Conventional cable isolation theory holds that optimal cable performance can be achieved by elevating cables from the floor in an attempt to control vibrations and manage static fields. Typical cable elevators are made from electrically insulating materials such as wood, glass, plastic or ceramics. Most of these products claim superior performance based upon the materials or methods of elevation.
The central problem with the conventional model is that elevating a cable from the floor with an electrical insulator creates a relative static charge differential between the cable and floor. Over a period of time this static differential can become enormous -- sometimes exceeding tens of thousands of volts. When an electrical signal is sent through the cable, the signal can become distorted or inter-modulated by the static electrical field differential between the cable and floor. This effect is similar to sending an electrical signal through a wire that passes through a powerful magnetic field. The distortion that results is quite audible with any quality entertainment system.
The Shunyata Research Dark Field Cable Elevator is based upon a patent-pending static-field-unification principle. The elevator is constructed from expensive, multiple layers of electrically conductive foam. This allows static charges to migrate through the elevator eliminating the build up of static field differentials between the floor and cable that would otherwise create noticeable signal degradation.
In addition to eliminating static-field differential effects, Dark Field Elevators minimize the transmission of vibrations by combining two soft layers of vibration absorbent foam with a third rigid layer that has a different resonant frequency. This not only minimizes floor-borne vibration, but also breaks up standing-wave vibrations within the elevator itself. The Dark Field Elevator's s extremely narrow inner layer is formed into a V shape that limits the surface contact area. This minimizes the transmission of vibrational energy from the floor to the cable, while providing a stable and firm support.
Placing Dark Field Elevators under signal cables, speaker cables and power cables will bring obvious improvements in clarity, detail and resolution to your high-end entertainment system.
The Dark Field Elevator's lightweight, flexible structure makes them easy to use and place in a system. Whether behind a crowded rack system, tipped sideways on a shelf or suspended in between two cables -- Dark Field Elevators provide impressive performance at an attractive price.
