5 Ground-lift (GND LIFT): this switch allows to lift signal
ground from chassis ground (but the chassis is still
connected to the safety ground).
This allows to lower annoying hums caused by 'ground
loops' when multiple units are connected.

7 Ground socket. It must be used only when the mains
cable is connected to an ungrounded socket, or if the socket
ground connection is unknown.
