VARIDIG

Varidig is our exclusive (patent pending) technology. Varidig is different from any other digital cable on the market because its porous Teflon® dielectric is thicker in the middle of the cable than it is at the ends. The picture below shows geometry of the AES/EBU Varidig: please note as the wires become smaller in diameter as they approach the end (the termination point); the twisting pitch also varies along the cable - which is a great help in reducing cable' internal resonances.

This specialized dielectric geometry eliminates impedance mismatch at the critical points (where the connectors are attached to the cable, i.e. between the inherently low-impedance RCA connectors, or still far from 110 Ohms XLRs, and the cable itself) which allows to achieve the correct characteristic impedance of the ENTIRE cable, including the connectors (75 Ohms for the S/PDIF version, and 110 Ohms for the AES/EBU) and thus greatly reduce signal reflections in the cable. This Varidig technology works equally well with S/PDIF and AES/EBU configurations. Please see our Technical Notes for more details on the Varidig design.

TERMINATIONS

The Varidig cables are available in S/PDIF (coax, 75 Ohms ) RCA-to-RCA, RCA to BNC, and BNC to RCA configurations, and balanced AES/EBU (110 Ohms, XLR-to-XLR) configurations;

The year 2000 through 2004 RCA Varidig cables were made with gray outer jacket and were terminated with German-made WBT 0147 RCA connectors, which are the smallest and lowest in mass RCAs form the WBT line.

The RCA connectors used for current production Varidig are Cardas GSMO (as shown on the photo): we found them to work (slightly) better in the digital domain than the WBT because the dielectric used in these Cardas connectors is Teflon® (which has lower dielectric constant than the dielectric used in the WBT 0147 connectors);

In 2006, in order to improve the Varidig cable even further, we developed our own locking connector for this cable, to offer as an option. This connector features hollow solid silver hollow center pin (crimp termination technique), machined Teflon® dielectric, and a hybrid (brass/carbon fiber) locking collar.

The standard XLR connectors used with the AES/EBU (balanced) Varidig are sourced from Neutrik. Since August, 2006, we offer our own, upgraded XLR connectors as an option: machined Teflon® dielectric and solid silver hollow pins.

SOUND

Because of the advantages of its design, the Varidig allows more digital information from the source to reach the destination undistorted, and it's audible: subjectively, reduced or eliminated reflections in a digital cable is perceived as more silent background, cleaner overall sound and better "focus" and "attack". In general, the more advanced and sophisticated equipment is used, the better result can be achieved using the Varidig cable.
