The collaboration between the Audio Engineering Society and the European Broadcast Union resulted in the development of AES/EBU, setting a two-channel digital standard for linking professional digital devices. However, AES/EBU also finds relevance in domestic settings. Although it offers various connectivity options such as single-ended, balanced, or optical, our focus here is on the balanced-digital interconnect.
SOLID PERFECT-SURFACE SILVER (PSS) CONDUCTORS
Solid conductors prevent electrical and magnetic strand-interaction. PSS Solid-Silver minimizes distortion caused by grain boundaries and maximizes linear RF Noise-Dissipation.
72v Dielectric-Bias System (DBS)
Insulation is also a dielectric that can act like a shunt-filter. Biasing minimizes dielectric-noise and linearizes the filter, significantly improving wide-bandwidth dissipation of induced RF noise.
CARBON-BASED 7-LAYER NOISE-DISSIPATION SYSTEM (NDS), 3 X EMI ABSORPTION
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.

HARD-CELL FOAM INSULATION
Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard-Cell Foam Insulation is similar to the Foamed-PE used in our more affordable Bridges & Falls cables, and is nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable’s conductors to maintain a stable relationship along the cable’s full length, producing a stable impedance character and further minimizing distortion.
