PLINIUS REFERENCE A-150
3. OUTPUT TERMINALS
Output connections for the loudspeakers are provided on the left and right hand side of the
rear panel. Two parallel pairs of binding posts for each channel are fitted – these provide
ease of use with bi-wiring and multiple cables requiring a large contact area.
4. MAINS SWITCH
This heavy-duty rocker switch in the centre of the panel turns the Mains/Line Power to
the amplifier ON or OFF. An LED in the centre of the front panel indicates that the power
is on. When first switched on the power LED will vary in brightness for ten seconds – this
is an initialisation sequence, after which the power LED remains lit. The amplifier draws
a moderately high current when switched on. Despite the “Soft Start Circuit” within the
amplifier reducing current demand on the mains as the amplifier is switched on, it is not
good practice to rapidly turn the Mains switch on and off repeatedly.
5. 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.
6. REMOTE TRIGGER SOCKET
In order to integrate more effectively into a home theatre or multimedia system, the Plinius
Reference A-150 has a remote trigger socket on the rear panel. By connecting a preamplifier
or processor with a remote trigger output signal to these terminals, the Reference A-150
can be put in and out of Class AB/Mute by the component to which it is connected. When in
Class AB/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.
7. 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. Note that when using
Balanced XLR inputs, the ground lift switch should always be set to ‘chassis’.
