Really great honest review. Thank you, man!

That's the best explanation of dynamic range and the noise floor I've ever seen. Bravo.

You are a modern day hero Chris, an unbiased voice in a world full of influencers that has sold out!

Solid, solid review. Thanks mate

Thanks for the info! Think I'll keep going forward with my Apollo Twin X.

I have the MT-48. A massive feature is the power and quality of the headphone amps. They're phenomenal and I factored that into the high price. In regards to surround sound and Dolby Atmos mixing, Neumann mentioned that it would be coming to the interface. My biggest gripe with the thing is how hot it gets, but apparently it's designed to be a heat sink and the Anubis interfaces have not failed due to that heat. Thanks for the review!

Excelente vídeo!!!❤

Thank you very much for this excellent video! Your review has helped me see this interface in a new light. I would love to see a video on the MOTU UltraLite MK5, and possibly the RME Fireface UCX II! I am looking to pairing either one of these with the Cranborne Audio Camden preamp.

You enlightened me and kept me from making a costly purchase based mostly on the “Neumann pedigree”. thanks! subscribed.

Great video. Would you happen to know if the Motu M6 or new 828 have dedicated line level inputs?

Bravo for the analogy with the LINE input and the lens on photographic camera.

Out standing!! And honest review thank you for sharing and I will follow 👌👏👍🔥🔥🔥🔥🔥

Thanks for this!👍🏻 Question: I have the SSL 2+ and currently run external preamps through the combo inputs; given what you say about not being a direct path to the converters, do you think I would gain anything in upgrading to an interface that does have direct line inputs, like Scarlett 4i4 or Audient id24 (through inserts) or splurging on an RME Babyface? (the Neumann is just too much of a stretch)

Thanks for the great review! It might be worth to dig deeper into the "bypass the preamps" topic. I don't know the exact design of the MT48. But some general notes: XLR/TRS-Combo inputs are built so that the XLR and TRS connections do not necessarily mirror each other - they can be wired independently. So nothing to tell just from the combo socket itself. It's pretty common that mic inputs are designed in stages. The first stage is the most critical for sound and technical performance. The second or third stage then might just be the same IC that is used for the "real" line inputs. So it is valid to bypass the first stage of the mic pre and groove into just before the second stage. Can't tell how it's done exactly in the Merging/Neumann devices. But this is something they might be happy to shed light on for everyone interested.

After trying the VOLT 4 at my friend's and not quite loving it, I'm curious what you think about the RME Babyface Pro FS? Are the inputs 3 and 4 on that dedicated line level? Remember I use some outboard rack pres like Chandlers and NEVEs so I really want true line-level like you suggested. There's also the RME UCX II but the converters on the BBF Pro FS on paper are actually slightly better and I don't need the other features of the UCX II. Thoughts? I appreciate your advice and I subscribed. :)

Great review Cheers 👏🔥🤘

Thanks a lot for your testing. Did you ever had your hands on a UA apollo x8p and can you tell something about the noise at this one?

Well done and thoughtful review. I just bought one to replace an Apollo Twin, mainly because the Twin has only ADAT in, not out, and also because the twin has only one headphone out, which I found to be an annoyance. I just received the unit so haven't had much time with it. One question though - you said in, the things you don't like, that you can't mirror outputs. However, under settings/monitoring, you can set any mix 2, 3, or 4 to "follow mix 1". Isn't that the same thing? Or am I mistaken? Thanks.

When you recorded the drums with the 8 input adat. Did you record totally raw from that ourboard preamp or did you rout through some analog or dsp compression/limiting.

Hi! What are your white nearfield monitors at [24:00]? I can't see the reference. Thank you!

Love the detail in your review! Have you tried the Apogee Symphony Desktop? Would be cool to hear your thoughts

Hi my friend!! very useful video, thanks for the information :) In your opinion, what interface has better preamp and converter AD-DA between Neumann MT 48 and Apogee Symphony Desktop?

