USB Laptop Direct Box

The 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 analog outputs.

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. Designed for plug-and-play simplicity, only a standard USB Type-B cable (sold separately) is required to connect your laptop and the USB-Pro. It requires no proprietary drivers to operate. Once connected, 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, and transport audio via 24bit/96kHz digital-to-analog converters to ensure signal quality is maintained. 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.
