HDA: 2 HD1801 SUBWOOFERS AND 4 HDA LOUDSPEAKERS FLOWN
Similar to the hook-up diagram on the previous
page, this setup is perfect for installs, touring systems,
festivals and/or small stages...any venue requiring
a 75–100 foot throw. However, two subwoofers are
introduced to this setup, providing even low frequency
coverage for the fl own subs.
As in the previous hook-up diagram, the Array Mode
switch should be in the ‘3-4’ position because four
HDAs are in the array. Again, the top one or two
HDAs may be set to the ‘3-4 Long Throw’ position
if they have to cover an audience at a substantially
further distance than the bottom boxes. See the rear
panel descriptions on page 13 for more information.
It is possible to reproduce this exact same hookup in
stereo. Simply utilize the left and right main outputs
from the mixer to feed the main inputs of the top
subwoofers to mirror the rest of the system as
identifi ed above.
Another important aspect to keep in mind is the
rigging setup of loudspeakers. In this diagram, the
HDAs and HD1801 subwoofers are fl own utilizing an
FB121 Flybar. Note that each subwoofer requires its
own ACC–R180S rigging kit, as well. Refer to page
17 to view a table listing other confi guration
possibilities and pages 18 and 19 for more
information about rigging (and eyebolts).
Note that the HDAs AC power may be linked via the AC LOOP. Refer to page 6 for details on daisy-chaining
AC power.
Last, but not least, a VERY important warning: when the FB121 Flybar is used to suspend a system, it can not
retain a 10:1 design factor at certain pick points for the largest systems. Please refer to the array usage and
rigging sections, starting on page 17 and Appendix A on page 22 to review and run the Resolution software.
This predictive software is an invaluable tool in determining safety issues, weights and angles involved, coverage
and much more.
