4 Mains power switch (1/0).
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 more
units are connected.
6 I.E.C. power supply socket with built-in fuse.
