COMPONENT OVERVIEW
MG-1D Multipurpose Grid
The MG-1D multipurpose grid allows M1D ultra-compact
curvilinear array loudspeakers and M1D-Sub ultra-compact
subwoofers to be own or ground stacked. An adjustable
rear extension frame provides exibility and keeps the point
load equal. Up to 16 M1Ds (or the equivalent weight of M1D/
M1D-Subs) may be suspended from single or multiple rigging
points of appropriate rating, with a safety factor of 7:1. The
MG-1D also supports ying 7 M2Ds (or the equivalent weight
of M2D/M2D-Sub loudspeakers) at a safety factor of 7:1, and
provides a transition from the bottom of an M2D and/or
M2D-Sub array to:
 an M1D/M1D-Sub array
 1 UPA-1P compact wide coverage loudspeaker
 3 UPA-2P compact narrow coverage loudspeakers
 2 MSL-4 horn-loaded long-throw loudspeakers, or
 2 DS-4P horn-loaded mid-bass loudspeakers
MTG-1D Top Grid
The MTG-1D top grid provides multiple hanging
congurations for M1D and/or M1D-Sub arrays. MTG-
1D allows single- or multi-point support and bridles. An
adjustable rear extension frame provides exibility and keeps
the point load equal. Up to 16 M1Ds (or the equivalent weight
of M1D and M1D-Subs) may be suspended from single or
multiple rigging points of appropriate rating, with a safety
factor of 7:1.
MUB-1D Mounting U-Bracket
The MUB-1D mounting U-bracket supports multiple M1D
loudspeakers depending on the mounting conguration.
The MUB-1D is a simple yet versatile rigging option that can
provide numerous tilt angles, and is ideal for front ll, under
balcony, single unit or any small array applications.
NOTE: For large M1D arrays with or without
M1D-Subs it is recommended that you use
the MTG-1D top grid or MG-1D multipurpose grid.
