HDSP 9652 is the long-awaited successor of the well-known PCI card Project Hammerfall (DIGI9652). Like the original Hammerfall, HDSP 9652 offers 3 x ADAT optical I/O, ADAT-Sync In, SPDIF I/O and word clock I/O. On top, there are 2 MIDI I/Os and TotalMix, a DSP-based real-time mixer/router.
The HDSP 9652’s Secure BIOS Technology allows to perform hardware updates via software/driver without any risk. And thanks to its unique ’Zero CPU Load’ technology Hammerfall DSP guarantees highest performance and lowest latency on both notebooks and desktops!
Hammerfall also allows to connect Analog Expansion Boards (AEB). Two internal ADAT inputs and two internal ADAT outputs allow you to realize up to 16 analog inputs and 16 analog outputs directly inside the computer.

3 x ADAT digital I/O, based on RME’s reliable Bitclock PLL

1 x SPDIF digital I/O, based on RME’s reliable DIGI96 technology

1 x Breakout cable for coaxial SPDIF operation

1 x Word clock I/O (BNC) on included expansion board

1 x ADAT Sync In (9-pin D-type) for sample accurate transfers

2 x MIDI I/O, 32 channels high-speed MIDI via breakout cable

HDSP Meter Bridge: freely scalable level meters, peak- and RMS calculation directly in hardware

TotalMix: 1456 channel mixer with 40 bit internal resolution

S/MUX poured in hardware: 12 channels 96 kHz/24 bit for record and playback on ADAT optical

...and numerous other features found already in the Hammerfall series. And all this for an unbeatable price!
