Design
ATL’s design of connectors significantly increases the buckle of safety and durability of the connector and lets the connector blade to be closely integrated with the copper wire.
For the Power Plugs and IEC connectors, ATL has developed a special wire buckle design that allows the bare wire to fit snugly to the contact surface and be tightly pressed by a non‐magnetic screw. ATL female clip, designed with the strength of force on both sides, reinforced the steel strength of pure copper clip with increasing contact area by 30% of the front surface. Because of enlarged areas of contact, the current/frequency 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 for contacts
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 Plugs, IEC Connectors, Receptacles, and C7 Connectors 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.