You barely mention the quality of the converters, which is one of the standout features of the unit. While I consider myself an aficionado and also own the Apollo Twin X , I must admit that the MT48 surpasses it in terms of sound quality. This distinction becomes evident when simply listening to music through the unit: the sound becomes more immersive and remarkably clear. To me, it feels as though a veil has been lifted from my ears. The synergy between the preamps and the converters places the MT48 in an entirely superior league, in my humble opinion.

Good afternoon! Please tell me if there is a loop back loop function on the card to send sound from any daw to obs, for example, usually on other cards such a function eats the first two inputs, which is not very pleasant. I will be grateful for the answer

What’s your favorite 2-4 channel interface for music in this range? My Apollo just died and I’m deciding whether to use the insurance money to get another Apollo X Twin Quad (or X4) or one of these.

great review thanks , i have the new RME Ufx 3 it would be nice if you can do one day a review about this interface

Hey Chris, thanks a lot for this really well made and instructive video. I'm kinda new to this nerdy part of audio (but I love it haha), so my question might sound dumb but let's say I'm plugging some outboard gear like a stereo compressor to this mt48. As the preamps can't be bypassed, I guess, even though you said they were pretty transparent, they're gonna mess with the sound and add some color, maybe add gain to the sound and contribute to the overall noise floor of my signal chain. My question is : would you consider this a "bad" thing ? In a mastering scenario, where you'd not want anything unwanted to interact with the sound, would this be an issue ? Anyways thanks for taking the time to create all this educational content, it helps a lot ! Have a lovely day.

Thanks, a lot of useful information here. It would be helpful if you could also measure latency in your interface reviews using something like RTL Utility from Oblique Audio as this information is very hard to come by. I know it depends on many factors, but measurements can at least give a sense of how different products compare when used with a similar setup. That said, this was very helpful in any case.

Very little discussion of the actual sound quality which is the star here. I've had mine for a few months and only my prism lyra was as detailed sounding or better. I just sold my RME because side by side I just couldn't deny the depth of sound on this thing especially with the great sounding headphone amps. Things like reverb tails and compression are so much easier to discern on this unit compared to other units you listed I've also tried and sold. Some good points though. I for one also love not being tethered to my computer screen when recording since I can do everything from the unit itself.

Thanks for the video. I'm rocking a RME interface. They still make drivers for 20 year old interfaces for both Mac and PC. Absolutely great value even considering they're not cheap.

Hi, do you know how to setup loopback in MT48 for OBS? I can't get it, even though they say MT48 has loopback function

I think the touchscreen makes it less future-proof. If its sluggish now, imagine what it'll be like in 10 years.

So, what's the story with the preamps when using line-in balanced inputs? Are they able to be bypassed or not? Seems like a simple problem given the sophistication of this unit.

Amazing video ! Can you test the audient id44?

cool review! was it the Metric Halo ULN-8 MKIV you compared it to ? thanks

Have you done a review on the Merging Anubis?

One quick detail to add. The extra preamp gain is useful when you have a mic that requires a phantom powered uplift. With this unit that isn’t needed… which save on connectors and gear and you won’t have that long lift xlr sticking out the back.

hello, yu find a way to bypass préamp ? in MT48 diagram line 3, 4 i don't see preamp. small apollo (solo, twin, x4) no bypass .. is mt48 enaugh for small mastering, sound looks clear open .. cheers

i feel like for the amount it costs, it should be more refined, no? 1) the screen needs to be way way more responsive. 2) the screen should be bigger by 1-2 inches. 3) Move the dial knob to the right to accomodate for larger screen. 4) the screen should have a 30 - 40 degree angle to it so you can still use the device when it's a bit farther away from you. Right now it looks like it's not tilted enough so you have to have the interface closer to you so you can see the screen easier from a more top down view. i've never used the interface before so i wouldn't know but that's what my thoughts are from watching a bunch of videos on it.

You thankfully mentioned monitoring with up to 4 mixes direct from mt48 not through the daw, and it's around 1 ms, we were waiting for the most important latency figure with daw, not internally, that will allow us to use effects and plugins through the daw, MT 48 then is compared with other audio interfaces if we don't want to use internal monitors or fx.

