I do record in my T2 instrumental music, but since I do not sing, I have not experience what you do, but, regarless, if you do record in a lower level, in digital recording always there is the "NORMALIZE" function, this makes the level to be maximized without the chance of saturating or cliping, that is what is mostly use to "level" a CD, remember that in the early CD recordings, some tracks sounded in a Low level, then others high?, this is what you can use, so, my advise is to record at a Lower level, so you do not overload the signal in the recording procedure, when finish, then use the Normalize function and that is it.
I hope it helps.
