Furutech FI-11(Cu) – High Performance IEC Connector Non Plated Copper

The normal cable diameter the FI-11 series connectors will accept is 6.6mm to 16mm. With the Furutech FI-11 Series Longer Screws you can use larger diameter cable up to 20mm.

Furutech is justifiably proud of its reputation for engineering, build-quality and performance, and have won the loyal support of audio enthusiasts worldwide for their finely made and beautiful sounding cables and audio accessories.  Furutech performance is legendary in the hi-fi industry, and they continue to bring exceptional products to the market that are carefully engineered to guarantee the best sound per pound.

Using Furutech’s patented alpha cryogenic process and demagnetising of all contact pins, this connector is a reference product due to the company’s attention to engineering and manufacturing detail. Adding Furutech’s FI-11Cu high performance IEC connector to your mains power cord will bring sonic benefits to your system for a relatively small outlay. This IEC will accept ultra-thick gauge cables and is easy to install.

Furutech’s FI-11 series connectors are arguably the best bang for the buck IEC connectors on the market, and will accept larger O.D. cabling (up to 16mm). They are very easy to work with, require no soldering, and will accept up to two 12 AWG wires per terminal. The electrical contacts’ base metal is phosphor bronze, and platings available are copper, gold and silver.THis connector also includes Furutech’s special “ground jumper” system that connects the screws to the safety ground, thus eliminating magnetic interactions. Their clamping mechanism allows superior clamping pressure on the wires, and their cable body clamp is extremely well designed. Mate these with Furutech’s 15A male power plugs for ultimate performance. Available in three plating schemes: FI-11Cu (copper), FI-11G (gold), and FI-11Ag (silver).

The C15 female connector has the same pin array as a C13. However the C15 has a notch at the base. The C15 can be plugged into the C14 or C16 inlets.

ALL metallic parts used in Furutech products go through the Alpha Process treatment to keep all connectors, conductors, and metal parts in a perfect stress-free, stable and highly conductive state.

The treatment begins during the manufacturing process with a deep, conditioning cryogenic freeze of all metal parts. Using high-end refrigerants — liquid N2 or He
– Furutech achieves temperatures of between -196 to -250C. The treated parts actually change their molecular structure at these extremes of temperature relieving internal stress. The molecules bond together more tightly and the overall structure becomes more stable. This improves electrical conductivity and so power and signal transfer.

Step two in the Alpha Process exposes these same parts to the patented Ring Demagnetization treatment. Ordinary high power magnets used for this purpose often increase magnetization effects; they leave some areas more magnetized than others. Just like a CD spinning over a fixed magnet; when the CD stops the area above the magnet is still exposed to the magnetic field causing audible effects. This patented process uses controlled attenuation to completely eliminate magnetization for immediately more vivid and colorful improvements. Ring Demagnetization further enhances conductivity of all treated materials. The patent holder for this treatment is Sekiguchi Machine Sale Co., Ltd. in Japan; Furutech are licensed users of the technology.

The Final Result The 2-Step Alpha Cryogenic and Demagnetizing Process works in tandem with other design-in features to create the most optimized power and signal transfer possible.  Furutech’s total awareness and devotion to detail results in a greater sense of power, dynamics, and resolution, with cleaner, blacker backgrounds and a larger, more stable soundstage, vivid tonal colors and deeper extension at both ends of the frequency range.