Reading reviews by other pro's and enthusiasts, the one feature they discuss as the most valuable on this unit, is it's absolutely top of high-end conversion. As in, on par with absolutely anything you might think of (Lavry, MetricHalo, etc). You're right that if the pres are always in the chain to the A/D, that's a bit of a burn, though honestly the noise is still next to negligible in practical terms, and 99% of the tracks will get intentionally mangled far more than what was heard in your 200 pass, just in more deliberate and "colorful" ways (effects, etc). But to the conversion point, some folks pay more than this $ for a strictly standalone 2-chnl D/A, for high end monitoring/mastering purposes. Here you get 4-chnl plus two headphones at absolute world-class D/A. So running final mixes to final outboard analog mastering, or just great monitoring while mixing in-box, it's still high value that way. But you're right that bolting on the pre's and effects makes it look a bit like an "identity crisis", because those feature sort of obscure its strongest feature and selling point - stellar conversion. Honestly, if not for converters, why wouldn't anyone spring for an RME unit (who are also the single exception to your otherwise accurate comment on how most mfg's don't support products for more than a few years) RME's 20 yr old PCI cards are still running today, and their drivers are legendary and are the benchmark.Thanks for the honest review.

Can you tell us what is better. Which Audio Interface is the top of the line. That sounds better then all the rest? For those that have a unilimited budget.

I was thinking about this one because i could get a good deal. But like you say is right they all try to look better but in your test about the noise floor you used the output of the mt48 right? But the DA has only 122dB dynamic range, so maybe a higher noise floor then others? I don’t know all numbers of the other interfaces. It has great input numbers but the output numbers are a bit disappointing. Great that headphones can be loud but please think about your ears you all.

The RME Babyface Pro has 1/4” inputs that are switchable from line level to hi-Z and RME workers have claimed that they don’t touch pre-circuitry in forums. Is that possible? I don’t understand the circuitry difference between Line and Hi-Z and if it’s possible to do that without some kind of pre or circuitry that effects the sound quality or degraded it.

honest review, much appreciated. Pass here. May need to wait to gen 2 or 3.

Hi bro! I'm wondering about what you said at [8:39] "It is not possible to by-pass the internal pre-amps regardless of which input you use". I just watched this other video saying: [1:48] "you can by-pass those internal preamps by just using the quarter-inch jack instead of the XLR jack" kzfaq.info/get/bejne/abmIrJdhsMXTY6c.html Is he incorrect? or there do is a way to have the signal with the pre-amps by-passed? Let me know your thoughts. Thank you.

Are you sure you can't bypass the preamps for the line level inputs? That would be a bit of a deal breaker. Where did you get the info?

Transient response & more towards the midies kind of sensitivity of ribbon mics are pretty good.

Hi, Does DSP work on Adat channels?

would be cool to see a review of your dynaudios and why you went with those.

Hello In Anubis same circuit with preamps? Cheers

Hi ,Nueamann mt 48 will be good for live streaming?

Hi' Bro..what do you think about Babyface pro RME? Thanks

In your opinion does it sound better than RME?

I have read all of the comments and subsequent replies, probably the best review and honest review I've seen. I have one of these units on hold at a local music store and will opt to not buy. I have a UA Volt 1 and will keep that since it does the job fine and I understand how to use it. I bought a pair of Neumann NDH-20 days ago and was looking to pair it for pure sound quality with the Merging Technologies 48 by Neumann but after watching this review I'm good without it. Thanks

Hi. I just bought this machine, cuz I have two Neumann mics at my studio and this would definitely help me get better recordings, but I'm really worried about the heat this one generates, it gets extremely hot, I've set the fans to mid, so sometimes the fans kick in, which is a pain when I'm recording something. I wanna know if the heat really is an issue. Please help.

