4-in / 4-out USB audio interface with studio-quality sound

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.

- ESS Sabre32 Ultra DAC technology for superb analog sound
- The same converter technology used in audio interfaces costing thousands
- Measured 120 dB dynamic range on outputs
- Measured -129 dBu EIN on mic inputs

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 is the only audio interface in its class with a full color LCD featuring clear, detailed level meters for all inputs and outputs. Enjoy professional-level volume control and feedback to get your sound just right.

The M4 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 live mics and/or guitar inputs from the M4 in your host software for live streaming or podcasting. Streaming and podcasting has never been easier and better-sounding!

    So good
    I would have paid quite a bit more for this thing, it's that good. Also, it shipped super fast and customer service was amazing.

    Amazing quality for the price

    Quite impressive
    I just got the m4 earlier this week, as I needed a portable interface with an extra set of line in/out. I had used MOTU products back in university so I have at least some familiarity with the brand, and the price/feature set is just right. The unit is built very well, and has a very nice display with quick and accurate meters which is nice. Read more

    Low latency + great guitar DI
    Currently using the m4 to drive my headphones, a dynamic mic and play guitar. The guitar DI signal is great and the Motu doesn't need a DI box in front of it to sound good. Using Motu's drivers, I'm able to run top-end amp sim plug-ins with <4ms RTL. Read more

    Highly recommended!
    The MOTU M4 is just incredible for its price.
    I upgraded my interface for less than the price of the previous one!

    Conversion specs regarding DA are among the best on the market.
    A to D follows with a great gain & dynamic range and low noise floor level. Read more
