Working load limits and design factors
A list of the suspension components and the respective working load limit data at various design factors is
available on request. The tabulated design factors are for static loads only. The choice of which design factor
to use will depend upon the jurisdiction and venue of installation, as well as the conditions of suspension.
Dynamic conditions are determined by unknown, installation-specific factors and should be referred to a
licensed structural engineer for clarification before proceeding with any suspension of the equipment. The
data presented is based upon the listed component weights.
Many users of line array systems have found that suspending the subwoofers with the array provides audible
benefit. Additionally, many venues lack physical space for floor-mounted subs. For these reasons, the
subwoofer includes suspension hardware and, with selection of the appropriate suspension accessories,
subwoofers may be flown at the top of an array.
Suspended installation
DANGER!
This speaker system must only be suspended by experienced and trained persons - Danger to
Life due to crashing speaker systems!
Trained persons are e.g. Head Rigger, Lightcrew head etc.
If you lack these qualifications, do not attempt the installation yourself, but instead use a professional
structural rigger.
If you have doubts concerning the safety of a possible installation, do NOT install the speaker system!
The line array system has to be installed out of the reach of people.
The installation material must always hold at least 12 times the weight of the speaker systems.
Attach the flying bracket to the suspension structure using a 5/8” (16 mm) screw pin anchor shackle and
appropriate sling, cable, etc. Lower the flying bracket onto the subwoofer and align the appropriate holes in
the suspension links and flying bracket, fully insert the safety pins, and ensure all pins lock properly. Before
lifting, ensure the audio connection to the enclosures are correct and functioning.
