Record vocals, instruments, or other audio sources quickly and easily. The M4 includes MOTU Performer Lite and Ableton Live Lite production software, 100+ instruments, dozens of plug-ins, and over 6 GB of loops and samples to start making music right away. Additional features include two mic/line/hi-Z instrument XLR combo inputs, individual preamp gain and 48V phantom power, two balanced 1/4-inch line inputs, one-touch hardware monitoring for all inputs, support for stereo monitoring, four balanced 1/4-inch DC-coupled outputs, four unbalanced RCA outputs (mirrored), mix knob for balancing live input with computer playback, ESS-driven headphone output with independent volume control, MIDI in/out, driver "loopback" channels for live-streaming and podcasting, and USB bus power with power switch (USB cable included).

Best-in-Class Audio Quality
Equipped with the same ESS Sabre32 Ultra DAC Technology found in audio interfaces costing thousands, the M4 delivers an astonishing 120 dB Dynamic Range on its line outputs. ESS converters also drive the headphone output, which rivals dedicated headphone amplifiers costing hundreds. Ultra-clean preamp circuits produce a measured -129 dBu EIN on the mic inputs. Capture and monitor your audio with pristine clarity.

Best-in-Class 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 (32 sample buffer at 96 kHz).

Best-in-Class 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 160x120 pixel LCD featuring clear, detailed level meters for all inputs and outputs. Enjoy professional-level volume control and feedback to get your sound just right.
