Radial SW8-USB

USB Interface and Auto-Switcher


About this item



The Radial SW8-USB is a streamlined solution for employing redundant playback systems on stage, with dual USB inputs that allow you to connect directly to your primary and backup computers, providing eight channels of high-quality audio and peace of mind during a live performance.

  • Switch between redundant playback systems
  • Two USB inputs eliminate the need for additional audio interfaces
  • Manual or seamless automatic switching
  • Line-level or transformer-isolated mic level outputs
  • Synchronize both playback systems using MTC

The all-in-one backing track solution

The SW8-USB is the complete solution for performances that utilize redundant playback systems for backing tracks, combining two built-in high-performance USB interfaces with an auto-switching feature that detects dropouts and effortlessly switches to the backup computer in an instant. Dual USB inputs with separate 24bit/192kHz converters allow two computers to be connected in tandem, so digital workstations on both machines can connect to the SW8-USB as an audio and MIDI interface. Start/stop synchronization is also possible between both computers through MTC, ensuring flawless switching between playback rigs with less equipment than ever.
