Viablue NF-75 Digital Coax (RCA) Cable

The VIABLUE™ NF-75 Digital Coax (RCA) Cable is engineered for exact signal integrity over short or extended distances. Designed for S/PDIF transmission, this coaxial digital cable maintains a consistent 75-ohm impedance and uses silvered OFC shielding to eliminate signal loss and jitter. From source to DAC, the NF-75 ensures your digital audio signal remains clean, stable, and uncolored.

Key Features

• True 75-ohm impedance: Ideal for S/PDIF digital audio transmission
• Silver-plated OFC shielding: Dual-layer Silver Shield prevents interference
• Polyethylene foam dielectric: Maintains geometry and minimizes signal loss
• Ferrite filter 9: Suppresses high-frequency EMI for clean transmission
• Gold-plated VIABLUE™ T8 RCA plugs: 24k gold contacts for perfect pressure and signal transfer
• Cobra braided sleeving: Durable and flexible with a premium finish
• Handmade in Germany: Assembled and tested by VIABLUE™ technicians for flawless execution

Precision Engineering for Digital Audio

The NF-75 is designed to support the precision requirements of digital coax transmission. It uses a core made from seven strands of tinned OFC copper, surrounded by a polyethylene foam dielectric to maintain impedance and minimize timing errors. This results in a stable signal path that preserves audio resolution and spatial accuracy.

VIABLUE™ Silver Shield Architecture

To eliminate distortion and maintain complete shielding, the NF-75 is equipped with the proprietary VIABLUE™ Silver Shield. This shielding system combines a tightly woven silvered OFC copper braid with an ALU-PET foil layer to block external noise from entering the signal path.

Ferrite Filtering for Signal Purity

A VIABLUE™ Ferrite Filter 9 is built into every NF-75 cable, encased in a full-metal housing. This filter reduces electromagnetic interference commonly found in high-frequency environments, helping preserve signal integrity especially between digital transports and DACs.

Made in Germany

All VIABLUE™ cables are manually produced and assembled in Germany using in-house engineered components. This ensures flawless quality control, exceptional performance, and a product that stands the test of time.
