Cord Insulating & Damping System (CIDAS) was developed for the new mid-range Special power cord and speaker cable. BRC conductors and PVC cords of the same diameter are configured next nearest around a central PVC cord in a hexagonal structure 3+3+1 with maximum packing factor ensuring highest conformity and an exact round profile for perfect concentric dielectric binding and jacket overlaying. Interleaving cords are made of SPVC with enhanced dielectric properties and high mechanical decrement. CIDAS provides efficient conductor damping and drastically reduces electro-dynamic noise, caused by the conductor vibration and movement in the Earth’s magnetic field. The symmetrical spatial conductor straddling decreases cable distributed capacitance and ensures a more efficient energy transmission with a clearly audible dynamic range extension, sufficient gain in definition along the full frequency range and awesome transparency.
