Hi there. I have a macbook and have been recording vocals with the built-in microphone. Recently I purchased a Shure condenser mic to record on. I've been having trouble , though, because it doesn't seem to pick up the music very well. I've just been recording one track of me playing guitar and singing, and before it worked fine. Since I switched, though, the recording is very low. I have to turn the recording level up really loud and then that creates a lot of hissing in the background. I have the mic running on phantom power and it plugs from that directly into the space next to the headphone input. does anyone have any suggestions on how to get this (admittedly better than the built-in) mic to do as good of job?
