The input connection depends on two factors, the first is the type of input signal
balanced or unbalanced, and the second the ground configuration of the sound source
(floating or ground-referenced). The next pictures show some of the different possibilities of
connection, relying on the type of input signal, balanced or unbalanced and according to the
ground configuration of the equipment (floating or ground-referenced).
In the next diagrams, we use the following symbols:
Sound source with mains cord without ground connection.

UNBALANCED INPUT:
This type of connection will be used when the sound source does not provide
balanced output. If it’s possible it is better using the connection type 1
