LightSpeed Pure Energy technology
All LightSpeed power cord includes a special Pure Energy electronics that can effectively filter DC components that contaminate the alternating current. This results in cleaner sinusoidal alternating current, which results in more efficient operation. The special of LightSpeed Pure Energy electronics is the lighting rings of the connectors that provide a unique look to Signature 4D power cords.
LightSpeed Signature 4D has Balanced quad dual-core structure conductors, 6 AWG total conductive cross-section, separated multi-purpose shielding, and reduced resistance. The appearance of the Ultimate 4D model has the newest 4D braid structure, which ensures symmetrical a transverse positioning, thereby minimizing the inductive and capacitive effects of the parallel construction of the conductors, which negatively affect the alternating current phase accuracy.
The increased cross-section Balanced quad dual-core conductors are covered with special anti-static film, tin-plated, dense woven pure copper shielding, synthetic polymer insulation, and a special high-density polyester damping outer casing. The high-density polyester layer has a dielectric constant lower than the often used Teflon insulation and provides adequate protection against vibrations from the environment
LightSpeed Signature 4D has Balanced quad dual-core structure conductors and 9 AWG total conductive cross-section, providing balanced and continuous power to the connected devices. The advantage of the Balanced quad Penta-core design is the symmetry, as all wires have the same cross-section and electrical parameters, providing balanced, continuous, and stable performance as opposed to asymmetric cables. The asymmetric cables, such as those with double-phase conductors, can cause continuous fluctuations in alternating current due to different cross-sections and electrical parameters. Even the slightest fluctuations in the power supply can affect the stable operation of audio and video devices, as it can cause continuous noises in the sound and picture.
In addition to the advantages of symmetric design, the Balanced quad dual-core structure effectively reduces the skin effect, as conductors are not only composed of elementary strands but are arranged in separate groups. The cross-sectional of the multi-core conductors small enough to prevent the skin effect from developing, but overall, the conductors have an adequate cross-section to provide optimal power supply.
The LightSpeed Signature 4D model received high-quality, hand-selected polymer-composite connectors with pure copper contacts inside. The rhodium-silver coating on the outside of the contacts provides the right connection, which has measurably better electrical parameters than for example gold coating and is more resistant to environmental impacts.
In addition to the high quality of the connectors, the special look is also emphasized by the built-in LED lighting. The lighting rings of the connectors give the Signature 4D model a unique look.
Signature 4D power cords are built with solder-free, precision hand assembly.
Technical characteristics: Resistance: 0.0014 Ω/ft, Capacity: 10 pF/ft, Inductance: 0.1 μH/ft
LightSpeed Signature 4D power cords are available with US or EU plugs and special EU/UK adapter.
Available lengths: 4 ft / 120 cm and custom sizes.
NOTE: To get the best quality of LightSpeed power cables, it needs a “burn-in” period. After about 10-14 days of using LightSpeed cables, the sound quality becomes more life-like.
