JBL作為專業揚聲器生產商,自Vertec系列揚聲器誕生之日起,一直引著線陣列揚聲器的發展方向。其強勁的高頻壓縮驅動器,波導高頻驅動技術,先進的技術組件,得到廣大用戶的青睞,出現在世界的每個重要場合,出現在世界的每個角落。

2017年,JBL更是推出了全新的VTX A12線陣列揚聲器,它的誕生使得VTX家庭產品線更完善,更多樣化,更具靈活性。

Next Generation Dual 12" Line Array Loudspeaker

JBL VTX A12 is a complete tour sound solution for mid- to large-size 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 a high-frequency waveguide design deliver unmatched performance, sensitivity and coverage. A patented JBL rigging mechanism and redesigned suspension system streamline deployment and setup. And refinements to the physical design maximize reliability and versatility, while minimizing size and dramatically reducing weight. VTX A12 isn’t just a superior line array—it’s a completely new way to approach tour sound.

TECHNOLOGY

 

 
INSIDE THE INNOVATIONS
 
Every component inside the VTX A12 loudspeaker was designed from scratch for linear performance, high output and consistent coverage. Together, the completely redesigned low-, mid- and high-frequency sections deliver the highest output per weight, improved low-frequency extension, and 90-degree directivity down to 250 Hz. 

 

HIGH-FREQUENCY SECTION
 
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 sensitivity, while reducing distortion and overall weight. 

 

MID-FREQUENCY SECTION
 
Improving upon the patented JBL Radiation Boundary Integrator (RBI), the all-new VTX A12 RBI combines four 5.5” mid-frequency drivers into the high-frequency waveguide—providing a smooth horn surface for the high frequency section. 

 

LOW-FREQUENCY SECTION
 
A lightweight 12” neodymium low frequency woofer (LF) features a 4th-generation Differential Drive design, with a new dual-voice coil, dual-magnet arrangement that increases linear excursion, power handling and sensitivity. 

 

THE NEW LOOK OF VTX A12
 
VTX A12 features a new full-face grill design that reduces the number of exposed components and protects the loudspeaker from extreme weather and road conditions. The enclosed grill helps the system achieve a higher Ingress Protection rating (IP55), and can be finished in a variety of colors to suit fixed install applications. The grill is under tension, virtually eliminating noise that can emanate from the perforated grill and degrade sound quality. 

 

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 (VT) cart in a 10-degree collapsed position. A patented internal locking mechanism makes it easy to set arrays from 0.25 to 10 degrees using selector pins. Once the system is suspended, the mechanism automatically locks the cabinet angles at the designated positions. 

 
 
 
 
SYSTEM INTEGRATION
 
   
With the VTX Series you are not just using a product, you are gaining access to an expert system. Tools for system design and all the components to analyze, configure, set up and control a VTX system are all part of the JBL commitment to total system integration and support. The goal is maximum efficiency and the highest possible level of performance in any venue, anywhere in the world.
