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 A12 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 JBL Line Array Calculator 3TM software (LAC-3) to check mechanical limits and ensure
compliance with local regulations. ANSI Standard E1.8 (Entertainment Technology Loudspeaker Enclosures Intended for Overhead Sus-
pension), 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 SUSPENDED ARRAY LIMITS
3.2 GROUND STACK ARRAY LIMITS
TIPS:
• The VTX A12 and VTX A12W share the same weight and physical size.
• The names “VTX A12” and “VTX A12W” are used interchangeably throughout this document.
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 Line Array Calculator 3TM 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.
NOTES:
• When the safe limit and maximum limit are the same, the array always produces a safety factor of 4:1 or higher.
• 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.
• LAC-3 will not allow array designs below the 4:1 minimum safety factor.

5 - SOFTWARE
5.1 LINE ARRAY CALCULATOR 3TM
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 achieve 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.

14
VTX A12 | 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.

15
VTX A12 | 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 - VTX A12 RIGGING SYSTEM OVERVIEW
VTX A12 cabinets include a next-generation rigging system that is easy to use, simple to understand, and highly accurate. VTX A12
enclosures are transported vertically on carts of four using the VTX A12 VT Vertical Transporter cart system accessory. During trans-
portation, all four cabinets travel collapsed with their angles 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 a VTX A12 VT cart, 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 cabinets can collapse
again and be stored on the cart.
NOTE: For the purpose of this manual, the names “A12” and “A12W” will be used interchangeably.

6.2 VTX A12 - ANGLE LOCK MECHANISM
The VTX A12 includes an innovative Angle Lock mechanism that automatically engages when the cabinets are suspended and reach
their desired angle positions. The Angle Lock mechanism consists of two main parts, the red Locking lever and the black Lock Release
button.
The system is locked when the red Locking lever is recessed into
the cabinet. When the cabinets are suspended, a sequential lock-
ing sound is heard, indicating that the system has reached its final
position and is locked. The system remains locked until the Angle
Lock mechanism has been released.
LOCKED POSITION
To de-rig the system, the Angle Lock mechanism is released so
that the cabinets can collapse again and be set on the VTX A12
VT at a 10-degree angle. Press the black Lock Release Button to
unlock the mechanism.
When the black Lock Release button is pressed, the red Locking
lever is released and moves to its unlocked position. The Lock-
ing lever is spring-loaded and maintains its position until the user
manually changes the mode. The Angle Locks are set to their
unlocked position until the cabinets are attached to the VTX A12
VT and collapsed all the way to 10 degrees.
NOTE: The red Angle Lock levers are used to secure the angle
position and prevent the cabinets from taking a different angle
when cabinets are deployed in an array. The red Angle Lock lever
is not load-bearing, and the system is safe even if they are acci-
dentally left in the unlocked position.

6.3 VTX A12 - ANGLE SELECTION
Each VTX A12 includes an Angle Selection panel on each side that is used for selecting the cabinet-to-cabinet splay angle. The options
are marked in degrees and the panel allows for eleven unique positions ranging from 0.25 degrees to 10 degrees.
VTX A12 ANGLE OPTIONS: 0.25°, 0.5°, 1°, 1.5°, 2°, 2.5°, 3°, 4°, 6°, 8°, 10°
A dedicated quick release pin is used to select an angle. Angles
are selected while the VTX A12 cabinets are on a VTX A12 VT
resting on the ground. When the system is on the ground, the
quick release pins are not under load and can be moved freely to
a desired position.
During transportation, VTX A12 cabinets should always be set to
10 degrees. This ensures that the rigging system is locked, pre-
venting any accidental movement or angle selection.
To select an angle, remove the quick release pins from the stor-
age position (10°) and set them to the desired position. After the
array has been lifted from the ground, the weight is shifted to the
quick release pins and selecting an angle is no longer an option.
CAUTION: Every quick release pin on a VTX A12 system must always be placed in a hole. Do not suspend a VTX
A12 system if any pins are hanging freely.

7 - A12 VT AND TRANSPORTATION
The VTX A12 VT Vertical Transporter is used to transport VTX A12 cabinets in groups of four. When stacked on the VTX A12 VT, all four
cabinets are set to the 10-degree (STORAGE) position, which secures the rigging system for transportation. The optional VTX A12 VT
CVR Cover can be used for additional protection.
7.1 INSTALLING VTX A12 CABINETS ON A VTX A12 VT
