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
PLINIUSPLINIUS
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.
CONNECTING THE MAINS SUPPLY
Now that your Plinius SA-250 Power Amplifier is configured to your system correctly, the mains cable can
be plugged into the IEC connector on the back of the amplifier. Once the power is connected, flick the
main power switch on the front panel to the right. The power LED will pulse for ten seconds as the
internal microprocessor and soft start circuitry allow the amplifier internal voltages to settle. Once the
amplifier is at full voltage the power LED will stay lit, and the amplifier will be in mute. Depress the mute
switch to enjoy your new Plinius SA-250 Power Amplifier.
