CHAPTER 5: QUICKFLY RIGGING
500-HP subwoofers equipped with the optional MRF-500
rigging frame can be linked directly to the MG-M’elodie
multipurpose grid, M’elodie loudspeakers, as well as addi-
tional 500-HPs to form flown and groundstacked arrays. In
addition, all 500-HPs have a 1.5-inch pole-mount receptacle
for mounting UltraSeries loudspeakers that include support
for pole-mount adapters.
When using subwoofers to enhance low-frequency head-
room in full-range and mid-high sound systems, their effec-
tiveness is determined by how the subwoofers are grouped,
how they are placed in relation to the other loudspeakers in
the system, and how they are oriented to nearby walls and
floors.
Important Safety Considerations!
When installing Meyer Sound loudspeakers and subwoof-
ers, 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.
THE MRF-500 RIGGING FRAME WITH
GUIDEALINKS
500-HPs equipped with the MRF-500 rigging frame include
three GuideALinks on each side of the subwoofer. The
GuideALinks, located at the bottom of the frame in the front,
middle, and rear, attach to GuideALink slots in loudspeakers
(500-HPs or M’elodies) flown below the unit.
The rigging frame also includes three GuideALink slots at
the top of the frame (in the front, middle, and rear) for
attaching to GuideALinks — from the MG-M’elodie multipur-
pose grid or from another 500-HP — when the subwoofer is
flown. The slots are also used when attaching to the
GuideALinks of 500-HPs and M’elodies groundstacked
above the unit.
