PLINIUS REFERENCE A-150
Rear Panel Functions
This panel incorporates all the terminals for connecting the input signals from your
preamplifier and output to the loudspeakers and mains supply. Be sure you understand
your system’s requirements fully before you make any connection to this amplifier.
1. INPUT TERMINALS
Input terminals for your Plinius Reference A-150 power amplifier are easily accessible and
fitted near the top centre area of the rear panel.
RCA INPUTS: These standard RCA terminals are for use with unbalanced signals from most
signal sources such as audio preamplifiers.
XLR BALANCED INPUTS: XLR connectors fitted to this amplifier are for use with balanced
line signals from audio preamplifiers. Balanced signals are carried via a three way cable that
connects all three pins at each end of the interconnect cable.
The XLR input pin configuration used in all Plinius products is as follows:
PIN 1 to GND
PIN 2 to +Signal
PIN 3 to -Signal
NOTE: Because of the way balanced XLR inputs are configured it is not
possible to connect both XLR and RCA at the same time.
