AIR technology: natural & voluminous sound

Our Air technology is the product of our profound in-house expertise and years of development work. The technology sets new standards. Audio signals are impacted by a variety of factors: resistance, inductance, capacitance, insulation and skin effects all have a negative influence on the sound. As a result, the fragile signals are distorted during transmission. Our specially developed AIR technology reduces any resulting losses to a minimum. The 5th generation of this technology is now available.

High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore
The LS-2405 AIR high-end speaker cable offers audiophile enthusiasts a unique sound experience. In the new Referenz LS-2405 AIR loudspeaker cable, we have taken the outstanding properties of its predecessor, the LS-2404 AIR, and developed them even further. The point-to-point Air Helix design now enables the AIR Helix architecture to be used from plug to plug and not just between the sleeves. The 360° BFA bananas and spade lugs are a further innovation, developed in-house for easy and convenient connection to the terminals. These and other technical refinements turn the already exceptional AIR cables into true masterpieces. Below you can learn more about the outstanding technical features of this cable, the innovations in the 5th generation and the physical principles used in the AIR technology Click here and discover the exciting details

High-end speaker cable Quality: Referenz AIR Helix Point-to-Point | Multicore
Because the speaker cable carries the largest current in the entire device chain, a suitable conductor cross-section is required to transport it with as little loss as possible. This current generates correspondingly strong magnetic fields and, since it is alternating current, there is a frequency-dependent resistance in the inductance of the cable. Low inductance is therefore particularly important for speaker cables - and this is precisely what has been achieved with the LS-1205 Air: The cable's inductance value has been reduced by a particularly ingenious arrangement of the conductors, the 4-fold "multicore" structure, enabling it to behave in a completely sound-neutral way over a wide frequency range. In addition, the magnetic fields generated around the individual conductors overlap and neutralize each other. This means that all frequencies are transported unhindered and without any time delay, enabling a fabulously open and detailed musical presentation. At the end of the air helix, the LS-1205 Air’s four conductors are separated into so-called aluminum splitters for the receiving connector. In the area between the splitters and plug, in-akustik uses highly flexible molded parts made of a special elastomer. These parts are fixed inside the splitter using a specifically designed plastic plug. This means that the cable remains reliably flexible in the connection area as well. The molded parts run right to the front of the connectors and enclose their inner workings - which underscores the sleek yet attractive design of the LS-1205 Air.

High-end audio cable Quality: Referenz AIR Helix Point-to-Point
Breathtaking sound thanks to air insulation - we have already created many innovative designs on the way to perfect insulation, such as DUO-PE insulation or PETS (PE Tube Support). The Referenz NF-2405 cable is another true milestone and an absolute world first in the cable sector. Normally, the conductors are kept at a distance from each other by more or less high-quality filling and insulation materials. With the NF-2405, however, the conductors run through a series of clips connected in series, which form the inner framework and give the NF-2405 exceptional flexibility for high-end cables. The NF-2405 is manufactured entirely in Germany, like all speaker and audio cables in the Referenz series. The clips are assembled by hand with meticulous care in the company's own factory and then the Cross Link super-speed waveguide is threaded in. The resulting Air Helix is then also shielded by hand and fitted with a PE network jacket before the finished cable is assembled with the XLR 180° connectors developed in-house. New XLR 180° plug: It is only possible to insert XLR connectors in one direction. This can be annoying as the position of the XLR sockets in devices varies. In order for the cable to fit, it must sometimes be twisted by force. This puts a strain on cables, plugs and device sockets and sometimes simply looks a mess. The new XLR 180° plugs developed in-house can be rotated by +/- 45 degrees, i.e., up to a total of +/- 90 degrees from connector to connector. The finishing touch for perfect cabling.

The good old record sounds more vibrant than ever. The demand is astonishing, even for experts. The figures for records sold are increasing just as surprisingly as the number of record players. It’s a real boom. But how to improve the sound? One way is to use a new, better cable between the tonearm and the phono amplifier. The Phono-2405 AIR is a cable created to deliver top sound. What sets it apart is an absolutely unique air insulation, called the Air Helix. We have developed a special clip for this technology. It separates the two cable bundles, keeps them apart, and virtually embeds them in air. Using a large number of these clips, it is possible to route earth and signal extremely stably over longer distances. Why the effort? With this approach it is possible to pass on the sensitive signals without slowing them down - the result is fast and high-resolution sound. The Super Speed waveguides are threaded by hand and the clips are fitted with great care in the company's own factory. After this, the resulting Air Helix is also shielded and fitted with the PE network jacket by hand. Finally, the rhodium-plated connectors are fitted and cable functionality is tested. Because it's all about the most important, smallest signals: There is nowhere in the audio world where smaller currents flow that need to be passed on perfectly. The signal level of an MM or MC system is extremely sensitive, at just a few thousandths of a volt. In addition to this, the systems have an inductive character. In combination with the cable capacitance, they form what is known as an oscillating circuit, which favors specific frequencies. If these frequencies are unfavorable due to excessively high capacitance, this has a major effect on the harmony of the sound. Extremely low capacitance and dielectric losses are just two advantages of the Referenz Phono -2405 AIR. They form the basis for unadulterated enjoyment of your vinyl jewels. The sound of good records can hardly be resolved in a finer way than this. Click here and discover the exciting details

High-end digital cable Quality: Referenz AIR Helix Point-to-Point
Length: 1 m
The Air Helix architecture of the Referenz Digital-2405 AIR is absolutely unique. We have developed a special clip that enables us to come as close as possible to perfect air insulation. Inside the cable, a large number of these clips form the supporting structure that keeps the helically-arranged conductors apart in the air and guides them through the shielding at a defined distance from each other. Cable flexibility is assured by means of two struts that ensure the clips remain together but also at a precise distance from one another. With coaxial cables, the shielding is generally also used as a ground wire. The Referenz Digital 2405, on the other hand, has a double-symmetric design with two positive and two negative conductors. This means that the shielding is completely separate and the signal remains free of interference. Even if it sounds paradoxical, thanks to the innovative air insulation in this cable, hi-fi becomes a simply breathtaking sound experience. Click here and discover the exciting details

High-end mains power cable Quality: Referenz AIR Helix Point-to-Point | Multicore
Length: 1.5 m | Connector: SCHUKO> C19
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.

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. New XLR 180° plug: It is only possible to insert XLR connectors in one direction. This can be annoying as the position of the XLR sockets in devices varies. In order for the cable to fit, it must sometimes be twisted by force. This puts a strain on cables, plugs and device sockets and sometimes simply looks a mess.
