Radial Engineering SW8-USB - Auto-Switcher and USB Interface

The Radial SW8-USB is a professional 8-channel USB audio interface and redundant playback switcher designed for critical live performance environments. It allows two computers to run simultaneously as primary and backup systems, automatically switching if the main system fails to ensure uninterrupted audio playback during live shows.

Built for touring engineers, playback operators, and large-scale productions, the SW8-USB combines high-quality digital audio conversion with robust redundancy control. It supports up to 24-bit / 192 kHz audio, delivering low-latency, high-fidelity performance suitable for demanding live playback and backing track systems.

In addition to dual USB connectivity, the SW8-USB offers flexible analogue output options including transformer-isolated XLR, TRS, and DB25 connections for seamless integration into professional PA, monitor, and broadcast systems. MIDI and MTC synchronisation ensure both computers remain locked in time for reliable playback alignment.

Housed in a rugged 1U rackmount chassis, the SW8-USB is built for touring durability and mission-critical reliability in live performance environments where failure is not an option.
