ATL ETP‐700 series are the world’s first ETP copper‐made power inlets. With the excellent performance of the ETP‐700 series, your audio system will be totally different!
This product is made according to international standard IEC320 C20 size, provides for conveniently direct installation into most standard cut‐outs.
For maximum performance of your ETP pure copper product, prior to use allow longer burn-in time.
Design
All pins of ETP‐700 Power Inlets are made from one piece of ETP copper on precision CNC machines. The increased area of direct contact of the wire clamped inside the copper pin gives a very big advantage and is the biggest difference from other brands.
Because of enlarged areas of direct contact, the current has less resistance. It not only improves the power connector’s safety but also its performance in the sound. The audio system, therefore, gets the best results.
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.
Housing material
ATL Power Inlet housing is made of custom‐made A‐class flexibility and high impact/fire‐proof nylon material. It is not only for safety considerations in audio, but it is also helpful in terms of medium/low frequency performance. This is what ATL studied long‐term and made other materials through comparison and testing.
Different hardness of the material produces different sound. It was found that some harder materials make the sound more energetic, with the articulated bass, while softer materials influence on all range, making the sound more solid and smooth. All these features are balanced in ATL connectors.
Warning
ETP copper products are softer than brass due to their material characteristics.
Care must be taken to slowly wiggle brass screws into copper contacts and brute force should not be used for this. Please use a quality screwdriver T6 star‐type for this. It is very important that excessive force is not exerted onto the components.
