Sujet E-mu EIII XP et RME Fireface

See the Sample Management module and Main output Format (located under Special in the Master/Globals menu)
for more information

Professional AES/EBU equipment can be connected to the Fireface 400 thanks to the ‘Profes-sional’ format option with doubled output voltage. Output cables should have the same pinout as those used for input (see above), but with a male XLR plug instead of a female one.

This sets the stage for incompatibilities. Many older units are sticklers about what's what in each bit, and even though a given signal faithfully complies with the standard, some equipment will still reject it. Fortunately, many units are flexible and tolerant so simple resistor or transformer converters work. But be warned that a converter that works fine with one unit is no guarantee that it will work fine with all units.
