Digital Audio Cable

AudioQuest Digital Coax cables are designed to minimize distortion across an extremely wide bandwidth. For many applications, the speed of digital communication is important. Most visibly, “speed” is about transferring large files as quickly as possible, or carrying enough data for HD video.

For Digital Coax audio “speed” is critical not because of how-much how-fast, but because time relationships within a digital stream are critical to the reconstruction of the analog waveform that brings information, music and joy to our ears. Time-based damage (jitter) to this information within the data package makes the sound small and flat instead of 3D, harsh and foggy instead of smooth and clear.

DESCRIPTION

Solid 10% Silver Conductors
Solid conductors minimize the harmful effects of both electrical and magnetic strand-to-strand interaction. For digital cables, whose signals are of such high frequency that they travel almost exclusively on the surface of the conductor, increasingly thick layers of silver plating are applied to AudioQuest’s Long-Grain Copper (LGC) conductors to further improve Noise-Dissipation. Placing the superior metal on the outside of the conductor produces the greatest benefit on overall performance—a superbly cost-effective way to maximize a digital cable.

Carbon-Based 5-Layer Noise-Dissipation
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.

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.

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.

Key Features & Technology Explained

Solid Conductors

Solid conductors prevent strand-interaction, a major source of dynamic distortion in cables.

Metal

10% Silver-Plating is applied to AudioQuest's Long-Grain Copper (LGC) conductors to improve noise-dissipation.

Noise Dissipation

Alternating layers of metal and carbon-loaded synthetics "shield the shield", absorbing and reflection most RF energy before it reaches the layer attached to ground.

Technology

72v Dielectric-Bias System (DBS) saturates and polarises insulation, allowing clear, dynamci sound against a quiet "black" background.

Insulation

Hard-Cell Foam's high air content minimises energy absoprtion for clearer sound.
