All information presented herein is based upon materials and practices common to North America and may not directly apply to other
countries because of differing material dimensions, specifications, and/or local regulations. Users in other countries should consult with
appropriate engineering and regulatory authorities for specific 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 recom-
mended load ratings.
Before suspending any speaker system, always inspect all components (enclosure, rigging frames, pins, eyebolts, track fittings, 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 loud-
speaker models.
2.6 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 VTX 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.

3 - MECHANICAL LIMITS
The VTX A8 suspension system 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 the JBL Line Array CalculatorTM 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.

3.1 VTX A8 LIMITS - SUSPENDED ARRAY
NOTES:
• LAC-3 allows for array designs with a minimum design factor of 4:1. Anything lower than that is not allowed
• For exact mechanical limits of mixed arrays (A8s suspended under B18s) always check the design with LAC-3
• For mechanical limits when using dual Suspension Bars always check the design with LAC-3
• 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.
• For additional information on B18 limits, refer to the VTX B18 Rigging Manual

3.2 VTX A8 - 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 the JBL Line Array Calculator 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.

5 - SOFTWARE
5.1 LINE ARRAY CALCULATOR 3
Line Array Calculator 3 acoustical prediction software is used for the design and mechanical validation of VTX 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 VTX 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 VTX systems should be designed and validated using the LAC-3 software application. This is the only
way to ensure that safe mechanical conditions are met for any given configuration.

15
VTX A8| Rigging Manual
5.2 ARRAY LINKTM
JBL Array Link is a mobile companion app that works with LAC-3 software to assist technicians deploying VTX Series systems in the
field. Array Link uses a QR code to directly transfer mechanical data in real time from an array design created in LAC-3 to a mobile phone
running iOS® or Android™. All relevant rigging information and options are presented in an easy-to-understand layout. The application
can be downloaded free from the Apple App Store or Google Play Store.
Once the system designer or lead tech computes the angles for each hang in LAC-3, every member of the crew can get the correct
information for angles, attachment points, trim height, etc., either by scanning the QR code from LAC-3 directly with their device, or
getting the data from a copy shared on another user’s device. When all users onsite have the configuration data, arrays can be deployed
quickly and efficiently.

16
VTX A8| Rigging Manual
5.3 GROUND-STACKED ARRAYS IN LAC-3
Line Array Calculator version 3.5.0 or later includes mechanical safety checks for ground-stacked arrays. The software takes into con-
sideration several variables 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.

6 - A8 RIGGING SYSTEM OVERVIEW
VTX A8 cabinets include a next-generation rigging system that is easy to use, simple to understand, and highly accurate. VTX A8 enclo-
sures are transported vertically on carts of four using the VTX A8 VT Vertical Transporter cart accessory. During transportation, all four
cabinets travel collapsed and set to the 10-degree position. Cabinet-to-cabinet splay angle selection is done while the system is still on
the ground, simply by moving the angle selection quick release pin (QRP) to the desired position. When speakers are lifted off the VTX
A8 VT carts, an automatic Angle Lock mechanism engages to secure the cabinets to the selected position. The cabinets maintain their
splay positions until the user releases the Angle Lock mechanism, at which point the cabinet angles collapse back to 10 degrees and
the cabinets can be stored on the cart.

6.2 ANGLE LOCK MECHANISM
VTX A-Series cabinets include an innovative Angle Lock mechanism that automatically engages to fix the angles at the selected po-
sitions when the system is suspended. Angles can be preselected while the system is still on the ground, eliminating extra steps. The
Angle Lock mechanism consists of two main parts: the red LOCKING LEVER and the black RELEASE BUTTON. The system is locked
when the locking lever is recessed into the cabinet, and remains locked until the Angle Lock mechanism is released. When it’s time to
de-rig the system, pressing the RELEASE BUTTON disengages the Angle Lock mechanism, which allows the cabinets to collapse again
to an angle of 10 degrees for travel on the transportation cart.

6.3 ANGLE SELECTION
Every VTX A8 has an Angle Selection panel on either side of the cabinet. These panels are used to select the cabinet-to-cabinet splay
angle. The panels offer eleven unique positions, labeled in degrees. The positions range from 0.25 to 10 degrees.
VTX A8 ANGLE OPTIONS: 0.25°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 4°, 6°, 8°, 10°
A dedicated quick release pin is available for setting the angle. Angles are selected while VTX A8 cabinets sit on a VTX A8 VT cart rest-
ing on the ground. Since the quick release pins are not under load when the system is on the ground, they can be moved freely to the
desired position. During transportation, VTX A8 cabinets should always be set to 10 degrees. This ensures the rigging system is locked,
preventing any accidental movement or unintended change of angle.
To select an angle, remove the quick release pins from the storage position (10°) and set them to the position for the desired angle. Lifting
the array from the ground shifts weight to the quick release pins, making angle selection no longer possible.
CAUTION: Every quick release pin in a VTX A8 system must be set in a hole before the array is flown. Do not sus-
pend a VTX A8 system if any pins hang free.

7 - A8 TRANSPORTATION
The VTX A8 VT Vertical Transporter carries four VTX A8 cabinets for travel. All four cabinets should be set to the 10-degree (STORAGE)
position when stacked on the VTX A8 VT to secure the rigging for transportation. The optional VTX A8 VT CVR cover can be used for
additional protection.
7.1 INSTALLING VTX A8 CABINETS ON A VT
VTX A8 cabinets should be installed on a VTX A8 VT one by one, starting with the lowest cabinets in the array.
STEPS:
• Use the four front and rear A8 quick release pins to secure the first VTX A8 cabinet to the VTX A8 VT.
• Select the 10-degree (STORAGE) position for the cabinet and set the red locking lever to the locked position.
