” Attach the rear lug of the bracket to the Ground Stack hole in the cabinet's rear mounting plate. Secure with a Rigging Pin.

” Using the rear adjustment knob, set the tilt angle to the angle defined by DISPLAY 2.3. The angle can be seen by observing
the calibration hole at the right-hand side.
” Lift the four-cabinet array and suspend it from the truss or scaffold pole by the trigger clamp. How this is best achieved will
depend on the venue and other circumstances on the day. The easiest solution, wherever possible, is to lower the scaffold
pole or truss section from which the array is to be flown to a sensible working height, attach the array and raise the pole/
truss back up to the height specified by the DISPLAY prediction. If this option is not available, a mechanical hoist (e.g.,
Genie or picker) or adequate manpower can be employed. Ensure that the T-clamp is tightened.

” If easy access is available to the array at its flown height, it is probably better to leave connecting the cabinets up until the
array has been raised to height, as hanging cables may constitute a hazard. However, if it is easier to connect up at ground
level, perform this step next.
” As the array is being raised, and as the cabinets reach a suitable height, set each of the inter-cabinet angles in turn. Refer
to the data from the DISPLAY software prediction.
” The correct height for the array will be defined by the DISPLAY software prediction, measured from the stage or other floor
to the bottom of the lowest cabinet.
