Description
The Radial USB-Pro solves a common studio and stage headache: getting clean audio out of a computer and into professional gear without hiss, hum, or a pile of adapters. It’s a stereo USB DAC and direct box in one, converting digital audio straight to balanced XLR outputs that plug right into a mic preamp, mixing console, or powered speaker.
- Plug-and-play — shows up automatically as a sound card on Windows XP, Windows 7/8, and Mac OSX, no driver install needed
- 24-bit digital-to-analog conversion, 24/96 sample rate capable, for accurate, full-bandwidth playback
- 3.5mm headphone output lets you monitor signal quality before it ever hits the PA
- Mono-sum switch for checking phase or feeding a mono system
- Two side-access switches insert isolation transformers to kill ground-loop hum and buzz
- Ground lift switch pulls pin-1 on both XLR outs for extra noise rejection
Built like every other Radial box, the USB-Pro is meant to survive real-world use, not just sit on a desk. The book-end chassis shields switches and connectors from impact, I-beam internal construction keeps the PC board from flexing under stress, and a full no-slip bottom pad isolates it mechanically and electrically for quiet, stable operation.
Whether you’re feeding a laptop’s audio into a mixing console at a gig, transferring client files to a recording system at full sample rate in the studio, or running sound for a video presentation where ground loops usually wreck the audio, the USB-Pro handles it with one cable and a couple of switches — no fuss, no extra gear.
This unit is B-Stock: fully functional and ready to work, offered at a lower price point.
