Just to be clear on nomenclature, whether a signal is balanced or
unbalanced doesn't necessarily have anything to do with its level.
After all, the signal from most microphones are balanced, but are far
below +4 dB. Likewise you can easily have unbalanced signals at +4dB
and higher (like in modular synths), or lower (like an electric
guitar signal).
A balanced cable is one where there are 3 conductors, one of which is
ground and the other two are carrying the signal, but 180 degrees out
of phase with each other. This is so that any noise picked up in the
cable run can be cancelled out by inverting the out of phase signal
and mixing it with the in-phase signal.
An unbalanced cable is just 2 conductors - ground and signal.
Both of these assume we're talking about mono signals.
Hope this clears things up,
Chris
