394-Channel 192 kHz, USB 3.0 Audio Interface
RME's MADIface XT is the world's first USB3 audio interface - and the world's smallest portable interface that provides access to hundreds of audio channels in such a small package.
Its unique PCI Express port connects to External PCI Express cards as well as adapters to Thunderbolt, providing all the fastest interfacing technologies available for maximum channel count and lowest latency in one unit.
The MADIface XT includes a powerful digital real-time mixer, the Hammerfall DSP mixer, based on RME’s unique, sample-rate independent TotalMix technology. It allows for practically unlimited mixing and routing operations, with all inputs and playback channels simultaneously, to any hardware outputs.
