AudioQuest VDM Series cables are designed to minimize distortion across an extremely wide bandwidth. A 75ohm cable is like a conduit that has to carry relatively low-frequency analog video (composite video, up to 4.2 MHz), or super-sensitive digital audio (S/PDIF, up to 24.576 MHz), or uncompressed High-Definition video (up to 750 MHz), or cable TV/broadband (CATV, up to 1 GHz). AQ VDM (pre-terminated cables) and VSD (bulk installation cables) cables are designed to carry all these signals with minimum interference.
Solid 1.25% Silver Conductors:
Solid conductors eliminate strand-interaction distortion and reduce jitter. Solid silver-plated copper conductors are excellent for very high-frequency applications, such as digital-video signals. 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 75ohm cables. In order to achieve the best sound all digital-audio conductors are controlled for directionality.
Hard-Cell Foam Insulation:
Hard-Cell Foam insulation is used exclusively in most of AudioQuests 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 shields metal quality and the fabrication techniques as both will affect the sound and the picture.
VDM-X is available with RCA connectors.
