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
cross 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 SA-Reference has two pairs of output
terminals for this purpose. When using bi-wires in a STEREO installation, 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. With a MONO setup remember that your speaker wires must use the red
positive (+) output posts ONLY. Connect one speaker cable to the top positive (+) red
binding posts, and the other speaker cable to the lower positive (+) red binding posts.
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 preamplifier or cd player etc. Signals for the left
channel should be wired in a similar fashion.
BRIDGED/MONO CONNECTIONS
There are essentially four different ways that you can connect your system
components to the PLINIUS SA-Reference Power Amplifier:
1. RCA STEREO
2. RCA BRIDGED MONO
3. XLR STEREO
4. XLR BALANCED MONO
