Motu M2 & M4 are two new affordable DC powered audio interfaces with LED live metering and unique loopback function perfect for music  & content creators.

MOTU has today released M2 & M4, two new USB bus-powered audio interface for Mac, Windows, and iOS. It offers best-in-class audio quality, best-in-class speed (ultra-low latency) and best-in-class metering with a full-color LED. With two and four channels of audio I/O, respectively, the M2 and M4 include individual 48V phantom power on both mic inputs, mono, and stereo hardware (direct) monitoring and full MIDI I/O.

One highlight is the LCD display with which you can meter audio very well. Another great feature is the new loopback function that allows you to record computer audio, perfect for YouTubers, streamers… The M2 and M4 are DC coupled and is, in my opinion, an important feature in times where we have Ableton CV Tools.  Great new affordable audio interface from MOTU.

The M2 and M4 deliver unmatched audio performance at an entry-level price point,” said Jim Cooper, Director of Marketing at MOTU. “With simple plug-and-play operation and a complete package of bundled software, instruments and sounds, users can get started making music right away.”

Best-in-class performance

Equipped with the same ESS Sabre32 Ultra DAC Technology found in audio interfaces costing thousands, the M2 and M4 deliver 120 dB Dynamic Range on their outputs. ESS converters also drive the headphone output, which rivals dedicated headphone amplifiers. Thanks to MOTU’s engineered USB drivers, the M2 and M4 deliver class-leading, ultra-low 2.5 ms Round Trip Latency (with a 32 sample buffer at 96 kHz). The M2 and M4 are the only audio interfaces in their class with a full-color, high-resolution LCD featuring clear, detailed level meters for all inputs and outputs.
