    • Direct Bypass Path: Pure passive balanced connection with no active circuitry.
  • Sends the selected signal to the Rega Osiris balanced XLR input.
  • Ground Lift Switch – uDisconnects Pin 1 XLR Ground)

Design Features

  • 100% passive audio routing
  • No power supply required
  • No relays or active electronics in the signal path
  • Gold-plated switch contacts
  • Full balanced XLR signal integrity maintained on the bypass path
  • Excellent common-mode noise rejection throughout the balanced signal chain
  • Minimal insertion loss
