Calculated based on power rating and sensitivity, exclusive of power compression.

Anechoic sensitivity in free field, no additional sensitivity gains from boundary loading.

JBL continually engages in research related to product improvement. Some materials, production methods and design

refinements are introduced into existing products without notice as a routine expression of that philosophy. For this

reason, any current JBL product may differ in some respect from its published description, but will always equal or

exceed the original design specifications unless otherwise stated.

Large Houses of Worship

Variable Line Array Series (VLA Series) is a

revolutionary product providing high-impact

sound reinforcement at throw distances

beyond the reach of traditional loudspeaker

designs. The modular design concept

provides the system designer the ability to

build large line array systems for larger venue

applications or to design smaller line array

systems for use as distributed clusters in

arenas, domed stadiums and larger

performance spaces, including large houses-

of-worship.

VLA is designed specifically for permanent

installation applications where even coverage,

intelligibility, and levels capable of

overcoming crowd noise are required.

VLA modules are based on the same

advanced engineering used in the highly

successful V

ERTEC

Series line array systems.

VLA goes one step further than V

ERTEC by

providing six large format horn-loaded

modules with three horizontal horn coverage

patterns (30°, 60°, & 90°). This modular

concept provides the designer the additional

flexibility to vary the horizontal pattern within

a vertical array by incorporating different

modules with wider or narrower coverage

patterns while still maintaining the vertical

directivity.

The VLA Series uses JBL proven

technology components. The mid and high

frequency sections are horn-loaded for

maximum sensitivity and optimum pattern

control. The midrange section features the

patented technology of the CMCD82H

200 mm (8 in) cone midrange compression

driver with dual 75 mm (3 in) voice coils

coupled to a driver/phasing plug assembly

providing high output with low distortion.

The high-frequency section features the

2431H 38 mm (1.5 in) throat diameter 75 mm

(3 in) aluminum diaphragm, neodymium

high-frequency drivers. The low-frequency

section utilizes the 2226H 380 mm (15 in)

driver with a 100 mm (4 in) voice coil.

Enclosures feature 16 mm (⅝-inch) exterior

grade 12-ply birch plywood. Grilles are

powder coated 14 gauge acoustically

transparent perforated steel. For outdoor

applications JBL offers two standard levels of

weather resistance. WRC is for outdoor

placement where the loudspeaker will be

sheltered from direct exposure. WRX is for

direct exposure or more extreme

environments.
