As a result of both ingenious construction and the purity of its raw materials VOVOX® Sonorus Protect A 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 or as a patch cable.


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

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 color pigments is almost completely avoided.

Additional conductor for ground
The conductors within a cable must fulfill 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. However, 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 compromising 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.

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


“VOVOX sonorus redefines the understanding of excellence. The science behind this product ensures a greater appreciation of the entire audio spectrum and improves the performance of whatever studio you work in. This is simply a must-have product for music in the 21st century.”
Paul Groucho Smykle, Island Records (Bob Marley, Grace Jones, Sly & Robbie...)

“I’ve used VOVOX cables both live and in my studio for the last three years, and never cease to be amazed at improvement in clarity and frequency response they deliver. When recording the audio for a forthcoming concert DVD/live CD release, sure we had great mic's and high-end preamps, but I believe that the critical component used throughout was VOVOX cables. They were our “secret weapon” and I have no reservation in totally recommending their use wherever an audio signal needs to be transmitted."
Mike Brosnan

"Why should we settle for less than VOVOX in future in our studio? The difference is simply too serious to go back to normal with standard cables."
Fritz Fey, Studio Magazine

"VOVOX sound conductors are without a doubt the most pleasing musical discovery in recent years. The positive effect on my instruments' sonic performance is impressive and amazing. Whether in the studio or on stage, in direct comparison with conventional cables, the VOVOX cable provides significantly better dynamics, transparency and response. It's impossible, however, to describe the actual quality of the VOVOX cable in words, as the most striking feature is the VOVOX sound conductors' ability to provide a most inspiring musical sound!"
Frank Krocker,  CEO, Frame Works Guitars

"Given the unique opportunity to build a compromise-free high-end studio from scratch, we evaluated all equipment components during numerous listening sessions. All well-established cables available on the market were included. We were extremely amazed that for the first time, all those involved unanimously agreed. It is surely not a matter of taste: There are several good cables available, but only one sound conductor. The consequence of using VOVOX was an obvious improvement of sound quality: The richness in detail, directness of sound and mainly the natural character of the stereo-image were unequaled. Using VOVOX, it seemed as though the music was not coming out of the loud speakers any more: It simply was in the room. Incredible!"
Kai Mäder, www.fwlstudios.com

"For this review I concerned myself with one question: can three "blindfolded"listeners tell the difference between Mogami XLR cables and VOVOX? Wow- yes. [...]"
Joseph Lemmer, TapeOp Magazine

"There is no going back when using VOVOX conductors. With an open program image that sits much closer in the listening field and a defined bass response, simply unattainable from conventional cables, this technology marks the standard in high definition recording."
Kieran Lynch, BE, M.Eng.Sc. Recording Engineer

"VOXLINK protect S cables bring very clear improvement in sound quality and definition. The LF is extremely defined with better articulation and sustain of the very low-end and increased clarity of each note. Midrange sounds appear closer and more defined, which gives the entire mix a new perspective of depth and instrument placement. The HF is just more natural and closer to the truth harmonic content of the original instrument without any harshness. The VOVOX cables provide better reproduction of dynamics, especially in the low-end, with incredible instrument separation in the sound stage. The imaging is very detailed and low level sounds are not blurred anymore. The improved tonal clarity provides a sense of proximity to the reproduced sounds and an incredible realism. A major improvement in the audio chain!"
Christophe Anet, B.Eng. in Electroacoustics

"The difference between conventional Pro-Audio cables and VOVOX sound conductors isn't just "splitting hairs" or subtle audio esoterics, in my opinion. It's my experience that with VOVOX, the transients and sound textures become crystal- clear and highly musical. Incredible density, openness and richness of detail allow the sound to become a stunning experience. I'd say it's almost rude to have waited with unveiling this great sounding cable till now… "
Patrik Schwitter, Recording, mix & mastering engineer

"As big as my initial skepticism was the surprise from the test: clear, pure voices, an altogether airier sound. I do not know how any other measure could provide similar sound improvements at a comparable price."
Andy Mejuto, Station Design ENERGY Zürich/Stuttgart/Berlin, RADIO BASEL 1, Swiss National TV SFDRS

"I received the cables a few days ago and all I can say is AMAZING! I was already using a "high end" cable from another manufacturer and I can't believe what a difference the VOVOX cables are making. My old cables sound veiled and somewhat cloudy in comparison. I'm using the pair of VOXLINK direct S cables between my D/A and powered monitors (a pair of ADAM S3A) along with the POWERVOX AC cable. The difference is astounding! High frequency quality has improved in a big way; the top end is way more open sounding and the distinguish-ability of notes in the high register is increased in an obvious way, cymbals sound way more natural. Switching out the power cables to the POWERVOX AC cables increased the tightness and definition of the low end, also improved was depth of field and imaging....just wonderful! Overall the cables impart a more natural, lifelike vibe to everything I've tested it on, by comparison other cabling I have seems to be more hyped and colored sound. I've tried other cabling and overall I find VOVOX to be more musical than other things I've used. Thank you for a wonderful product!"
Michael Perez-Cisneros, Sound Engineer
