    Long-term safe operation is a central concern in the design and manufacture of any rigging/flying system. Meyer Sound has taken great care in material selection and component design. In all critical cases, load points are redundant, with a safety margin that allows one or more load points to fail while maintaining system integrity.

    TIP: Meyer Sound’s optional transit covers will protect M3Ds stacked for transport. They are easy to use, because one side opens with Velcro seams, allowing two stagehands to easily put on the cover without having to lift it over the top of the block.

    To facilitate accurate coverage predictions, however, the calculator provides detailed positional data that can be entered into Meyer Sound’s MAPP Online™ acoustical prediction program. In combination, these two Meyer Sound tools give you the ability to predict sound coverage and to calculate the physical placement of arrays to accomplish the prediction.

    The allowable system center of gravity range must be 1. Once the motors are attached to the MTG-3D Top within the front rigging point and one of the pickup Grid, raise the MTG-3D Top Grid, as shown in Figure choices provided, as illustrated in Figure 34 on page 26. 13, to the necessary working height in preparation for attaching the first block of M3Ds.

    ADJUSTING ANGLES By using both MAPP Online and the M3D Placement Calculator, you should now have determined the required tilt for the MTG-3D Top Grid and splay angles between elements for your array. The M3D Placement Calculator (see “M3D Placement Calculator”) also provides a warning indication if the center of gravity falls too close to, or outside of, the front or back point that was chosen in the array’s final...
