4. MUB-1D MULTIPURPOSE U-BRACKET
The MUB-1D multipurpose U-bracket is mainly designed to support and aim a single M1D ultra-compact curvilinear
array loudspeaker in a oor or ceiling mounted conguration. However, it is robust and versatile enough for ying small
arrays of M1D loudspeakers. Multiple mounting holes provide maximum exibility.
The MUB-1D U-bracket does not have the strength or functionality of a rigging grid and therefore it is NOT
recommended for the following applications:
- If the array’s length and the angles between the cabinets force its center of gravity to fall outside the footprint of
the MUB-1D.
- If the array includes M1D-Subs.
- If the array requires up or down tilt using chain motors.
- If the array exceeds the load rating of the MUB-1D.
For these and other own applications that require a rigging grid, the MTG-1D or the MG-1D should be used.
For ground stacked arrays that require a support grid, or when a transition from an M2D and M2D-Sub array to a M1D
array is needed, the MG-1D grid should be used.

ANGLE SETTING
A number of holes are provided on each end of the MUB-1D
multipurpose U-bracket to facilitate angle setting. The holes align with
those in the MRF-1D rigging frame on the M1D. Two quick release pins
— provided with the M1D loudspeakers — per side are used to mount
the M1D to the MUB-1D U-bracket.
A variety of tilt angles are available through the selection of pin positions.
The diagram below shows the angles that can be achieved with relation
to the MUB-1D’s mounting plane. In ceiling-mounted or own arrays,
positive angles are used for up tilt and negative angles are used for down
tilt. For oor mounted congurations, positive angles are used for down
tilt. The MUB-1D U-bracket provides from +10° to -12° of tilt in 2-degree
increments.
