Hi, I have a set up that could be connected
to pa the sound while recording and such .
Only sometimes i want to have it on the in socket also while it is
also going out so effect feedback sqeek.
same goes for mic and pa it wil feedback .
so i gues i can not use in and out at the same time
unles i do it on systems not otherwise inter connected.
use headphones but they do not sound like pa .
