Description
The MOTU M4 is a compact 4×4 USB-C audio/MIDI interface delivering exceptional audio quality and professional-grade performance for musicians, podcasters, and producers. With ESS Sabre32 Ultra™ DACs, it offers 120 dB dynamic range, ultra-low noise preamps, and real-time LCD metering. Built-in loopback simplifies streaming and podcasting, while MIDI I/O and DC-coupled outputs ensure seamless integration with external gear. USB bus power and cross-platform compatibility make it a versatile, portable studio solution.

LCD Metering
A bright, full-color LCD screen shows accurate input and output levels at a glance. This visual feedback helps you set gain levels precisely, avoid clipping, and monitor your mix with confidence during both studio and mobile sessions.

Low Latency
With expertly engineered USB drivers, the M4 achieves round-trip latency as low as 2.5 ms. Ideal for monitoring vocals or instruments in real time without lag or echo, making it highly responsive for both tracking and live performance.

High-Quality Sound
The M4 features ESS Sabre32 Ultra™ DACs and low-noise preamps that deliver exceptional clarity and detail, rivaling interfaces that cost much more. With a 120 dB dynamic range and -129 dBu EIN, it ensures clean, distortion-free recordings across vocals, instruments, and line-level sources.

Loopback Support
Built-in loopback channels make it easy to route your computer’s audio back into your recording software. Whether you’re livestreaming, podcasting, or recording remote guests, you can seamlessly blend system audio with your mic or instrument inputs.
