Phono-1205 AIR
Compact Air Helix phono cable. 13 mm.
The Phono-1205 AIR is the most accessible Referenz-grade phono cable, applying the same Point-to-Point Air Helix principle to a compact 13 mm cable diameter. High-purity OFC copper Cross Link Super Speed conductors and dense tin-plated copper braid shielding protect the cartridge's microvolt signal across the full audible band. All termination and socket combinations (SME-90°, SME straight, 5-pin DIN, RCA, XLR) are available across the Phono AIR range — contact us for the configuration your tonearm requires.

Key Features
13 mm Air Helix Architecture
Compact Referenz-grade air-dielectric construction — conductors held in air by Point-to-Point clips for low capacitance.
High-Purity OFC Copper
Cross Link Super Speed waveguides built from oxygen-free copper with lacquered individual wires prevent eddy currents for clean cartridge signal transfer.
Double-Shielded Construction
Dense tin-plated copper braid shields the phono signal from RF, mains noise, and nearby electronics.
Matched to Your Tonearm
SME to dual RCA as standard. SME-90°, 5-pin DIN, and XLR combinations all available — specify your tonearm connector when ordering.
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.
Cross Link Super Speed
Eliminating eddy currents at high frequencies.
Cross Link Super Speed waveguides are hand-threaded into the cable structure to prevent eddy current effects at high frequencies. This preserves the full detail and extension of the audio signal across the entire audible spectrum, ensuring transients remain sharp and high-frequency information arrives intact.
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.
360 Degree Pressure-Grouted Connectors
Three-axis rotation. 1.5 tonnes of force. Zero solder.
in-akustik's 360-degree BFA banana and spade lug connectors move across three axes, making connection and disconnection effortless while preventing cable stress. Instead of soldering, which introduces additional metal alloys and weak points, each connector is pressure-grouted at 1.5 tonnes of force — creating a gas-tight, vibration-resistant bond. BFA bananas use beryllium copper with solid metal housings, while spade lugs use tellurium copper, both rhodium-coated for lasting conductivity and corrosion resistance.
AIR Helix Point-to-Point
Fifth-generation air insulation, from plug to plug.
The AIR Helix design suspends conductors in a helical arrangement through the cable using specially engineered clips at precise intervals. Air replaces traditional plastic insulation as the primary dielectric, reducing capacitance by approximately 83%. The fifth-generation Point-to-Point innovation extends this architecture from connector to connector, with specialised transitions for each plug-cable combination eliminating the last remaining sections of conventional insulation.
