I am still a beginner with ProTools and recording in general. I have an Mbox, and have make some decent recordings, but I just picked up a PRESONUS TubePre and now I'm having a very tough time getting my vocals to sound right. : ( I have an Audio Technica AT3035 Condenser mic going into the TubePre via XLR and then another XLR connecting the TubePre to Source 1 of my Mbox. I am using the Phantom power on the TubePre (and not on the Mbox), along with the "80Hz option" which I believe eliminates unwanted backround noise. The source on the Mbox is set to LINE. I have played with the GAIN and DRIVE on the TubePre, as well as the GAIN on the Mbox, as well as the ProTools standard Compressor Plug-in on a Bus track, (which is sending the compressed signal to a record-enabled track.) It seems like I can either get a compressed signal with too little dynamic range, or too much range with consequent distortion at peaks. It's very frustrating, because I feel like my vocals sounded better with the original set-up using just the Mbox and its Focusrites. Also, I am recording rap vocals in a foam-padded closet. Any tips? Ideas? They are badly needed! Thanks.
