The MOTU M4 4x4 USB-C Audio Interface is a powerful tool for professional audio technicians and engineers looking to capture and monitor audio with exceptional clarity. At its core, the M4 is equipped with ESS Sabre32 Ultra DAC Technology, delivering a remarkable 120 dB Dynamic Range. This technology, typically found in high-end audio interfaces, ensures that the main outputs provide pristine audio quality. The headphone output is equally impressive, driven by ESS converters that rival standalone headphone amplifiers. The ultra-clean preamp circuits are engineered to produce a -129 dBu Equivalent Input Noise (EIN) on the mic inputs, making the M4 ideal for detailed and noise-free recordings.
One of the standout features of the M4 is its speed. Thanks to MOTU's expertly engineered USB drivers, the audio interface offers an ultra-low 2.5 ms Round Trip Latency at 96 kHz with a 32-sample buffer. This ensures that monitoring live inputs such as microphones, guitars, or keyboards through a computer is seamless and responsive, allowing for real-time performance without delay.
Additionally, the M4 includes convenient loopback channels, enabling users to route computer audio back into the computer. This feature is particularly useful for live streaming or podcasting, as it allows users to mix computer output with live inputs directly from the interface within host software. The process is straightforward and enhances the quality of streamed audio content. With the included case and USB cable, the M4 is ready for immediate use, providing a comprehensive audio solution for any professional setup.