Does anybody know how can I connect it with aes67 to ethernet on macpro 5.1? help

Excellent video. I have always used UAD Apollo (Twin X) and got an Apollo X6 late last year at a good deal. Was considering selling the X6 and getting this. Watching your video makes me want to just keep what I have. I just do voice work for most part

21:56 the noisefloor of the preamps/MT-48 unit is quite low, you gain a better signal-to-noise ratio overall. It is always useful to have more gain.

Can this interface connect via Dante using the Cat-5 connector?

What your think about RME?

I think it depends on the overall song, but I have liked the sound of DPA condensers, km184s, as well as small diaphragm tube condensers for overheads. I did like the Coles that I have heard but so far not my favorite. Maybe for jazz.

I'm pretty happy with my Apogee Duet 3 for very small jobs. You can bypass the preamps

FMR RNP is one of the quietest Preamps I did use and test. To see it on the second to last position questioning your entire test to be honest. Maybe you got a faulty device or bad/defective Power Supply ?

Great video but I would have liked to see some stuff from RME in the comparisons.

goot,,,, honest... logical man

White Sea mentioned it also does POE?

HAHA!! The phonecall to Neumann. Perfect.

Can you pls test the new Audient ID24 pleaseeeeee

I use Anubis interface. This is the interface that gives me the most headaches. The sound quality is very good but the user experience is very unfriendly. The drivers of RME and Apollo are really much better.

Great video :-) Bad choice for camera though - Sony ZV-E1 ... 🤣 It will be great if you can do such extended review of the Anubis. I believe it is a much better audio interface.

we hope to see in the review the internal latency with its DSP effects, the round trip latency with DAW, also the quality of preamp, and if the reverb is a real studio quality or just a regular mixer reverb, last, if you can tell us what ADC and DAC used here.

want to see the noise floor of Roland, Audient, SPL Crimson (discontinued) Motu, RME and ANUBIS.

"It doesn't support full channel counts at higher sample rates, that's something Berhringer does" ...Thats something a lot of companies do...Motu, Apogee.. it's more the protocol

To the point. No-nonsense. No favours. Honesty is such a lonely word, but this is one exception.

You should review the Arturia AudioFuse Studio.

I want to buy this but everyone appears to be too happy, too quickly without even having had the device for long enough. See what happens when you get over the fact that you just spent $2/3 thousand on it, and have had it for more than a year going from project to project. See if the waiting time everytime you turn it on starts pissing you off everytime you want to use it. Then watch the screen start flickering, it heating up and the fan noise buzzing in your ear. Yeah, its gonna record great vocals but you can probably fix that in post depending on the quailty of your current interface. I'm just not sold on it yet, its too new. Every other interface has been around the block. My RME babyface just sits in the same spot like a rock, no turning on or off, no fan noise, no stupid screen (thats sluggish) because its completely unnecessary when you can do everything you need on your computer screen with your mouse.

This is a great video and you drill down on so many of its features, but you can not compare the converters of this unit with Scarlet and the rest on that list for the exception of the Metric Halo, the industry is suffering from proper AD/DA conversion, almost all gear use the same chips with some spec changes, companies like Merging/Neuman are not in that camp, they are more in the camp of Lavry, Burl, Crane Song, Mytek etc, you will hear the difference as you record multiple audio channels and start stacking and mixing, this is a pro product and is for serious recording, yes it has limitations but look at its foot print, with AES 67 you can really expand, we can not compare this to Behringer converters that is just apples and oranges. The way you dive into converters is just awesome, try to get your hands on some Mytek and Burls and run test tones for your viewers and A and B and you will hear the difference. Thank You.

If you're not using KH AES67 Neumann Monitors with the MA1 alignment software and are stuck on analog still then the MT48 isn't using it's full potential. You got to get the KH series Aes67 monitors, do all the headwork configurations which can be enormously frustrating, but it is very worth the ordeal in getting that setup. I hate analog, the older XLR connections it is just not as good as the AES67 Merging Technology setup. You're getting the pure digital signal without any DA conversion noiseless signal. That is cutting edge. The only cons of the MT48 is my lack of ability in understanding all that it can do.

