Manual Owner’s

This diagram shows the left and right line level outputs of a Mackie Onyx 1640i mixer feeding input A of two Mackie HD1801 subwoofers. The Full Range output A of each subwoofer then feeds input A of another pair of Mackie HD1801 subwoofers. The High Pass output A of these subwoofers then feed the input of each Mackie HD1531 loudspeaker. Be sure to engage the Polarity Invert switch on the HD1801 subwoofers to optimize performance. See page 10 for more information.

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.
