INCLUDING M3D-SUBS IN AN ARRAY
M3D-Subs can be included in an array in the same
manner as M3Ds.
Refer to the M3D Operating Instructions for details on
the use of M3D-Subs in an array and suggestions for the
optimum conguration with M3D loudspeakers to achieve
the desired coverage and sound pressure level (SPL) for
a venue while maintaining maximum headroom for all
elements of the array.
The M3D-Subs may be stacked up to four high for
transport and use. They usually don’t need to be
restacked in the truck or in the venue, so they require
fewer stagehands. The cable harnesses can be built for
modules of three or six, resulting in a very efcient setup
and strike.
STRIKING THE ARRAY
Taking down an M3D system is basically the reverse of the
installation process.
1. Attach the caster rails to the lowest cabinet as
the array is being lowered and when the bottom
loudspeaker is at about waist height.
2. Level the bottom cabinet to keep it as parallel as
possible to the oor.
3. While applying some pull on the QRPs holding the
CamLinks that you want to restore to 0˚, lower the
array onto the caster rails.
4. Stop the motors once both QRPs are pulled out from
the array.
5. Slowly bump the motors down until you can reinsert
the QRPs into the 0˚ hole.
6. Repeat this process until the rst block is fully restored
to 0˚.
7. Break the block away from the array by pulling all four
QRPs, and then bumping the array up to allow the
lowest block of cabinets to be wheeled away.
8. Repeat this process until all blocks are removed from
the array and the MTG-3D Top Grid is removed from
the rigging shackles.
TIP: When touring or using the same array
multiple times, you can leave the set vertical
splay angles in the blocks of cabinets while
in transport for speedier strike and setup as
shown in Figure 33. This also minimizes the
adjustments made between cabinets when
touring.

TIP: Note that the MTG-3D Top Grid is
attached to the block at the right in Figure
33. This provides a convenient method of
transport, and the top block in the array is
ready for assembly at the next venue.
