Your Streamlined Backing Track Solution

Combining two high-performance USB audio interfaces with an auto-switching feature that detects dropouts and effortlessly switches to the backup computer in an instant, the Radial SW8-USB is your complete, streamlined solution for performances that employ redundant playback systems for backing tracks. Dual USB ports allow you to connect directly to your primary and backup MacOS computers, providing eight channels of high-quality audio (as well as peace of mind) during a live performance and eliminating the need for additional audio interfaces. Performers and FOH engineers at Sweetwater checked out the Radial SW8-USB and said, "Where has this been all my life?" You'll have the same reaction.

High-quality audio and peace of mind

The SW8-USB's dual USB inputs with separate 24-bit/192kHz converters let you connect two computers in tandem, letting DAWs on both machines utilize the SW8-USB as an audio/MIDI interface. Start/stop synchronization is also possible between both computers via MTC, ensuring seamless switching between playback rigs with a minimum of equipment. Simply connect the balanced 1/4" analog outs to the PA system and engage the auto-switch mode, and the SW8-USB will switch instantly to the backup system in the event of an error. An optional Radial JR-2 footswitch may be employed to manually switch between inputs or to put the SW8-USB into standby mode between songs.

Radial SW8-USB Dual-USB Auto-switcher and Interface Features:

  • Easily switch between redundant playback systems
  • 2 USB ports with 24-bit/192kHz converters eliminate the need for additional audio interface

Reviews

Simply the BEST
Radial makes amazing gear. You can literally feel it when you hold it in your hands. The build quality is superior. 100% worth the price you pay for it.

I've had several of these units on the road with tours since before COVID (that's 3 solid touring years, plus the storage time during the lockdowns). Not a single one of them (or any other piece of Radial gear) has failed a single time in all of those years of storage and road use. It pays for itself in Peace of Mind alone.

Anyway, it is the best option for what it is. You get what you pay for!

when it works it's great
it'a a great concept but it occasionally loses audio contact with the host computer causing you to have to switch...kind of unacceptable in a so called pro audio interface.. hoping that Radial will address this.. as it's a fantastic idea for hardware
