1.5 ARE YOU NEW TO RIGGING?
If you are new to rigging, you should:
• Know the rules for safe rigging.
• Attend a safe rigging seminar.
• Meet and establish a relationship with a licensed mechanical or structural engineer. Get in the habit of asking them questions in-
stead of assuming their answers. Learn from what they tell you.
• Research and understand the codes, practices, and requirements of the venues where you intend to operate your sound system.
1.6 INSPECTION AND MAINTENANCE
Suspension systems are comprised of mechanical devices and, as such, 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 a speaker until the proper corrective action has been taken.
Installed systems should be inspected at least once a year. The inspection must 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 SRX900 systems must be inspected for fatigue at least once a year or as required
by local ordinance. The inspection must 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 must be checked for possible spin-out of the enclosure.
For all other hardware and fittings, refer to the hardware manufacturer’s inspection and maintenance guidelines for process.

2 - MECHANICAL LIMITS
The SRX900 Series products and accessories comply with the 2006/42/EC Machinery Directive and have been designed following the
guidelines of DGUV regulation 17 (BGV-C1) for a minimum safety factor of 4:1. Minimum safety factor requirements for suspended arrays
are often set by local regulations. Use JBL Line Array Calculator 3 software to check mechanical limits and ensure compliance with local
regulations. ANSI Standard E1.8 (Entertainment Technology Loudspeaker Enclosures Intended for Overhead Suspension), Section 5.3.4,
specifies a minimum safety factor of 5:1. If compliance with the ANSI standard is needed, make sure that the array design produces a
minimum safety factor of 5:1.

2.1 SUSPENDED ARRAY
NOTES:
• LAC-3 allows for array designs with a minimum design factor of 4:1. Anything lower than that is not allowed.
• Safe and maximum limits are only applicable to the specified accessory (i.e. base plate or array frame). When several accessories
are combined (for example, ground-stacked arrays with a base plate and subwoofers underneath), the design should always be
evaluated and checked with LAC-3.
• Safe and maximum limits for base plate accessories are specified for standalone use. Limits might differ when base plates are at-
tached to subwoofers or other structures.
ACCESSORY NOTES SAFE LIMIT MAXIMUM LIMIT

2.2 GROUND-STACKED ARRAYS
TERMINOLOGY:
Safe Limit: The safe limit provides the number of cabinets that can be used in an array while maintaining a safety factor of 4:1 or higher.
The safety factor of an array is determined by the number of cabinets, the array shape, and the overall array angle. An array constructed
within the safe limit will always yield a safety factor greater than 4:1 regardless of array parameters and conditions. Ground-stacked ar-
rays within the safe limit are stable under normal conditions. Designs exceeding the safe limit and up to the maximum limit are possible,
but JBL Line Array Calculator 3 software should be used to check mechanical safety for the given configuration.
Maximum Limit: Arrays larger than the maximum limit are not allowable under any conditions.
CAUTION: Limits for ground-stacked arrays always assume that the stacking surface (floor or stage) is flat. Do not
deploy ground-stacked arrays on non-flat surfaces to avoid tipping hazards.

4 - SOFTWARE
4.1 LINE ARRAY CALCULATOR 3
Line Array Calculator 3 acoustical prediction software is used for the design and mechanical validation of SRX900 Series line array
systems. Using LAC-3 is a three-step process. First, venue dimensions are defined using either X/Y/Z coordinates or the fast distance/
angle method. Second, array configurations are built from SRX900 Series loudspeaker models. Third, virtual measurement microphones
and a suite of built-in DSP functions are applied to make predictions of the system’s coverage and the linearity that will be delivered
by the defined array configuration in the specified space. Loudspeaker quantities and models, splay angles, and array aiming can be
modified until prediction shows that the desired coverage is attained throughout the venue. The built-in coverage-and-delay calculator
determines subwoofer delay values for electronic delay steering (EDS) that achieves optimal low frequency coverage.
Beyond acoustical predictions, LAC-3 validates the mechanical properties of arrays and selected JBL accessories. Configuration limits
are calculated in real time, for either suspended or ground-stacked arrays, based on array parameters such as the number of cabinets,
cabinet-to-cabinet splay angles, overall array aiming, and selected accessories. In the case of suspended arrays, a safety factor is cal-
culated to aid in designing systems that conform to local regulations. Warnings and error messages notify the user when an array or a
specific accessory is outside safe working limits. For ground-stacked arrays, a tipping factor calculated from a complex set of variables
suggests whether an array design is likely to be stable, potentially unstable, or unsafe. Array statistics like array size, depth, and weight
are also calculated, and a PDF report facilitates system deployment. Mechanical data can be transferred to JBL’s Array LinkTM app run-
ning on an iOS® or AndroidTM mobile phone using a QR code, with no need for internet connectivity. All relevant rigging information and
options are presented in an easy-to-understand layout.
CAUTION: All SRX900 Series systems should be designed and validated using LAC-3 software, this is the only way
to ensure that safe mechanical conditions are met for any given configuration.

