"Point-to-Point Air Helix" for pure sound Air as the ultimate dielectric minimizes capacitance Cross Link Super Speed waveguide for a balanced sound Overview Because the largest cu rrent of the entire device chain flows in the loudspeaker cable, a reasonable conductor cross-section is required in order to transport the current 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. Speaker cables should therefore above all have a low inductance - this is exactly what is consistently implemented in the LS-1205 Air: A particularly sophisticated arrangement of the conductors, the 4-fold "multi-core" structure, reduces the inductance value of the cable so that it is over behaves completely sound-neutrally over a wide frequency range. In addition, the magnetic fields created around the individual conductors overlap and neutralize each other. All frequencies are transported unhindered and without any time delay, which enables an incredibly open and detailed musical representation. The four conductors of the LS-1205 Air are divided into so-called aluminium splitters at the end of the Air Helix for the plug connection. In the area between the splitter and the connector, Inakustik uses highly flexible moulded parts made of a special elastomer. These are fixed in the splitter with a specially developed plastic plug. This means that the cable remains reliably flexible even in the connection area. The molded parts extend to the front part of the connector and enclose their inner workings - which underlines the simple and attractive design of the LS-1205 Air. AIR Background It is widely known that the so-called 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 a few hundred cubic centimeters of dielectric substance in the form of insulating material. This dielectric stores electrical charge, i.e. energy - which is entirely desirable and necessary in electronic components such as capacitors. With cables, however, the resulting capacitance is considered a “parasitic” effect and is undesirable for genuine music playback because it significantly influences the transmission properties and leads to interactions with the connected electronics. The air helix structure guides the conductors freely floating through the cable The air helix structure allows for almost 100 percent air content between the signal conductors. Specially developed clips form the supporting framework. Lined up inside the cable, a large number of clips lead the signal conductors freely in the air in a helical shape through the cable. The flexibility of this construction is achieved via two bars that hold the clips together and precisely at a distance. This architecture is unique. The result is low line capacitance and low dielectric losses - an audiophile milestone for open and genuine sound experiences. Inakustik's physical approach: Minimize losses for faithful reproduction The reference AIR cables transport the audio signals unadulterated and with little loss between source, amplifier and loudspeaker. You experience music as the artists expressed it emotionally at the moment of recording. Sensual, fine, funny, orchestral to thrilling, rocky. Vocals and instruments are conveyed authentically. Everything seems alive. Emotions jump out suddenly. The pieces of music touch and awaken feelings, even after listening to them for the hundredth time. Features: The AIR Helix: The air helix structure guides the signal conductors in a free-floating manner through the cable and allows for almost 100 percent air content between the signal conductors. Dialectric: Air as a dielectric reduces the capacity to a minimum. Compared to other insulators, air does not have any capacity-increasing properties and does not produce any dielectric losses. Multicore structure: The clever arrangement of the conductors in the multiple nested multicore structures creates overlapping areas of the magnetic fields that significantly reduce the inductance. The ladder: The Cross Link Super Speed waveguide avoids so-called skin effects. It delivers a balanced sound even with complex music passages and high levels Pressed contacts: The connectors are pressed directly into the conductor material of the cable using a special tool with a force of 1.5 tons. Contact resistance or other negative effects of soldering are avoided. Point-to-Point Air-Helix for seamless transition into the connectors New in the 5th generation is the point-to-point connection of the Air Helix construction from Inakustik. Specially designed transitions for every type of cable and connector ensure a direct, immediate connection. From cable start to cable end, AIR helix construction from point to point. What sounds banal at first has an impact. The sound signals are transported with little loss, even the last few centimeters. The sound is even more detailed and dynamic. The multicore structure A critical conductor in loudspeaker cables is inductance. The clever arrangement of the conductors in the multiple nested multicore structures creates overlapping areas of the magnetic fields that significantly reduce the inductance. The entire frequency spectrum, including high tone frequencies and dynamic pulse sequences, are transmitted unhindered and without any time delay. Music sounds more detailed. The sound is more finely dynamic. All details are worked out precisely and harmoniously at the same time. The ladder structure The Cross Link Super Speed waveguide avoids skin effects caused by eddy currents in the conductor. Thanks to the braided structure, the waveguide transmits even extreme current peaks precisely. A layer of varnish around each wire prevents eddy currents within the conductor and protects against oxidation. The result is a conductor that transmits a balanced sound image with lively timbres that are not overemphasised in any area, even with complex music passages and high levels. The conductor material The conductor material plays an essential role in the transmission of sound signals. Any contamination worsens the conductance and increases the background noise. Inakustik only use pure, oxygen-free copper in their AIR cables. They attach particular importance to only using high-purity copper batches. The quality of the copper is determined in complex processes before it is drawn to the required diameter in the wire drawing machine over several stages. Rhodium plated The best cable requires optimal connection technology. We use tellurium copper, a harder metal alloy that maintains the high conductivity. Compared to brass connectors, the conductivity values are significantly better. The rhodium coating ensures long-lasting contact and corrosion resistance. Even with frequent modifications, the stable conductivity is maintained. This is better than gold contacts, which wear out more quickly. Pressed contacts (1.5 tons) The contact elements of the plugs are pressed directly into the conductor material using a special tool with a force of 1.5 tons. This creates a stable and reliable connection without the use of solder or ferrules. Contact resistance and negative effects are avoided to ensure optimal signal transmission.
