M4 4x4 USB-C Audio Interface

I have used MOTU interfaces for decades. I just keep coming back to them? Why? They sound completely transparent and have rock solid drivers for Windows. The preamps are clean and clear, the noise floor and distortion are extremely low, and jitter is non-existent. It does not hurt that they are priced so competitively. My current home studio setup consists of an MOTU M4 and a pair of Neumann KH120II monitors and Luna Pro, and I am very pleased with it. Features that set it apart at this price point are the LED meters and physical direct monitoring mix control. Nothing else has those, and they work very well. My only complaint is the headphone amp's power. It is on the weak side, but that is the price you pay for USB bus power. Headphone amp output requires power, and there simply is not much available after running the rest of the device. The good news is the headphone out can serve as a preamp of an external headphone amp, so the problem is easily solved. I use a Schiit Heresy to drive my cans. Very happy overall. All the stars.

I discovered the MOTU M series of audio interfaces when I was looking to solve a specific problem that I had. I'm using this as my primary audio input and output for my PC, driving both my monitors and headphones with independent volume control is an incredible quality of life enhancement. The LCD display for the levels is extremely helpful when I'm dialing in my gain on my input or trying to confirm that I'm speaking loud enough. The ability to mix between playback and input monitoring when monitoring your input gives a very dialed and natural experience to even normal calls, gaming, or meetings for work. I take advantage of the ASIO drivers in my DAW for low latency audio as well, and this thing fits right in. It has a dedicated loopback output in the software as well, so you can direct loopback to be captured as a source out of the box if that's something you need for your workflow. It has an impressive array of physical inputs and outputs, to the point where I'm not even able to take full advantage of it yet in my setup. One unexpected bonus for this was that the 48V phantom power switch is on the front of the unit, where on my previous audio interface phantom power was running 24/7. With the MOTU M4, I'm able to turn off the mic's power quite easily, leading to a much more efficient setup. It was easy to set up and remains a hassle-free component of my everyday usage of my computer. It's a little expensive but worth every penny for me.

After a fair bit of searching and testing, this is the best audio interface I've found for a home studio. The amazing parts: Usb-c to usb-a 2.0 bus powered! No dealing with an extra power cable Very low noise floor and great sounding preamps Powerful enough for most headphones but also has plenty of outputs for an additional headphone amp Direct monitoring is handy Built in loopback is rare on interfaces of this price and it's very nice to have Very low latency Could be useful depending on use case: The screen is useful and high quality but I tend to just monitor in Ableton so I haven't used it a whole lot. With that being said, it is still a rather nice feature to have. Usb-c is nice to have but I wouldn't consider it a deal breaker if it had a different USB standard. The included software is nice especially if you're just starting out. Bad: Not exactly a negative but more something to bear in mind. The Motu M2 is basically the exact same interface but with fewer inputs and outputs. If you don't think you need the extra inputs and outputs that the M4 has, the M2 is a much better deal for you. Edit after a couple years of ownership: the Motu M4 is still my absolute favorite interface, however there is one quirk that I have found. I'm not sure whether it's MOTU's fault or Windows, but at least partial blame goes to MOTU considering no other interface I've used has had this bug. Occasionally it would output and record sound as if it had been pitch shifted (think Alvin and the Chipmunks). I believe it is some sort of clock sync error with Windows. After getting into contact with their technical support (who deserve props for not just regurgitating the same useless copy-pasted answers and actually problem solving effectively), I was presented with a simple solution: disable fast startup on your PC. Once I did that, the problem was immediately solved and has not occurred again for well over a year. Personally, I still think it's an excellent interface and I wouldn't hesitate to recommend it despite that bizarre quirk. Latency is still incredibly impressive and the preamps are still very clean. I've also come to love the monitoring screen, it's become very difficult to go back to an interface without it.

Ya me habían recomendado la Motu M4 y sin duda por el precio es una interfaz muy completa, se nota una gran nitidez y profundidad en sus salidas de audio tanto en la de los monitores como en la de los audífonos a comparación de DAC's que rondan un precio similar, no presenta ruido de poping ni claping. Había escuchado que las perillas estaban algo flojas pero veo corrigieron ese problema en éstos nuevos lotes. Aún me falta probar las entradas con micrófonos. Ya veré a futuro su vida útil.

Great construction, solid feeling knobs. Powered by USB so one less cable to worry about. Use it with a MacBook and it just worked out of the box, no messing about with drivers or firmware. Has big midi ins and outs also which I thought I wouldn’t need but came in really handy with a old synth that only has midi. the screen is great and gives you a much greater representation of your sound level compared to a lcd strip. lastly being able to route audio from your laptop back into it is very handy for sampling in a daw. great box.

Does a great job but you may benefit from using a USB-C to USB-C cable (not supplied) PC/Mac interface is great and intuitive. Sound quality as good as you would hope for. Lovely display on the unit helps set levels. Chose this over the "lower" model as it has 4 ins/outs and midi but didnt need the "bigger" versions with more ins/outs.

Easy to use with great interface, installed all extra software with no problems.

Ravi de cette carte son ou je branche mon micro et mes enceintes actives ,fait tres bien le job sans que l'investissement soit élevé ,un tres bon produit
