Introducing the M2 and M4

MOTU is now shipping the M2 and M4, two new USB bus-powered audio interfaces for Mac, Windows and iOS offering best-in-class audio quality, best-in-class speed (ultra-low latency) and best-in-class metering with a full-color LCD.

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, MIDI I/O and "loopback" driver channels for live-streaming and podcasting. 

Connect the M2 to your Mac or PC and start laying down tracks with the included Performer Lite or Live Lite production software, plus hundreds of loops, one-shots and sounds from industry leaders Big Fish Audio, Lucidsamples and Loopmasters.

Best-in-class performance

Equipped with the same ESS Sabre32 Ultra™ DAC Technology found in audio interfaces costing thousands, the M2 and M4 deliver an astonishing 120 dB Dynamic Range on their outputs. ESS converters also drive the headphone output, which rivals dedicated headphone amplifiers costing hundreds.

Thanks to MOTU's expertly 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.
