USB Laptop Direct Box
Radial - USB-Pro
Connect your laptop to a pro audio systemThe Radial USB-Pro is a high-resolution stereo digital audio converter and direct box that is designed to connect to any computer and seamlessly convert digital audio tracks to a pair of balanced analogue outputs. If you're 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.
Designed 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. If any noise occurs, ground lift switches are available and isolation transformers can be inserted into the signal path to remove hum and buzz from ground loops, for a clean connection to the PA.
