USB-C audio interface for DJ groove production

The Motu M4 is a USB-C audio interface built for DJ groove production and live streaming. It offers four inputs and four outputs with ESS Sabre32 Ultra DAC technology on the main outputs and headphone output. Ultra-clean preamp circuits provide a measured -129 dBu EIN on microphone inputs for pristine capture.

Latency metering and loopback for live monitoring

MOTU's engineered USB drivers deliver class-leading ultra-low 2.5 ms Round Trip Latency at 96 kHz with a 32 sample buffer. A full colour LCD displays detailed level meters for all inputs and outputs, the only interface in its class to do so. Convenient loopback channels route computer output back to the host for mixing with live microphones or guitar inputs during streaming or podcasting.

Professional dynamic range and headphone power

Main outputs achieve an astonishing 120 dB Dynamic Range using converters found in interfaces costing thousands. ESS converters also drive the headphone output to rival dedicated headphone amplifiers costing hundreds. The USB-C connection supplies power and data for desktop or mobile recording setups without an external power supply.

Questions about this item

How do I install the MOTU M4 and what step is often missed?

Connect the M4 via USB-C, install the MOTU driver package from the manufacturer, then set the buffer to 32 samples at 96 kHz in your DAW to achieve the quoted 2.5 ms round-trip latency; many users forget the driver and run only the generic class-compliant mode.

What maintenance or replacement will the M4 need over time?

The M4 has no user-serviceable parts; keep the USB-C port and combo XLR/TRS jacks free of dust, verify driver compatibility after major OS updates, and replace the USB cable if it becomes intermittent.

What limit appears first during long sessions with the M4?

Sustained use is typically limited by the host computer's USB bus power and thermal throttling, not the interface itself, which maintains 120 dB dynamic range on the main outputs and -129 dBu EIN on the mic preamps continuously.
