A Technical Path Toward Pure, Uncolored Signal Transmission.
Engineering you can measure.
in-akustik’s development approach is based on well-known physical principles of signal transmission. A cable’s electrical properties - in particular capacitance, inductance, and resistance - are largely determined by material choice, conductor geometry, and construction.
The aim is to minimize unwanted electrical side effects such as high capacitance, inductance, or interactions between the cable and connected components. AIR technology reduces the influence of the dielectric and lowers capacitance; multicore constructions reduce inductance; special conductor architectures optimize the properties within the conductor.
Cables are not understood as sound-defining components. Their job is to transmit the music signal as faithfully as possible between source, amplifier, and loudspeaker - minimizing losses, storage, and interaction effects so the recording is reproduced as it was originally created.
