HDA: 4 FLOWN HDA LOUDSPEAKERS
This setup is perfect for installs, touring systems, festivals and/or small stages...any venue requiring high
output with a 75–100 foot throw.
The left output from a mixer feeds the MAIN INPUT of the top HDA. The LOOP OUT of that HDA feeds the
MAIN INPUT of the next HDA. This daisy-chained array is repeated twice more to complete the quad HDA
setup. Here, the Array Mode switch should be in the ‘3-4’ position because four HDAs are in the array.
Alternatively, 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 boxes and 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 are
fl own utilizing an FB121 Flybar. In this array, subs may be on the stage to add more thump to the overall sound
system. Be sure to visit the next page if you are interested in fl ying subs. 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 cannot
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.
