5 - SOFTWARE
5.1 - LINE ARRAY CALCULATOR 3 TM
LAC is a simulation software for designing and predicting JBL VTX Series systems. LAC predicts the acoustical performance cover-
age of Line Array systems as well as flown and ground stacked subwoofer arrays. Enhanced acoustical modeling includes color SPL
mapping, 0 dB Isobar, and SPL attenuation modes with the frequency response and SPL based on JBL’s DSP presets. Up to 8 virtual
microphones can be placed in the venue for accurate position-dependent response prediction. Additionally, subwoofer modeling is
now offered. Subwoofer delay values can be generated for electronic subwoofer array steering (EDS) using the built-in calculator.
Beyond the acoustical prediction, LAC is used for mechanical validation of all used suspension hardware. Weight limits are calculat-
ed in real time for single or dual-point suspensions. An array design factor is calculated that can be used for designing an array within
local regulation limits. Safety warning massages are displayed when an unsafe configuration has been selected. Array statistics like,
array size, depth and weight are also calculated.

VT X A12 | Rigging Manual

5.2 - ARRAY LINK TM
JBL Array Link is a mobile companion app that works in conjunction with JBL’s latest LAC software to assist technicians deploying
JBL VTX Series systems. Array Link uses a QR code system to transfer all array mechanical information from the main LAC appli-
cation to a mobile phone – this transfer is done directly and in real time. All relevant rigging information and options are presented
in an easy-to-understand layout. The application is compatible with iOS and Android and can be obtained from the respective app
store for each OS.
The intended workflow for the Array Link app is for the system designer or lead tech to compute all the angles needed for each hang,
and then transmit the information onto their device. This information can then be shared with other users of the app onsite via their
own copy of the Array Link app, or through the other technicians scanning the QR code in LAC with their own device. Once all of
the users have the information they need, arrays can be deployed quickly and efficiently as every member of the crew has the same
correct information for angles, attachment points, trim height, etc.

KEY MESSAGES
PERFORMANCE
JBL Professional is the world’s leading manufacturer of loudspeaker
systems, using custom designed and built drivers for optimal perfor-
mance.
VTX A12’s new high-frequency (HF) section features three uniquely
designed drivers that combine the HF phasing-plug and waveguide into
one part, which helps provide better tolerances and increased sensi-
tivity above 6 kHz, while reducing distortion and overall weight.
Its all-new patented JBL Radiation Boundary Integrator combines
four 5.5” mid-frequency drivers into the high-frequency waveguide—
providing a smooth horn surface for the high-frequency section.
A lightweight 12” low-frequency woofer (LF) features a 4th generation
Differential Drive design, a new dual voice coil, dual magnet and a
host of proprietary JBL technologies for increased excursion, power
handling and sensitivity.
INNOVATIVE RIGGING
VTX A12 marks a giant leap forward in how the loudspeakers
are rigged and transported. To facilitate quicker deployment,
array elements are stacked four per vertical transporter cart
in a 10-degree collapsed position. A patented internal locking
mechanism makes it easy to set arrays at up to 1/4-degree
increments using selector pins.
ACCESSORIES
The completely redesigned VTX A12 Array Frame is the lightest
in its class. At 41 kg. (90 lbs) the lightweight frame allows the
system to be deployed in a variety of use cases and venues.
Both the cart and frame were purposefully engineered to meet
both U.S. and European truck pack dimensions to help produc-
tion companies transport the system more effectively.

7 - 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
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 QRP (quick release pin) to the desired position. When
speakers are lifted off the VTX A12 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 cabinets
can collapse again and be stored on the cart.

7.2 - VTX A12 - ANGLE-LOCK MECHANISM
VTX A12 includes an innovative Angle-Lock mechanism that automatically engages when the cabinets are suspended and reach the
desired angle position. The Angle-Lock mechanism consists of two main parts, the RED LOCKING LEVER and the black RELEASE
BUTTON.
The system is locked when the RED locking lever is recessed
into the cabinet. When the cabinets are suspended, a sequen-
tial locking sound is audible that indicates that the system
reached the final position and is locked. The system will remain
locked until the Angle-Lock mechanism has been released.
LOCKED POSITION
When it’s time 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 10-degrees. Press the release button to
unlock the mechanism.
When the button is pressed, the RED locking lever is released
and moves to the unlocked position. The RED locking lever is
spring loaded and will maintain its position until the user man-
ually changes the mode. The Angle-Locks are set to the unlock
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
accidentally left in the unlocked position.

7.3 - VTX A12 - ANGLE SELECTION
Each VTX A12 includes two Angle Selection panels (one on each side) that are used for selecting the cabinet-to-cabinet splay angle.
The options are marked in degrees and the panel allows for 11 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 available for selecting the an-
gles. Angles are selected when the VTX A12 cabinets are set
on the VTX A12 VT and resting on the ground. When the sys-
tem is on the ground, the quick release pins are not under load
and can freely move to the desired position.
During transportation, VTX A12 cabinets should always be set
to 10-degrees. This ensures that the rigging system is locked,
preventing 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: All quick release pins on a VTX A12 system must always be placed in a hole. Do not suspend
VTX A12 system if pins are freely hanging

8 - A12 VT AND TRANSPORTATION
The VTX A12 Vertical Transporter is used to transport VTX A12 cabinets in groups of 4. When stacked on the VT, all 4 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.
8.1 - INSTALLING VTX A12 CABINETS ON A VTX A12 VT
At the first time of use, VTX A12 cabinets should be installed on the VTX A12 VT one by one starting with the lowermost cabinets.
STEPS:
• Start by installing the first VTX A12 cabinet to the VTX A12 VT
• Use the 4 front and rear A12 Quick Release Pins to secure the cabinet on to the Vertical Transporter

8.2 - INSTALLING THE TOP PART OF THE VTX A12 VT
The VT-TOP connects to the top most cabinet of a stack to create a robust and defined footprint that stabilizes the carts during
transportation. Because of it’s flat profile, other gear can be placed above VTX A12 carts for a more efficient truck pack.
STEPS:
• Lower the VT-TOP on to the topmost VTX A12 cabinet. Make sure the 4 rigging corners of the A12 cabinet engage with
the VT TOP
• Secure the VT-TOP by installing the 4 Quick Release Pins on to the topmost VTX A12 cabinet
