Nordost Norse 2 Series Frey 2 USB-C Adapter

Reference USB-C Interface Adaptation | Available at Trimira Audio The Nordost Frey 2 USB-C Adapter is a compact USB-C-to-USB-A adapter within Nordost's Norse 2 Series, designed to connect modern USB-C source devices to established USB Type-A cables and compatible digital-audio equipment. Rather than functioning as a simple passive plug, the adapter uses a short mechanically controlled cable section incorporating Nordost's Dual Mono-Filament technology, silver-plated solid-core OFC conductors, controlled USB geometry, comprehensive shielding, and gold-plated connectors. At Trimira Audio, we recommend the Frey 2 USB-C Adapter for systems where a USB-C source needs to connect to an existing high-performance USB-A cable or USB-A interface. Key Features & Technological Innovations Patented Dual Mono-Filament Technology The conductors are wrapped with two helical FEP strands before being enclosed in an extruded FEP outer jacket. This creates a low-contact dielectric environment designed to minimize dielectric interaction and energy storage while supporting rapid signal propagation. Silver-Plated Solid-Core OFC Conductors The adapter employs silver-plated solid-core 99.99999% high-purity OFC copper conductors. The solid-core architecture provides consistent conductor geometry within the short adapter cable section. Controlled USB Impedance Architecture The short cable section is mechanically controlled to maintain the electrical characteristics required for USB data transmission across the USB-C-to-USB-A connection. 100% Dual-Layer Shielding A combined foil-and-braid shielding structure provides 100% total coverage, helping protect the USB connection from: RF interference Electromagnetic interference External electrical noise USB power-line noise High-frequency crosstalk Gold-Plated USB Terminations The adapter uses: USB Type-C male connector USB Type-A female connector This allows a USB-C source to connect to an existing USB Type-A cable without replacing the entire cable assembly.
