Product Description
In the year 2001 RME started a revolution in mobile audio recording: the HDSP System, consisting of a CardBus card (or PCI card / PCI Express card) plus an external I/O-box has been the world's first audio system, operating at both desktop and laptop. And the world's first professional multitrack system for notebooks at all.In the year 2005 we are proud to look back and conclude: the HDSP system has become a true 'industry standard'. Thanks to continuing firmware and driver updates it stayed a cutting-edge product, still offers un-beaten performance, and still enjoys great popularity among the users.
The Cardbus Interface
For the Hammerfall DSP I/O-boxes Digiface, Multiface and RPM, RME have developed a world-exclusive PCMCIA type II card in Zero wait state CardBus Busmaster technology. With up to 130 MB/s transfer rate in both directions the same basic performance is provided on a notebook as a PCI card would offer on a desktop computer. Additionally the card offers highest compatibility by being 100% Plug & Play compatible under Windows and Mac OS, and being able to share interrupts. The card itself will only use one interrupt (IRQ) for all functions (audio/MIDI.)
The connection between CardBus card and I/O-box is established using ordinary FireWire cable (6-pin IEEE 1394a). The data transfer does not use FireWire protocol, but a proprietary bus protocol by RME. The supplied cable has a length of 4 m (12 ft.). The CardBus card does not provide power to the attached I/O-box. Therefore a compact and light-weight hi-tech switch-mode power supply is included.
