Firebird High (Variable) Current

The AudioQuest FireBird High (Variable) Current is a high-current mains power cable designed for use with AC power conditioners and regenerators, power amplifiers and components with a built-in power amplifier. Suitable equipment includes AV receivers, powered speakers and powered subwoofers.

FireBird uses solid Perfect-Surface Silver (PSS) and Perfect-Surface Copper+ (PSC+) conductors. Solid conductors prevent electrical strand-to-strand interaction, which is a major source of distortion. The surface quality of a conductor is important because it guides the fields within the conductor and the magnetic fields extending outside it. The sizes of the PSS and PSC+ conductors are selected so that FireBird’s performance approaches an all-PSS Silver design at a lower cost.

High (Variable) Current Cables

With a current capacity of 20 amps RMS @ 125VAC 50/60Hz and 16 amps RMS @ 220-240VA 50/60Hz, AudioQuest FireBird High (Variable) Current can withstand transient current peaks many times its continuous average RMS rating. It is suitable for AC power conditioners, power regenerators, AC isolation transformers and AC battery back-up devices, as well as power amplifiers, powered subwoofers, powered loudspeakers, powered receivers and integrated amplifiers.

ZERO-Tech

ZERO-Tech removes the characteristic impedance associated with traditional cable geometry, allowing current to be delivered without the restriction of a cable impedance mismatch.

RF/ND-Tech

AC ground wires can protect against an electrical short circuit, but they can also act as antennas and become subject to induced radio-frequency noise. This RF noise can bypass component power supplies and couple directly into sensitive audio and video circuits. AudioQuest’s RF/ND-Tech reduces this distortion across a wide range of radio frequencies. Its circuit topology combines a common-mode phase-cancelling array with proprietary dielectric materials that provide additional differential linear filtering. US Patent # 8,988,168.

72v Dielectric-Bias System (DBS)

The insulation also acts as a dielectric and can function as a shunt filter. Biasing minimises dielectric noise and linearises the filter, improving wide-bandwidth dissipation of induced RF noise.

Directionality

All drawn metal strands and conductors have a non-symmetrical, directional grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from areas where it could cause distortion. The correct direction is determined by listening to every batch of metal conductors used in each AudioQuest audio cable. Where applicable, arrows are marked on the connectors. On most AudioQuest cable models, the arrows indicate both the direction that optimises metal directionality as part of the noise-dissipation system and the non-symmetrical attachment of the shield and ground for full-system performance.
