NF-204 Micro AIR

Compact air insulation. Symmetrical design.

The NF-204 Micro AIR brings genuine air-dielectric benefits into a compact 6.5 mm diameter interconnect. Its diamond-shaped Micro AIR structures create air chambers between concentric copper conductors, reducing capacitance without the physical bulk of full Air Helix construction. Two-fold shielding (braid + foil) with a floating shield design provides high immunity to electromagnetic interference. Available in both RCA and XLR configurations.

Key Features

6.5 mm Micro AIR Diameter

Diamond-shaped air chambers between concentric conductors deliver genuine air-dielectric benefits in a compact, flexible format.

Symmetrical Architecture

Double mono design with separate signal paths for each channel, eliminating crosstalk.

Two-Fold Floating Shield

Braid plus foil shielding with floating shield construction provides high immunity to EMC radiation from mobile and Wi-Fi networks.

360 Degree Connectors

RCA with rhodium-coated tellurium copper contacts pressure-grouted at 1.5 tonnes; XLR with 180-degree rotatable plugs.

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.

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.

Micro AIR

Air insulation in a compact, flexible format.

Micro AIR technology creates complex diamond-shaped structures within the cable that form tiny air chambers between the concentric copper conductors. This increases conductor spacing and air content without the physical bulk of full AIR Helix construction, reducing capacitance while maintaining the low impedance necessary for line-level signal transmission. The result is a more compact, flexible cable that brings genuine air-dielectric benefits to a wider range of systems.
