How should my signal chain be setup? This is how it is now, Mic (Using a XLR cable)---->Presonus Bluetube (Using a TRS Cable)----->Presonus Bluemax(Using a funk cable, that goes from 2 1/4" to RCA's (Not sure if that is TRS or not) and then from RCA's I use a adapter from RCA to 1/8" to plug into my SantaCruz Turtle Beach. The reason I am asking is because I am having a noise issue (I have a thread below, this is Nutdotnet).
