AudioQuest “S” video cables include two identical maximum performance
coaxial cables, one for the “Y” (black and white) signal and one for the “C” (color information) signal. In single-channel “composite” video, the Y and C signals are combined to run on a single cable. Using S-video avoids the degradation caused by the process of combining and separating the Y and C signals. When available, three-channel Component video (AQ YIQ cables) is better because the Pb and Pr color information is not combined into a single C signal.
SOLID 1.25% SILVER CONDUCTORS: Solid conductors eliminate inter-strand distortion and reduce jitter. Solid silver-plated conductors are excellent for high frequency applications, such as S-Video’s 4.43MHz signal. These signals, being such a high frequency travel almost exclusively on the surface of the conductor. As the surface is made of high purity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. This is an incredibly cost effective way of manufacturing very high quality 75Ω cables. In order to achieve the best sound all digital audio conductors are controlled for directionality.
NITROGEN-INJECTED HARD-CELL FOAM INSULATION: Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation, circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Nitrogen-Injected Hard-Cell Foam insulation ensures critical signal-pair geometry while minimizing insulation induced phase distortion.
SHIELD COVERAGE (FOIL and 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 return path as well. Because of this, AudioQuest pays special attention to the shield’s metal quality and the fabrication technique as this will effect both the sound and the picture.
