VTX A12 | User Manual
6 - INTRODUCTION
JBL VTX A12 is a complete tour sound solution for mid- to large-sized touring applications and high-end fixed installations. VTX A12
was designed from scratch to address the unique challenges of rental companies, FOH engineers, and tour sound production crews.
Next-generation JBL transducer technology and waveguide design deliver unmatched performance, efficiency, and coverage. A pat-
ented JBL rigging mechanism and redesigned suspension system streamline deployment and setup. The VTX A12W is acoustically and
mechanically compatible with the A12 and offers a wider (120-degree) horizontal coverage pattern. VTX A12W can be used standalone
for applications that require wide horizontal coverage or in conjunction with A12 for combination arrays. Refinements to the mechanical
design maximize reliability and versatility, while minimizing size and dramatically reducing weight. VTX A12 isn’t just a superior line ar-
ray—it’s a completely new way to approach tour sound.

KEY MESSAGES
INNOVATIVE RIGGING
VTX A12 marks a giant leap forward in how loudspeakers are
rigged and transported. Four array elements are stacked on
the vertical transporter cart for fast deployment. The rigging
features an auto-locking mechanism, which allows the selec-
tion of angles while components are on the ground; once the
system is suspended, the mechanism automatically locks cab-
inet angles in the designated positions. Set angles simply by
pulling and placing a pin—it’s that easy.
ACCESSORIES
Multiple accessory options provide flexibility in the VTX A12’s
mounting, integration and installation capabilities. Highlights
include a Base Plate that mounts the A12 on top of ground-
stacked subwoofers such as the B28. The array frame and
vertical transporter cart were purpose-built to meet both U.S.
and international truck pack dimensions for the most efficient
system transportation.
PERFORMANCE
JBL Professional is the world’s leading manufacturer of loudspeaker
systems, using custom-designed and built drivers for optimal per-
formance.
VTX A12’s high frequency (HF) section features three uniquely de-
signed drivers that combine the HF phasing plug and waveguide into
one part providing better tolerances and increased sensitivity above
10 kHz, while reducing distortion and overall weight.
The patented Radiation Boundary Integrator incorporates four 5.5-
inch mid frequency drivers into the high frequency waveguide while
providing a smooth surface for the high frequency horn.
A lightweight 12-inch low frequency woofer (LF) features a fourth-gen-
eration Differential Drive design that adds dual magnets to its dual
voice coil/dual gap construction, and a host of proprietary JBL tech-
nologies for increased excursion, power handling, and sensitivity.
