VOVOX® sonorus protect A twin



Dual cable

Often acoustic instruments are fitted with a combination of pickups and built-in microphones in order to optimize the amplified sound-character. By mixing the two signals the sound and the feedback safety can be selectively controlled. The stereo instrument cable VOVOX® sonorus protect A twin was specifically developed for such dual pickup systems.

    • two high-quality instrument cables combined 
      • solid core conductors for signal and ground
      • conductors made of the purest available copper
      • natural fibers netting around every single conductor wire
      • capacitance of merely 75 pF/m
      • 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

Stereo angled phone plugs are not available in VOVOX® phone plug quality. In this case we use connectors from Neutrik (NP3RX-BAG).

Straight or angled ¼" phone plugs?

For acoustic guitars that have their jack integrated in the strap button, angled plugs are usually the better choice. Like this it contributes to longer service life of both, cable and jack.

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.

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.

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.
