The RME HDSPe MADI FX PCI Express Card is a unique audio system capable of transferring digital audio data directly into a computer, from any device equipped with a MADI interface. Based on the common professional AES/EBU standard, the HDSPe transmits 64 audio channels with a single line and embeds MIDI and RS232 signals invisibly into the data stream.

The RME HDSPe MADI FX PCI Express Card marks a new milestone both in the history of audio interface cards in the past two decades and within the long series of outstanding RME devices. Never before has such a high-performance multi-channel audio system existed.

The RME HDSPe MADI FX features 390 audio channels! Three MADI I/Os - two optical and one coaxial are accompanied by one AES/EBU I/O and one analog monitoring output. To complete the feature set, a Word Clock connection and four MIDI I/Os were added. The complete technology and connectivity are highly integrated into the smallest possible amount of space - typical for RME. Only one PCIe slot is required on the motherboard, plus one free slot opening on the case.

To guarantee RME's unique low latency performance with such a huge amount of audio channels, the RME HDPSe MADI FX introduces a newly developed modular Hammerfall Pro Audio Core. The high-tech core will process three times as many channels as the channel count of the previous MADI flagship, while actually reducing the system load and enabling ultra-low latencies down to 32 samples on modern computers.

A sophisticated new efficiency technology will automatically deactivate currently unused channels, so that they require no processing power or bandwidth. A simple stereo playback will not require any more performance than from a standard stereo audio card - despite the use of a professional multi-channel system with almost 400 channels.

The new core technology is accompanied by a special version of TotalMix FX, which allows using the enormous channel count in an efficient and practical manner. The addition of numerous performance optimizations ensures that the 4096-channel mixer of the MADI FX responds just as smoothly as its 1800-channel counterpart in the Fireface UFX. A new and faster DSP allows for a greater number of EQs and compressors.

An innovative new layout of TotalMix enables ergonomic handling of the enormous number of channels. A special option makes it possible to visually hide unused channels. Complete "Hide setups" can be saved at any time, and switched with a simple mouse click, for example between the channel view of the drum mix and the full band setup.

The 192 kHz RME effects engine allows latency-free monitoring with numerous effects like EQs, Compressors, Reverb, and Echo rendered directly on the hardware of the card, independent from the DAW software in use.

The integrated TotalMix matrix conveniently allows the use of the card as powerful MADI router. Unlike most other router solutions, each channel can be routed individually - even with separate level settings for each routing. The unparalleled flexibility of TotalMix can turn the most exotic applications into practical reality.

The RME's unique Seamless Redundancy Operation uses the cards 3 MADI receivers to provide professional users with state-of-the-art fail safe operation. In SRO mode the card operates as single MADI input device, recording up to 64 channels. As soon as the current input fails the audio data received from one of the other two inputs is used. The audio data is not interrupted when switching to another input and the card can use not only one, but two more sources for redundancy. No relocking and synchronization to a different clock source is required, and the interruption caused by the external failure is minimized to a few samples.

The card also features SteadyClock, RME's active jitter suppression and the unique professional meter and analysis toolbox DIGICheck - including EBU R128 metering - as well as nearly identical operation of the card under Windows and Mac OS.

    Pricey, but worth it

    Fantastic card. A huge amount of I/O, super stable, integrated FX (great for "confidence reverb on a monitoring path) and extremely flexible routing. I have heard about some problems with PT compatibility but it seems to work great with PT11 running under windows even with all I/O enabled. If you're using multiple different models of converters you will have to account for different conversion latency, but this has been a minimal problem so far.

What We Think


The RME MADI FX is the heart and soul of my studio. Nothing gets done without the MADI FX. The exoansive MADI I/O gives me more inputs and outputs that I could ever need, and the MIDI, AES, and Analog connections add even more functionality. Thanks to the MADI FX card, I have the workflow and functionality of a large format console, without the cost, footprint, or upkeep. I also have full access to all analog IO all the way up to 192kHz sample rate. Further I use the AES which gives me a fool proof set up for any and all track, editing, mixing, and mastering needs. On top of that, I get TotalMixFX, which is by far the most powerful virtual routing software out there. There is nothing you can't do with TotalMixFX. Can mixes, multing, presumming, parallel processing, saving presets for tracking, editing, mixing, and master - really anything you can think of. RME is well regarded for their build, sound, and functional quality. My studio would not be what it is, and what it is capable of, if it was not for RME and the MADI FX PCIe Card.
