MOTU M6 Review

A brand new audio interface comes from MOTU, the M6 unit that is a USB-C model compatible with Mac and Windows. This unit will provide the best audio quality and speed in terms of latency and has a really nice metering on it with a full-color LCD display to additionally help you with monitoring levels.

Compared to the earlier models, the M2 and M4, the ports for the microphones are placed on the back for the sake to reduce clutter on the front panel of the interface. Also, this will allow the audio interface to remain compact since you will not have four knobs on the front as well.

MOTU M6 Features

In this interface, you will be able to find 6 inputs. Four of them can be used with combined XLR/TRS jacks and two can accept 1/4 inch line units. As said above, MOTU decided to place all the inputs on the back of the unit, which we found to be really nice to avoid clutter and reduce cables on the front.

Another useful thing that is found here is that the audio interface has outputs to place 2 sets of studio monitors and you can easily switch between them with the knob that is found on the front panel.

An ESS Sabre32 Ultra DAC technology was used to drive both of the headphone outputs, which is really great – and also you will be able to find a separate volume knob for each output. This DAC technology can give up to 120dB of dynamic range which will ensure that the headphones will deliver nice audio quality up to studio standards.

The MOTU M6 also supports up to 32-sample buffer with a round trip latency low down to 2.5ms at 24-bit/96kHz which is spectacular. All of the necessary connections can be found on the interface, so you will lack no flexibility in terms of that. Even MIDI ins and outs are there.

You will also have the chance to use the M6 as a standalone, meaning that can be used as a preamp or a mixer without a computer. You just need to use the multi-blade international DC power adapter and you are good to go.

By activating the monitor button, you will be able to track and monitor the 6 inputs and 48v phantom power if necessary to adjust the levels as needed. You will also have the option to connect the main outputs to a line-level receiver similar to PA or a patch-bay.

As stated by their marketing director, the MOTU M6 will give the sonic quality as its younglings, the M2 and M4, and even will provide additional features for a similar price.

Loopback functionality

In case you are a person that works as a streamer or podcaster, the loopback functionality on the interface will come in handy to you. If you use the loopback, you can mix the microphone signal with any other input signals from the computer and get it mixed back into the computer as well.

You will be able to control this with a mix knob that is found on the interface and end up with a balanced signal that will be ready for your podcasts or reaction videos.
