22. Connections
22.1 MADI I/Os
The BNC input's ground-free design is built according to AES10-1991. The input impedance is
75 Ohm. It will operate error-free from about 180 mVpp on.
The optical input and output uses a FDDI (ISO/IEC 9413-3) compatible optical module, accord-
ing to AES10-1991. More information can be found in chapter 29.1, MADI Basics.
The front of the I/O box has a push button acting as input selector, switching the MADI input
from coaxial to optical. The currently active input is indicated by a lit LED.
The BNC output is built according to AES10-1991. The output's impedance is 75 Ohm. The
output voltage will be 600 mVpp when terminated with 75 Ohm.
22.2 MIDI
The MADIface has a virtual MIDI port. MADI MIDI In (1) and MADI MIDI Out (1) receive and
transmit MIDI data via MADI. This allows for a direct communication between systems with
HDSPe MADI cards or MADIfaces. Additionally MIDI data can be transmitted from/to other RME
devices with MADI ports, and both can be MIDI remote controlled without any additional line or
cabling between computer (MADI card) and unit.
