Shielded balanced cable

Shielded, balanced sound conductor with optimal noise protection. Offers optimal sound quality for situations in which absolutely no risk of interference can be taken.

      • single solid core conductor for signal and ground
      • silver-plated, oxygen-free copper conductors
      • pigment and plasticizer-free high purity polymers
      • shielded
      • optimally protected against microphonics


Made in Switzerland

VOVOX® sound conductors are hand-assembled in Switzerland. The cables, including the solder, are lead-free.

Connectors for VOVOX® link protect S

XLR Connectors

For our balanced cables, high quality Neutrik XLR connectors with gold plated contacts are used.

TRS ¼" phone plugs

Our pronounced goal is the perfect transmission of sound signals. To achieve this aim, the cable, but also the connectors, must fulfil our requirements. Most phone plugs available on the market are designed with only their mechanical properties in mind. We fully agree that phone plugs must durably resist hard handling on stage. But apart from this, they mustn't be a hurdle for optimal sound signal transmission. For this reason, we now present the VOVOX® phone plug: A ¼" phone plug offering both first class functionality and first class sound.

  • Optimized signal contact made of copper
  • Robust housing made of fiber-reinforced engineering-plastic
  • Optimal bend-protection
  • Lead-free soldering

High-grade conductor material

The selection of the right conductor material is crucial for the sound. The basis of VOVOX® link sound conductors is silver-plated solid-core conductors made from oxygen-free high purity SPOFHC copper. Because silver has an even better conductivity than copper, the current density is additionally enhanced in the important surface boundary.

Ultra-pure polymers

VOVOX® link sound conductors are covered with two layers of high-tech polymer. Although plastics are not directly involved in the signal transmission, they do have an effect on the sound quality. VOVOX doesn't use any PVC. Only ultra-pure plastics without plasticizers are used. Even the use of colour pigments is avoided.

Additional conductor for ground

The conductors within a cable must fulfil several functions. The shield has the main function of protecting the signal conductor from interference. In most cables, the shield is also used as the return signal conductor. VOVOX® consequently separates these functions. This may be a more complex construction, yet it results clearly in better sound quality.

Arrangement of conductors

Current induces electromagnetic fields encircling every conductor. If the distance between two conductors is too small, interactions and interferences are created. The result is an audible loss of sound quality. As a consequence, the conductors are arranged at well-defined, relatively large distances.

Flexibility and durablity in spite of solid core conductors

To offer maximum sound quality, VOVOX is strictly using solid core and not stranded wires. In order to keep the cables flexible and durable, they are designed in a unique way. Every conductor is seperately coated with a polymer jacketing to form a lead. The various leads are helical stranded and covered by a flexible netting. Due to this construction the wires remain in the neutral axis when flexing the cable. Like this it is possible to prevent the wires from critical compression or tension, they are only smoothly bent.
