i'm recording vinyls onto cassettes using a nakamichi cr-1a tape deck. i'm wondering what level i should let the recording "go up to". reading left to right on the tape deck it has numbers in green reading ( in db's) -30, -20, -10, -05, then in red numbers reading 0, +3, +5, +7. i made a couple recordings letting the numbers go up to +3 db but not over that and it sounds good. so what numbers should i let this go up to? any comments welcome. thanks
