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.

CONNECTING THE MAINS SUPPLY

Now that your Plinius SA-103 Power Amplifier is configured to your system correctly, the mains cable can be plugged into the IEC connector on the back of the amplifier. Turn on the power switch on the rear panel. 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. Press the mute switch to enjoy your new Plinius SA-103 Power Amplifier.
