The AirGap isolation

AirGap isolation

The ‘AirGap’ isolation is a technique when Air is used to insulate an audio cable. This is achieved by isolating the cable from external interference. A Power cord, Interconnect cable, and Loudspeaker cables are items which benefit from this technique.

This process is similar to double glazing. Double glazing is used to insulate the interior of a house to keep it warm. By Insulating the interior, the house is isolated from external noise and vibration. When triple glazing is used, the results are even better. And in the same manner, audio cable isolation is necessary to reduce the effects of external Vibrations.

Power cord

AirGap steps

The picture shows a white power cord running from left to right. Over the power cord, runs a layer of black material called CanuFlex PE-HB. This material has a very fine ‘mesh’ which is used to trap pockets of air. 

The CanuFlex PE-HB is covered with a green sheathing material DeRay-PBFSP. The material is slowly heated to a predetermined temperature. As the DeRay-PBSFB contracts, the air is trapped and insulation is formed around the cable. A second layer is added when the process is repeated. A third layer can be added if necessary.

he ‘AirGap’ isolation process makes an audio cable perform better. This is because the cable is isolated from external vibration and interference.

Composition
  • Perkune audiophile ‘AirGap’ insulation has over 720 pockets of trapped air per square inch. These pockets of trapped air are in the material which runs around the entire length of the cable. 
The example
  • A Perkune audiophile power cord has a diameter of  9.0 mm.
  • And, after three levels of isolation, the power cord diameter increased from 9.0 mm to 15.0 mm.
  • An increase of 40% which gives excellent results in cable performance.
  • The Power cord is flexible and easy to use.
AirGap end view
  • First, level ~ 17,280 pockets of ‘trapped’ Air.
  • The second level ~ 34,560 pockets of ‘trapped’ Air.
  • Third, level ~ 51,840 pockets of ‘trapped’ Air.
  • The results are with a two-meter Power cord.
Aluminium foil

Noise is the enemy in audio or, rather excess and unwanted noise. And, so I found a solution. Aluminium foil provides better sound insulation and helps to eliminate unwanted noise sources. 

Aluminium foils ability to absorb sound allows unwanted noise to be picked up directly at the source and prevent its further propagation. Aluminium foil offers 85% effective as a noise insulator. Which means, only 15% of the respective sound passes through it and an ideal component for use in audio cables.

Tip to Tip
Power cord two meter

Power cord insulation is taken from inside the top plug to the bottom plug. The insulation is also taken to the termination screws. This gives the ultimate connection and reducing the effects of mechanical and electrical vibration.

XLR connections

Working with interconnecting cables, the Canuflex PE-HB is taken over all connections. This is ‘tip to tip’ coverage which ensures perfect isolation from external interference.

Antivibration connections

When applied to a loudspeaker cable, the Canuflex PE-HB is taken over all connections. This is giving ‘tip to tip’ coverage. Which ensures perfect isolation from the effects of mechanical and electrical vibration.

Conclusion

The ‘AirGap’ isolation process can be applied to any cable where isolation is required. The performance is greatly improved by using these techniques regardless of the system price.

I have been testing for months and have excellent feedback from my colleagues and customers. The results inspired me to improve the range using the ‘AirGap’ isolation and Anti-vibration technique. A person is now able to hear more of the musical presentation than ever before, which in itself is inspiring!
