• 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.
2.4 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 first 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 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 B18 suspension system and accessories comply with the 2006/42/EC Machinery Directive and have been designed following
the guidelines of BGV-C1 for a minimum safety factor of 4:1. Minimum safety factor requirements are often set by local regulations and
the JBL Line Array Calculator-3 TM (LAC-3) software should always be used to check mechanical limits.
TERMINOLOGIES:
Safe Limit: The safe limit provides the number of cabinets that can be used in an array and always produce a safety factor of 4:1 or
higher. The safety factor of an array is determined by the number of boxes, the array shape, and the overall array angle. A B18 array that
is within the safe limit will always yield a safety factor greater than 4:1 regardless of the array parameters and conditions. Designs much
greater than the safe limit, and up to the maximum limit can be achieved, but the 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 allowed under any conditions.

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 combination 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
• ANSI Standard E1.8-2005 (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 in LAC-3
produces a minimum safety factor of 5:1

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 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 Android 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.

13
VTX B18 | Rigging Manual
5.2 ARRAY LINK TM
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.

14
VTX B18 | 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 - B18 RIGGING SYSTEM OVERVIEW
VTX B18 cabinets include a six-point, spring-loaded, rigging mechanism that is easy to use and can be deployed to suspend up to 16
B18 cabinets, depending on the configuration. The B18 rigging system enables forming either standalone B18 arrays or mixed arrays
using VTX A8 full-range cabinets suspended under the B18s. All VTX A8 suspension accessories, such as the Array Frame, Suspension
Bar, and Mini Frame are compatible with the B18. When used in ground-stacked configurations, the spring-loaded rigging mechanism
maintains tension on all parts, preventing any audible artifacts from vibrations. The B18 rigging system and enclosure are front-to-back
symmetric, enabling cardioid arrays to be easily created for suspension or ground stacking.

6.2 DEPLOYING THE RIGGING BARS
Each of the six B18 rigging bars incorporates a spring-loaded mechanism. A bar automatically extends upwards once its quick release
pin (QRP) is removed. The same QRP secures the bar in place after it has been deployed.
CAUTION: No quick release pins should be left unused when deploying B18 cabinets in suspended configurations.
STEPS:
• Temporarily remove the quick release pin for each position
• The rigging bar automatically extends upwards
• Return the quick release pins to their storage positions

VTX B18 | Rigging Manual
When suspending multiple B18 cabinets together, all six rigging points (three per side) should be used for all B18 cabinets, with the ex-
ception of the top cabinet, which connects to the array frame. Two quick release pins should be used per attachment point as illustrated
below. No quick release pins should be left unused.
CAUTION: No quick release pins should be left unused when deploying B18 cabinets in suspended configurations.

7 - TRANSPORTATION OPTIONS
There are two transportation options for the B18. The first option is the vertical transportation cart (VTX B18 VT), which carries a stack
of two, three, or four B18 cabinets, in either a front-firing or cardioid configuration. The VTX B18 VT CVR, a reinforced protective cover
is available to cover and protect the subwoofers during transportation. The second option is the VTX B18 ACC accessory kit, which
includes a front face dolly for a single B18 and a protective cover. The VT option is ideal for major touring situations, where large-format
trucks are used and maximum deployment efficiency is needed. The ACC option is more agile and efficient for transportation, since B18
subwoofers can be stacked on top of other product in the trucks.
