MUB-1D MULTIPURPOSE U-BRACKET IN FLOOR- OR CEILING-MOUNTED CONFIGURATION
In this conguration the MUB-1D U-bracket is used to mount and aim a single M1D on a oor, ceiling or other at
surface. It provides from +10° to -12° of tilt in 2-degree increments between the MUB-1D U-bracket’s mounting plane
and the M1D loudspeaker. For safety reasons, it is not recommended to use more than one M1D in a ceiling-mount
conguration.
First install the MUB-1D multipurpose U-bracket on the oor, ceiling or other at surface. Make sure to use mounting
hardware that has been rated to meet or exceed the weight being hung and is appropriate for the construction of the
mounting surface. Install the M1D loudspeaker into the MUB-1D U-bracket and secure the M1D with the quick release
pins (QRPs) at the predetermined angle (see page 20 for more information on setting tilt angles).
WARNING: Always use mounting
hardware that is appropriate for
the construction of the surface where
the MUB-1D U-bracket will be installed.
WARNING: Always use mount-
ing and rigging hardware that has
been rated to meet or exceed the weight
being hung.
MUB-1D MULTIPURPOSE U-BRACKET IN FLOWN CONFIGURATION
In own congurations, the MUB-1D U-bracket provides from +12° to -10° of tilt in 2-degree increments between the
MUB-1D and the rst M1D loudspeaker.
Install the MUB-1D as shown onto the rst M1D of the array and secure the M1D with the quick release pins at the
predetermined angle (see page 20 for more information on setting tilt angles). The MUB-1D U-bracket is only attached
directly to the rst M1D loudspeaker in the array. Use the M1D links with the QRPs to complete the rest of the array as
shown.
WARNING: When ying an array
from the MUB-1D U-bracket,
it must always be supported by the
pick-up holes whose load ratings meet
or exceed the weight of the array.
See page 21 for more information on
Maximum Load Ratings.
WARNING: Always use mounting
and rigging hardware that has
been rated to meet or exceed the weight
being hung.
