PLINIUS REFERENCE A-150

RCA BRIDGED MONO:
This option configures your amplifier to drive one loudspeaker from one unbalanced
signal fed to the red RIGHT RCA input. In bridged mono mode the only input made to your
preamplifier is to the red RIGHT channel RCA input. The black LEFT channel RCA input of the
Reference A-150 is not used in RCA Bridged Mono mode.
In Mono mode, the loudspeakers are connected to positive (+) red output terminals only.
The positive (+) connection on your loudspeaker is connected to the RIGHT positive (+) red
amplifier output. The negative (-) connection on the loudspeaker is connected to the LEFT
positive (+) red amplifier output.
DO NOT CONNECT ANYTHING TO THE NEGATIVE (-) TERMINALS. MAKING A
CONNECTION TO THE NEGATIVE (-) TERMINALS OF THE AMPLIFIER IN THIS MODE CAN
CAUSE SERIOUS DAMAGE!
You can still connect two loudspeakers using the lower positive (+) amplifier output
terminals. This is explained in the bi-wiring section previous. Now turn the ACS switch
fully clockwise then one position counter-clockwise so that it is in the RCA Bridged Mono
position.
XLR BALANCED MONO:
As with RCA Bridged Mono, this option configures your amplifier to drive one loudspeaker,
but from one balanced line input connected to the RIGHT XLR Input. In balanced mono
mode the only input made to your preamplifier is to the RIGHT channel XLR input. The LEFT
channel XLR input of the Reference A-150 is not used in XLR Balanced Mono mode.
In Mono mode, the loudspeakers are connected to positive (+) red output terminals only.
The positive (+) connection on your loudspeaker is connected to the RIGHT positive (+) red
amplifier output. The negative (-) connection on the loudspeaker is connected to the LEFT
positive (+) red amplifier output.
DO NOT CONNECT ANYTHING TO THE NEGATIVE (-) TERMINALS. MAKING A
CONNECTION TO THE NEGATIVE (-) TERMINALS OF THE AMPLIFIER IN THIS MODE CAN
CAUSE SERIOUS DAMAGE!
You can still connect two loudspeakers using the lower positive (+) amplifier output
terminals. This is explained in the bi-wiring section. Now turn the ACS switch fully counter-
clockwise so that it is in the XLR Balanced Mono position.
CONNECTING THE MAINS SUPPLY
Firstly, check that the mains supply voltage printed on the rear of this amplifier is similar to the
mains supply voltage in your area. If in doubt, please consult your Plinius dealer. Mains supply
power connection is via the plug-in lead supplied with your Plinius Reference A-150.
Check the wall outlet is switched OFF, then connect the local mains plug end of the lead to
the wall outlet. Check the Reference A-150 is switched OFF, and connect the IEC end of the
cable to the IEC socket at the back of the Reference A-150. With the cord fully connected,
switch the wall outlet ON.
