GROUND-STACKED, UPWARD FIRING ARRAYS
Applications such as covering stadium bleachers from the playing field may be addressed by installing the array
frames to the bottom of the array.
Up to four VRX932LAP loudspeakers may be locked together and ground
stacked using the VRX array frame kit, as shown.
WARNING: Do not ground stack more than four VRX932LAP loudspeakers
in one array.
When ground stacking VRX932LAP loudspeakers, use the VRX-AF array frame
as the base (as shown) by attaching the loose drop levers, included in the array
frame kit, to the lower rigging bar on the VRX932LAP loudspeaker. When
stacking the loudspeakers together, make sure each loudspeaker is locked
together. Be certain that the surface on which the system is to be stacked is flat,
stable and solid.
