With this ground-breaking technology, which is the foundation of our top-end Reference & Ultimate cables, we prove vibration damping is a crucial parameter. Cable-Core consists of two insulated BRC conductors twisted symmetrically with two filling cotton cords of a bigger diameter and tightened with the dielectric binding under a consistent pressure. Named FTDA® (Fiber Torsion Damping, patent RU No.124834U), this method is based on a principle of a conductor free floating in a viscous longitudinal fibre surround with high mechanical decrement.
FTDA® provides efficient conductor damping and drastically decreases electro-dynamic noise, caused by a conductor’s vibration and movement in the Earth’s magnetic field. To ensure a sufficiently high decremental ratio, the cotton fiber was chosen as a damping material because of its high longitudinal strength and filling ability. Moreover, a high percentage of air inside and between cotton fibers decreases relative permeability and signal energy loss. High inter-fiber torsion and low filler density enhances absorption of mechanical vibrations affecting a cable throughout the entire frequency spectrum by as much as 50 times and ensures the widest attainable dynamic range, which in this case is mainly limited by thermal noise and thermoelectric contact potentials.
