Sweetwater and MOTU have enjoyed a long-standing relationship, due to MOTU's products offering our customers superb sound and solid performance. 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.

Loopback functionality makes live internet streaming easy

If you do live streaming or podcasting, you’ll appreciate the MOTU M4’s loopback functionality. Loopback blends your mic or other input signals with the output from your computer, then sends the blended signal back to your computer. This enables you to record your computer’s output, along with the inputted material. The M4 also includes a mix knob for balancing your live input with your computer’s playback.

Hardware monitoring offers zero-latency operation
