RME HDSPe MADI FX 390-Channel PCIe Card
The RME HDSPe MADI FX puts 390 audio channels on a PCI Express card, with two optical and one coaxial MADI port, AES/EBU, word clock, MIDI, and a headphone output.
MADI Ports
The two optical ports use SC connectors in multimode, and the coaxial port uses a 75 Ohm BNC. Together they carry 192 input and 192 output channels at 44.1 and 48 kHz, 96 at 96 kHz, and 48 at 192 kHz, and the card converts between optical and coaxial MADI on its own.
Seamless Redundancy Operation treats the three MADI receivers as one 64-channel input. When the active input fails, the card takes the audio from one of the other two with no reclocking, keeping the interruption to a few samples.
AES/EBU, Word Clock, MIDI, and Monitoring
A breakout cable carries an AES/EBU input and output and a MIDI I/O. The AES/EBU connections serve a stereo converter, an effects unit, or sync. Each MADI port also carries a virtual MIDI port, and MIDI over MADI remotely controls RME MADI devices at the far end of the cable.
The word clock I/O has switchable termination, and SteadyClock takes a clean clock straight from the MADI signal, so long MADI runs need no separate clock line. The stereo headphone output on a 6.3 mm jack also works as a line output, and TotalMix can send any input, track, or submix to it.
Installation, Mixing, and Latency
The card needs one PCIe slot and one free slot opening on the case for its included BNC expansion board. It runs on Windows and Mac with buffer sizes from 32 to 8192 samples, and unused channels switch off automatically so they take no processing power.
TotalMix FX gives the card a 4096-channel mixer and router, with each channel routed on its own at its own level. Its DSP adds 3-band EQ, low cut, reverb, echo, compressor, expander, and auto level, and Room EQ adds a 9-band parametric EQ with delay and volume calibration. Unused channels can be hidden, with hide setups saved and recalled in one click.
