construction

 

Copper-Alloy XLR

The Mezzo XLR combines a copper-alloy bodied plug with copper-alloy connectors and crimped (solder-free) construction.

 

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.

Polyethylene (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). PEF (Foamed Polyethylene). The foaming process uses a blowing agent, of which there are two types. Atlas use the gas-foamed method which creates a more inert, consistent and higher quality product. 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.
