Legacy Silverscreen II Owner's Manual page 12

At the rear of each of your loudspeakers you will find a terminal plate housing
two rows of jumpered binding posts. The upper row is the input to the "satellite"
portion of the speaker. The lower row is the input to the "subwoofer" portion of
the speaker. When left in place, the factory-installed jumper bars allow the
speaker to be driven with a single channel of amplification. (If biamping, or
biwiring, be sure to remove the jumper bars.
Connect each channel of amplifier to a loudspeaker via the five-way gold binding
posts provided. Dual banana plugs or gold plated spade lugs are recommended
means of termination. Be sure that you observe polarity when making the
connections. The positive (+) terminal of the amplifier should be connected to the
positive terminal of the loudspeaker. The negative (-) terminal of the amplifier
should be connected to the negative terminal of the loudspeaker.
