Soundscapes are created by the dynamics in the music. To exploit the full potential of your high-end audio components, you need a reliable power pipeline that provides your components with the power peaks with as little delay and loss as possible. This is where the AC-1205 AIR mains connection cable comes into play. Our innovative AIR technology has already caused a sensation in the high-end scene and now also forms the architectural basis for the AC-1205 AIR mains cable. Using specially developed clips, the individual conductors are held at fixed distances and insulated from each other by an "air dielectric". This reduces both capacitive and inductive interference and ensures a smooth flow of energy. The multicore design of the AC-1205 AIR neutralizes the magnetic interference and magnetic fields generated by current peaks and minimizes the line inductance. In addition, the large number of individual wires reduces the skin effect that occurs at high frequencies. Splitting the current across many cores not only increases the usable conductor cross-section, but also increases the overall cross-section of the cable. The result is a reliable power supply, even in the most demanding passages, which allows your sound system to develop its full potential. To minimize electromagnetic interference fields, the AIR cables are shielded with a dense braid of tinned copper. This not only protects your audio components, but also neighboring cables from unwanted interference caused by the high current peaks in the power cable. The in-akustik High End AC-1205 AIR mains cable is an outstanding energy pipeline for perfect audiophile sounds. It eliminates unwanted effects and makes a not insignificant contribution to the most authentic music reproduction possible. Click here and discover the exciting details

The CAT-2405 AIR is a high-end LAN cable designed for connecting audio components in streaming setups. It is based on our specially developed Air Helix construction, which enables low-loss and interference-resistant signal transmission. For this construction, we have designed a special clip that forms a stable supporting framework inside the cable. Several of these clips hold the signal pairs in a helical shape and at a defined distance freely in the air. The entire arrangement runs within a high-density shield. Two connecting bridges keep the clips evenly spaced and at the same time provide the necessary flexibility in the cable structure. Digital signal transmission: In mathematics, digital information is represented as binary values, but technically it is transmitted via analog voltage curves. To distinguish between states such as "0" and "1", voltage thresholds and time windows are defined. The transition between these states does not occur abruptly, but continuously—the signal passes through intermediate values, for example, between 0 and 5 volts. Capacitive loads, dielectric losses, noise, and external electromagnetic influences can distort these transitions. This results in timing shifts in the signal, known as jitter. Jitter makes it harder to assign data precisely in time and impairs the reconstruction of digital audio signals. Advantages of the Air Helix construction: The overall shielding made of dense braid, as well as additional foil shields for each pair of wires, effectively protect against external interference. The Air Helix construction uses air as a dielectric and ensures a constant distance between the wire pairs. This arrangement reduces crosstalk and capacitive losses, contributing to unadulterated signal transmission. Streaming components and integrated digital-to-analog converters (DACs) benefit from the improved signal quality and can process data more precisely. CAT connector with rotation mechanism: Conventional RJ45 connectors can only be plugged in at a fixed orientation. Depending on the position of the socket, this can result in unfavorable cable routing and mechanical stress on the connector, cable, and socket. To counteract this, we use rotatable RJ45 connectors with a 180° mechanism. Each connector can be rotated by about ±45°, resulting in a total adjustability of about ±90° between both connectors. This allows the cable to be routed without tension and in a space-saving manner. Sound Advantages at a Glance: Air Helix construction: Signal pairs arranged helically in air—minimal capacitive losses Air as dielectric: Reduces crosstalk and improves signal purity High-density shielding (tinned): Overall and pair shielding against electromagnetic interference RJ45 connector with 180° rotation mechanism: Flexible, tension-free cable routing Optimized for high-end streaming: Supports precise clocking in digital audio transmission Conductor material: High-purity OFC copper for stable, low-loss transmission Technical specification: CAT 8.1—up to 2000 MHz bandwidth Made in Germany: Development, manufacturing, and quality assurance on site Click here to discover exciting details