Greetings, I'm trying as an independent hiphop artist to have the most cost effective mobile professional homemade studio. So far I plan on buying in the near future the ({NUEMAN TLM 49 & THE NUEMAN MT 48 AUDIO INTERFACE}) along with a 16 inch 2023 Macbook Pro and The ISOVOX, All In Conjunction. Im trying to keep my budget under $8,500.00 as my professionally homemade mobile studio to make potentially million dollar hit singles. My question is would this be a wise investment lasting for the next 10 years before upgrading for a new mic or a new audio interface?

Rme Fireface or this?

Um, the sound?

I feel like the touch screen and the OS is very slow

Your comments about running an outboard preamp being degraded by running through an onboard preamp in line is nonsense. Interfaces are engineered to handle this. The camera lense analogy sounds reasonable, but in this case it's not true and not serving your viewer.

Thanks a lot for this honest review. With most of the other MT-48 reviewers you get the impression that they are blinded by the Neumann name tag and are not really capable of judging it critically and point out beside its pros as well its cons.

You had my interest until you said you can NOT bypass the internal pres. No danke schoen for me. I would have to sell my 16 class A pre amps with transformers and I just can't do that!

Reviewer definitely needs to read the manual. He claims it can't do things it can do, and sights problems that are adjustable in the settings. Poor review.

I have owned Antelope Audio Synergy core, UAD X8, Apogee Symphony 11, nothing sounds as good as the MT 48, if you want the best sounding converters on the market buy it, IMO nothing sounds as good as the MT 48, and that extra head room he dismisses is absolute rubbish, running my Neve 1073 threw this box is amazing, and my basses running direct love that head room.

Lots of useful info in here, but a correction: Preamp gain does matter. If you choose to keep your preamp gain low, and turn it up in the DAW, you will be turning up the noise of both the preamp stage, and the AD stage (which follows the preamp stage). Increasing the preamp gain is a better solution, as it does not increase the noise, introduced by the AD stage. When recording, you will ideally want the signal to be as loud as possible, without clipping. Edit: I took one of the corrections out. It was a miss understanding on my part. Sorry about that.

I wasn't impressed with the MT. A presonus quantum2626 and a dangerous music Dbox smokes the mt48...and saves about 700 bucks

A very high end audio interface yet can't %100 bypass the mic preamp?? A very big turn off for me, sorry

Dude sounds like 11:57 he’s a hater 😂

don't agree with bad review....

Things required to review a Neumann interface: 1. A nearly two thousand dollar interface 2. A fully equipped studio 3. A one man band dude

This interview is kind of fail for me. I have the MT48 and there are several things that really didn't get highlighted. First of all its routing flexibility did not get touched. This has 4 32 channel DSP mixers in it with reference quality effects built in. It has separate optimized signal paths for Line, instrument and Mic. You can directly reference a mix or loop back the output of one mixer into another. In fact its loopback capabilities are ideal for stand alone content creation apps. The fan is totally controllable in the software. You can use this as a monitor controller with peered I/O by merging. You can also peer it with another MT48 for networked system. I think a little better and more complete research on your end would have been due for this product. You got some basic stuff wrong here... If you are doing noise tests please use industry standard measurements. If you want to do this right I would look at Julian Krause's channel. He is the gold standard on this.

ok I see lot of misinformation on this channel .....this is my last visit here

He lost me, when he adressed me as nerd.

TRASH!! 🗑️ Get the UA Apollo Twin X

Hello there! I recently watched your KZfaq video where you talked about comparing audio interfaces. Right now, I'm feeling a bit uncertain about choosing between the Audient iD4 MKII and the Volt 1 interfaces. Your guidance would mean the world to me in making this decision. I've reached out to you on all three of your Instagram accounts, left comments on your photos, tried giving you a call, and even sent an email. This decision holds a lot of significance for me, as I'm at a crucial point in my life. Every choice matters, and I genuinely appreciate your assistance. Thank you so much!

Hello In Anubis same circuit with preamps? Cheers
