Cardas Clear AES/EBU Digital Interconnect
Tri-axial geometry with air tubes and Matched Propagation conductors.
Cardas's Clear Digital AES/EBU uses air tubes to separate and suspend the PTFE-taped, Matched Propagation conductors in perfectly symmetrical tri-axial geometry. Additional air tubes outside the core place the braided shield in the perfect position. Additional shielding is provided by a carbon-impregnated semi-conductive PTFE tape which works with the shield to dissipate noise.
The Clear line is based on learnings and technology from the Clear interconnect which was made possible by George Cardas’ invention of the Matched Propagation Conductor in 2010. These conductors, with both speaker and interconnect variants, match the propagation velocity of the signal through the copper wire to the propagation rate of the best available dielectric materials.
The telephone industry has long understood and accepted the garbling that occurs when the signal outpaces the dielectric. It is fitting that long before founding Cardas Audio, George Cardas spent years as a line engineer with the telephone company in Southern California.
The Matched Propagation Solution prevents distortion by matching the propagation of the conductor to the dielectric through the use of specific pitch angles for each strand of copper wire wrapped around a core of Kevlar yarn. A selection of hard-to-obtain, high-performance dielectric materials with fast dissipation rates ensures that the signal remains intact and intelligible throughout the length of the cable.
The result is a conductor that conveys an unprecedented level of realism and transparency, without any detriment to the musicality of the system.
