FLYING A COMPLETED ARRAY
Figure 31 shows an example of rigging points chalked on
the ground, a fully rigged block of three M3D loudspeakers
with an MTG-3D Top Grid mounted, positioned, and ready
to y.
Use the following procedure to y rigged blocks and
arrays into their nal position.
Figure 31. Fully rigged M3D block ready to y
1. If the array has front-to-back rigging hoists
(conguration type A, E, or F as described in
“Appendix A — Congurations and Load Ratings”),
raise the rear motors until they are bearing weight
along with the front motors.
2. Raise the array to its nal trim height.
3. If the array has front-to-back rigging, adjust the array’s
vertical tilt to the desired angle using the front and rear
motors as required.
4. If the array has side-to-side rigging, (conguration
type B, C, or D as described in “Appendix A
— Congurations and Load Ratings”) check that
the array angle set in the procedure described in
“Adjusting Angles” is correct in the own array and
make any nal adjustments as needed.
5. After the M3D array has been own into its nal
vertical position, check the horizontal angle of the
array. If the array is not parallel to the stage or the
array is not aimed in the desired direction, use rigging
ropes tied to the lower sides of the array to rotate the
array into its nal, correct position.
TIP: You can quickly check the vertical
orientation by looking through the horizontal
spaces between the cabinets. It is usually
easy to see light through these spaces in
an outdoor venue. Often the cabinets are in
a darker area than the daylight and, using
this method, it is possible to match the two
sides and see where they are focused. It
is also possible to check other locations in
the venue, such as the front-of-house mixer
area. Binoculars, item 1 in Figure 5, are also
a helpful tool for seeing these gaps from a
distance..
Cable tie-down rings at the rear of the M3D cabinet are
provided as shown in Figure 32.

Cable connectors are protected from wet weather by the
rain hood as shown in Figure 32.
CAUTION: Do not use the cable tie-down
rings at the rear of the M3D for pullback or
position adjustment of the array.
