Current laptops offer calculation power on par with fast desktop systems. Dual core processors, 2 Gigabyte RAM, big and fast hard drives, dual monitor operation with a quick graphics card - today all this is also available small, lightweight and portable. No wonder that RME receives more and more requests for a portable MADI solution. Thanks to the fast PCI Express bus and the latest, extremely powerful FPGAs, RME is proud to present another milestone in the company's history - the world's first and only MADI interface for laptops, based on an Express Card: the MADIface! Consisting of the HDSPe Express Card MADI and a small breakout box, the MADIface offers full MADI power: 64 channels input and 64 channels output, up to 192 kHz sample rate, in MADI embedded MIDI transmission, complete TotalMix that is even remote controllable and has all features of the 'bigger' HDSPe MADI, as well as lowest latency and CPU-load. To make the usage as comfortable as possible, the power for the breakout box is provided directly by the ExpressCard, so no external power supply is required.
