When choosing your rigging point capacities, always
keep in mind that the entire weight of the array may shift
completely to either the front or back points. Three factors
contribute to variations in the center of gravity:
1. The curvature of the array
2. The tilt of the entire array inclusive of the MTG-3D Top
Grid
3. The number and types of M3D elements and downfills
used
M3D PLACEMENT CALCULATOR
The M3D Placement Calculator, shown in Figure 4,
is a mechanical design tool for calculating structural
information about an M3D and/or M3D-Sub array. It is
implemented as an Excel spreadsheet and provides
information regarding rigging loads and array placement
and aiming. A customizable graphic representation of
the venue, as shown in Figure 4, can display up to three
balconies. The Meyer Sound M3D Placement Calculator is
approved by a certified structural engineering firm.
NOTE:
You need a computer loaded with
Microsoft Excel in order to run the M3D
