Radial Engineering USB-Pro

The USB-Pro, from Radial, is a stereo DI box designed for the purposes of converting audio files sourced from a laptop or desktop and transfer them to a pair of outputs that can be fed to a PA, broadcast, or recording console.

One of the best aspects of the USB-Pro is its inherent ease-of-use. Simply connect it to a compatible device for instantaneous use. Once connected, the unit will automatically configure itself no matter the operating system used, effectively negating the need for tedious drivers. Even better, the USB-Pro features 24-bit/96kHz stereo connectors for enhanced detail and ample headroom, meaning users will not require additional sound cards or converters in order to transfer files.
