one of the easily obtainable ‘test discs’ to help you ensure both phasing and channel
orientation are correct. If in doubt, consult your Plinius dealer for advice.
To achieve a sound performance that is correctly aligned to your room, make sure all
of the leads carrying signals for the right channel loudspeaker are connected to the
right input to the amplifier from your preamplifier

There are essentially four different ways that you can connect your system
components to the PLINIUS SA-103 Power Amplifier:
1. RCA STEREO
2. RCA BRIDGED MONO
3. XLR STEREO
4. XLR BALANCED MONO
The following section explains how to use the SA-103 in RCA Bridged Mono and XLR
Balanced Mono configurations.

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 is not connected.
Next your loudspeakers are connected to both positive (+) channel output terminals.
So the positive red connection on your loudspeaker is connected to the red RIGHT
amplifier output, and the negative black connection on the loudspeaker should be
connected to the red LEFT 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.
