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 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...

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. Three factors contribute to variations in the center of gravity: 1. The curvature of the array 2. The tilt of the entire array inclusive o...
