Using a three- or four-high M3D block will make each The optional M3D transit covers, shown in Figure 2, are block heavier (see Table 1) and less stable, so the blocks constructed of wear-resistant nylon fabric with Velcro will require extra care when rolling over an uneven surface closures to protect the M3D and loudspeakers from scuffs and up truck ramps. Conversely, larger blocks will make and weather during transport. more efficient use of a truck’s cargo space and make a more efficient

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. We suggest you strap each block, once loaded, with a cargo strap to prevent rubbing through the covers and damaging the M3D cabinets or adjacent equipment. M3D Transport As a reference, a three-high M3D block weighs approximately 1245 pound

LIFTING MECHANISMS USE FRONT AND BACK MOTORS WHENEVER POSSIBLE The number and lift capacity of chain motors used to lift Front-to-back bridle point configurations, illustrated in the array are dependent on the array’s combined weight, Figure 7 and configurations A, E, and F in “Appendix A including the weight of any underhung clusters, and — Configurations and Load Ratings,” allow the use of its orientation and splay.

STACKING AN M3D ARRAY ATTACHING MOTORS TO THE MTG-3D TOP GRID Use rated steel cables and shackles when attaching motors to the MTG-3D Top Grid, as shown in Figure 12. The MTG-3D Top Grid will accommodate 5/8-inch and 3/4-inch shackle sizes on its pickup points. Figure 10. Checking phase (chain direction) 4.

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 configuration.
