M1D Rigging Grids and Accessories
MTG-1D TOP GRID IN FORWARD FLOWN CONFIGURATION
"Forward Flown" dilineates that the MTG-1D grid is oriented with its sliding extension frame to the rear. This is
the most common configuration for flying an M1D/M1D-Sub array. It provides from -14° to +14° of tilt in 2-degree
increments between the grid and the first loudspeaker when using an M1D as the first element of the array. If more
tilt is required, the grid may also be tilted up or down by using single or multiple rigging points. If further down tilt is
needed, this can be achieved using the grid's extension frame in the extended position.
Install the M1D grid cam as shown into the MTG-1D grid, with the grid side of the M1D grid cam facing the MTG-1D
grid. Secure all M1D grid cams with the quick release pins (QRPs), then install the M1D at the predetermined angle.
The M1D grid cam is only used in transition from the MTG-1D grid to the first M1D/M1D-Sub. After this is complete,
use the M1D links with the QRPs to complete the rest of the array as shown.
Maximum Load:
7:1 safety factor: Up to 16 M1Ds
or the equivalent weight of M1Ds
and/or M1D-Subs. (496 lbs, 225 kg)
5:1 safety factor: Up to 22 M1Ds
or the equivalent weight of M1Ds
and/or M1D-Subs. (682 lbs, 309.2
kg)
CAUTION:
the MTG-1D grid, it must always
be supported by at least one pick-up hole
from the main frame's center bracket. The
extension frame may be used as a secondary
pick-up location for tilting the array or
spreading the load between two points.
NOTE:
If the first element of the array
is an M1D-Sub, the M1D grid cam
needs to be reversed (grid side facing the
M1D-Sub). In this case, up tilt from 0° to +14°
in 2-degree increments is possible. Use M1D
links to complete the rest of the array.
