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. For highest usability and connectivity the XT can also be used with USB 2.0 (computer I/O limited to 70 channels). 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.
