2. MG-1D MULTIPURPOSE GRID
The MG-1D multipurpose grid allows multiple M1D ultra-compact curvilinear array loudspeakers, M1D-Sub ultra-
compact subwoofers, M2D compact curvilinear array and M2D-Sub compact subwoofers to be own, and provides
ground support for M1D and M1D-Sub loudspeakers. The MG-1D grid can also serve as a transition grid. Refer to the
overview on page 5 for possible congurations. There are pick-up points in the center of the grid, and three pick-up
points on the extension frame.

MG-1D Multipurpose Grid Dimensions
NOTE: To expand or
retract the MG-1D grid
extension frame, remove all four
QRPs. Once the extension frame
is extended to its outer position,
reinstall the QRPs, securing the
extension frame safely to the
MG-1D grid. If you are working
in conditions where weight is a
factor, you have the option to
reduce your overall load by 20
pounds (9.01 kg) by removing the
extension frame completely.
