GROUND LIFT SWITCH
This switch is located adjacent to the Mains Input Socket, and allows the signal ground to be
disconnected from the chassis. In some installations a hum loop may exist due to duplicate ground paths
from different equipment. Use this switch to remove the connection from 0V to ground thus allowing
some flexibility in your particular set-up.
MAINS POWER CORD IEC CONNECTOR
This connector is where the mains supply cable from your wall connects to the amplifier. You will notice
that a fuse holder is mounted within this connection, and it holds a mains fuse to provide surge and
overload protection for your amplifier.
REMOTE TRIGGER TERMINALS
In order to integrate more effectively into a home theatre system, the Plinius SA-301 has remote trigger
terminals fitted to the rear panel. By connecting a processor with a remote trigger signal to these
terminals, the SA-301 can be put in and out of Standby/mute by the processor to which it is connected.
When in Standby/mute the amplifier draws less current and will operate at minimum temperature. The
output relays are also open, disconnecting the loudspeakers. This may be of advantage in a multi-
amplifier and/or remote installations. The Standby/mute mode can only be activated via the remote
trigger terminals. Polarity of the connections to the remote trigger is not important.
