outer holes may be used for lifting as a two-point lateral hang, often useful to prevent twisting
of the array. In this situation, lifting and suspension lines must not exceed 15° from vertical
and both points must be lifted equally so the array is never more than ±5° from horizontal
during the lift.
!
Caution!
Do not lift an array by attaching directly to the sidearms.
Lift with the supplied spreader bar(s) only.
The compact grid sidearms are usually attached with the excess overhang at the rear to allow
for greater down-angle possibilities. For situations where more up-angle is possibly required,
such as covering a high balcony in a theater, the grid can be reversed with the excess grid
length overhanging the front of the array.
Installing the X12TC-GRID to an X1 or X2 loudspeaker
When the compact grid with its single spreader bar is used, the trim angle of the array is
determined by the front-to-back attachment position of the spreader bar. This information is
provided by LAPS 3, a function of the array makeup and desired vertical aiming.
!
Caution!
Verify each end of the spreader bar is pinned in the same number hole on both sidearms.
Ensure the pins attaching the grid sidearms are fully locked into the holes in the ends of the
spreader bar.
Notice!
Using the PICK HERE alone requires a tie-off to stabilize the horizontal rotation of the array.
Notice!
Before flying the array verify the captive twist lock pins are fully engaged in the rigging (no
red showing between the pin knob and the box).
To install the X12TC-GRID, do the following:
1.
Pull and twist two (2) captive twist lock pins (A) on one side of the loudspeaker.
Two (2) captive twist lock pins are locked in the retracted (Open) position.
2. Guide one (1) sidearm (B) into the rigging tubes until it is fully seated in the V-blocks.
