Overview

The MOTU M6 is a 6-input, 4-output USB-C audio interface that brings flagship-level audio conversion to a mid-range form factor. At its core are ESS Sabre32 Ultra DACs — the same converter technology found in interfaces costing several times more — delivering a measured 120 dB dynamic range on the line outputs and an exceptionally low -129 dBu equivalent input noise on the microphone preamps. This level of performance means recordings capture fine detail with minimal coloration, and monitoring playback reveals nuances that lesser converters simply miss. The USB-C connection, paired with MOTU's expertly optimized drivers, achieves a class-leading 2.5 ms round trip latency at 96 kHz with a 32-sample buffer, making it practical to monitor live inputs through software plug-ins without perceptible delay.

Beyond raw audio specs, the M6 includes thoughtful workflow features that set it apart. The full-color LCD screen displays real-time level meters for every input and output — a rarity in this price range that eliminates guesswork when setting gain. The A/B monitor switch allows instant toggling between two connected speaker pairs for reliable mix referencing. Two headphone outputs offer independent volume control, and the second output can be switched to monitor Line Outs 3-4 for a completely separate cue mix. Loopback channels simplify live streaming and podcasting by routing computer audio back into the host software alongside live microphone inputs. The M6 also operates in stand-alone mode when powered by its included DC adapter, functioning as a high-quality preamp and monitor controller without any computer connected. Bundled with Performer Lite and Ableton Live Lite 11, the M6 provides a complete recording solution from unboxing.

Key Features

Best-in-class audio quality — Equipped with the same ESS Sabre32 Ultra DAC Technology found in audio interfaces costing thousands, the M6 delivers an astonishing 120 dB Dynamic Range on its line outputs. ESS converters also drive the headphone outputs, rivaling 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 M6 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 M6 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.

Loopback for live streaming and podcasting — The M6 driver provides convenient loopback channels to your host computer, so you can easily route computer output back to the computer, where you can mix it with up to four mics (and/or guitars) from the M6 in your host software for live streaming or podcasting. Streaming and podcasting has never been easier and better-sounding!

Unique A/B Monitor Switch — The M6 is the only audio interface in its class to offer A/B monitor switching. Connect two pairs of monitors and quickly check your mixes on each pair with the push of a button.

Professional grade headphone outputs — Driven by ESS Sabre32 DAC Technology, both headphone outputs monitor the signal on Monitor Outs 1-2 and feature independent volume control. The second headphone output includes a 3-4 switch that allows it to independently monitor Line Outs 3-4, which can have a completely separate mix from the computer.

Music production software, 100+ virtual instruments and 6 GB of loops — Performer Lite provides everything you need to record, edit, mix, process and master your own music tracks quickly and easily. Plug in your mic, guitar and keyboard and start tracking with over 100 instruments, dozens of effects plug-ins, guitar FX processing, 6 GB of loops and sounds, and much more. Live Lite 11 is a lightweight version of Ableton Live 11 with all of Live’s essential workflows, instruments and effects.

Stand-alone operation — With the included multi-blade international DC power adapter connected, you can power the M6 when the computer is turned off (or completely disconnected from the M6). This allows you to monitor any live inputs you may have (mics, guitars, keyboards, etc.) without a host computer or iOS device needed.

Solid and secure construction — Rugged metal construction throughout includes a solid yet lightweight extruded aluminum alloy shell, steel faceplates, precision-knurled knobs, and a universally compatible Kensington security slot.

A tradition of engineering excellence — Decades of award-winning product engineering for hit songs, mega tours, primetime shows and blockbuster movies goes into every MOTU audio interface.
