Cables into the back of our old church PA amp are male 5-pin plugs. About 1cm across with 5 round pins.
I know these can convert to regular XLR because that's how they are wired buti cannot access the wiring to see how.
Confusingly, these same 5 pin plugs seem to be used for audio as an XLR variant, and for lighting rigs. So it's making it harder to tell what adapter will or won't work... I want to connect a regular XLR from a microphone into a spare input so what requirements does an adapter have for this... Or should any 5-3 pin adapter be fine in practice?
