AES/EBU, developed jointly by the Audio Engineering Societyand the European Broadcast Union, established a two-channel digital standardfor interconnecting digital devices in the professional world. But, AES/EBUalso has its application in the domestic environment as well. While AES/EBU canbe single-ended, balanced, or optical, here we refer to the balanced-digitalinterconnect. SOLID 100% PERFECT-SURFACE SILVER (PSS) CONDUCTORS:Perfect-Surface Technology applied to extreme-purity silver providesunprecedented clarity and dynamic contrast. Solid conductors prevent strandinteraction, a major source of cable distortion. Extremely high-purityPerfect-Surface Silver minimizes distortion caused by the grain boundaries thatexist within any metal conductor, nearly eliminating harshness and greatlyincreasing clarity compared to OFHC, OCC, 8N and other coppers. HARD-CELL FOAM INSULATION: Hard-Cell Foam insulation is usedexclusively in most of AudioQuest’s video and digital audio cables. Similar toFoamed-PE, it is nitrogen injected to create air pockets. ‘Hard’ foam is usedbecause the stiffness of the material allows the conductors in the cable tomaintain the same relationship with each other along the full length of thecable, thus ensuring that the characteristic impedance of the cable isconsistent. 100% SHIELD COVERAGE (FOIL + TINNED BRAID): Shielding alwaysplays an important role in any cable design, but the shield on coaxinterconnect plays an especially important role because it functions not onlyas a shield but a return path as well. Because of this, AudioQuest pays specialattention to the shield’s metal quality and the fabrication techniques as bothwill affect the sound and the picture. 72V DIELECTRIC-BIAS SYSTEM (DBS, US Pat #s 7,126, 055 &7,872, 195 B1): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, abig problem for very time-sensitive multi-octave audio. AudioQuest’s DBScreates a strong, stable electrostatic field which saturates and polarizes(organizes) the molecules of the insulation. This minimizes both energy storagein the insulation and the multiple nonlinear time-delays that occur. Soundappears from a surprisingly black background with unexpected detail and dynamiccontrast. The DBS battery packs will last for years. A test button and LEDallow for the occasional battery check. CARBON-BASED 7-LAYER NOISE-DISSIPATION SYSTEM (NDS): 100%shield coverage is easy. Preventing captured RF Interference from modulatingthe equipment’s ground reference requires AQ’s Noise-Dissipation System. Metaland Carbon-Loaded synthetics prevent most RFI from reaching the equipment’sground plane. TERMINATIONS: Cold-Welded, Hanging-Silver directly over pureRed Copper. ]]>
