Description

LS-1205 AIR

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.

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.

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.

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.

The conductor structure

The Cross Link Super Speed waveguide avoids skin effects caused by eddy currents in the conductor. Thanks to the braided structure, the waveguide is able to precisely transport even extreme current peaks. A lacquer coating around each wire prevents eddy currents within the conductor and protects against oxidation. All this results in a conductor that delivers a balanced sound consisting of vibrant and never overemphasized timbres, even in complex musical passages and at high volume levels.

The conductor material

The conductor material is a crucial factor for the transmission of sound signals. Any contamination worsens the conductance and increases the background noise. We only use pure, oxygen-free copper in our AIR cables. We ensure that only carefully selected batches of pure copper are processed. We take great pains to measure the quality of the copper before it is sent to the mill for drawing to the required cross-section over the course of a multi-stage process.

The multicore structure

Inductance is critical to the capacitance of a loudspeaker cable, By cleverly arranging the conductors in the multiply nested multicore structures, overlapping magnetic field areas are created that significantly reduce inductance. This allows the entire frequency spectrum, including high frequencies and dynamic impulse sequences, to be transported in an unimpeded way and with no delays. The music seems more exquisitely detailed, and the sound gains in fine dynamism. All details are kept distinct yet harmonious at the same time.

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.

Handmade

Each cable is handcrafted with the utmost care. Our extensive know-how and the qualifications of our team enable us to manufacture the complex cables in a customized manner. Apart from the finest of materials, our most important resource is the manual dexterity of our cable assemblers. In assembling our outstanding cables, they demonstrate meticulousness, composure and dedication.

Rigorous quality control

We manufacture in accordance with the highest standards. Rigorous quality control is carried out before, during and subsequent to assembly. We verify the tolerances of ever individual component. At every stage of manufacturing, we check the configuration and electrics for short-circuits. We also conduct functional and mechanical testing. No product leaves our manufacturing unit without a final quality check.

Did you know...

......that our LS-1205 AIR (2 x 3 m; SW) is made up of 534 individual components? The copper wire used is 647 m long, and the PE monofilament is 667 m long. Containing 1584 drill holes, the Air Helix design of this cable type demands great dexterity on the part of the assemblers when they’re threading through the conductors.

AIR background

It is widely known that the “dielectric” (= non-conductive substance) of capacitors plays a major role in the sound of hi-fi devices and loudspeakers. The engineers therefore select all components very carefully. Even if they only contain a few cubic millimeters of dielectric: A meter-long cable usually already contains several hundred cubic centimeters of dielectric substance in the form of insulating material. This dielectric stores electrical charge, i.e. energy – which is entirely wanted and necessary in electronic components such as capacitors. With cables, however, the resulting capacitance is considered a "parasitic" effect and is not wanted for unadulterated music playback because it significantly influences the transmission properties and leads to interactions with the connected electronics.

Rhodium-coated

The best cable requires optimum connection technology. We use tellurium copper, a harder metal alloy that maintains the high conductivity value. Much superior to that of brass connectors. The rhodium coating ensures long-lasting contact and corrosion resistance. The stable conductivity is even maintained with frequent conversions. This is better than gold contacts, which wear out quicker.

Pressed contacts (1.5 tonnes)

The contact elements of the connectors are pressed directly into the conductor material using a special tool with a force of 1.5 tonnes. This creates a stable and reliable connection without the use of solder or ferrules. Transition resistances and negative effects are avoided to ensure optimum signal transmission.
