This is interesting, thanks for raising the issue. I had assumed that the
deck had its own preamp with a digital gain control.

What if your source is too LOW ?

If you're going to do this properly, you need to use an A/D with more
resolution and a wider input voltage range, so you can use some of the extra
bits for overload margin, and some to provide digital "gain". Perhaps they
do this already ?
