there is one single point of connection between the signal ground connection and the mains supply
ground contact.
If the Public Address installation is composed of several equipment units, their chassis will probably be
joined, either by means of the ground terminal of the mains connection, or because they are fitted in a
rack cabinet.
If the ground connections are also joined by the signal circuits, it is advisable to remove the jumper
between the ground connection and the chassis from all the units except one.
