CONFIGURATION G

In conguration G, the steel cables are connected to a

single lift point from the four rigging points on the MTG-3D

Top Grid.

The array is lifted from a single point attached to each of the

MTG-3D Top Grid corner lifting points as shown in Figure

40. An array of up to 16 M3Ds can be supported.

The four-way bridle may be attached to each corner

of the MTG-3D Top Grid with four 5/8-inch or four 3/4-

inch shackles. The combined weight of the maximum

combination of M3Ds and M3D-Subs or other

loudspeakers, such as MSL-4s and CQs, which can be

under-hung in this conguration, cannot exceed the total

equivalent weight of the allowable number of M3Ds as

shown in Table 13.

NOTE: The lift mechanism must be rated to

support the total weight of the entire array.

The array must have suitable tie-downs to eliminate sway

and twist.

CAUTION: DO NOT use the MTG-3D Top

Grid in the extended position when an array

is hung from a single point as shown in

Figure 40.
