The HDSP System was a revolution when released by RME in 2001, consisting of a PCI or CardBus card plus an external I/O-box has been the world's first audio system, operating at both desktop and laptop. And it was the world's first professional multitrack system for notebooks at all. Now in conclusion the HDSP system has become a true 'industry standard'. Thanks to continual firmware and driver updates it stayed a cutting-edge product, still offers un-beaten performance, and still enjoys great popularity among the users.
The PCI Express card uses RME's own audio bus, already known from the PCI version, operating in combination with Multiface II, Multiface, Digiface and the RPM DJ interface. RME interfaces can easily expand their systems so that it operates with the latest and fastest PCI Express computers and Windows Vista, so that you are not loosing all the money formerly invested in audio hardware. A great additional option the HDSPe PCI card has is that it can be used directly with RME's Time Code Option Module, offering an SMPTE controlled operation.
RME HDSPe PCI Express FireWire Audio Interface Features:
- Supports 2.5 GBps line speed
- Card provides a transfer rate up to 500 MB per second, 250 each direction
- PCI Express Card and I/O box uses ordinary FireWire Cable
- Data transfer uses RME based proprietary bus protocol
- PCIe card operates as power supply for attached I/O box through the FireWire cable
RME's HDSPe PCI Card is not based on a PCI to PCI Express bridge, which would simply add PCIe to existing PCI technology. It is a newly developed genuine PCI Express solution, which has a great new format, achieving significant performance gains in multitrack audio. RME's flash update technology ensures future firmware improvements, adjustments, and bugfixes to be installed easily at any time.
The PCI Express interface of the HDSPe system is based on the PCI Express Base Specification v 1.1. It represents a 1-Lane PCI Express Endpoint Device and supports 2.5 Gbps line speed. Thanks to the packet-based full duplex communication, the card provides a transfer rate of up to 500 MB/s - 250 MB/s in each direction.The connection between PCI Express card and I/O box is established using ordinary FireWire cable (IEEE 1394, 6-pin). The data transfer does not use FireWire protocol, but RME's own proprietary bus protocol. The supplied cable is 12 feet long. The PCIe card operates as power supply for the attached I/O-box (Digiface, Multiface, Multiface II, RPM) over the FireWire cable.
