The MT 48 is an audio interface without compromise. With its huge dynamic range, superior converters, preamps and headphone amplifiers, it sets new standards in sound quality. Internal DSP power allows for monitor mixes with sophisticated EQ and dynamics processing - all intuitively controlled via touchscreen.

• Class-leading AD/DA converters with enormous dynamic range
• 2 premium-quality mic/line preamps, 2 pristine line/instrument inputs
• 4 line/monitor outputs, 2 high-performance headphone outputs
• USB, ADAT and AES67 connectivity, integrated MIDI interface
• Intuitive touchscreen user interface
• DSP processing (EQ, dynamics, reverb), 4 independent mixers
• Two driver outputs per input channel for pre-FX and/or post-FX recording

About Neumann
Neumann.Berlin has been on the cutting edge of studio technology for close to a century and has been part of the Sennheiser Group since 1991. Founded in 1928, Neumann has created such microphone legends as the U 47, U 67, and U 87. Since 2010, Neumann.Berlin has established a line of award-winning studio loudspeakers, followed by very successful studio headphones starting in 2019. Neumann’s first audio interface MT 48 thus becomes the centerpiece, connecting the entire portfolio to create the perfect studio.

The Perfect Link

MT 48

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.
