Neumann - MT 48 Audio Interface

The Perfect Link

The MT 48 brings Neumann quality to the digital workflow. It is the first audio interface in its class that is able to capture the full dynamic range of Neumann microphones and is optimally matched to the KH-Line of studio monitors and Neumann headphones. The result is an ideal signal chain without any bottlenecks: uncompromising sound quality from the microphone diaphragm to your ear.

Swiss Precision Inside

The MT 48 was developed in close cooperation with the Swiss manufacturer Merging Technologies, whose high-precision AD converters offer a staggering dynamic range of 136 dB. This gives the MT 48 four times the resolution of comparable audio interfaces.

The MT 48 comes fully equipped for the reference-class personal studio: two extremely low-noise mic/line preamps with up to 78 dB gain, two line/instrument inputs, four monitor/line outputs and two superb headphone outputs, each with state-of-the-art AD/DA converters. The MT 48’s connectivity may be expanded via ADAT / S/PDIF and AES67; a MIDI interface is also integrated. Four separate monitor mixes can be controlled directly on the unit via touchscreen. On-board processing 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. So musicians get inspiring sound for top performances. And there is still plenty of DSP power for future developments.

Record With or Without Effects. Or Both!

The MT 48 is an audio interface and digital mixing desk in one. You can use its DSP processing for monitoring only, or you can print effects while recording. Or both at the same time! Thanks to the unique Dual Output Technology, wet and dry signals can be recorded simultaneously via separate driver channels. So, if necessary, you can fall back on an unprocessed backup.

A New User Experience

Despite its enormous scope of features, the MT 48 always remains easy to operate. All settings can be made on the device itself via the built-in touchscreen. The perfect monitor mix is just a touch away! Simply use your fingers to adjust pan pots, channel faders and much more, without having to switch to a mixer software on your computer. The MT 48 can even be operated stand-alone as a mixing console.

The MT 48 leaves nothing to be desired: audio quality at the highest level, built-in DSP processing, comprehensive expandability, and convenient operation via touchscreen. The MT 48 is the missing link in the Neumann universe, connecting microphones, loudspeakers and headphones to create the perfect studio.

NEW: Monitor Mission for Mastering and Mixing Immersive Audio 

Thanks to its touchscreen user interface, the MT 48 can be configured for various application scenarios using dedicated "Missions". The Monitor Mission transforms the MT 48 into a comprehensively equipped, highly flexible, state-of-the-art monitor controller. In addition to mono and stereo setups, any surround and immersive formats can be configured. On board are precise trim and delay functions to compensate for level and time-of-arrival differences, as well as EQs with up to 24 bands per output channel for room adjustment. Flexible bass management and downmix are also part of the Monitor Mission.  
 
In use, speaker sets and headphone cues can be conveniently managed, speakers can be muted or monitored solo, and you can switch between mono, stereo and surround or immersive formats. The Monitor Mission is the ideal tool for mixing and mastering with the flexibility required today to ensure perfect sound for every medium and every playback device. 

The Monitor Mission license code is available free of charge until January 1, 2025 in our product registration after successful MT 48 registration.
