Last updated on June 12, 2024 1:27 am Details


In this review post, we’re going to be discussing the MOTU M4 4×4 USB-C Audio Interface, including an overview of its unique features.

Product Description

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.

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 have never been easier and better-sounding!

Our Verdict

Despite its low price and abundance of features, the Motu M4 delivers on DAC performance, with ratings that compete favorably with some of our finest budget DACs. Its ADC, as previously stated, is a step behind but still far superior to many PC interface cards and consumer interfaces. The headphone amp is the weakest link, but it is still functional.

Overall, even if you only need a DAC, the Motu M4 is a good choice. It provides you with additional input functionality, such as the ability to create a podcast or a YouTube video. Alternatively, test audio equipment (to its limit of course).

Where to Buy

The best place to buy this product has to be Amazon, due to their competitive pricing and fantastic customer service.
