36-bit Embedded DSP
All Delta cards contain a 36-bit embedded DSP enabling a software-driven patchbay/router for all analog and digital I/O—all with extremely fast throughput for low-latency software monitoring. A single unified control panel provides settings for clock and sample rates, buffer sizes, individual signal levels for every input and output, adjustable +4dBu/-10dBV pad conrols and digital I/O control on up to four installed Delta cards. All controls are also easily accessible through most professional audio software applications for seamless integration and operation.
For the Hammerfall DSP System RME 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 MacOS, 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 (closed LAN to IEEE 1394.) The data transfer does not use Firewire protocol, but our own proprietary bus protocol. The supplied cable is 4.5 m (15 ft.) long, a cable length up to 10 m (33 ft.) has been successfully tested. The CardBus card does not provide power to the attached I/O-box. Therefore a hi-tech switching power supply is included.
