[...] If you have a bipolar
output with equal voltages of opposite polarity with respect to ground
and at the same source impedance, and connect this to a differential
input, you have a balanced connection. If you then tap off the "high"
side and connect that to another input, you've unbalanced your
connection.

Thanks! The new (to me) lesson here is that it is the whole circuit that is
balanced or unbalanced, rather than any given output or input by itself.
