Thank you to Helmut Frequenzwaschl first of all for sending me the link and thanks also to Markus Neuner and Bensons Funk for the revised details of the microphone socket of the AE 5900. This is the correct wiring for those wanting to make microphone adapters etc

It appears there is an issue with the manual showing wiring so this one is the most up to date and working one for the microphone adapters.

And for those who need the English language version
