I want to buy an XLR to 1/4'' adapter to plug my microphone into in order to use it with my multi-effects before i run it into my audio interface. Will I need a 1/4'' to XLR adapter in addition to that to run it from my multi FX back into my audio interface? Or can i just use a normal 1/4 to 1/4 cable straight into my AI from the FX?
Yes you can.
Yes, you could get an adapter but you can also get an XLR to 1/4 cable aswell, search on google for then, they shouln't cost too much.
