The left and right line-level outputs from a mixer feed the left and right inputs of the first Mackie
SRM1801 powered subwoofer. The inputs are summed in mono to play in the subwoofer, but this does
not affect the full-range or high-pass outputs, which remain fully stereo. The left and right full-range line-
level outputs of this subwoofer feed the left and right inputs of the second Mackie SRM1801 powered
subwoofer. The high-pass outputs or full-range outputs of either subwoofer could feed the other powered
loudspeakers in your system.
The left and right line-level outputs from a mixer feed the inputs of a pair of Mackie SRM1801 powered
subwoofers. Their respective full-range outputs feed the inputs of another pair of Mackie SRM1801
powered subwoofers. The high-pass outputs from the second set of subwoofers then feed the inputs of a
pair of Mackie SRM450v2 powered loudspeakers.
NOTE: It is highly recommended that you use straps to secure your loudspeakers for stacked scenarios
such as this one. Be sure to loop a strap through each handle going down each side of the cabinet setup,
as shown above.
