Ok, boys...Now you're allowed to laugh from the bottom of your heart and lungs.
It seems, according to my web-search, that this mic has a built in pre-amp requiring phantom power!!




At least, I did not find any other Superlux ribbon mic. I didn't find the manual yesterday, so this did not even occur to me.
So, when I go home I'll try it again with the phantom on...
Am I really this old and stupid??? (The crowd nods passionately)
I also found reviews that were a bit on the negative side, but anyways, the mic does fill a gap in my recording equipment.
