3. Heed all warnings.
4. Follow all instructions.
5. Do not expose the product to direct rain or sea spray.
6. Clean only with a dry cloth.
7. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce
heat.
8. Only use attachments / accessories specied by the manufacturer.
9. Use only with a cart, stand, tripod, bracket, or table specied by the manufacturer or sold with the

avoid injury from tip-over.
10. Refer all servicing to qualied service personnel. Servicing is required when the apparatus has been damaged
in any way, such as liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped.
11. Contact JBL Professional for advanced servicing issues.
12. CAUTION – DO NOT PERFORM ANY SERVICING UNLESS YOU ARE QUALIFIED TO DO SO.
13. Prolonged exposure to excessive SPL can cause hearing damage: the loudspeaker is easily capable of
generating sound pressure levels (SPL) sucient to cause permanent hearing damage to performers, production
crew and audience members. Caution should be taken to avoid prolonged exposure to SPL in excess of 90 dB.
14. Read the System Rigging Manual before installation and use of the product.
15. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
16. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not t into your outlet, consult an
electrician for replacement of the obsolete outlet.
17. Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
18. Unplug this apparatus during lightning storms or when unused for long periods of time.
19. To completely disconnect this apparatus from the AC mains, disconnect the power supply cord plug from the
AC receptacle.
20. “WARNING – TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUS
TO RAIN OR MOISTURE.”
21. Do not expose this equipment to dripping or splashing and ensure that no objects lled with liquids such as
vases, are placed on the equipment.
22. The main plug of the power supply cord shall remain readily operable.

SAFETY INFORMATION
GENERAL HARDWARE INFORMATION
Any hardware used in an overhead suspension application must be load rated for the intended use. Generally,
this type of hardware is available from rigging supply houses, industrial supply catalogs and specialized rigging
distributors. Local hardware stores do not usually stock these products. Hardware that is intended for overhead
suspension will comply with ASME B30.20 and will be manufactured under product traceability controls. Compliant
hardware will be referenced with a working load limit (WLL) and a traceability code.
IMPORTANT SAFETY WARNING
The information in this section has been assembled from recognized engineering data and is intended for
informational purposes only. None of the information in this section should be used without rst obtaining competent
advice with respect to applicability to a given circumstance. None of the information presented herein is intended as
a representation or warranty on the part of JBL. Anyone making use of this information assumes all liability arising
from such use.
All information presented herein is based upon materials and practices common to North America and may not
directly apply to other countries because of diering material dimensions, specications and/or local regulations.
Users in other countries should consult with appropriate engineering and regulatory authorities for specic
guidelines.
Correct use of all included hardware is required for secure system suspension. Careful calculations should always
be performed to ensure that all components are used within their working load limits before the array is suspended.
Never exceed the maximum recommended load ratings.
THIS APPARATUS CONTAINS POTENTIALLY LETHAL VOLTAGES. TO PREVENT ELECTRIC SHOCK OR
HAZARD, DO NOT REMOVE CHASSIS, INPUT MODULE OR AC INPUT COVERS. NO USER SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
The lighting ash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of uninsulated “Dangerous Voltage” within the product’s enclosure that may be of
sucient magnitude to constitute risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user to the presence
of important operating and maintenance (servicing) information in the literature accompanying the
product.

INSPECTION & MAINTENANCE
INSPECTION & MAINTENANCE
Before suspending any speaker system always inspect all components (enclosure, rigging frames, pins, eyebolts,
track ttings, etc.) for cracks, deformations, corrosion or missing/loose/damaged parts that could reduce strength
and safety of the array. Do not suspend the speaker until the proper corrective action has been taken. Use only
load-rated hardware when suspending JBL suspendable loudspeaker models.
Suspension systems are comprised of mechanical devices and, as such, they require regular inspection and routine
maintenance to ensure proper functionality. Before suspending or pole mounting any speaker system, always
inspect all components (enclosure, suspension frames or brackets, pins, eyebolts, etc.) for cracks, deformations,
corrosion or missing/loose/damaged parts that could reduce strength and safety of the array.
Do not suspend or pole mount the speaker until the proper corrective action has been taken.
Installed systems should be inspected at least annually. The inspection shall include a visual survey of all corners and
load-bearing surfaces for signs of cracking, water damage, delamination or any other condition that may decrease
the strength of the loudspeaker enclosure.
Accessory suspension hardware provided with or for BRX systems must be inspected for fatigue at least annually
or as required by local ordinance. The inspection shall include a visual survey of the material for signs of corrosion,
bending or any other condition that may decrease the strength of the fastener. Additionally, any eyebolts shall be
checked for possible spin-out of the enclosure.
For all other hardware and ttings, refer to the hardware manufacturer’s inspection and maintenance guidelines for
process.
JBL is not responsible for the application of its products for any purpose or the misuse of this information for any
purpose. Furthermore, JBL is not responsible for the abuse of its products caused by avoiding compliance with
inspection and maintenance procedures or any other abuse.
Prior to suspending the system, an expert, trained and experienced in suspending speaker systems, should inspect
all parts and components.
ATTACHMENT TO STRUCTURES
A licensed Professional Engineer must approve the placement and method of attachment to the structure prior to
the installation of any overhead object. The following performance standards should be provided to the Professional
Engineer for design purposes: Uniform Building Code as applicable, Municipal Building Code as applicable and
Seismic Code as applicable. The installation of the hardware and method of attachment must be carried out in the
manner specied by the Professional Engineer. Improper installation may result in damage, injury or death.
