CHAPTER 9: GROUNDSTACKING WITH THE MG-MINA/LINA/750-LFC GRID
The MG-MINA/LINA/750-LFC grid can safely groundstack up to six LINA loudspeakers. The LINA at the bottom of the stack
attaches directly to the grid with its GuideALinks and is secured with the quick-release pins (0.25 in x 0.90 in, black button
with 6 in lanyard, PN 134.036) included with the grid. The configuration of the rear GuideALinks for the attached LINA deter-
mines its tilt. The groundstacked array can be curved by adjusting the rear GuideALink positions of the units stacked above
the bottom LINA.
CAUTION: Always use the quick-release pins included with the MG-MINA/LINA/750-LFC grid to secure its
links, as well as to secure groundstacked LINAs to the grid. Do not use the quick-release pins included with
LINA in the grid as they are shorter and will not lock in place.
NOTE: While it may be possible to safely groundstack up to seven or eight units with MG-MINA/LINA/750-LFC
grid, you should only do so if the stack’s center of gravity is near the center of the grid. Groundstacks with
extreme tilts place the center of gravity further from the grid’s center and may be at risk of tipping.
CAUTION: To secure groundstacked arrays, particularly in outdoor situations, use tie downs or weights with
the grid, as well as a safety system on the array.
