Shielding


Shielding is used to protect the signal conductors from RFI and EMI. Braided shield is good for EMI, and foil for RFI. Combinations (foil and braid) are used for long runs for RF cables.

TARA Labs exclusive Parallel Shielding System was formulated to "common" any electrical potential (EMI interference voltages) between shields in RSC® Master Gen 2 and RSC Air™ interconnects. Our parallel shields connected together act as a 'star-ground' for the shields and the RFI/EMI radiation. By commoning the electrical potential in the shields, a better 3-dimensional reproduction of the soundstage is achieved due to both channels having the same level of reduced background noise. Example: A preamp's transformer often concentrates radiation more toward one channel of the interconnect pair. If there is no shield, RFI would be modulated with the audio signal, often making the high frequencies sound bright or grainy. When shielding is used this sonic glare is reduced. When the shields are commoned, the left and right channels' bandwidth and EMI interference effects are far more equal channel to channel. The result is better imaging, spatial cues and a naturally quiet background.

All my HFX boxes are earth grounded to an 8 foot ground rod.

Jebsmith73, how did you do that kind of grounding?, if the ground is to long,it does not work as good, just like most house ground's, an example, I run a 25ft dedicated ground for my amplifier, and in turn, that sound real distant, crashed the sound stage etc..., connected my amp ground back to the inside the breaker box, and the box is exactly oppisite from the main power box on the brick side-out side of the house that uses a 4ft earth ground, sounded hugely better in every way, this is the way the dedicated line for the amp is connected now, it's by code, but the main reason I did the code was because of the shortest possible ground that I can possibly have here without getting a dedicated breaker box for intire system, cheers.

Hi colekat, interesting story, would you know what the grounding problem was connecting to the preamp?, Happy Listening.

Dielectric's play a major role in how a cable will perform,it is best to know exactly what dielectric you have in a cable, what it's design purpose is and if it does what it was designed to do, here is an explanation of what dielectric is,


Insulating materials exposed to electric fields are called "dielectrics." Dielectrics are necessary parts in the construction of any cable because they prevent oxidation and keep the conductors from touching one another. In audio cables, relatively low voltage and current levels mean that dielectric strength is not the most important factor. Far more significant in its effect on the sound is a material's dielectric absorption. This characteristic describes the way a dielectric may discharge a secondary signal into the conductor out of phase with the audio signal.

As a current is passed through a conductor, an electromagnetic field is created which interacts with the dielectric material and temporarily displaces the molecular structure. If the dielectric material has good elasticity and can return quickly to its normal state, then the material is said to have low dielectric hysteresis or loss and will have little audible effect on the signal.
