Instrument cable

The VOVOX® sonorus XL protect A is our most extreme instrument cable. If you think you already got the most out of your instrument.. get ready to be surprised. The outstanding dynamics, sonority and purity of the sound are something that we previously considered impossible to achieve. The drawback: sonorus XL sound conductors are extremely stiff: you will either love or hate them - or maybe both!

      • Extra large solid core conductors for signal and ground
      • Conductors made of the purest copper available
      • Natural fibers netting around every single conductor wire
      • Capacitance of merely 100 pF/m
      • VOVOX-typical cable construction with screen and separate conductor for ground


Important instructions for use

VOVOX® sonorus XL protect A are stiff and heavy. For this reason, please consider the following:

      • Choosing the right connector shape (angled or straight) ensures the highest durability
      • This cable is not suited for live use
      • Special handling care is recommended
      • The warranty time is limited to 2 years

Made in Switzerland

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

Connectors for VOVOX® sonorus XL 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
  • 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 XL cables are solid-core conductors made from oxygen-free, 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.

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 XL protect A has a very low capacitance of only 100 pF/m.

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.
