|HARMAN’s JBL Professional Introduces Next Generation VTX Line Array Series at
Winter NAMM 2012
ANAHEIM, California – HARMAN’s JBL Professional today announced the introduction of the VTX Line Array
Series—a revolutionary product that builds on the company’s 65-year heritage of loudspeaker design innovation
and groundbreaking technology development. Designed for portable and fixed-venue system operators alike, the
VTX Series features JBL’s legendary sound quality coupled with the most advanced sound reinforcement
technology and support available.
“Of all the achievements JBL has made over the years, the VTX Series stands as a milestone in the practical
application of creative engineering,” said Paul Bauman, Senior Manager, Tour Sound, JBL Professional. “VTX truly
represents the next generation in line arrays—an evolution of JBL’s industry-standard VERTEC® that heralds a new
era in performance, system integration and user-friendliness.”
The first product from the VTX Line Array Series is the VTX V25—a full-size, 3-way, high-directivity line array
element. The VTX V25 features two 2000W, 15-inch Differential Drive® woofers mounted in die-cast aluminum
baffles, with four 8-inch Differential Drive mid-range transducers and three of the revolutionary new D2 Dual-
Diaphragm Dual-Voice-Coil Compression Drivers mounted on a 3rd generation waveguide and patented RBI
Radiation Boundary Integrator® assembly.
At the heart of VTX is the D2 Dual Driver, a revolutionary device developed by JBL that dramatically improves the
sound and performance of high frequencies. D2 overcomes the limitations of conventional compression driver
technology: limited high frequency extension due to mass of the diaphragm and voice coil, and distortion
characteristics that arise due to dome breakup modes.
JBL’s patented Radiation Boundary Integrator
combines the high frequency and mid-range sections
of the VTX V25 so the transition across each band is
uninterrupted, undistorted and seamless. A patentpending,
tuned resonant absorption chamber (TRAC)
is integrated into the waveguide itself, effectively
eliminating throat-related cancellations due to back
pressure from the mid-range section. VTX’s refined
RBI waveguide implementation provides improved
horizontal coverage—broader and more stable.
The VTX Series draws from the expertise and
integration of the entire range of HARMAN
Professional audio technologies. As a result, in
addition to the best sound possible, setup, tuning,
networking and controlling the VTX Series is
efficient, intelligent and truly a system solution. For
example, the VTX Series features Crown Audio
VRack DSP and amplification. VRack is a rugged
touring rack fitted with three Crown I-Tech HD Series
power amplifiers, power input panel, and custom-

engineered input/output panels that is available in two configurations: VRack 12000 and VRack 4 x 3500 are
loaded with three IT 12000HD and three IT 4 x 3500HD amplifiers, respectively.
Apart from the performance advantage of a standard package ensuring that VTX Series enclosures are optimally
powered and processed, VRack ensures compatibility for cross rental between VTX Network Partners. Since
VRack is supplied with all components installed and internally connected, there is also no need for laborious rack
building; no chance that a component might be improperly connected; and a dramatically lower chance of
The patented workflow paradigm of the Performance Manager interface guides the system designer through the
complete system design, configuration and control process and, in many ways, the entire process feels and acts
like a simple step-by-step wizard.
Using HARMAN’s JBL HiQnet Performance Manager™ control software and with reference to measured spatial
response, circuit level gain and JBL Line Array Control Panel tapering adjustments are performed as a first step in
system tuning with the VTX V25. Once SPL and frequency response has been optimized on a circuit level, global
equalization can then be applied to the entire array to compensate for room-related effects. This patented approach
to system tuning has been specifically designed into the workflow of Performance Manager.
VTX’s patented SAFE suspension system is streamlined for speed and efficiency with improved hardware for faster
setup with fewer pinning operations and greater security. A custom-designed protective cover and dolly makes
transport easy and the suspension process fast, efficient and safe.
All suspension hardware is integrated into the enclosure and strategically positioned for fast and secure operation.
Front flip hinges and captive rear hinge bars utilizing a unique Angle Stop Mechanism (ASM) allow for efficient
assembly that is not only secure, but anti-rattle. Also included is provision for mounting a Laser Sighting Module
accessory for greater ease and precision in array focus and system tuning.
The VTX Series complies with HARMAN’s GreenEdge initiative, combining environmentally friendly design with
dramatic energy savings without compromising the excellent performance for which HARMAN products are known.
Like all JBL Professional products, the VTX Series is comprehensively tested in JBL’s power testing facilities.
Unique in the industry, during the design phase JBL power testing submits each component and system to 100
hours of continuous, high level input, ensuring that your system will deliver extraordinary sound even after years of
hard use and thousands of hours of performance.
“The VTX Series is a result of JBL’s continued effort to deliver more powerful, more compact, lightweight and
flexible sound reinforcement systems,” Bauman commented. “JBL has invested heavily in the tools necessary to
design, measure, evaluate and refine components throughout the development cycle. In addition to state-of-the-art
CAD systems, we have developed proprietary R&D tools unique to JBL. With these tools, we are assured of
meeting each product’s intended design goals, able to find opportunities for even better performance, and perhaps
most important, have the resources to develop technologies that never existed. The VTX System is a premier
example of this.”
