USING THE MG-1D GRID TO FLY M2D AND M2D-SUB LOUDSPEAKERS
For smaller M2D arrays, the MG-1D multipurpose grid can be used as the primary rigging frame. If greater exibility
with up or down tilt of the entire array is required, the MG-2D multipurpose grid should be used.
Install the M2D CamLink (A) as shown between the MG-1D multipurpose grid (C) and the rst cabinet. Install the M2D
FrontLinks (B) as shown, and secure all with three QRPs. Note that MG-1D grid is ipped 180 degrees from its normal
position (leveling feet extenders are pointing downward).
NOTE: For large M2D arrays with or without M2D-Subs, use the MG-2D multipurpose grid.
CAUTION: The leveling feet must always be detached from the MG-1D multipurpose grid before ying
a system. Unscrew the entire assembly, including the threaded leg, and remove completely.
CAUTION: When
ying an array from
the MG-1D multipurpose
grid, it must always be
supported only by the
pick-up holes from the main
frame’s center bracket.
CAUTION: Never use the MG-1D
multipurpose grid for ground-stacking
M2D or M2D-Subs.
Maximum Load:
7:1 safety factor: Up to 7 M2Ds or
the equivalent weight of M2Ds and/
or M2D-Subs or other products
specied for use with this grid.
5:1 safety factor: Up to 10 M2Ds
or the equivalent weight of M2Ds
and/or M2D-Subs or other products
specied for use with this grid.
CAUTION: Do not use the MG-1D
extension frame with M2D and/or
M2D-Sub cabinets. The MG-1D extension
frame is rated only for use with M1D and
M1D-Sub loudspeakers.
