You can connect your System 220 speakers by using
spade lugs or “banana” connectors, or by removing 1/2"
of insulation from each wire end, twisting the strands
of wire together, placing the wire through one of the
post holes and screwing down the nut tightly.
It is important to observe polarity while making speaker
connections: red (+) terminals on the amplifier to red
(+) on the speaker, black (-) on the amplifier to black (-)
on the speaker. Look carefully at the wires you are using and note that one of the wires
in each pair is marked by either a different color, printing, ridges, or a thread inter-
twined with the wire strands. Conventionally, the marked wire is connected to the
red (+) terminal.

Whether your are connecting a complete System 220, or adding one speaker compo-
nent to your present system, the wiring should look like the diagram in Figure 2. Before
turning on the amplifier, be certain that no stray wire strands are touching across the
two terminals as this might damage your amplifier.
Finally, check the polarity of your front speakers by listening to some music. If the
sound seems hollow, spread out and has weak bass, recheck your connections for proper
polarity and reverse the connections if necessary.
