Wall bracket mounting instructions
Follow these instructions to mount the SMS1990 loudspeaker using the supplied wall
mount bracket.
Warning: Installation should only be done by an experienced technician. Improper
installation may result in damage to the equipment, injury or death.
1. Mounting the wall bracket to the wall:
a. Mount the bracket so the slots in the ends are upwards as shown. This will support
the SMS1990 even if the clamp nuts become loose.
When mounted on a wall, the bracket
should be centered over a J-box that is
appropriately rated and installed for the
weight of the speaker and bracket. The
provided 6-32 screws should be inserted
through the holes labeled “A” as shown.
The holes labeled “B” should be used to
attach the bracket to a wall stud with user-
supplied hardware.
b. The wall bracket can also be mounted sideways on a vertical wall, or mounted on a
ceiling. Again, make sure that you consult a rigging professional to examine the wall
or ceiling and determine the proper hardware for mounting the bracket.
