NEUMANN / MT48 オーディオインターフェース

MT48 is an audio interface developed in close collaboration with Swiss manufacturer Merging Technologies. Its vast dynamic range, excellent converters, preamplifier, and headphone amplifier are all designed to the highest standards.

■Audio Interface
■USB-C

■Key Features
Best-in-class AD converter resolution with 136 dB dynamic range
2 high-quality mic/line preamps and 2 high-quality line/instrument inputs
Four line/monitor outputs
2 ultra-low impedance headphone outputs with adjustable crossfeed
ADAT/S/PDIF optical in/out, AES67, MIDI/GPIO
Two driver outputs per input channel for pre-FX and post-FX recording
Intuitive touchscreen user interface
Can also operate stand-alone as a kissing console

High-precision AD converters operate with an astounding 136 dB dynamic range. This gives the MT 48 four times the resolution of comparable audio interfaces.
MT48 features two ultra-low noise mic/line preamps with up to 78 dB gain, two line/instrument inputs, four monitor/line outputs, and two excellent headphone outputs, all with state-of-the-art AD/DA converters.
Expansion is possible via ADAT/S/PDIF and AES67, and a MIDI interface is integrated. 4 independent monitor mixes can be controlled directly on the unit via the touchscreen. Onboard processing includes a 4-band full parametric EQ, per-channel 3-way dynamics processor (gate/compressor/limiter), and high-quality reverb.

MT48 combines an audio interface and digital mixing desk in one product, allowing DSP processing to be used for monitoring only, for effects while recording, or both simultaneously. The unique Dual Output Technology allows wet and dry signals to be recorded simultaneously via separate driver channels. Thus, you can also revert to an unprocessed backup if necessary.
