MG-3D/M multipurpose grid and Accessories 1. General Information Safety Statement Please read this Statement carefully and in its entirety. It contains important information regarding safety issues, including guidelines for general safe use of rigging systems as well as advisories on government regulations and liability laws. SCOPE OF THIS MANUAL Although this manual contains much useful information on rigging in general, it does not claim to be a comprehensive resource on the subject.
MG-3D/M multipurpose grid and Accessories Safety Responsibilities “Above the Hook” In most touring applications of rigging systems, the touring sound provider is normally responsible for ensuring the safety of the suspension system only below the attachment point. The safety and suitability of the attachment point is generally seen as the responsibility of the venue owner or operator. However, this distinction (“above the hook” versus “below the hook”) can be open to interpretation.

MG-3D/M multipurpose grid and Accessories MLK-MILO Link Kit The MLK-MILO link kit is required to attach a MILO loudspeaker to the MG-3D/M multipurpose grid. In flown configurations, the first MILO loudspeaker in the array is always connected to the MG-3D/M grid at 0°. In ground-supported configurations, the first MILO loudspeaker in the array can have from –1° to 4° in relation to the MG-3D/M grid.
MG-3D/M multipurpose grid and Accessories MG-3D/M Grid and MILO Rear Flown configuration The MG-3D/M multipurpose grid allows you to fly MILO loudspeakers in two positions in relation to the MG-3D/M grid. The “rear flown” position is achieved by rigging MILO loudspeakers using the holes for the AlignaLinks that are closer to the rear of the MG-3D/M grid. This position is most useful for achieving superior up tilt in the MG-3D/M grid and, subsequently, the array.
MG-3D/M multipurpose grid and Accessories MG-3D/M Grid and MILO Front Flown configuration The MG-3D/M multipurpose grid allows you to fly MILO loudspeakers in two positions in relation to the grid. The "front flown" position is achieved by rigging MILO loudspeakers using the holes for the AlignaLinks that are closer to the front of the grid. This position is most useful for achieving superior down tilt in the MG-3D/M grid and, subsequently, the array.
MG-3D/M multipurpose grid and Accessories MILO Ground-supported Configurations By simply flipping the MG-3D/M multipurpose grid over from its flown configuration and installing the levelling feet, the MG-3D/M grid can be used to provide ground support for a MILO array. The MG-3D/M grid provides two positions — front and rear. Either position may be used to stack MILO loudspeakers, although the front position is most useful for stacking a predominantly up tilted MILO array.

MG-3D/M multipurpose grid and Accessories MLK-3D Link Kit The MLK-3D link kit is required to attach an M3D/M3D-Sub to the MG-3D/M multipurpose grid. In flown configurations, the first M3D/M3D-Sub cabinet in the array is always connected to the MG-3D/M grid at 0°. In ground-supported configurations, the first M3D/M3D-Sub cabinet in the array can have from 0° to 5° with respect to the MG-3D/M grid.
MG-3D/M multipurpose grid and Accessories MG-3D/M Grid and M3D/M3D-sub Rear Flown configuration The MG-3D/M multipurpose grid allows you to fly M3D/M3D-Sub loudspeakers in two positions with respect to the grid. The “rear flown” position is achieved by rigging M3D/M3D-Sub loudspeakers using the holes for the captive links that are closer to the rear of the MG-3D/M. The rear flown position is highly useful for achieving superior up tilt in the MG-3D/M grid and, subsequently, the array.
MG-3D/M multipurpose grid and Accessories MG-3D/M Grid and M3D/M3D-Sub Front Flown configuration The MG-3D/M multipurpose grid allows you to fly M3D/M3D-Sub loudspeakers in two positions in relation to the MG-3D/M grid. The “front flown” position is achieved by rigging M3D loudspeakers using the holes for the MTL-3D transition links that are closer to the front of the MG-3D/M grid. This position is useful for achieving optimum down tilt of the MG-3D/M grid and, subsequently, the array.
