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.
