RIGGING
KF740 Series arrays can be suspended or ground-stacked. When suspended, the KF740 can be
used in conjunction with the KF730, KF737, KF760, and KF761 with the use of adapter bars.
This chapter details how to physically configure KF740 Series arrays. The following are the
recommended methods for most situations. Specific situations may require other methods. It is
the user's responsibility to determine the viability and safety for alternate methods and implement
them accordingly.
KF740P: The procedures to suspend and ground-stack permanently installed KF740Ps and are
detailed in instructions provided with the KF740P instillation hardware kits. Use those instructions
for rigging any KF740P products and their accessories.
NOTE: The 'P' version of the KF740 will not mate to 'P' versions of any other product.

RIGGING WARNINGS
WARNING: Suspending anything, especially overhead of people, should be done with extreme
caution. Always engage the services of a certified professional who is qualified to determine the
requirements for and to implement overhead rigging. Only persons with the knowledge of proper
hardware and safe rigging techniques should attempt to suspend KF740 Series arrays overhead.
Failure to follow these precautions may result in damage to the equipment, injury, or death.
DANGER: When suspending or stacking KF740 loudspeakers, avoid placing any parts of the
body between enclosures, enclosures and Fly-bar, and enclosures and Adaptor-bars. Always use
the integral handles to lift or position enclosures. Failure to follow this precaution may result in
damage to the equipment, injury, or death.
CAUTION: A KF740 weighs approximately 107 lb / 49 kg. Always use two people or mechanical
assistance to lift a KF740.
IMPORTANT RIGGING NOTE: Each Quick Release Pin, used to attach enclosures together, can
be inserted into one of several holes in both the Hinges and Hinge Tubes integral to the
enclosures. The particular holes used set the splay angle between the enclosures and thus their
aiming. Use the correct holes as determined by Resolution software or as desired by the user.
IMPORTANT TRANSPORTATION NOTE: To avoid damage to the Quick Release Pin handles
when transporting, always insert the pins from the inside of the Hinge Tubes. This keeps the
Quick Release Pin handles from extending beyond the footprint of the enclosures or Fly-Bar.
6.2
SUSPENSION LOAD RATING - WORKING LOAD LIMIT (WLL)
The Fly-Bar has a WLL for suspending a maximum under-hang of sixteen (16) KF740
loudspeakers. The design factor for this rating is 10:1.
CAUTION: Different combinations of loudspeakers allowing for a variety of splay angles between
units combined with multiple possible Fly-bar hang positions creates unique loading of stresses
on structural members in any given array. Some array configurations may not allow for a 10:1
design factor for sixteen (16) units. Consult Resolution for specific WLL information for any given
array configuration. Always consult Resolution for WLL information when combining the KF740
with KF730 or KF737 and KF760 or KF761 loudspeakers.

FLY-BAR RIGGING RECOMMENDATIONS
WARNING: It is the responsibility of the user to ensure the attachment to the Fly-Bar, the rigging
method, and attachment to structure are determined by a certified professional who is qualified to
