User Manual

SteadyClock . RME’s unique jitter suppression technology guarantees perfect sound quality throughout,
making the device completely independent from the quality of external clock signals. Due to the highly efficient
jitter reduction, the DA converter operates independently from the quality of the external clock signal, as if they
are working with internal clock all the time. Moreover, a clean signal with minimal jitter is available on all digital
outputs.
SteadyClock allows the HDSPe MADI FX to control the sample rate freely on its own. The settings dialog includes
a direct choice of the video and audio world’s most often used sample rates.
ICC . Intelligent Clock Control not only displays every clock status, but will also retain the last valid input sample
rate in case of failure of the external source. Other renowned RME technologies like SyncCheck offer a quick
detection of clock problems.
DIGICheck . The card comes with RME’s unique software tool box for metering, testing, measuring and analyzing
digital audio streams. On Mac OS X provides unique functions and features of the spectral analysis of the data
calculated in hardware level right through to sophisticated multi-channel level meter. On Windows, an additional
multi-track recorder and the display of playback data from an audio software are also available.
