Mixer

This diagram shows the left line level output of a Mackie 1604-VLZ3 mixer feeding input A of one Mackie HD1801 subwoofer. Two HD1521 loudspeaker inputs are fed from the A and B High Pass outputs from the subwoofer. Experiment with the HD1801’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.
