Coaxial architecture

Because the outputs on hi-fi devices only supply extremely weak signals and are sensitive to high cable capacitance, the capacitance of a cable plays a significant role when connecting components together. A “low-pass filter” can be created that cuts off high frequencies and also causes phase shifts. This is the reason why RCA and XLR audio cables are ideal companions for the air-based insulation used in the MICRO AIR technology. Another special feature of the NF-204 Micro AIR is its symmetrical architecture, which guarantees high immunity to EMC radiation. Alone or in combination with the LS-204/LS-204-XL, the NF-204 Micro AIR opens up the connection floodgates and allows your components to perform at their very best.

Micro AIR technology

We are not able to switch off the laws of nature, so the best we can do is use them as ingeniously as possible. Due to the laws of nature, every cable exerts so-called parasitic effects. These include capacitance – the capacity to store energy like a battery and release it again with a time delay. This effect has a considerable impact on the transmission of audio signals and is therefore unwelcome. Capacitance is a physical property, and its value depends on a number of different factors, one of the most important of which is the insulation material used, also known as the “dielectric”. The dielectric material can considerably increase the capacitance of the cable. Because air doesn’t do this, it’s ideal for insulation purposes. One of the insulation elements in the Micro AIR technology is a complex, diamond-shaped structure. The tiny chambers created by this structure increase the distance between the conductors and raise the air content of the insulation. This method reduces troublesome capacitance effects and optimizes the cable’s transmission characteristics for the sensitive audio signals it needs to transport.

Concentric copper

Unlike the sometimes chaotic arrangement of individual wires in conventional conductor designs, concentric copper conductors are arranged in a precisely defined multi-layer pattern. This design reduces irregular contact points between the wires, which harmonizes the signal flow and minimizes runtime differences. Impulses can be reproduced with pinpoint accuracy and the spatial information of the music is retained. A thin layer of polyethylene protects the high-purity copper from oxygen and thus from oxidation.

Copper is the best electrical conductor after silver under normal conditions. Compared to cheap CCA (Copper Coated Aluminum) in particular, copper has a significantly better conductivity and is also mechanically more resilient. The conductors of the Micro AIR cables are made of high-purity OFC (Oxygen Free Copper).
