in-akustik Power Cables
AC-2405 AIR
Reference Air Helix power. 25 mm. 4-fold multicore.
The AC-2405 AIR brings Air Helix technology into a 25 mm diameter power cable with 4-fold multicore construction. Its 2 x 3 mm² high-purity copper conductors are split into four individual wires for reduced inductance, while dense tin-plated copper braid shielding blocks electromagnetic interference. Available with Referenz UHQ rhodium-plated or Basic gold-plated connectors in both C15 and C19 configurations.

Key Features
25 mm Air Helix Diameter
Generous conductor spacing within the Air Helix architecture for effective air insulation in a more manageable diameter.
4-Fold Multicore Construction
2 x 3 mm² cross-section split into 4 x 1.5 mm² conductors for reduced line inductance and minimised skin effect.
UHQ or Basic Connectors
Choose Referenz UHQ rhodium-plated for maximum performance, or Basic gold-plated for an accessible entry into Air Helix power delivery.
Dense Copper Braid Shield
Tin-plated copper braid blocks electromagnetic interference and prevents oxidation for long-term performance.
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.
