The Neumann MT 48 Audio Interface is the reference audio interface that ensures best possible quality throughout the entire signal chain, from input to output.

Built in partnership with Merging Technologies and aimed at serious musicians, engineers, and producers, the Neumann MT 48 is a desktop 12x12 reference USB-C audio/MIDI interface that ensures pristine sound quality throughout your entire signal chain—from input to output—so you get the very best out of your Neumann microphones, monitors, and headphones, or any other mic.

With four times the resolution of similar interfaces, the MT 48’s high-precision AD converters deliver a staggering dynamic range of 136 dB-A, providing exceptional clarity and detail when recording with professional microphones. Two premium-quality mic/line preamps and two line/instrument inputs offer a remarkable 78 dB of gain, ideal for clean, ultralow-noise recording with condenser, tube, and dynamic microphones, or even low-output ribbons.

For ease of use and simpler workflow, the MT 48 features a high-resolution, color touchscreen with an intuitive user interface. No more switching between hardware and software—all settings are made on the device itself. The built-in digital mixing console offers four separate monitor mixes with integrated talkback. Onboard DSP includes a fully parametric 4-band EQ and a 3-way dynamics processor (gate/compressor/limiter) per channel as well as a high-quality reverb for inspiring monitor mixes. As a unique feature, the MT 48 offers Pre-FX and Post-FX recording, both at the same time. To accommodate larger setups, the interface can be expanded via ADAT / S/PDIF and AES67/RAVENNA, and also works as a bridge from USB to AES67. A MIDI interface is also integrated.

The MT 48 Monitor Mission! - This is a Paid Software Upgrade. Contact us for details!
The Monitor Mission transforms the MT 48 into a freely configurable monitoring controller & multichannel audio interface. In addition to mono and stereo, the Monitor Mission can also handle surround formats such as 5.1 as well as highly sought-after immersive audio formats such as Dolby Atmos 7.1.4. This opens up a whole new field of applications, particularly in the mixing and mastering sector.

What We Think


The Neumann MT 48 Audio Interface is impressive to say the least. Built on platform of the Merging Technologies Anubis, the MT 48 has many of the same feature, but with the wonderful addition of a USB-C connector. Why is this such an important addition/feature? Being that the MT 48 can live on the Ravenna Network with other Merging Technologies, you can utilize the MT 48 as an additional pair of inputs (for any sound source or auxilary input needed, as well as for returns from a summing mixer). However, with the USB-C conenction, this converts the MT 48 into a high end mobile device. If you have to record on location, or you are simply travelling and need to finish up a mix for a client, you can throw the MT 48 in your laptop bag and not sacrifice any quality in overdubs, editing, or mixing – while away from the studio. Further, this provides an affordable way for home studio artists that just really only need a set of stereo ins and outs, but need top shelf conversion and mic pres.
