    x 1 INTRODUCTION The M3D and M3D-Sub QuickFly rigging system is a complete integrated solution for transporting and ying M3D and M3D-Sub loudspeakers. This system includes everything below the motors, to the caster rails and covers that carry and protect the system in transport. All the hardwar e for rigging the system remains captive to the lou ...

    2 3 Using a three- or four -high M3D block will make each block heavier (see T able 1) and less stable, so the blocks will requir e extra care when rolling over an uneven surface and up truck ramps. Conversely , larger blocks will make more efcient use of a truck’ s car go space and make a more efcient load-in and strike. The optional M3D t ...

  • Meyer Sound M3D-SUB - page 11

    2 3 TIP: Meyer Sound’ s optional transit covers will protect M3Ds stacked for transport. They are easy to use, because one side opens with V elcro seams, allowing two stagehands to easily put on the cover without having to lift it over the top of the block. W e suggest you strap each block, once loaded, with a car go strap to prevent rubbing thr ...

    4 5 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. Thr ee 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 T op Grid 3. The number and types of ...

If scaled sectional drawings of the venue are not available, you can measure the venue by using a l ...

    6 7 Once you enter measurements into the M3D Placement Calculator , it will help you visualize the approximate vertical splay angles needed. The calculator will also help with other rigging considerations. Save the results of these calculations for use when you assemble the M3D array as described in the section “Array Assembly and Angle Adjustmen ...

  • Meyer Sound M3D-SUB - page 15

    6 7 LIFTING MECHANISMS The number and lift capacity of chain motors used to lift the array are dependent on the array’ s combined weight, including the weight of any underhung clusters, and its orientation and splay . For a smaller array , it may be sufcient to use 1-ton motors, but for lar ger arrays, 2-ton motors may be necessary . The lift ...

    8 9 NOTE: When using chains or making custom bridle lengths to achieve vertical tilt, be sure the center of gravity of the nal hung array is within the allowable limits of the MTG-3D T op Grid. (See “M3D Placement Calculator .”). TIP: Some venues, such as theaters, have only side-to-side motor points available through the ceiling plaster . I ...

    8 9 TIP: If the bottom of the array ends up being too far downstage during assembly , have stagehands breast it upstage until assembly is complete and it is own to its nal trim position. 5. It is often necessary to increase the stability of an array in venues with very high structural steel from which the array is suspended. The rigging point ...
