Please note that in order to achieve STEREO performance in either of the Mono modes, it will be
necessary to use two Plinius SA-250 Power Amplifiers - one amplifier each for left and right channels.
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.
