- Unbalanced inputs are noisy because they are not grounded. If given the choice, always go with balanced inputs.

- actually, unbalanced cables _are_ grounded. (tip is hot, sleeve is ground).
unbalanced cables are *unshielded* which means that after a long cable run your signal will pick up more noise, and degrade your signal.
this is one reason why a microphone cable is balanced. because a microphone is such a low-level instrument, a balanced cable will tame cable noise, and keep signal integrity.
line level instruments are much hotter, so an unbalanced cables work fine (of course for a short cable run)
if a longer cable run is necessary, you would use a direct box to convert an unbalanced cable to a balanced run.
hope this helps a little.
