SOLID 10% SILVER CONDUCTORS FOR IMPROVED SUBWOOFER PERFORMANCE Solid 10% Silver-Plated Copper Conductors: A superbly cost-effective way to maximize a video or digital cable, harsh and horrible for full-range audio, but like turning up the “sharpness” for a subwoofer, enhancing articulation and intelligibility. FEP AIR-TUBE INSULATION (FEP IS A FLUORO-POLYMER) Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then later released as distortion. Air, however, absorbs next to no energy, and FEP is the best extrudable solid insulation, absorbing less energy than other materials. The use of FEP Air-Tube insulation, with almost nothing but air around the solid PSC+ conductors, improves the sound of an audio system's focus and dynamics. TRIPLE-BALANCED GEOMETRY (SEPARATE GROUND-REFERENCE CONDUCTOR) Our Triple-Balanced Geometry uses a separate ground-reference conductor, so the cable's shield is never used as an inferior conductor. Whether prepared with RCA or XLR plugs, the cable's three conductors ensure that the positive and negative signals have equally superior, low-distortion conducting paths. DIELECTRIC-BIAS SYSTEM WITH RADIO FREQUENCY TRAP All insulation between two or more conductors is also a dielectric whose properties will affect the integrity of the signal. When the dielectric is unbiased, dielectric-involvement (absorption and non-linear release of energy) causes different amounts of time delay (phase shift) for different frequencies and energy levels, which is a real problem for very time-sensitive multi-octave audio. The inclusion of an RF Trap (developed for AudioQuest’s Niagara Series of power products), ensures that radio frequency noise will not be induced into the signal conductors from the DBS field elements. (DBS, US Pat #s 7,126,055 & 7,872,195 B1) CARBON-BASED 4-LAYER NOISE-DISSIPATION SYSTEM It's easy to accomplish 100% shield coverage. Preventing captured Radio Frequency Interference (RFI) from modulating the equipment's ground reference requires AQ's Noise-Dissipation System (NDS). Traditional shield systems typically absorb and then drain noise/RF energy to component ground, modulating and distorting the critical "reference" ground plane, which in turn causes a distortion of the signal. NDS's alternating layers of metal and carbon-loaded synthetics "shield the shield," absorbing and reflecting most of this noise/RF energy before it reaches the layer attached to ground.
