HD1801: 3-WAY SYSTEM - MONO SUBWOOFER WITH SRM450V2 LOUDSPEAKERS
Hookup Diagrams
This diagram shows the left and right line level outputs of a Mackie CFX12mkII mixer feeding inputs
A and B of one Mackie HD1801 subwoofer. Two SRM450v2 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.
