The Neumann MT 48 U is a high-resolution USB audio interface that brings Neumann’s reference-grade studio quality to recording, mixing, and monitoring.
Co-developed with Merging Technologies, it provides ultra-low-noise preamps, dual-converter architecture, and DSP-based mixing & processing.
The “U” version connects via both USB-A and USB-C, offering broad compatibility with computers and mobile devices, and includes a protective softcase and both data cables.
