Specifications

For maximum performance of your ETP pure copper product, prior to use allow longer burn-in time.

ETP Pure Copper

ATL Power company uses custom‐made ETP pure copper (Electro Tough‐Pitch), also known as cathode electrolytic copper. This copper, purity of which is 99.99%, has conductivity of not less than 100% of IACS (SGS certified) and nearly zero current loss at its transmission. Most manufacturers use brass or phosphor bronze for the production of power connectors, whose electrical conductivity is very low. Brass has only 25‐30%, and phosphor bronze — about 13%.

Due to the very high conductivity of ETP copper, we have very low contact resistance, thanks to which the current flows smoothly and results in a dramatic improvement in sound performance on a power system. It gives a big advantage to ATL connectors in comparison with other brands!

ETP copper is also highly plastic and resilient. This copper has excellent electrical and heat conductivity, good anti‐corrosion, weatherproof properties, and also sufficient hardness for use in power connectors, thanks to special ATL treatment.

Plating Technology

Except for products from pure ETP copper without covering, ATL Power manufactures connectors with two types of plating: gold plating and unique non‐magnetic multi‐layer plating.

Thanks to years of research and listening tests ATL Power has developed the non‐magnetic, multi‐layer (Cu‐Ag‐Au‐Rh) plating that creates a wide and deep sound stage, big sound images, great and articulated bass, and details are expressed perfectly.

• Cu (Pure Copper)
  Makes the performance of all frequency range smooth, solid, and natural
• Ag (Silver Plating)
  Strengthens the performance of high‐frequency range, making the sound of ETP copper more open and detailed
• Au (Gold Plating)
  Softens the full‐range frequency, making the sound of ETP copper with silver plating more mellow and plastic
• Rh (Rhodium Plating)
  Strengthens the whole range of extremely high frequency to create an overall sense of space and air and to demonstrate an unprecedented performance

ATL is using Pure Rh plating, which is whiter, compared to other brands’ Rh plating.

The arrangement of each plating layer, electroplating composition, and plating thickness all contribute to different sound characteristics, which harmoniously combine together and raise the sound quality of the connectors to a new Hi‐level.

This is the ATL’s key of know‐how.
