Safety
The ETX Powered Loudspeaker systems and rigging accessories in this manual have a
minimum structural safety factor of 8:1 when used as intended. The safety factor is defined as
the ratio of the ultimate-break strength divided by the working-load limit. The ultimate-break
strength represents the force at which a part will structurally fail. The working-load limit is the
maximum load that the user shall apply. The safety factor provides a margin of safety above
the working-load limit to accommodate normal dynamic loading and normal wear.
When ETX Powered Loudspeaker systems are suspended using the ETX Powered Loudspeaker
rigging accessories as illustrated in this manual, the resulting forces loads will be within the
working-load limits of both the loudspeaker systems and the rigging accessories, and a safety
factor of at least 8:1 will be maintained. The use of rigging configurations other than
recommended by Electro-Voice in this manual for either the ETX Powered Loudspeaker or ETX
Powered Loudspeaker rigging accessories are at the risk of the user.
Warning!
Suspending any object is potentially dangerous and should only be attempted by individuals
who have a thorough knowledge of the techniques and regulations of suspending objects
overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into
account all current national, federal, state, and local laws and regulations. It is the
responsibility of the installer to ensure all loudspeakers are safely installed in accordance
with all such requirements. When loudspeakers are suspended, Electro-Voice strongly
recommends the system be inspected at least once per year or as laws and regulations
require. If any sign of weakness or damage is detected, remedial action should be taken
immediately. The user is responsible for making sure the wall, ceiling, or structure is capable
of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker
not associated with Electro-Voice is the responsibility of others.
Prior to use, inspect the suspension points and associated hardware for any cracks,
deformations, broken welds, corrosion, missing or damaged components which could reduce
the suspension points strength. Replace any damaged hardware. Never exceed the limitations
or maximum recommended load intended for the suspension points. As an added safety
measure, it is suggested the user install an extra suspension point back to the building
structural supports. This redundant safety point should have as little slack as possible (less
than one (1) inch is preferable). Prior to each use, inspect the loudspeaker enclosures for any
cracks, deformations, missing or damaged components, which could reduce enclosure
strength. Replace any loudspeaker systems damaged or missing hardware.
Warning!
Eyebolts must be fully seated and oriented in the plane of pull. Always use fender washers at
least 1.5 inch in diameter and 1/16 inch thick under the eyebolt to distribute the load on the
enclosure.
REFERENCE: For more information, see ETX Powered Loudspeakers User Manual
(F.01U.276.083).

Mounting U-Bracket to the wall
The wall mount U-Bracket is used to mount a loudspeaker to the wall.
Caution!
Due to the weight of the Electro-Voice loudspeaker system, it is imperative the bracket is
properly secured to the wall. The choice of fastener (not supplied) will be determined by the
material and construction of the mounting surface. The user is responsible to ensure the
mounting surface and fasteners are capable of supporting the weight of the loudspeaker.
Caution!
Two (2) person lift and placement is recommended for the heavier loudspeakers. Single
person lift and placement of heavier loudspeakers could cause injury.
Notice!
The wall U-Bracket mounting holes accept M10 or 3/8-inch fasteners. The horizontal holes are
located 16-inches apart for attachment to studs.
