Loudspeaker Connections
The SB-1180 is equipped with a four-position barrier strip with screw terminals that accept spade lugs or bare wire as large as 10 AWG. Inputs are
labeled

. Be sure to maintain consistent polarity from the amplifier to the loudspeaker’s input terminals. The parallel-wired output terminals
allow daisy-chain connection of additional loudspeakers; be sure to check the power amplifier’s specifications to avoid loads below the amplifier’s
minimum rated impedance.
