Guys, need an advice. I want to use pod X3 live as a fully fledged station to record vocals without processing at home with a dynamic and condenser microphones. I connected it through XLR input with Sm58 - if the gain is less than 75 percent, the signal is weak, if it`s more - it starts making a noise. I thought about buying an external vocal preamp of a type "ART TUBEMP". Is it possible to connect this preamp directly to the processor for this purpose? And through which input? Is this xlr input works as a line input of an audio card? Thanks a lot.
