FI-48M NCF (R) Wall Plug

Sleek, smooth and sweet sounding, 40 series connectors leverage much of the technology from Furutech's top-line 50 series, including Alpha copper, Rhodium plating and NCF materials. To keep the price down, these connectors are slightly lower mass and don't have the exotic carbon fiber treatments of their big brothers.

The Furutech Floating Field Damper System
Magnetic Floating Field Damping Current flowing through a cable and its connector creates magnetic (and electrostatic) fields around them, building and collapsing 60 times per second in 120VAC systems. This magnetic field induces current flow– electrical potential–in small parts like the screws holding the connector shell together which have to be metal for tight clamping. The current flow in these small parts actually creates “floating” magnetic fields around them, and they interfere with the cable/connector’s larger surrounding magnetic field resulting in noise and distortion. 

The Furutech Floating Field Damper solves the biggest problem you never realized you had by star grounding the metal parts in which floating magnetic fields are induced by current flow. All the various metal parts of the connector are tied together and shunt whatever electrical potentials generated to ground. This significantly lowers noise by reducing distortion for ultra-clean and stable power transfer.

Nano Crystal Formula (aka NCF) 
This is the ultimate electrical and mechanical damping material. Developed by Furutech, NCF is a proprietary crystalline compound blended with ceramic nanoparticles and carbon powder. This process creates a remarkable material with multiple benefits: First, NCF generates negative ions to eliminate static charge build-up. Second, NCF converts thermal energy into far-infrared light, a remarkable innovation allowing the material to run cooler, even during the most demanding of passages. Third, NCF has excellent damping properties, thanks to the “piezoelectric effect” of the NCF material. Found exclusively in Furutech’s top offerings, NCF is a game-changing material and its sonic effect is undeniable; superior resolution, clarity and dynamics, with deep-black backgrounds and a purely natural tonal balance.
