Björn Eriksson:
I am not sure I want to touch the machine now again... but probably when I come home again around 5pm I will switch over to the outside mike... and hopefully it will still work.
hi Björn,
i think i had a similar thing once with the provided mic, not sure. but i think i eliminated it by connecting all metal shields, i.e. connect the mic's ground/case with the one of the cable.
best, udo
