ProFX12 Mixer

This diagram shows the left line level output of a Mackie ProFX12 mixer feeding inputs A and B of one Mackie HD1501 subwoofer. Two SRM450v2 powered loudspeaker inputs are fed from the A and B High Pass outputs from the subwoofer. 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.
