Neumann MT 48 US - Premium USB-C Audio Interface with Touchscreen Control, AES67, MIDI Interface, & ADAT/S/PDIF Expansion Connectivity

I've had this only for about a week know, and I love everything about it. It's easy to use, sounds amazing, great build quality, and most important for me it works flawlessly on Windows 11 (unlike the Apollo, which has laughably mediocre Windows support). I guess the only downside to coming from an Apollo to this is no longer being able to use UAD plugins right out the box during calls (which you couldn’t even do on Windows in the first place lol) but that was a very simple fix with LightHost and a virtual audio cable. Well worth the upgrade.

I dont usually do reviews but I received a used item so im returning it, be aware if the box is not sealed in plastic you got yourself a used item.Only doing 5 star so yall can see it 🤫

I’ve owned and tested a range of high-end DACs and streamers—Topping, RME, and the Eversolo (which has some of the best visuals in the consumer space). The Neumann MT 48 sits in a different league—both in terms of capability and complexity.My use case is somewhat unconventional: I run the MT 48 into a multichannel AVR for playback and calibration. While that’s not its target audience, it offers a unique benefit—native support for high-performance XLR measurement microphones. That allowed me to upgrade my Dirac Live calibration workflow in a way few interfaces could match. Still, its ideal use case probably isn’t system calibration—it just happens to handle that especially well.I picked up the MT 48 based on its reputation for performance, its surprisingly consumer-friendly I/O layout, and its sleek touchscreen interface. And in those areas, it absolutely delivers. The audio quality is transparent and refined, the touchscreen is responsive, and the routing flexibility is powerful.That said, even with deep experience using other interfaces, I ran into configuration issues—especially around monitor bus routing and firmware updates. Things that should be simple, like toggling between output mixes or tracing a silent signal, took longer than they should have. The interface doesn’t always offer feedback when routing isn’t working as expected, and that can throw off even experienced users.Fortunately, Neumann’s customer service was responsive and helpful. I reached out about the firmware issue and routing confusion, and they got back to me quickly with clear guidance. That support made a big difference.If you’re coming from RME or other pro audio ecosystems, this interface is probably right up your alley. But if you’re used to plug-and-play devices, be ready to spend some time learning the MT 48’s architecture. Once configured properly, it integrates beautifully—and can becomes an incredibly capable part of your system.

The original box was not sealed. There were fingerprints on the screen of the device. It is possible that the device was returned to me by someone and sold to me as new. This is unacceptable when selling equipment of this class. If the packaging has been opened, this should be indicated at the time of sale.

Really well built but I’ve had some issues with Mac OS Sonoma. Still, phenomenal sound

This Unit simply put is spectacular.......if you want that experience where you feel like you have taken a carpet off your monitors.....this will do it.....and yes even compared to Universal Audio interfaces.....There is no Higher Player in Digital Audio than Merging Technologies....this is their rebadged Neumann step child....with all the things you need for your home Studio....FACT...to quote a very famous producer who just heard a remix of my new single........"That Sounds Like a Record Now " !.....and its future proof !!!...

Well design awesome software inside something small any videos I’ve seen on this product are really close to specs my only issue is the turning knob is not well made sometimes it’s sticky or wobbly

Phenomenal preamps. Amazing headphone amps.
