MG-M’elodie multipurpose grid and Accessories 4. Using the MG-M’elodie MULTIPURPOSE GRID to Fly M’elodie Arrays ADJUSTING THE ANGLE BETWEEN THE GRID AND the FIRST M’ELODIE The MG-M’elodie has four captive grid links; each grid link has three positions. In flown configurations, the first M’elodie loudspeaker in the array can be connected to the MG-M’elodie grid at 0, -5, and -10 degrees depending on the combination of the grid links position (see Table 1).
MG-M’elodie multipurpose grid and Accessories ROTATING THE GRID TO ACHIEVE MORE DOWNTILT OR UPTILT The MG-M’elodie grid can be rotated to fly M’elodie loudspeakers in two positions with respect to the grid. The “rear flown” position (M’elodie is closer to the rear of the grid) is most useful for achieving a few degrees more of uptilt and it is labeled “Maximum Up-tilt” on the grid.
MG-M’elodie multipurpose grid and Accessories MG-M’elodie Pickup Configurations The MG-M’elodie grid can accommodate a variety of pickup configurations using its four side pickup points and/or the nine center pickup points. When possible, it is recommended to use front and rear pickup points to change the tilt of the grid and the array by using the front and rear motors. CAUTION: Always use properly rated rigging hardware. The use of 5/8" shackles for the MG-M’elodie grid’s pickup points is recommended.
MG-M’elodie multipurpose grid and Accessories In addition, the MG-M’elodie can be suspended from a single motor. However, limitations like the load rating of the motor and the pickup point in the ceiling “above the hook” need to be taken into consideration. Also, it becomes more difficult to change the tilt angle of the grid. NOTE: The design of the MG-M’elodie allows the use of any pickup configuration without affecting the load rating.
MG-M’elodie multipurpose grid and Accessories MAPP ONLINE PRO MAPP Online Pro is a powerful acoustical prediction software that is an invaluable tool when designing a system.
