“I recently got the M2 (it's supposed to be the 2021 or 2019 revision) and have a lot of problems with it with constant cracking and popping and losing audio, lagging etc.”
“I also went through different source gear, a Burson PM2, an iDSD Diablo and a MOTU M2. I honestly can't tell the difference at all between the three when listening at my prefered volume level.”
“i had the motu m2, and while it was fine for the most part, the bass would distort if i increased the volume,for low to medium volume it was perfectly fine”
“After more testing i find myself tracking around 128, 64 still has occasional pops..”
“I've been using this interface since 2020. Having pre amps with graph visualizers was the most important thing for me and my microphones, so I definitely recommend it.”
“Something similar has started happening to mine in the last couple of days also. I usually have mine set to 96 khz, but now after every reboot I get audio dropouts like the cpu can't keep up.”
“Ive been on a Motu M2 for about a year now and theres plenty of headroom (even with no pad) with the knob zero'd out on the itnerface with my fluence equipped guitars”
“Owned an M2, was torn between the SSL2+ like you… Sold the M2 after realizing my Focusrite Scarlett 8i6 was the best of the bunch…”
“I can get good tones out of neural plugins with the motu m2, but I need to have the knob on the interface at zero or just above it which seems like standard practice unless I'm mistaken. The only annoyance I have is that I can't have the volume pot on my guitar cranked all the way up, so repeatability between takes when recording can be a little bit off.”
“I do enjoy having dedicated RCA and TRS outs so I don’t have to use adapters for the Magni or unplug when I want to use my monitor speakers which is the main reason I got the Motu… and the gain meters hehe.”
“mine started crashing when I only dared to look at a different usb cable that wasn't Motus proprietary one”
“Horrible latency, been using it since 2021 find something else. Terms of sound quality it’s good 7/10”
“I was happy with the little I tried. I use it daily for playback and it works great as long as I use a recent kernel (currently I'm running 5.18.16). Very rarely audio gets locked and I have to turn it off/on.”
“So far, haven’t noticed any issues. Sound quality is great, no latency to speak of, all ins and outs are dead quiet, even crank all the way up.”
“Same issue here, with the MOTU M2 on Windows 11, audio pops and crackles.”
“I'm facing the same issue and I can't single out the cause either.”
“I've had an m2 for a few years, light use.. but it's never given me issues outside of playing cyberpunk (had to change sample rate to correct)”
“In my experience the m2/4 has been one of the best interfaces for guitar, exactly because of the reason the gain can go low enough.”
“i'd pick the SSL2 (i have a motu m2)”
“I can say this one is pretty nice. Has good drivers for headphones and I don't need to use a cloudlifter with my SM7B.”
“I've been having this same problem.”
“The MOTU is rock solid and extremely accurate. My favorite interface out of the five or so I’ve owned over my life.”
“Both are stable workhorses but I have to say M2 for the build quality. The metal knobs are always enjoyable to use.”
“I just bought the M2. No issues driving the 6xxs, it also outputs to both RCA out and headphone out simultaneously.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“This doesn't power speakers. It sends a signal to monitors with their own power source. If your Edifiers plug into the wall for power, this will send a clean audio signal to them.”
“I can check on Windows in a second but I own two M4’s and a M2. When I run them the M4 and M2 with MOTU’s drivers in aggregate on macOS at 48KHz/128 samples I’m getting 3.1/3.3ms of latency”
“Theoretically M4 is a bit better. There were some people reporting problems with some M2s distorting the inputs when headphone amp was cranked to the max.”
“If the audio interface is powered via USB, try disabling the power-saving feature for USB ports. https://preview.redd.it/akb60skp6xhh1.png?width=395&format=png&auto=webp&s=a84a2d84cf4b7d176d21ad91c440d283f10e7e10”
“I can hear more detail and soundstage breadth on my planars but that’s sort of a given since they’re harder to drive and getting a lot more power. Very little difference on IEMs other than having to keep the power wheel turned down.”
“Are your drivers and firmware also up to date for your computer, specifically the motherboard? I had weird issues with audio cutting out briefly and flashing the motherboard to the latest BIOS fixed it. Some kinda USB controller issue I guess.”
“If you are using it in OBS, you have to select force mono in advanced audio setting for your mic. Works perfectly!”
“On the Motu M2 if you press and hold either of the monitor buttons it will switch to stereo monitoring ch1L-ch2R”
“Make sure everything in your windows settings, and in the app you are using, are configured correctly. Plugging in an XLR microphone should only be 1 channel, but it will be in mono, not stereo. Make sure you don’t have a setting on that you shouldn’t and vice versa.”
“No. It's headphone only but you can plug a mic into one of the channels on the interface.”
“Ah sorry, forgot to update that I found the issue. Turned out to be a faulty 3.5 to 6.35mm adapter. Realized It when I went to pull it out the motu m2 and it started sounding clear when I put pressure on it. Switching to a spare I had on hand fixed the issue. Thanks anyways.”
“I feel like a lot of people are giving you shit for this, but not a lot of advice. You bought an audio interface that lives more in the production realm. It’s not going to be plug and play. If you want plug and play go with elgato. You need to run the MOTU into some sort of DAW. I believe the MOTU comes with Ableton.”
