This high-resolution stereo digital audio converter (DAC) is designed for professional musicians, DJs, and audio engineers who demand the highest quality sound. Perfectly suited for seamless integration with any computer system, this used but like-new condition product offers an unbeatable blend of functionality, performance, and rugged durability.

With the Radial USB-PRO, transferring digital audio to analog has never been easier. Simply connect your computer through a standard USB type-B port, and the USB-Pro will automatically be listed as an available sound card in your audio settings, regardless if you are using Windows XP, Windows 7/8, or Mac OSX. The device comes equipped with a stereo pair of balanced XLR audio outputs with adjustable levels for feeding signals to various audio systems such as microphone preamplifiers, PA systems, mixing consoles, and powered speakers. Additionally, you can monitor digital-to-analog conversion through the 3.5mm headphone output to ensure your signal quality and levels are optimum before full amplification.

Designed to withstand the rigors of professional touring, the USB-Pro features Radial’s signature book-end design, safeguarding crucial switches, connectors, and controls. Inside, a robust I-beam construction prevents the internal PC board from torquing, ensuring long-term durability and reliability. Ground loops causing hum or buzz? A simple flip of the recessed side-access switches allows for the insertion of isolation transformers into the signal path, augmented further by a ground lift switch.
