Here is my current chain: Mic > firepod or tascam us122 > garageband I want to add a compressor to this just for vocal tracking but I don't know how or where it goes in the chain. I am getting an FMR Audio RNC. I'll attach the figure of the back of the unit so you can see the various inputs. In my mind I that the chain would be, mic > compressor > firepod or tascam > garageband but I don't see any XLR connection on the RNC. So where does it fit in? Any help?
