CONNECTIONS FOR STEREO OPERATION CONTINUED
CONNECT the RIGHT hand loudspeaker to the RIGHT CHANNEL OUTPUT terminals on the
amplifier. Connect the LEFT hand loudspeaker to the LEFT CHANNEL OUTPUT terminals.
Connect the Positive (+) or Red loudspeaker terminal to the + (Positive) terminal on the amplifier.
Connect the Negative (-) or Black loudspeaker terminal to the - (Negative) terminal on the amplifier.
Repeat this process for each loudspeaker.
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 a 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 /
loudspeaker dealer for advice.
