CHAPTER 4: RIGGING
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 mounting and rigging method for their
application. Mounting and 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.
MYA-DES CRADLE-STYLE YOKE
The Acheron Designer includes M6 threaded attachment
points on the cabinet bottom for the optional MYA-DES cra-
dle-style yoke, allowing the unit to be suspended from a sin-
gle hanging point.
The yoke’s cradle can be pivoted to install the loudspeaker
with downtilt or uptilt. A “C” or “G” hanging clamp and steel
safety cable (not included) are required to suspend the yoke.
CAUTION: The MYA-DES mounting yoke is
rated for a maximum downtilt of 45 degrees.
NOTE: The top bar of the MYA-DES yoke
accommodates hanging clamps with standard
1/2- inch or 12 mm bolts.
NOTE: For Acheron Designer dimensions and
weight with the MYA-DES yoke, refer to
Appendix A, “Acheron Designer Specifications.”
