MOTU M4 4‑Channel USB Audio Interface - High-Performance USB-C 4-In/4-Out Audio Interface

MOTU M4 4-Channel USB Audio Interface

The MOTU M4 4-Channel USB Audio Interface is designed to deliver top-notch audio quality and performance for musicians, producers, and podcasters alike. Equipped with the cutting-edge ESS Sabre32 Ultra DAC Technology, it provides an impressive 120 dB dynamic range on its main outputs. This technology also powers the headphone output, ensuring that you get the highest quality sound, comparable to dedicated headphone amplifiers that come with a hefty price tag. Whether you're capturing audio or monitoring your projects, the M4 ensures pristine clarity with its ultra-clean preamp circuits, producing a measured -129 dBu EIN on the mic inputs.

With the MOTU M4, you can enjoy the benefits of class-leading speed, significantly reducing latency and providing real-time monitoring of live inputs. This means you'll only experience an ultra-low 2.5 ms Round Trip Latency when processing through your host software at 96 kHz with a 32 sample buffer. This audio interface stands out with its full-color LCD screen that gives detailed level meters for all inputs and outputs, making it easier to manage your levels accurately. Professional volume control and immediate feedback ensure your mixes are always spot on.

The M4 is also a content creator’s best friend. Its driver comes with loopback channels enabling you to route computer output back into your host software, facilitating seamless live streaming and podcasting. These features, combined with its rugged metal construction and portability, make the MOTU M4 a versatile tool for any audio professional looking for superior performance and reliable results.
