Cable capacitance plays a decisive role, especially for audio cable connections between individual devices. As the signal sources are very weak and react sensitively to high cable capacitance, audio cables are virtually predestined for air insulation using air helix technology.

In addition to this, we have also developed a completely new and entirely solder-free RCA connector for the Referenz NF-1205 Air. It consists of several component parts that are only joined together during the course of the assembly process. As with the loudspeaker cable, the thin layer of enamel is first removed from the high-purity copper wires of the "Cross Link Super Speed" waveguide by machine. Then, the contact pin of the connector, which is made of tellurium copper, is pressure-grouted with the conductor using a force of 1.5 tonnes. The connection of the shielding is also completely new: It is now hermetically sealed with screws.
