CHAPTER 4: MOUNTING THE MM-4XP
IMPORTANT SAFETY CONSIDERATIONS
When installing Meyer Sound loudspeakers, the following
precautions should always be observed:
■ All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reli-
ability of any rigging method for their application. Rigging
should only be carried out by experienced professionals.
■ Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
■ Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
■ Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
■ Make sure bolts and eyebolts are tightened securely.
Meyer Sound recommends using Loctite
®
on eyebolt
threads and safety cables.
■ Inspect mounting and rigging hardware regularly. Imme-
diately replace any worn or damaged components.
MOUNTING THE MM-4XP WITH THE
MUB-MM4XP U-BRACKET
The MUB-MM4XP U-bracket allows the MM-4XP to be
mounted on virtually any flat surface at adjustable angles.
To mount the MM-4XP with the MUB-MM4XP U-bracket:
1. Mount the MUB-MM4XP U-bracket to the mounting sur-
face using screws in the two holes in the back of the
U-bracket. Use fastening hardware appropriate for the
mounting surface.
2. Insert the MM-4XP into the U-bracket, seating its sides
against the bracket’s attached neoprene strips. Align the
loudspeaker’s screw inserts near the top of the
U-bracket’s slots to allow for maximum tilting.
3. Secure the loudspeaker to the U-bracket using the two
3/8-16 screws and two shoulder washers included with
the MUB-MM4XP. The shoulder washers should be
placed between the screws and the outside of the
U-bracket, with the shoulder oriented toward the loud-
speaker. Do not yet tighten the U-bracket screws.
CAUTION: Make sure to use the shoulder
washers. They insulate the MM-4XP from the
U-bracket and mounting surface, eliminating ground-
ing and differential problems.
4. Adjust the angle of the loudspeaker as desired.
5. Tighten the U-bracket screws to secure the MM-4XP.
