he MOTU M4, a USB-C device designed for recording, mixing, podcasting, and more. Offering loopback connections that allow podcasters to record skype calls with absoutely no fuss, the M4 can feed audio to both computers and iOS devices, thanks to its USB-C connection.

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 main 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.

With two XLR-1/4" inputs, the M4 can handle microphones, line-level instruments, or Hi-Z instruments such as guitars and basses. Selectable phantom power is on hand for condenser mics, and the preamps are exceedingly clean with an EIN of -129 dB; this ensures you only hear the instrument or voice being captured, rather than any noise from the preamp. Whether you need a clear-sounding vocal for a podcast or a transparently recorded guitar for a mix, the M4 will deliver the goods.

The M4 has digital loopback channels, so you can route audio from your computer directly into your recording software. What does this mean? If you're recording podcasts, you can record guests from Skype or any other VoIP software without incurring horrible feedback or other audio issues; it all works seamlessly.

Do you like to mix with harware compressors, equalizers, or other pieces of outboard gear? If so, the M4 has you covered with line outputs over RCA or 1/4" connections and balanced 1/4" line inputs on the rear panel. With the M4, you can run audio through your favorite hardware pieces, and record it straight to the interface, making the unit adept at handling hybrid mixing setups. 

The M4 is equally suitable for producers, thanks to its MIDI I/O. You can use your favorite MIDI controller with the M4 and free up a USB port on your computer in the process. Or, you can run MIDI from the M4 to your favorite hardware synth, capturing the glorious tones of your favorite compatible hardware synth through the M4's analog pres.

In this way, the M4 is all about providing the budding content creator options, no matter the discipline. The M4 puts everything from podcasting to music production within your grasp.

Mirrored Monitoring

The M4 has balanced 1/4" outputs for professional-level monitoring, and also features mirrored RCA outputs for feeding receivers and other unbalanced gear. With a 1/4" headphone output, you can monitor your work privately.

Loopback Channels for Podcast Recording and Live Streaming

The M4's included driver provides convenient loopback channels to your host computer, so you can easily capture your computer's output. Combine computer audio with live mics while recording in your DAW, allowing you to capture guests over Skype or other VoIP programs. You can also use the loopback function while streaming live to sites like Twitch.

Professional-Level Audio Quality

Equipped with the same ESS Sabre32 Ultra DAC technology found in audio interfaces the pros use, the M4 delivers 120 dB of dynamic range on its main outputs. ESS converters also drive the headphone output. Ultraclean preamp circuits produce a measured -129 dBu EIN on the mic inputs; this means while recording, you'll only hear the mic, not the mic pre.

Software Included

The M4 includes Ableton Live Lite and MOTU Performer Lite, which are DAWs geared for music recording and production. Also included are over 100 instruments for Performer Lite, as well as 6 GB of loops, sounds, and one-shot samples for either DAW.

Standalone Operation

The M4 can be used as a standalone preamp and basic mixer, with no host computer required. Simply engage the monitor button for each input (and 48V phantom power, if needed) and adjust the preamp gain as needed. Connect the main outs to any line-level destination, such as a PA or patch bay. The unit is bus-powered over USB, but with a USB Type-C power adapter.
