Point Source Array Modules
Assembling Vertical Line Arrays
1.
Attach the RHANG101LA Flybar to the top cabinet
using the quick release pins. Note the bridle construction
which allows you to move the suspension bar laterally
and adjust the array’s tilt (aiming angle). Move the bridle
toward the rear of the cabinets for more tilt.
If you are using a VA / VAX15S subwoofer as a suspen-
sion platform, you will also need to remove the four feet
from the sub to allow it and the top array module to fit
snugly together.
2.
Attach the lifting device (chain hoist, fork lift, etc) you
will use to raise the cabinet into position to the flybar.
One commonly used arrangement is shackles and a
sling.
3
Raise the cabinet high enough to let you roll or slide
the next cabinet into position beneath it and
l
ower the
first cabinet into position over the second cabinet and
use the quick release pins and joining bars to lock the
two cabinets together. Move the joining bars from the
upper cabinet down into the lower cabinet.
5.
Repeat the procedure until the array is complete and
then lift (hoist) the array into position and secure it. Note
that you will need to use special connecting bars called
biscuits to join two unlike array modules, such as the 7.5
degree -7 and the 15 degree -15 modules.
Transitional wave guides are also available to assist in
shaping the array's horizontal coverage to fit the audi
-
ence area without introducing discontinuities between
the array modules.
