The Behringer X-USB is a specialized 32-channel expansion card designed exclusively for the Behringer X32 digital mixing console, transforming the mixer into a high-performance USB 2.0 audio interface for professional studio and live recording applications. This card provides bidirectional 32-in, 32-out audio streaming at 24-bit resolution, allowing engineers to multitrack live performances directly to a computer or playback pre-recorded tracks through the console for virtual soundchecks without requiring the band to be present. The integration is seamless with any DAW software, supporting both ASIO drivers for Windows systems with ultra-low latency performance and Core Audio on Mac OS for native compatibility.

Beyond simple audio streaming, the X-USB card adds significant production versatility to the X32 ecosystem. It enables the use of computer-based plug-ins as outboard effects processors during live shows, expanding the console's processing capabilities without additional hardware. The card also provides HUI and Mackie Control emulation, allowing the X32 faders and controls to remotely operate compatible DAW software for enhanced workflow efficiency.

Engineered and developed in Germany, the X-USB card occupies the standard expansion slot on X32 series consoles, including the X32, X32 Compact, X32 Producer, X32 Rack, and X32 Core. The card requires a computer with a USB 2.0 port and meets modest system requirements: Windows users need a Core 2 Duo processor at 2 GHz with 1 GB RAM, while Mac users require a 1.5 GHz processor with 512 MB RAM. The X-USB is a fundamental expansion card that has been standard in many X32 consoles for years, with the X-LIVE card serving as an alternative option that adds dual SD/SDHC recording slots for laptop-free multitrack capture.
