MOTU M4 4x4 USB-C Audio Interface

The M4 follows suit, packing top-notch sound, impressively low latency, and ample I/O into a single-rack enclosure. Renowned ESS Sabre32 Ultra DAC technology delivers 120dB of dynamic range, ensuring that the M4's analog audio quality can hang with the most impressive gear on the market. Optimized drivers yield round-trip latency as low as 2.5ms at 24-bit/96kHz with a 32 sample buffer. The M4 includes all of the essential connections, including two mic preamps, four DC-coupled analog outputs, and an ESS-driven stereo headphone output. MIDI I/O is also included.

Hardware monitoring offers zero-latency operation

Latency can really take the mojo out of a performance — it’s a jarring sensation. That’s why the M4 includes 1-touch hardware monitoring. This feature enables all of the interface’s analog inputs to be routed directly to its analog outputs, resulting in zero-latency operation. This means that there is no delay between what you play and/or sing and what you hear in your headphones. The M4’s inputs can also be recorded simultaneously, allowing you to monitor with zero latency while tracking — a must for achieving a natural-sounding performance.
