Clear Digital Cable AES/EBUSold individually. Cardas Clear Digital AES EBU employs a perfectly symmetrical tri axial geometry by using air tubes to separate and suspend our PTFE taped, Matched Propagation conductors. Additional air tubes are arranged outside the core of the cable to 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. Termination
