Multiple ways to fly the X12TC-GRID

X12TC-GRID can be flown in two (2) different ways—with a single grid pick point and with a
single grid pick point plus a pullback to the venue. Additionally, the grid has two (2)
orientations forward and reversed. In LAPS 3, the user must choose which way the grid will be
flown, plus the orientation of the grid.
Figure 6.11: Flying the X12TC-GRID
Single grid pick point:
In the forward orientation (1a), a small section of the grid extends behind the rear of the
loudspeaker, enabling more down tilt.
In the reversed orientation (1b), a small section of the grid extends in front of the
loudspeaker, enabling more up tilt.
Choose the pick point on the grid to achieve the desired angle as reported by LAPS 3.
Single grid pick point with a pullback to the venue:
A pullback to the venue is used when more down tilt is required than can be achieved by a
single grid pick alone. The X12PU-BGK is used at the bottom of the array.
The most common orientation would be to use the grid in the forward position (1c).
The grid can also be used in the reversed orientation with a pullback to the venue (1d). The
purpose of the pullback is to enable greater down tilt.
Choose a grid pick point near the front of the grid. This tilts the array up slightly, which makes
it easier to build because the bottom of a flown box will be a closer match to the top box on a
dolly stack.
