As others have pointed out in subsequent posts, impedance balancing may not always work. It depends on the original circuit. If the output device is an op amp then it should work. All you need to do is connect the original output to the hot pin of the balanced connector. Then connect a resistor from the cold pin to analogue 0V. The value of this resistor should be equal to the output impedance of the original output. The hard part is working out the value of that output impedance and this is what depends on the particular circuit. Can you give us an example of a circuit you want to do this to?Thanks Ian for thinking about my original question.
I have to admit that I'm lost with all this extremely technical turn this thread has taken. Not complaining or anything. I know how fora work. I just can't follow the thread any more - I mean IC technology is beyond me. Maybe I will one day.
Could you please clarify with plain words what you mean by "simple impedance balancing". In my case (and I guess many other future and current readers) simpler terms help way more than precise technical terminology. For example instr. signal impedence (hi z), or line signal impedence etc.
