Mackie HDA Owner's Manual page 10

Similar to the hook-up diagram on the previous page, this is the perfect setup for any venue where the
audience is level with and sloping upward from the stage and PA. For example, a bowl, a shed or a gym with
bleachers. However, a subwoofer is introduced to this setup, adding a lot more thump to the system.
The left output from a mixer feeds INPUT A of a Mackie HD1801 powered subwoofer. The HIGH PASS
OUTPUT A of the subwoofer feeds the MAIN INPUT of a Mackie HDA powered loudspeaker. The LOOP OUT of
that Mackie HDA powered loudspeaker feeds the MAIN INPUT of the next Mackie HDA powered loudspeaker.
The HDAs reproduce the mid-to-high frequencies in mono, and the sub provides the low frequencies in mono.
Since three HDAs are used, the Array Mode switches should be in the '3-4' or '3-4 LONG THROW' position.
It is possible to reproduce this exact same hookup in stereo. Simply utilize the left and right main outputs from
the mixer to feed INPUT A of each HD1801 and mirror the rest of the system as described above.
Another important aspect to keep in mind is the rigging setup of loudspeakers. In this diagram, the HDAs are
ground stacked on a subwoofer utilizing the ACC–R180S rigging kit for the HD1801. This system may also be
fl own utilizing the FB121 Flybar, with the HD1801 powered subwoofer on top. See the next two pages for fl ying
HDAs, page 17 to view a table listing other confi guration possibilities and pages 18 and 19 for more
information about rigging.
Note that the HDA's AC power may be linked via the AC LOOP. Refer to page 6 for details on daisy-chaining
AC power.
