• "Point-to-point Air Helix” for authentic sound.
• Air as the ultimate dielectric minimizes capacitance
• 4-fold multicore design reduces the line inductance
• Rhodium-plated ultra high-quality (UHQ) connectors

A hi-fi system basically reproduces nothing other than modulated household electricity. This means this should arrive at the device as constantly as possible. Here the mains cable (power cable) plays a significant role. The big challenge for power supply cables is extreme current peaks. They are caused by the connected devices themselves converting alternating current into direct current. These extreme current peaks cause a whole range of undesirable effects.

Specially designed for connecting up top-notch high-end audio systems, the Referenz AC-2405 AIR mains power cable is based on the already legendary AIR technology. In conjunction with this technology, i.e. the "omission" of insulation material, which would "soak up" part of the energy like a sponge, the Referenz AC-2405 AIR is able to transport very large amounts of energy in a very short time. Many design details of the Referenz AC-2405 AIR counteract the undesirable effects and make it an outstanding energy pipeline for the highest audiophile requirements.

However much we focus on high-end sound, safety plays a particularly important role in this cable category. For this reason, every Referenz AC-2405 AIR cable is tested extremely carefully. In addition to an exhaustive functional test, each cable is also subjected to an insulation and high-voltage test. The results are documented, and each cable is given an individual serial number.

Thanks to the Air Helix design, the conductors run freely suspended through the length of the cable.

The Air Helix architecture permits signal conductors to be insulated to practically 100% by air. Special clips were developed to provide the supporting framework. Positioned at defined intervals inside the cables, these clips keep the helically-arranged conductors apart. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from each other. This architecture is unique, bringing low capacitance and minimum dielectric losses – a true milestone in the search for open and unadulterated sound.

Our physical approach: Minimize losses for true-to-original playback.

Our Referenz AIR cables transport audio signals between source, amplifier and speaker in an authentic way and with a minimum of loss. You can enjoy music that precisely expresses the emotions of the artists at the time of recording – sensual, subtle, light-hearted or orchestral right through to full-blooded and rocking. Vocals and instruments are delivered in unadulterated form. Everything remains vibrant and full of emotive energy. Favorite tracks and pieces continue to trigger strong feelings even when you’ve heard them a hundred time over.

To the point

AIR-Helix

The Air Helix architecture enables the signal conductors to run freely suspended through the length of the cable and permits signal conductors to be insulated to practically 100% by air.

The dielectric

Using air as a dielectric lowers capacitance to a minimum. In comparison with other insulators, using air as a dielectric leads to no increase in capacitance and creates no dielectric losses.

Multicore structure

By cleverly arranging the conductors in the multiply nested multicore structures, overlapping magnetic field areas are created that significantly reduce inductance.

Safety first

In addition to an exhaustive functional test, each cable is also subjected to an insulation and high-voltage test. The results are documented, and each cable is given an individual serial number.

The challenge

The challenge for power cables are extreme current peaks that can generate strong magnetic fields and interference radiation and therefore lead to power losses. These rapidly changing increases and decreases in current must be passed on to the electronic components with as little delay as possible, since a blocked current flow would have a negative effect on the sound.

Point-to-point Air Helix for end-to-end connections

A new feature in the 5th generation of in-akustik’s Air Helix architecture is the point-to-point connection. Specially designed transitions are available for each type of cable and connector. Across the complete length of the cable – point-to-point AIR Helix. It may sound trivial at first, but the results are impressive. Sound signals are transported with minimized losses, right through to the final centimeters. The sound is more detailed and dynamic than even before.

Multicore

The multicore structure leads to an overlap, so compensating for the magnetic fields around the individual cores. This greatly or extremely minimizes the line inductance, depending on the number of cores. In addition, the higher number of individual cores significantly reduces the skin effect caused by steep current flanks at high frequencies. The division into several cores also increases the usable conductor cross-section without the negative effects of thicker cables.

Safety

Safety is of the utmost priority to us: However much we focus on high-end sound, safety plays a particularly important role in this cable category. That‘s why every Referenz AIR power cable is tested and inspected extremely carefully. In addition to an exhaustive functional test, each cable is also subjected to an insulation and high-voltage test. The result is recorded and each cable is given an individual serial number; each cable is also certified and complies with and is of course CE-compliant.

Shielding

Unlike most other power cables, the in-akustik Referenz AIR cables are encased in a dense shielding braid of tinned copper. This protects the hi-fi system from external interference and any nearby cables and audio components from radiating interference fields caused by the high current peaks in the cable. The tinning of the braid also prevents any oxidation of the cable.

Cable manufacturing unit

The beating heart of in-akustik is our manufactory. This is where our success story is rooted – permeated by a congenial working atmosphere, a love of music and a passion for detail. At in-akustik, we believe musical enjoyment stems from a listening experience that remains as close as possible to the original recording and the artist’s interpretation of the piece. That’s why we boast a committed workforce that combines curiosity with a keen sense of precision. With a fascination for music and things that are really special – like the development of our complex AIR cables.

Background

A hi-fi system basically reproduces nothing other than modulated household electricity. Ideally, this should be made available to the components without any further inhibition. However, dynamic music with complex bass runs places an impulsive load on the electronics of the integrated or power amplifiers belonging to a high-end hi-fi system. Here the power cable plays a significant role. The challenge for power cables on audio devices with a high sound quality are extreme current peaks that can generate strong magnetic fields and interference radiation, leading to power losses at line and transition resistances.

These rapidly changing increases and decreases in current must be passed on to the electronic components with as little delay as possible, since a blocked current flow would have a negative effect on the sound. Physics tells us that an electrical conductor has capacitive and inductive characteristics in addition to its resistance, and these disturb the flow of energy between the power socket and the hi-fi device. The goal is always a power supply without any time-lag and with minimum loss, enabling large amounts of energy to be transported in a very short time. Accordingly, the power cable from the wall socket to the hi-fi equipment plays a very important role in the transmission chain.

Perfect sound for audiophiles: Specially designed for connecting up top-notch high-end audio systems, the Referenz AIR power supply cables are based on the already legendary in-akustik AIR technology. Their many special features effectively counteract the undesirable effects encountered while supplying power to high-performance audio components and make supply cables what they should ideally be: superb energy pipelines for perfect high-end sound.
