AudioQuest Diamond Digital AES/EBU XLR Cable
AES/EBU, developed jointly by the Audio Engineering Society and the European Broadcast Union, established a two-channel digital standard for interconnecting digital devices in the professional world. But, AES/EBU also has its application in the domestic environment as well. While AES/EBU can be single-ended, balanced, or optical, here refers to the balanced-digital interconnect.
Solid 100% Perfect-Surface Silver (PSS) Conductors
Perfect-Surface Technology applied to extreme-purity silver provides
unprecedented clarity and dynamic contrast. Solid conductors prevent
strand interaction, a major source of cable distortion. Extremely
high-purity Perfect-Surface Silver minimizes distortion caused by the
grain boundaries which exist within any metal conductor, nearly
eliminating harshness and greatly increasing clarity compared to OFHC,
OCC, 8N and other coppers.
Hard-Cell Foam Insulation
Hard-Cell Foam insulation is used exclusively in most of AudioQuest's
video and digital audio cables. Similar to Foamed-PE, it is nitrogen
injected to create air pockets. ‘Hard' foam is used because the
stiffness of the material allows the conductors in the cable to maintain
the same relationship with each other along the full length of the
cable, thus ensuring that the characteristic impedance of the cable is
consistent.
100% Shield Coverage (Foil + Silver-Plated Braid)
Shielding always plays an important role in any cable design, but the
shield on coax interconnect plays an especially important role because
it functions not only as a shield but a return path as well. Because of
this, AudioQuest pays special attention to the shield's metal quality
and the fabrication techniques as both will affect the sound and the
picture.
Dielectric-Bias System (DBS) All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down parts of the signal differently, a big problem for very time-sensitive multi-octave audio. AudioQuest's DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.
Carbon-Based 6-Layer Noise-Dissipation System (NDS)
100% shield coverage is easy. Preventing captured RF Interference from
modulating the equipment's ground reference requires AQ's
Noise-Dissipation System. Metal and Carbon-Loaded synthetics prevent
most RFI from reaching the equipment's ground plane.
