Project Description


High Performance PCIe Card triple-MADI interface with ultra-powerful DSP providing full channel management, mixing, routing and on-board digital audio effects processing, for large-scale recording, post production, broadcast and live sound  applications. AES3 I/O, analogue monitoring output and MIDI I/O are included.


  • 3 MADI I/Os (2 x optical, 1 x coaxial) giving 192 inputs and 192 outputs
  • AES I/O
  • Analogue monitoring output
  • 4 x MIDI I/Os
  • Wordclock I/O


  • Newly-developed Hammerfall Pro Audio DSP core
  • Extremely low latency (computer-dependent)
  • TotalMix FX provides comprehensive on-board digital mixing
  • Unused channels require no processing overhead
  • Full range of on-board effects relieves DAW processing workload
  • MADI I/O 2 and/or 3 may be used for seamless redundancy backup with auto-switching
  • Configurable GUI with Hide feature allows only relevant channels to be veiwed
  • All normal sample rates up to 192 kHz


  • PCIe card; requires single slot with two lanes
  • Compatible with Mac OS X 10.5 and Windows 7/Vista/XP SP2

The RME HDSPe MADI interface is also available for applications which do not require multiple MADI I/Os or the additional on-board DSP functionality.


The RME HDSPe MADI FX interface card is a development of the HDSPe PCIe card, but provides greatly increased channel count and processing power due to a newly-developed DSP core. Three MADI I/O ports permita total of 192 inputs and 192 outputs of 24-bit audio at 48 kHz sample rates. Two of the ports use SC multi-mode optical connectors, the third BNCs.

The new DSP core is sufficiently powerful that the card may be used as a full digital mixing console with a wide range of audio FX (dynamics, EQ, reverb, delay, etc.) available to all channels. Fully flexible routing allows any input channel(s) to be routed to any output channel(s) at will, and the card may be implemented in multi-studio situations to act as a powerful MADI router/patchbay/format converter. Mixer functions are remotely controllable via MIDI using the industry-standard Mackie Control protocol.

A powerful feature of the card is auto-detection of MADI signal failure; in applications where the full channel count is not required, the extra MADI input ports may be used as redundant sources, and seamless switching will take place in the event of the primary input failing.

Control of the HDSPe MADI FX is via a configurable GUI, which can be set up so that only controls and metering of pre-determined sets of channels appear on-screen at any one time, the sets being changed with a single mouse click. All the facilities of a conventional analogue or digital hardware mixing console are available, including flexible stereo monitoring via analogue or AES3