MG-3D/M multipurpose grid and Accessories M3D/M3D-Sub Ground-supported Configurations By simply flipping the MG-3D/M multipurpose grid over from its flown configuration, it can be used to provide ground support for an M3D/M3D-Sub array. The MG-3D/M grid provides two positions — front and rear. Either position may be used to stack M3D loudspeakers, although the front position is most useful for stacking a predominantly up tilted M3D array.
MG-3D/M multipurpose grid and Accessories 4: Transitions and Accessories When used with other Meyer Sound transition kits, the MG-3D/M multipurpose grid can support a variety of flown and ground-supported configurations using MILO, M3D/M3D-Sub, and other M Series loudspeakers. MTR-3D/M Transition Rail Kit: M3D/M3D-Sub to MILO Meyer Sound’s MTR-3D/M transition rail kit allows you to easily transition from an M3D/M3D-Sub to a MILO loudspeaker or from a MILO to M3D/M3D-Sub.
MG-3D/M multipurpose grid and Accessories The MTR-3D/M transition rail kit can be reversed and used in flown or ground-supported configurations where an M3D/M3D-Sub is underneath a MILO loudspeaker. In this configuration the MATB-3D adjustable transition bar allows the transition rails to be tilted at 0°, 6° to 12° with respect to the M3D/M3D-Sub(s) below.
MG-3D/M multipurpose grid and Accessories MTB-2D/M Transition Bar Kit: MILO to M2D The combination of the MTB-2D/M transition bar kit and MG-2D multipurpose grid allows you to easily transition from MILO to M2D loudspeakers. MTB-2D/M transition bars provide the link needed to attach an MG-2D grid below a MILO loudspeaker; a downfill array of M2Ds can then be flown from the MG-2D as required using the full capabilities and flexibility of the MG-2D grid.
MG-3D/M multipurpose grid and Accessories MTK-2D Transition kit: M3D/M3D-Sub to M2D Using Meyer Sound’s MTK-2D transition kit, the MG-2D multipurpose grid can be attached underneath an M3D/M3DSub cabinet. A downfill array of M2D loudspeakers can then be flown from the MG-2D grid as required using the full capabilities and flexibility of the MG-2D grid. The MTK-2D kit contains the links and pins necessary for the transition between an M3D/M3D-Sub loudspeaker and the MG-2D grid.
MG-3D/M multipurpose grid and Accessories PBF-MILO Pull-Back Frame The up and down tilt of the MG-3D/M multipurpose grid and the complete MILO array hung underneath can be adjusted using chain motors, or differing lengths of steel cables or chain lengths. The rigging connections between MILO loudspeakers using the MFAL-MILO front AlignaLinks and MRAL-MILO rear AlignaLinks are rigid, and in most applications array tilt can be achieved by adjusting the angle of the MG-3D/M grid.
MG-3D/M multipurpose grid and Accessories MVE-MILO Vertical Extension Bars In a MILO array, MFAL-MILO front and MRAL-MILO rear AlignaLinks at the cabinet corners couple the units for either flying or stacking, and allow nine positions from 0° to 5° of cabinet splay (0°, .5°, 1°, 1.5°, 2°, 2.5°, 3°, 4°, 5°). For applications where the desired splay angle is greater than the full 5° capability of the MRAL-MILO rear AlignaLinks, the MVE-MILO vertical extension bars can help.
MG-3D/M multipurpose grid and Accessories MCF-MILO Caster Frame Kit The MCF-MILO caster frame allows you to transport stacks of up to four entire MILO loudspeakers high. Whether you’re deploying and striking a MILO array, the MCF-MILO frame can also support the weight of the array — making the array easy to assemble or dissemble by using blocks of up to four MILO loudspeakers. You may use any of first three the top holes in the MRAL-MILO real AlignaLink to attach the MCF-MILO.
