Flagship USB Digital Audio Transmission in the Norse 2 Series | Available at Trimira Audio
The Nordost Tyr 2 USB 2.0 Cable represents the flagship USB cable within Nordost's Norse 2 Series, designed for demanding computer-audio systems, dedicated music servers, USB interfaces, and high-resolution DACs.
Combining Dual Mono-Filament technology, 20 AWG silver-plated solid-core OFC conductors, controlled USB data geometry, comprehensive shielding, and precision gold-plated termination, Tyr 2 provides a carefully engineered physical connection for high-speed USB digital audio.
At Trimira Audio, we recommend the Tyr 2 USB 2.0 Cable for reference-oriented computer-audio systems seeking the highest-performance USB connection within the Norse 2 range.
Key Features & Technological Innovations
Patented Dual Mono-Filament Technology
Each conductor is 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.
Four 20 AWG Silver-Plated Solid-Core OFC Conductors
Tyr 2 employs 4 × 20 AWG solid-core conductors manufactured from 99.99999% high-purity OFC copper with pure silver plating.
The heavy-gauge solid-core construction provides consistent conductor geometry and substantial current-carrying capability.
Controlled 90-Ohm USB Data Geometry
The USB data conductors use mechanically controlled twisted-pair geometry designed around the 90-ohm characteristic impedance required by the USB high-speed data interface.
This helps maintain consistent electrical characteristics along the high-frequency data path.
100% Dual-Layer Shielding
A combined foil-and-braid structure provides 100% total coverage, helping isolate the USB signal path from:
- RF interference
- Electromagnetic interference
- External electrical noise
- High-frequency crosstalk
- Internal USB power-line noise
Custom Gold-Plated Terminations
Tyr 2 USB 2.0 is available with custom gold-plated connectors in:
- USB Type-A → Type-B
- USB Type-A → Micro-B
These configurations accommodate common computer-to-DAC and computer-to-USB-device applications.
