This diagram shows the left and right line level outputs of a Mackie CFX12mkII mixer feeding input A of
two Mackie HD1501 subwoofers. The High Pass output A of each subwoofer then feeds the input of each
Mackie HD1521 powered loudspeaker. Experiment with the HD1501's polarity switch to achieve
optimum performance. Placement of the subwoofer relative to the full-range loudspeakers will also affect
performance. See page 10 for more information.