Die Air-Helix-Konstruktion des Referenz USB-2405 AIR ist absolut einzigartig. Um eine nahezu perfekte Luftisolation zu erreichen, haben wir einen speziellen Clip entwickelt. Im Innern des Kabels bildet eine Vielzahl dieser Clips ein tragendes Gerüst, welches die Signalleiter helixförmig frei in der Luft hält und in definiertem Abstand durch die hochdichte Abschirmung führt. Die Flexibilität dieser Konstruktion wird durch zwei Stege erreicht, die nicht nur die Clips zusammenhalten, sondern sie auch auf dem exakten Abstand zueinander fixieren. Im eigentlichen Sinne ist „Digital“ nur in der Mathematik in Form des dualen Zahlensystems vorhanden. In der technischen Welt existieren keine reinen digitalen Signale. Zur Detektion von Nullen und Einsen werden elektrische Spannungsgrenzen und Zeitfenster definiert. Der Sprung von einer Null zu einer Eins oder umgekehrt erfordert immer eine gewisse Zeit, in der der Signalpegel alle Zwischenwerte, beispielsweise von 0 Volt bis 5 Volt, durchläuft. Kapazitive Lasten, dielektrische Verluste, Rauschen und elektromagnetische Störungen, die durch Kabel verursacht werden, manipulieren diesen Übergang zusätzlich. Das resultiert in zeitlichen Verschiebungen, dem sogenannten Jitter-Effekt, wodurch eine präzise Rekonstruktion des Audiosignals erschwert wird bzw. nahezu unmöglich ist. To get closer to the pinnacle of audiophile perfection, we also carefully examined the conductor material. Copper in the right purity is itself already an excellent conductor, but a superconductor with no ohmic resistance to the current would be simply perfect. The material’s superconducting properties, however, require extremely low temperatures of at least -70 degrees. Under realistic conditions, silver is currently the most conductive material. With a conductivity of 61.35 S/m (siemens per meter), it outperforms copper by around six percent. Many manufacturers only use silver-plated conductors, which over time can seem, “bright”, “metallic” and even, “annoying”. We, on the other hand, use pure silver, which has a far more neutral sound. Due to the higher drift speed of the electrons, our pure silver cable delivers a more penetrating and sumptuous sound performance, across all frequency ranges. On the other hand of course, silver is about one hundred times more expensive than copper. Neuer 180° USB-Stecker: USB-Stecker können bekanntlich nur in einer Richtung eingesteckt werden. Dies kann mühsam sein, da die Position der USB-Buchsen in Geräten variiert. Um den Verlauf des Kabels anzupassen, muss es oft stark verdreht werden, was Kabel, Stecker und Buchsen strapaziert und zudem unschön aussieht. Die von uns neu entwickelten USB-Stecker mit 180°-Drehmechanismus bieten eine Lösung: Sie können jeweils um +/- 45 Grad gedreht werden, was bedeutet, dass von Stecker zu Stecker insgesamt eine Drehung von +/- 90 Grad möglich ist. Dies ist der letzte Feinschliff für eine perfekte Verkabelung. Die dichte Abschirmung des Referenz USB-2405 AIR Kabels schützt das empfindliche Signal vor elektromagnetischen Interferenzen. Unter der Abschirmung befindet sich die innovative Air-Helix-Konstruktion, wobei Luft und der Abstand der Leiter als Isolatoren fungieren, die dielektrische Verluste verhindern und kapazitive Lasten erheblich reduzieren. Insgesamt erleichtert dies dem Digital-Analog-Wandler (DAC) die Arbeit und perfektioniert die Rekonstruktion des Audiosignals.
The air helix design of the Referenz USB-2405 AIR is entirely unique. We’ve developed a special clip to achieve practically perfect air insulation. Inside the cable, in the right numbers these clips form a supporting structure that keeps the helically-arranged signal conductors apart in the air, and guides them through the high-density shielding at a specific distance from each other. The flexibility of this structure is ensured with two struts, which both hold the clips together and fix them at an exact distance from each other. In the proper sense of the word, “digital” only exists in mathematics in the form of the binary number system. There are no purely digital signals in the technical world. Electrical voltage limits and time windows are defined to detect zeros and ones. The jump from a zero to a one or vice versa always requires a certain time, during which the signal level passes through all intermediate values, from 0 volts to 5 volts, for example. Capacitive loads, dielectric losses, noise and electromagnetic interferences caused by cables additionally manipulate this change. This results in temporal shifts, or the, “jitter effect”, which makes precise reconstruction of the audio signal difficult or almost impossible. New 180° USB connector: As we know, USB connectors can only be inserted in one direction. This can be difficult, as the position of the USB sockets in devices varies. To adjust the course of the cable, it often has to be twisted quite a lot, which puts strain on cables, connectors and sockets and also looks unsightly. Our recently developed USB connectors with 180° rotation mechanism offer a solution: Each one can be rotated by +/- 45 degrees, enabling a total rotation of +/- 90 degrees from connector to connector, thus providing the finishing touch for perfect cabling. The dense shielding of the Referenz USB-2405 AIR cable protects the sensitive signal from electromagnetic interferences. Under the shielding is the innovative air helix structure, where air and the spacing between the conductors act as insulators, preventing dielectric losses and significantly reducing capacitive loads. On the whole this makes the digital-to-analog converter’s (DAC) work easier and perfects the audio signal’s reconstruction.
