RF/ND-Tech (Patented Radio-Frequency Ground-Noise Drain)

Minimizes Circuit Misbehavior by Suppressing Induced RF NoiseUS Patent # 8,988,168. AC grounding wires can provide protection against electrical shorts, but they also act as antennas. As a result, they are susceptible to induced radio frequency (RF) noise. This RF noise bypasses the power supplies of the components and is typically directly coupled to the most sensitive audio/video circuits of a system. AudioQuest's patented RF/ND-Tech significantly reduces this distortion, resulting in unprecedented levels of noise reduction across the widest possible bandwidth (range) of radio frequencies. Our unique circuit topology utilizes a common-mode phase-cancellation array, combined with proprietary dielectric materials that provide additional differential linear filtering.

Pure, True-Concentric Perfect-Surface Silver and Perfect-Surface Copper+ Conductors

The superior geometry of metals and conductors significantly reduces the ear-disturbing distortion caused by Transient Intermodulation (TIM). Silver Cloud utilizes a carefully engineered combination of Perfect-Surface Silver (PSS) and Perfect-Surface Copper+ (PSC+).

72v Dielectric Bias System with CARBON-level radio frequency drop (DBS).

All insulation is also a dielectric, whose electrical properties affect the integrity of the signal. When the insulation is insensitive, the dielectric influence (absorption and non-linear release of energy back into the signal flow) causes a varying amount of time delay (phase shift) for different frequencies and energy levels, which is a significant issue for highly time-sensitive multi-octave audio. AudioQuest's multi-patented DBS creates a strong, stable electrostatic field that saturates and polarizes (orders) the molecules of the insulation. This minimizes non-linear time delays, resulting in clearer sound emerging from a "weaker" background. The inclusion of an RF Trap (a technology developed for AudioQuest's Niagara series power products) in the DBS battery holder provides further reduction of radio frequency noise. The DBS battery packs last for many years. A test button and LED allow for periodic battery checking.
