INPUT TERMINALS
Input terminals for your Plinius SB-301 Power Amplifier are easily accessible and fitted to the top centre
area of the rear panel. A brief summary of connection possibilities is listed below, while a more detailed
explanation follows later in this instruction manual.
RCA INPUTS LEFT & RIGHT: These standard RCA terminals are for use with unbalanced signals from
most signal sources such as audio preamplifiers or home theatre processors.
XLR BALANCED INPUTS LEFT & RIGHT: XLR connectors fitted to this amplifier are for use with balanced
line signals from audio preamplifiers or home theatre processors. Balanced signals are carried via a three
way cable that connects all three pins at each end of the interconnect cable.
The XLR pin configuration used in all Plinius product is:
PIN 1 to GND
PIN 2 to +Signal
PIN 3 to -Signal
NOTE: Because of the way our XLR and balanced inputs are configured it is not possible to connect both
XLR and RCA at the same time.
AMPLIFIER CONFIGURATION SELECTOR (ACS)
The Amplifier Configuration Selector (ACS) is a unique switching method that exploits all of the
operational features of your Plinius SB-301 Power Amplifier. By using this switch it is possible to operate
your amplifier with either balanced or unbalanced signals.
