M2 and M4 Review

MOTU released their two new USB powered interfaces that support Windows, iOS, and Mac. M2 is priced at $169 and M4 is $219. Both M2 and M4 come with two and four channels of audio I/O respectively, complete with individual 48V phantom power on mic inputs, mono and stereo hardware monitoring.

You’ll immediately notice there is a colorful LCD on the front side that shows the input and output power. We’re pleased to see that they put just enough analog knob to control the audio input and output. You can even mix the audio on the fly with zero latency. For something like a small USB interfaces, M2 and M4 are really impressive. There are proper MIDI connections that are pretty rare on this kind of device.

M2 and M4 are clearly top of their class when it comes to audio quality. M2 and M4 utilize ESS Sabre32 Ultra DAC technology, and able to produce top notch clarity with 120dB of dynamic range. Both M2 and M4 come with MOTU’s mic preamps, low noise-DC with analog outputs, and a headphone output with ESS.

The test result of the latency is impressive, total of 2.5ms at 32-bit/96kHz for a round-trip. Like we already mentioned before, M2 and M4 are specifically designed for streamers and podcasters who like a simple, easy to use yet powerful device to produce their content. There is a loopback function that enables user to blend their mic and other input devices with their computer’s output and then send the mixed signal back to their computer so that it can be recorded. Even better than M4 has a better feature that includes a Mix know to balance the live input with the computer’s playback.

No doubt, both M2 and M4 are great products. Whether you’re recording, listening or mixing you can always expect top notch audio quality from these interfaces. And the best thing is that M2 and M4 are really cheap for what they are. Easy to use, full of essential features, and without the features that you don’t need. Convenient audio interfaces and more than 6GB of free loops and samples are a nice bonus to get.

The key differences between M2 and M4 are:

  • M4 has 2x balanced ¼ inch line inputs while M2 has none.
  • M2 has 2x RCA analog out while M4 has 4x.
