Audio Problems In Cables

Skywire Audio discovered that many of the problems in audio cables are the results of Radio Frequency (RF) noise and ringing in the cables. The ringing is caused by RF reflections from the ends of the cables at the fundamental and harmonic frequencies. Since the RF is above the audio band, it does not show up in normal audio band test measurements and is ignored.

Source Of RF Energy

The sources of the RF in the system include being conducted in from the power lines, received from airborne radiation (radio stations, wireless telephones, etc.), and internally generated within the system. All digital circuits create megahertz square waves which generate broadband RF.

Ringing is easy to change and hard to kill. The technique that we use to reduce the ringing is to put highly efficient RF absorbers around the cable. The RF absorbers kills the ringing that builds up in the cable.

The RF absorbers are metallic and do not contain any ferrite. We have found that the use of ferrite is not sonically desirable in the application. Ferrite tends to cause a dry analytical sound and thin out the higher frequencies. Skywire RF absorbers are the key to the sound quality of our cables and are covered under US patent.
