CHAPTER 4: QUICKFLY RIGGING
MG-MINA/LINA/750-LFC GRID
The MG-MINA/LINA/750-LFC grid (Figure 22) flies LINA
arrays of up 16 cabinets at a 5:1 safety ratio. The grid, which
can also be used for groundstacking arrays, accommodates
a variety of pickup configurations with four side pickup
points and 11 center pickup points.
NOTE:
Additional load ratings are possible.
Use MAPP to verify load ratings.
NOTE:
For complete information about
configuration and load ratings for the
MG-MINA/LINA/750-LFC grid, as well as other LINA
rigging accessories, refer to the MG-LINA/750-LFC
Assembly Guide (PN 05.207.101.02) available at
www.meyersound.com.
Figure 22: MG-MINA/LINA/750-LFC Grid
The MG-MINA/LINA/750-LFC grid has four captive links,
two per side, that attach to the top LINA in flown arrays. The
configuration of the links and orientation of the grid (for
either maximum uptilt or maximum downtilt) determine the
angle of the attached LINA. The grid links are easily stowed
for transport and groundstacked configurations.
The MG-MINA/LINA/750-LFC grid includes eight (0.25 in x
0.90 in) quick-release pins: four for securing the four grid
links, and four for securing LINA groundstacks to the top of
the grid.
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 ground-
stacked 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.
TIP:
The MG-MINA/LINA/750-LFC grid can
travel installed on top of LINA stacks.

MG-MINA/LINA/750-LFC Grid Orientations for
Flown Configurations
The orientation of the MG-MINA/LINA/750-LFC grid
determines the maximum downtilt and maximum uptilt for
flown arrays.
MG-MINA/LINA/750 Oriented for Maximum Array
Downtilt
When the MG-MINA/LINA/750-LFC grid is oriented with the
links toward the front of the flown loudspeakers, the grid
provides maximum downtilt for the flown array (when tilting
the grid). The label on the MG-MINA/LINA/750-LFC shows
this configuration as "Maximum Downtilt."
With the maximum downtilt orientation, the LINA at the top of
the array can be attached to the grid at 0° and –5° downtilt
(Figure 23).

Orientation, 0° and –5°
TIP:
The tilt for the MG-MINA/LINA/750 and the
array hung below it can be further tilted by using
chain motors, or differing lengths of steel or
SpanSets.
