in-akustik Power Cables
AC-1205 AIR
Entry to Air Helix power. 13 mm. Compact.
The AC-1205 AIR is the entry point to in-akustik's Air Helix power cable range. Its compact 13 mm diameter houses 2 x 1.5 mm² of high-purity copper in a 4-fold multicore configuration with full Point-to-Point Air Helix insulation. Dense tin-plated copper braid shielding blocks electromagnetic interference, and Referenz Basic gold-plated connectors provide a solid, reliable connection. A genuine Reference cable at a more accessible price point.

Dense Copper Braid Shield
Tin-plated copper braid shielding blocks electromagnetic interference from mains pollution.
Technologies Inside
AIR Technology
Air is the perfect insulator.
Now in its fifth generation, AIR technology uses air as the primary dielectric instead of traditional plastics like PVC. Conductors run freely suspended through the cable via precision-engineered clips at defined intervals, reducing capacitance by approximately 83% compared to standard cables. The Point-to-Point Air Helix architecture extends this principle from connector to connector for almost loss-free signal transmission.
Multicore Architecture
Overlapping fields, lower inductance.
in-akustik's multicore conductor arrangements use four-fold structures where the overlapping magnetic fields of individual conductors deliberately cancel each other out. This reduces inductance and minimises the skin effect at high frequencies, delivering a more neutral, dynamic frequency response.
AIR Helix Point-to-Point
Air insulation from plug to plug.
Specially designed clips suspend each conductor at fixed distances within the cable, using air as the primary dielectric from connector to connector. Air has the lowest dielectric constant of any insulating material, minimising capacitance, energy absorption, and dielectric losses. The result is instantaneous current delivery on dynamic peaks — no energy is stored and released with delay by conventional plastic insulation.
