XLR STEREO
Connect your processor or input signal to the two XLR inputs at the top of the amplifier back panel. Make
sure you connect the RIGHT XLR input and LEFT XLR inputs to the right and left outputs from your
processor respectively. Also make sure the XLR connectors click into place.
Next connect your loudspeaker wires to the output posts on either side of the rear panel. Connect your
right loudspeaker (ie the one on the right of you when seated in your normal listening position) to the right
output terminals, ensuring that the red positive (+) terminal is connected to the red terminal on your
loudspeaker. Do the same with the black or negative (-) terminals.
Now turn the ACS switch anti-clockwise so that it is in the XLR Stereo position. It is now safe to switch on
your amplifier.
TERMINATION QUALITY
Quality of the connections must be examined to ensure that high performance trouble free operation is
enjoyed. Check that the connections are tight but do not over tighten. If bare wires are used make sure
that no loose strands of wire short across the other terminals or the amplifier chassis. When using plugs
such as bananas, be sure to use good quality plugs with a firm fit.
BI-WIRING
Bi-wiring uses two pairs of loudspeaker cables for each channel loudspeaker. You will notice that the rear
panel of your Plinius SB-301 has two pairs of output terminals for this purpose. When using bi-wires,
connect each wire pair to a corresponding pair of binding posts (one cable to the top pair, one cable to
the bottom) paying special attention to positive (+) red and negative (-) black polarity.
PHASING (OR POLARITY)
It is important to achieve good stereo imaging in your listening room. By observing the wiring
instructions above, each Power Amplifier/loudspeaker combination should be in phase. If you experience
poor stereo image and/or a lack of bass, check that the loudspeaker wiring has been connected correctly.
We recommend that you use 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
processor or CD player etc. Signals for the LEFT channel should be wired in a similar fashion.
