The TC Connect 48 appears to have 62 db of maximum preamp gain, which is a bit less than optimal for an SM58, but workable. Add digital gain after the track is recorded to get the level you want. Remember, you should be aiming for RMS (average) levels around -18 dBFS with peaks not to exceed -6 dBFS when tracking. You shouldn't try to get close to 0 dBFS until you're through mixing and into the mastering stage.
thanks for your reply Fran,
since the first post i did a bit of experimenting and found if i used an XLR lead on the sm58 mic strangely i get the extra boost i was looking for even though its not a powered mic ,
im not well up on db figures, i usually just do things visually when setting the signal as my old sound card had a gain trim ,im still sussing things out with the konnekt , anyway, thanks for the info on ideal db headroom and amp gain, that is useful . I think id better do some more reading instead of pestering the forum in future.
