6. Inputs and Outputs
6.1 MADI Inputs
The rear of the MADI Converter has six coaxial MADI inputs, available as BNC sockets. The
sockets are ground-free and separated from ground by capacitive coupling. This method pre-
vents ground loops and other distortions by potential differences between the connected units.
Note that the transmission at the receiver still operates unbalanced.
The BNC input's ground-free design is built according to AES10-1991. The input's impedance is
75 Ohm. It will operate error-free from about 180 mVpp.
The two optical inputs use a FDDI (ISO/IEC 9413-3) compatible optical module each, according
to AES10-1991. More information can be found in chapter 7.1, MADI Basics.
6.2 MADI Outputs
The rear of the MADI Converter has six coaxial MADI outputs, available as BNC sockets. The
BNC outputs are built according to AES10-1991. The output impedance is 75 Ohm. The output
voltage will around 400 mVpp when terminated with 75 Ohm.
The six optical outputs use a FDDI (ISO/IEC 9413-3) compatible optical module each, accord-
ing to AES10-1991. More information can be found in chapter 10.1, MADI Basics.
6.3 MIDI Input and Output
The rear of the MADI Converter offers one MIDI input and three MIDI outputs via 5-pin DIN
jacks. All MIDI data at the MIDI input are passed on and copied to the outputs, a method known
as MIDI Thru function.
