*The load rating includes the MG-MICA grid.

CAUTION: Do not exceed the maximum rated weight for the MGCP-MICA Center Point Rigging Beam

when it is used to pick up the MG-MICA grid. The ratings in Table 10 should be used instead of the

MG-MICA load ratings, which are rated for the grid’s own pick-up points.

CAUTION: Make sure that the single suspension point in the venue is rated for the load of the entire

suspended array, including the loudspeakers, grid, rigging beam, and other attached connections and

accessories.

Using the Center of Gravity feature in MAPP Online Pro makes very simple to determine the pick-up hole in the MGCP-

MICA when installed in the MG-MICA grid. Please follow the next steps using MAPP Online Pro:

1. Open the dialog Conﬁgure > Insert Loudspeaker System and create the array below the MG-MICA grid. Select

the MICA Forward or MICA Rearward grid position with MGCP, depending on whether more downtilt or more uptilt

is desired as a starting place. Insert the necessary quantity of loudspeakers up to the load rating on Table 10, set

the initial splay angles, and set the initial grid height and positioning.

2. Change splay angles, grid angle and height until the design meets the acoustical requirements.

3. If not active, go to View > Array COG (Center of Gravity) and place a check mark next to it. You will see a magenta

line that goes from the center of gravity of the array to the top of the sound ﬁeld.

4. Click the Zoom button along the top right of the Sound Field, and left-click and hold while drawing a box around

the top of the grid.

5. You will see the center of gravity line and the pick-up holes on the MGCP-MICA. Select the closest hole to the line.

Refer to Figure 8.1.

6. Rotate the grid until the CoG falls right into the center of the hole. This will give you the exact angle at which the

array will hang under those conditions.

7. Change grid angle and height until the design meets the acoustical requirements and the Center of Gravity falls

exactly on one of the pick-up holes.
