The Radial USB-Pro is a premium stereo DI designed to connect laptops, tablets, and other USB-equipped devices directly to professional PA systems and recording consoles. Ideal for live performances, conferences, or studio work, it delivers pristine audio quality while eliminating ground loops and noise, ensuring your digital audio always sounds its best.

Key Features

• High‑performance 24‑bit / 96 kHz digital‑to‑analog conversion for superb audio clarity.
• Balanced stereo XLR male outputs (2 ×) which feed directly into a mixer, PA system or powered speakers — ensuring long cable runs without hum or noise.
• USB Type‑B connection to the laptop — driver‑free, automatic recognition across major OSes (Windows, Mac) making it truly plug & play.
• Headphone output (3.5 mm) on the front panel for monitoring the signal before it goes live.
• Level control on front panel to adjust the output volume easily.
• Mono summing switch — useful when you need to collapse stereo to one channel (e.g., FOH systems).
• Ground‑lift switch and optional onboard isolation transformers to eliminate hum, buzz and ground‑loop issues in complex live / AV environments.
• Built for the road: Rugged steel construction, non‑slip pad underneath, and “book‑end” design that protects connectors and switches.