4.2 SUSPENDED ARRAYS
Line Array Calculator checks the mechanical safety of suspended arrays and takes into consideration all variables that can affect the
mechanical safety and safety factors. The software validates the mechanical stresses on the enclosures, speaker rigging components,
and all accessories used as part of an array. Parameters like array down angle and curvature are considered and a safety factor is
generated for the given configuration. The generated safety factor value represents the minimum of any components used, and values
are always rounded down.
A red banner appears at the top of the array views when the
software detects a mechanical error. The banner explains the
issue, and some configurations might include more than one
error. In that case, the software will present the additional mes-
sages as the errors are cleared. Configurations generating a
mechanical error should never be used as their safety factor
falls under the minimum of 4:1. The safety factor generated by
the application can be used to design arrays with safety factors
other than 4:1 and based on local regulations.
In addition to mechanical and safety errors, the software notifies
of configurations that cannot be realized in real life. An example
of such a condition is when the center of gravity of an array falls
outside of the footprint of the array frame. In this case, the error
can be cleared by changing the down angle or using a pull-back
at the bottom of the array.

4.3 GROUND-STACKED ARRAYS
Line Array Calculator checks for the mechanical safety for ground-stacked arrays. The software takes into consideration several vari-
ables that can affect the stability of an array, including outside factors such as someone pushing on an array. Based on this data, LAC-3
generates a safety assessment factor and notifies the user of potential mechanical or stability problems. Errors and warnings generated
fall into one of the following categories:
No errors or messages
In this case, the array is stable under normal conditions and can be used as is. The array
also complies with the mechanical limits set by JBL for the speakers and selected acces-
sories.
WARNING: Stability Hazard! - Stack Could Become Unstable - Secure to Ground
This message is an alert that the array is potentially unstable and a tipping hazard condition
has been detected. The user is responsible for securing the array to the ground, stage, or
other structure that can provide additional support and is rated for the weight of the array.
This message may also be warning of external factors that can influence stability, such as
someone accidentally pushing the array.
Configuration exceeds the maximum number of boxes allowed
This message is presented when the specified array design exceeds the mechanical limits
set by the JBL team for the speakers or selected accessories. Array designs that trigger this
message should not be used under any conditions, as they can lead to hardware damage
and/or injury.
Center of Gravity
Invalid CG Location
This message is presented when the center of gravity of an array design exceeds the foot-
print of the selected accessory. Array designs that trigger this message should not be used
under any conditions, as they can lead to hardware damage and/or injury.

5 - RIGGING SYSTEM OVERVIEW
SRX900 Series line array cabinets include an intuitive three-point rigging system. Angles are preselected while the system is still on the
ground using the link bar, which extends vertically to the cabinet above. When an array is suspended, angles are locked using the stop
pin. When it is time to de-rig the system, removing the stop pin allows the cabinets to collapse again for storage and transportation.

5.2 ANGLE SELECTION
Every SRX906LA and SRX910LA has a single angle selection plate on the center rear of the cabinet. These plates are used to select the
cabinet-to-cabinet splay angle. This panel offers 13 unique positions, labeled in degrees.
SRX906LA AND SRX910LA ANGLE OPTIONS: 0.5 °, 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, 11°,12°
CAUTION: Every quick release pin in an SRX900 Series system must be set in a hole before the array is flown. Do
not suspend an SRX900 Series system if any pins hang free.
When selecting angles on a stack of SRX900 Series cabinets, always start at the top cabinet and work down to the lowest. Angles are
selected while SRX900 Series cabinets are on the carts and resting on the ground. Since the rigging mechanism is not under load when
the system is on the ground, the link bar can be moved freely to the desired position.
To select an angle, remove the angle pin from the 12˚ STORAGE position and extend the link bar upwards. Align the link bar indicator
with the desired angle indicator on the angle selection plate and re-insert the pin into the corresponding angle hole. Lifting the array from
the ground shifts weight to the quick release pins, making angle selections no longer safe or possible.

6 - TRANSPORTATION
Each component in the SRX900 Series has a convenient and efficient transportation system. The SRX906LA and SRX910LA are both
transported in stacks of four cabinets with their angles fully collapsed. The SRX906LA cabinets ride inside of a rugged road case and
the SRX910LA cabinets travel on a vertical transport cart. Both the SRX918S and SRX928S subwoofers have threaded M10 mounting
holes for casters, allowing users to install the ACK1 caster kit for moving the subwoofers around. Optional soft covers are available for
the SRX910LA, SRX918S, and SRX928S to protect the cabinets during transport.
