Neumann MT 48 U

Neumann MT 48 is an audio interface equipped with two ultra-low noise microphone/line preamplifiers with up to 78 dB gain, two line/instrument inputs, four monitor/line outputs, and two headphone outputs, each with AD/DA converters. Connectivity can be expanded via ADAT/S/PDIF and AES67. The device also includes a MIDI interface. Integrated processing features a 4-band parametric equaliser and a dynamics processor with 3 modes (gate/compressor/limiter) per channel, as well as high-quality reverb.
