7. Inputs and Outputs

7.1 MADI Inputs

The rear of the MADI Bridge has six coaxial MADI inputs, available as BNC sockets. The sock-

ets are ground-free and separated from ground by capacitive coupling. This method prevents

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 10.1, MADI Basics.

7.2 MADI Outputs

The rear of the MADI Bridge 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 be 600 mVpp when terminated with 75 Ohm.

The two 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.

7.3 MIDI Input and Output

The rear of the MADI Bridge offers one MIDI input and output via two 5-pin DIN jacks. The MIDI

input can be used to remote control the MADI Bridge. The MADI Bridge sends out status infor-

mation via the MIDI output. All MIDI data at the MIDI input are passed on to the output, a

method known as MIDI Thru function. This way the MADI Bridge can be easily integrated (in-

serted) into existing cablings and setups.
