Connect your laptop to a pro audio system
Whether you are playing backing tracks on stage, giving an audio presentation, or performing the role of DJ at an event, the USB-Pro is the easiest way to provide a high quality noise-free connection between a laptop and any sound system. Made for plug and play simplicity, the USB-Pro will automatically be listed as an available sound card in the audio settings of all popular operating systems including Windows and Mac, with 24bit/96kHz digital to analog converters that retain the quality of the audio signal. A stereo pair of balanced XLR outputs allows you to connect to a microphone preamplifier, PA system, mixing console, or even a powered speaker, with an on-board level control for quick and easy volume adjustments. Should any noise be encountered, ground lift switches are provided and isolation transformers can be inserted into the signal path to eliminate hum and buzz from ground loops, for a clean connection to the PA.

"Sometimes I think Radial Engineering is in the business of inventing cool new gizmos to solve problems you didn't know you had... or that you knew you had but didn't know there was a fix for. Here's another example: Radial's first ever digital audio product, the USB-Pro..."
"I acquired a Radial USB Pro to use on the CX Roadshow because I needed an audio interface to sit between my laptop and a mixing console for an audio demo. People tend to examine my demo setups pretty critically, and for that reason the USB Pro was good. I've never seen anyone look at a Radial box and question it."
"My biggest regret is not finding out about Radial Engineering direct boxes sooner! We have transitioned through our move to individual monitor mixes from FOH, to a dedicated monitor console, to personal mixers and the Radial direct boxes have continued to work flawlessly through all of our upgrades."
