Nordost Tyr 3 Analog Interconnects

Eight silver-plated conductors, Dual Mono-Filament construction, and individually shielded twisted pairs

The Tyr 3 is the flagship analog interconnect in Nordost’s Norse 3 Series, positioned above Heimdall 3 and Frey 3. It brings together technologies developed through the company’s work on its Reference and Supreme Reference cables, combining conductor isolation, mechanical tuning, and dual shielding.

Eight 24 AWG silver-plated, solid-core oxygen-free copper conductors are arranged in four twisted pairs. This geometry, originally developed for Nordost’s tonearm cables, maintains consistent spacing between conductors to help reduce electromagnetic interference and crosstalk. Nordost’s proprietary Dual Mono-Filament construction creates a virtual air dielectric around each conductor, while mechanically tuned conductor lengths address resonance behavior.

Two Layers of Shielding

Each twisted pair is individually shielded, with a second braided shield providing 97% overall coverage. This arrangement helps protect low-level analog signals from interference. The Tyr 3 is available with gold-plated Neutrik XLR connectors for balanced connections or Neutrik Profi RCA connectors for single-ended connections.
