2.1.1 ANALOG CONNECTION
The ZES22 accepts and manages the devices of balanced and unbalanced audio.
The following diagrams explain how to connect different types of audio devices.
2.1.1.1 UNBALANCED SOURCE INPUT
To be able to connect an unbalanced source of 2 wires to the ZES22, you
have to connect the positive output of the unbalanced source to the positive I/O input of
the ZES22. Connect the ground input source with ZES22 main source, and unite the
negative input with the ground source of the ZES22 input. See Figure 3.
