Scott you have to "PRE TEST" your Music & Vocals on the T2 to the MaX limits at full performance Volume WITHOUT CLIPPING to Achieve a good recording T2level.....there is no set percentage....each song, each part, each performer is different..before recording watch the meter levels until while playing/singing & raise or lower them until you just rarely see the meter clipping in the RED if at all .....if your recording a multitrack song you'll need to use the HDR level adjustment to balance BOTH levels. Also take a few practice recording for 30 sec or so....then go back, listen to make adjustments before you make the master recording all the way thru.
