Non-shielded balanced cable

VOVOX® sonorus direct S is the result of long experience and countless tests. An unmatched resolution is achieved thanks to the elaborate design of this sound conductor. The excellence in transmitting subtle details regarding spatial imaging, offset in depth and harmonics is incredibly impressive.

VOVOX® sonorus direct S is an uncompromising, non-shielded cable. A small risk of interference must be taken into consideration.

  • single solid core conductors for signal and ground
  • conductors made of the purest available copper
  • natural fibers netting around every single conductor wire
  • pigment and plasticizer-free high purity polymers
  • not shielded


Made in Switzerland

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

Connectors for VOVOX® sonorus direct 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. Since most phone plugs available on the market are designed with only their mechanical properties in mind, we use our own VOVOX® phone plugs:  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

Highest quality conductor materials

The selection of the right conductor material is crucial for the sound. The basis of all VOVOX® sonorus cables are solid core conductors made from ultra-pure copper. Each wire is covered by a netting of natural fibers. This prevents from so called triboelectric noise and further enhances sound quality.

Ultra-pure polymers

VOVOX® sonorus sound conductors are covered with high-tech polymers. 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 almost completely 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.
