Flying Arrays (continued)
The procedure for assembling arrays that will be flown is
similar to the one used to assemble ground stacks, except
that the order is reversed. Ground stacks are assembled from
the bottom up while flown arrays are usually assembled from
the top down.
Typically the RHANG101LA Flybar is used to fly an array
in both portable applications and permanent installations.
The cabinets built in attachment points are used mainly in
permanent installations.
To assemble a flown array:
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.
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.
4.
Lower the cabinet into position onto 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.
The heavy duty RHANG101LA Flybar supports arrays of up to 6 cabinets (4 array modules and 2
subwoofers). Arrays with 3 array modules provide 45

vertical coverage and 4 module arrays 60

.
Horizontal coverage remains constant at 90
