USB AUDIO INTERFACE During the fall of 2019 MOTU announced the launch of its new M2 and M4 USB interfaces, for Mac, Windows and iOS that offer the best audio quality imaginable, the best latency (ultra-low) and the best signal measurement in its category incorporating a fantastic full color LCD screen for this purpose. With two and four channels of audio I/O respectively, the M2 and M4 include individual 48V phantom power on both microphone inputs, mono and stereo (direct) hardware monitoring, and MIDI in and out among other features.




Best-in-class performance


Equipped with the same ESS Sabre32 Ultra™ DAC conversion technology found in audio interfaces costing thousands of euros, the M2 and M4 offer an astonishing 120 dB of dynamic range on their outputs. The ESS converters also control the headphone output, allowing them to compete in playback quality with dedicated audiophile headphone amplifiers costing hundreds of euros. Thanks to the USB drivers designed by MOTU's expert programmers, the M2 and M4 offer an ultra-low send and return latency of 2.5 ms total that will be leading in their category (setting the buffer to 32 samples at 96 kHz). The M2 and M4 are the only audio interfaces in their class with a full-color, high-resolution LCD display with clear, detailed level meters for all their inputs and outputs.
