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 shows 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.
Sound source with mains cord with ground connection.
Sound source with the EARTH-LINK OFF.
Sound source with the EARTH LINK ON.
UNBALANCED INPUT
This type of connection will be used when the sound source doesn't provide balanced
output. When possible, employ the connection type 1.
