MOTU M4 4x4 USB-C Low-Latency Audio Interface

MOTU M4 USB-C Audio Interface — Pro-Level Recording with Expanded I/O and Metering

The MOTU M4 USB-C Audio Interface builds on the success of the M2 by offering enhanced connectivity and monitoring options while retaining the same award-winning ESS Sabre32 Ultra™ DAC technology. With 120 dB dynamic range on its outputs and ultra-low latency performance, the M4 ensures your recordings and monitoring are studio-grade—whether you're at home or on the move.

Expanded I/O for Greater Flexibility

Designed for producers and musicians who need more connections, the M4 offers 4-in/4-out I/O, including two front-panel XLR/TRS combo inputs, plus two rear balanced line inputs and outputs. It’s perfect for stereo synths, drum machines, and multi-instrument setups without needing a mixer.

Full-Colour Metering on All Inputs and Outputs

A standout feature is the high-resolution full-colour LCD, giving you real-time input and output level metering—something rarely found at this price point. Visual clarity helps you dial in perfect levels and avoid clipping during sessions.

Crystal-Clear Monitoring and Fast Workflow

With ultra-low latency (as low as 2.5ms round-trip), the M4 ensures accurate real-time monitoring. The direct monitoring mix knob lets you blend input and computer playback for zero-latency recording, ideal for vocalists and instrumentalists.

Cross-Platform and Bus-Powered Convenience

The M4 is class compliant for plug-and-play operation with macOS and iOS devices, and includes a driver for Windows systems to unlock full performance. It’s also USB bus-powered, reducing cable clutter and making it ideal for mobile use.
