Record vocals, instruments, or other sources quickly and easily. It includes MOTU Performer Lite and Ableton Live Lite production software, over 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, balanced 1/4-inch line outputs, one-touch hardware monitoring for all inputs, stereo monitoring, four DC-coupled outputs, unbalanced RCA outputs (mirrored), a mix knob for balancing live input and computer playback, an ESS-driven headphone output with independent volume control, MIDI in/out, driver "loopback" channels for live-streaming and podcasting, and USB bus power (USB cable included). Equipped with the same ESS Sabre32 Ultra DAC Technology found in interfaces costing thousands, the M4 delivers an astonishing 120 dB Dynamic Range on its outputs. The 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. 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). When recording and mixing, nothing is more critical than achieving optimum levels. The M4 offers class-leading, full-color metering. The M4 Audio Interface by Motu is a genuine jack of all trades and features outstanding conversion and preamps. The converters inside the M4 are the same as those found in many, much more expensive interfaces. Well-developed USB drivers from Motu allow for a Round Trip Latency of 2.5 milliseconds so even the most critical sound engineer won't have reason to complain. What makes both the M2 and M4 interfaces unique is a multi-colour LCD display, which keeps you up-to-date with important information such as level metering and input clipping. A loopback function has been added, ideal for podcasters that combine computer audio with live-streaming platforms and, to finish, a sizeable software bundle comprised of Motu Performer, Ableton Live Lite and a number of loops and virtual instruments comes included with the Motu M4.
The MOTU M4 is a versatile USB-C audio interface perfect for musicians, podcasters, and content creators seeking professional-quality sound. It offers exceptional audio quality with its ESS Sabre32 Ultra DAC technology, ultra-low latency, and a full-color LCD for clear metering. However, its advanced features may be overwhelming for beginners unfamiliar with audio interfaces.

Troubleshooting
No sound coming from the outputs.
Check the volume levels on the M4, your computer, and your studio monitors or headphones. Ensure the correct output is selected in your DAW or system preferences. Verify that the input signals are properly connected and sending audio.
High latency or audio delay.
Adjust the buffer size in your DAW settings. Lowering the buffer size will reduce latency but may increase CPU usage. Ensure you have the latest drivers installed from the MOTU website.
Microphone or instrument input not working.
Check the input gain on the M4. Ensure phantom power is enabled for condenser microphones. Verify that the correct input is selected in your DAW.
Loopback not functioning correctly.
Ensure that the loopback feature is enabled in the MOTU M4's driver settings. Check that your DAW is configured to receive the loopback signal.
