Multiple ways to fly the X12TE-GRID
X12TE-GRID can be flown in four (4) different ways—with a single grid pick point, with a single
grid pick point plus a pullback to the venue, with two (2) grid pick points, and with two grid
picks points plus a pull-up to the grid. Additionally, the loudspeakers may be attached to the
grid in three different positions. In LAPS 3, the user must choose which way the grid will be
flown, plus the attachment position of the loudspeakers.
Figure 6.12: Flying the X12TE-GRID
Single grid pick point:
With the loudspeakers attached in the A position (2a), a large section of the grid extends
behind the rear of the loudspeaker, enabling the maximum amount of down tilt.
With the loudspeakers attached in the B position (2b), a portion of the grid extends both
behind and in front of the loudspeaker, enabling moderate tilt both up and down.
With the loudspeakers attached in the C position (2c), a large section of the grid extends in
front of the loudspeaker, enabling the maximum amount of 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 should be 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 with the loudspeakers attached in the
A position (2d).
A pullback to the venue can also be used with the loudspeakers attached in the B position
(2e) or in the C position (2f). Choose a grid pick point near the front of the grid. This will tilt
the array up slightly, which will make it easier to build because the bottom of a flown box will
be a closer match to the top box on a dolly stack.
