Speed: The M4 provides best-in-class speed for monitoring live inputs (mic, guitar, or keyboard) through your computer, thanks to MOTU's expertly engineered USB drivers, which deliver class-leading, ultra-low 2.5 ms Round Trip Latency (at 96 kHz with a 32 sample buffer)

Metering: When recording and mixing, nothing is more critical than achieving optimum levels. The M4 is the only audio interface in its class with a full-color LCD featuring clear, detailed level meters for all inputs and outputs. Enjoy professional-level volume control and feedback to get your sound just right

Loopback: The driver provides convenient loopback channels to your host computer, so you can easily route computer output back to the computer, where you can mix it with live mics and/or guitar inputs from the M4 in your host software for live streaming or podcasting. Streaming and podcasting have never been easier and better-sounding

A Tradition of Engineering Excellence: Decades of award-winning product engineering for hit songs, mega tours, primetime shows, and blockbuster movies goes into every MOTU audio interface
