Behringer CU1A Ultra-Low Latency 2-In/2-Out USB Audio Interface for Eurorack

The Behringer CU1A is a compact USB audio interface module designed to integrate Eurorack modular systems directly with computer-based recording environments. With ultra-low latency performance and high-resolution 48 kHz converters, it provides reliable audio capture and playback for modular synthesizer setups.

Designed for simplicity and efficiency, the CU1A connects to your computer via USB Type-C and operates as a class-compliant device, requiring no additional drivers for most modern Windows and macOS systems. This allows seamless integration with digital audio workstations for recording, monitoring, and processing modular audio signals.

The module features stereo analog inputs and outputs via 3.5 mm connectors, allowing flexible routing between your Eurorack system and external recording setups. A dedicated headphone output with independent level control provides convenient monitoring of both incoming and outgoing audio signals.

Because the CU1A is powered directly via USB Type-C, it does not draw power from your Eurorack case, helping preserve available current for other modules in your system. With its compact footprint and straightforward connectivity, the CU1A is a practical solution for bringing modular synth performances into the digital production workflow.
