Dielectric-Bias System Makes the CV-4 Difference

"The cable market is filled with new 'wonder' technologies that are little more than marketing gimmicks," reports the February / March 2004 issue of The Absolute Sound. "AudioQuest's Dielectric Bias System (DBS) is not one of them. Instead, this simple yet effective technique elevates the performance of AudioQuest's already superb designs to a new level of performance."
A Battery on a Speaker Cable?
AudioQuest's CV-4 has long been one of the company's most popular speaker cables. Now AQ goes a step beyond by combining the winning geometry and advanced materials of CV4 with its revolutionary Dielectric-Bias System technology, which adds a battery to new CV-4 DBS speaker cable.
Did we say batteries on an speaker cable? (Psst, proofreading, guys.) AudioQuest introduces an astonishingly simple solution to a universally acknowledged problem.
The effect of dielectric (or insulation) on cable performance is universally acknowledged. No insulation, other than a vacuum, is perfect. All insulation conducts some tiny degree of electricity in the presence of an electrical field, and this effect can cause distortion and signal loss.
[And this is somehow a problem in a speaker cable being driven by an amplifier with extremely low output impedance?]
The grossest errors caused by "dielectric involvement" occur when the dielectric hasn't been given sufficient time and voltage to stabilize. Breaking in a cable simply means allowing time for a cable's dielectric material to adapt to a charged state. But what if a charge were present from the very beginning of a cable's life, allowing the dielectric to maintain a 'stable' state?
[And "stable" (DC) states apparently are somehow vital to a cable carrying an AC signal.]
The AudioQuest DBS Difference
AudioQuest's patent pending Dielectric-Bias System (DBS) puts all of a cable's dielectric into a comparatively high-voltage DC field beginning at the moment that the cable is terminated. This exceptionally simple design puts a wire down the middle of the cable, which is merely an extension of a battery's anode. In other words, this wire is attached to the positive terminal of the DBS battery pack and not to anything else. The wire is not in the signal path and has no interaction with the signal.
[And since it does not form a closed circuit loop, it does nothing except bias any minuscule leakage resistance with a minuscule leakage current.]
The shield or outer spiral of conductors is used as the DBS cathode by connecting it to the negative terminal of the battery pack. Again, there is no interaction with signal flow and no extra connections are introduced into the signal path. The batteries are doing no work. They will last as long as the batteries sitting on your storage shelf, so you will very seldom need to change batteries. To check battery status, the DBS pack includes a button and LED.
[So, NO current is flowing (what aboot that there leakage current) and the battery will last as long as its shelf life.]
Hearing is Believing
The benefit of maintaining a constant bias on the dielectric is dramatic. Even a cable which is fully 'broken in' or which has the loudest music or pink noise continually traveling through it never has a fully formed dielectric compared to what the AudioQuest Dielectric-Bias System achieves. In fact, imagine an improvement of double or triple that of a normal 'broken in' cable, and you begin to get an idea of what AudioQuest's Bill Low says can be achieved with the DBS system.
According to The Absolute Sound, "The sonic result is a deepness to the silence, high resolution of fine detail with etch, and greater transparency."
[So, the silence is even more deafening.]
The Perfect Surface Copper Cable
Here's proof that metal quality can make a huge difference. AudioQuest CV-4 uses the same exceptionally efficient design as its popular Type 4. But by using Perfect Surface Copper (PSC), Spread Spectrum Technology (SST), and spiral construction, CV-4 is able to "get out of the way" far more completely. The result is a cable that's smooth, pure, clean, and dynamic.
This is No Ordinary Cable
CV-4 might look like a normal round cable, but inside is a fully optimized combination of extraordinary materials and extremely refined design. All four of CV-4's conductors are solid. Electrical and magnetic interaction between strands in a conventional cable is the single greatest source of distortion, often causing a somewhat harsh, dirty and confused sound. Solid conductors are the most important ingredients of CV-4's very clear sound. Whether a conductor is solid or stranded, skin-effect is a prime distortion mechanism in speaker cables. CV-4 very simply keeps this effect out of the audio range by using conductor sizes that are below the threshold for audible distortion.
A Super Sonic Technology
SST stands for Spread Spectrum Technology, an AudioQuest cable innovation. Any single size or shape of conductor has a specific distortion profile. SST significantly reduces distortion by using a precise combination of different size conductors. SST has enabled CV-4 to be the biggest possible four conductor cable that avoids audible skin-effect.
Conductors are made of PSC+ (Perfect Surface Copper+), which has an astonishingly smooth and pure surface. Proprietary metal processing technology protects the wire's surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes a wonderfully low distortion PSC conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra pure copper. The resulting sound quality is even more focused and simply less in-the-way.
The spiral construction of CV-4 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel. The specific 4-cross geometry used in CV-4 maximizes this advantage.
A 12' pair are only $515.

Again, let's leave the math out of this, and just assume two things. One, your average Amateur Radio Operater (HAM) uses between 50 and 500 watts of transmitting power, fed to his/her antenna through a cable (RG-8/U) with a diameter of roughly 1/10th of an inch. That corresponds to 10 ga. in the AWG, which is also used by speaker wire manufacturers. Starting to get a clue yet.......
