JBL array series - Page 4

Array Design and Applications
This section contains “tilt” guides showing the amounts of vertical “splay” angle available for different arrays by
selecting various combinations shackle mount and lift point locations. Since the arrays shown in these examples
..J
are suspended by a single point, guy lines will be required to stabilize the array from rotating.
Tilt Guide for 1 x 2 Array
Table 1 shows range of possible angles with shackle mount extending toward front of cabinet, Table 2 with
shackle mount extending toward rear of cabinet. A +5” to -28” range of aim angles are available from a single
hang point.
