VOVOX :: Instrument cable

Instrument cable

The VOVOX® sonorus protect A is our ultimate instrument cable. As a result of both ingenious construction and the purity of its raw materials it offers unmatched sound quality. This is the perfect cable for all electrically amplified musical instruments such as electrical guitar, bass, E-piano or keyboards. Also great for acoustic instruments with pickup systems.

      • Solid core conductors for signal and ground
      • Conductors made of the purest available copper
      • Netting of natural fibres around every single conductor wire
      • Capacitance of 75 pF/m only
      • VOVOX-typical cable construction with screen and separate conductor for ground

Made in Switzerland

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

Connectors for VOVOX® sonorus protect A

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
      • Efficient strain-relief
      • Lead-free soldering

Straight or angled ¼” phone plugs?

Especially in the case of instrument cables, we suggest carefully choosing the kind of connector that suits you best: Using a 90° right angle plug will often reduce the mechanical stress on the instrument as well as on the cable. Like this it contributes to longer service life of both, cable and jack. For acoustic guitars, angled plugs are usually the better choice.

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 fibres. 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.

Optimal protection from microphonic noise

When a guitar cable is moved or stepped on, small electrical signals are created due to the change of the capacitance or due to electrostatic charges. This effect is called microphonic. It creates a disturbing crackling noise. Usually this phenomenon is avoided with the help of conductive plastics. Howevery, like this also sound quality is negatively affected. We have found our own technique to solve the problem of microphonic noise using natural materials – without compromizing sound quality.

Very low capacitance

It is impossible to judge the quality of an instrument cable just based on its capacitance. Nevertheless, to have a low capacitance is a precondition for a cable to transmit the whole frequency range. VOVOX® sonorus protect A has a very low capacitance of only 75 pF/m.

Cable test with instrument cables

The sound samples were recorded for us by Hank Shizzoe. We purposely used a very simple set-up with only few components. The different takes were recorded separately, therefore there are small variations in the audio material. The sound character nevertheless becomes apparent.
