Furutech FT-111 (R) / (G) High-End RCA Connector for Superior Signal Integrity
The Furutech FT-111 (R) / (G) RCA connectors are engineered with advanced materials and precise manufacturing techniques to deliver uncompromising audio signal transmission. These connectors, ideal for both professional and audiophile-grade cable terminations, incorporate Furutech’s α (Alpha) Pure Copper conductors, state-of-the-art insulation, and non-magnetic stainless steel components for enhanced durability, signal fidelity, and ease of installation.
FT-111 (R): Rhodium-Plated for High-Fidelity Signal Transmission
The FT-111 (R) is equipped with a one-piece Rhodium-plated α (Alpha) Pure Copper conductor, which is designed to minimise impedance and ensure ultra-low signal loss. Rhodium, known for its exceptional hardness and oxidation resistance, delivers a transparent, uncoloured sound with precise transients and superior high-frequency extension. This makes the FT-111 (R) ideal for high-resolution audio systems that demand the highest levels of neutrality and detail retrieval.
Key Technical Features of the FT-111 (R):
- Low-Mass Signal Path: The one-piece Rhodium-plated pure copper conductor minimises material density in the signal path, reducing distortion caused by eddy currents and preserving signal purity.
- Non-Magnetic Stainless Steel Housing: The connector's body and end ring are made from non-magnetic SUS stainless steel, which minimises electromagnetic interference (EMI) and protects against mechanical resonance.
- POM Resin Insulation: The injection-moulded Polyoxymethylene (POM) insulation body features high dielectric properties, ensuring signal integrity while preventing electrical leakage and mechanical vibration transfer.
- Solder-Free Termination: Furutech’s set screw connection eliminates the need for soldering, enabling a cold-weld-like connection for minimal resistance and easier assembly.
FT-111 (G): Gold-Plated Conductors for Rich, Warm Sonic Signatures
The FT-111 (G) features 24K Gold-plated α (Alpha) Pure Copper conductors, offering the excellent conductivity of Furutech’s Alpha-treated copper combined with the warm, full-bodied tonality of gold plating. This configuration is optimised for listeners who prefer a richer harmonic presentation, delivering smooth midrange textures and an inviting low-frequency response.
Key Technical Features of the FT-111 (G):
- Gold-Plated α (Alpha) Copper Conductors: The gold plating enhances durability and provides a slightly warmer tonal character, without compromising on low-impedance performance.
- Injection-Moulded Conductors: Both the positive and negative polarity conductors are moulded in POM resin, which enhances mechanical stability and reduces vibration transmission.
- Superior Contact Integrity: Gold plating resists oxidation and improves surface contact with RCA sockets, maintaining signal consistency over time.
- Non-Resonant Housing: The same non-magnetic stainless steel housing found in the FT-111 (R) ensures mechanical damping and EMI protection for stable, interference-free signal flow.
Material Science and Construction
The Furutech FT-111 (R) and FT-111 (G) connectors are a testament to Furutech’s rigorous approach to materials optimisation. The proprietary α (Alpha) Process, which involves cryogenic treatment and demagnetisation, ensures that the pure copper conductors achieve maximum conductivity while minimising internal stress and impurities.
Both connectors are designed with precision-machined housings, injection-moulded insulation, and a set screw termination system, allowing for robust mechanical connections without requiring heat from soldering. This reduces stress on the cable conductor and ensures long-term reliability.
Construction Overview:
- Conductor Materials:
- Housing: Non-magnetic SUS stainless steel for EMI rejection and resonance damping.
- Insulation: Black POM resin for high dielectric strength and vibration resistance.
- Termination System: Screw-secured, solder-free assembly for quick and reliable cable terminations.
- End Ring: Non-magnetic stainless steel for enhanced durability and strain relief.
Precision Engineering for Compatibility and Performance
The FT-111 connectors are designed to accommodate core insulation diameters up to 10.0mm, making them compatible with a wide range of premium cables. The compact yet robust construction ensures seamless integration into professional audio setups, while the locking collet design guarantees a secure and vibration-free connection to RCA sockets.
Dimensions:
- Housing Diameter: 14.0mm
- Housing Length: 26.5mm
- Overall Length: Approximately 50.6mm
This precision-engineered profile allows the connectors to be used in tight installation spaces without compromising performance or ease of handling.
Advanced Connector Design Eliminates Signal Loss
Furutech’s attention to detail in the FT-111 series ensures minimal signal degradation across the entire audio frequency range. By reducing contact resistance and using high-purity, cryogenically treated materials, the connectors deliver a distortion-free, noise-free signal. The result is an audio performance characterised by exceptional clarity, dynamic range, and spatial accuracy.
Both Rhodium and Gold options exhibit ultra-low impedance, while the POM resin insulation and non-magnetic housings eliminate capacitive coupling and eddy currents. This technical optimisation makes the FT-111 series connectors the perfect choice for applications ranging from audiophile-grade home systems to professional-grade studio monitoring.
High-Performance Meets Usability
Designed with convenience in mind, the Furutech FT-111 connectors require no soldering for termination, making them accessible to professionals and hobbyists alike. The set screw mechanism ensures a firm grip on the cable conductor, reducing termination time while maintaining a secure and durable connection.
The premium build quality and elegant design of the FT-111 (R) and (G) also make them an attractive choice for custom cable projects. Whether you’re upgrading existing interconnects or creating bespoke solutions, these connectors provide a professional-grade finish with unmatched performance.
