JBL V R X 9 1 8 S Specifications

SIMPLIFIED RIGGING

Ease of set up and takedown is critical

to ensuring high quality sound

reinforcement that meets both time and

cost restrictions. JBL’s exclusive

integral rigging hardware for the

VRX900's allows the enclosures to be

quickly and securely locked to one

another by simply swinging a hinged

bar into place and securing it with the

included quick release pins. The

optional VRX-AF or VRX-SMAF array

frame attaches to the rigging hardware

of each enclosure providing an easy to

use, elegant suspension system for

flown arrays. A second array frame

may be installed at the bottom of an

array for applications where the system

must be aimed down sharply.

VRX900 LINE ARRAY

Addressing the growing need for a small format professional sound system, JBL developed the VRX932LA and VRX928LA

Constant Curvature Line Arrays for sound rental companies, fixed installations, Musicians and DJ's looking for the ultimate in

performance and portability. Featuring the performance of high end line arrays in two compact 8 inch and 12 inch formats, including

a powered option in the 12 inch format. It is affordable, flexible and provides outstanding coverage and coherence. The VRX900

series shares components with the JBL VERTEC

®

Line Array Series, the worldwide touring industry standard. It is perfectly suited

for use in smaller venues and small to medium sound reinforcement projects. Delivering extraordinary power handling, clarity

and flexibility, the VRX900 Line Array speakers feature the hallmark of all JBL products - Stunning, legendary JBL sound.

VRX900 SUBWOOFER

For applications requiring the sonic and practical advantages of integrating the subwoofers into the flying array JBL offers the

VRX918S and the VRX915S, two compact, high power, suspendable subwoofer systems using 15 inch and 18 inch Differential

Drive

®

woofers in front loaded vented enclosures. A powered 18 inch option, VRX918SP is also available. The VRX918S was

designed specifically for use in arrays with the VRX932LA, as the VRX915S complements perfectly the VRX928LA. Both subwoofers

are equipped with a top-mounted, threaded, M20 socket that can receive the optional SS4-BK adjustable pole.

VRX915M STAGE MONITOR

The VRX915M is a dedicated, compact and lightweight 15 inch touring-class floor monitor. Its symmetrical designed enclosure

enables convenient left-right orientation. With its low stage height and JBL's latest neodymium-magnet transducers, it delivers world

class performance in the most demanding applications.

DIFFERENTIAL DRIVE

®

WOOFERS

Sound reinforcement professionals constantly ask

for more power but less weight so JBL designed

the VRX’s drivers with much less weight than

comparable drivers and yet significantly increased

its power handling and output. Super lightweight

neodymium magnets positioned inside the voice

coil of each driver, a key feature of JBL’s patented

Differential Drive woofer design, reduce the

massive steel top plates, back plates and pole

pieces found in the 'magnetic circuits' of

conventional loudspeakers. The VRX’s dual voice

coil design delivers greater power handling while

maximizing the performance of each driver. An

integrated heat sink ensures excellent heat

dissipation and consistent, reliable performance.

Overall, the VRX weighs less, has more power

capacity, lowered distortion and lower power

compression than any comparable system.

DURABLE CONSTRUCTION 

VRX900 Series enclosures are

constructed with premium quality 

birch plywood. Coated in JBL's 

rugged DuraFlex™ finish and heavily

braced the systems are extremely

durable, not to mention rigid and

resonance free. The heavy duty 

steel grilles are internally lined 

with acoustically transparent foam 

to provide additional driver protection.

QUICK CONNECTIONS

The setup for VRX900 powered

speakers is fast and easy. Simply

connect up to three loudspeakers

together by looping the power and 

audio cables from one unit to another.

One power cable and one source 

cable can drive the entire system.

POWERED BY CROWN

Designed in cooperation with Crown International, the ultra compact, high-power JBL DrivePack

®

DPC-2 amplifier module features

Crown’s Class D digital power amplification circuitry. DBT (Dual-Bridged Technology™) directly links discrete amplifier channel outputs

to each voice-coil in the Differential Drive loudspeaker. The DPC-2 incorporates Crown’s BCA™ (Balanced Current Amplification) Class-I

circuitry with temperature compensated modulation and state of the art feedback circuitry. An extraordinarily efficient passive cooling

system eliminates noisy fans. The onboard DSP controls the system performance; protection, optimization, equalization and for the

VRX932LAP, the Array Configuration Selector.

AMPLITUDE SHADING

Covering a venue with a smooth, consistent sound field is key to the success of any professional sound

reinforcement project. The VRX accomplishes this with JBL’s Array Configuration Selector, a convenient

series of switches on each enclosure that controls the output of each high-frequency section in the array.

With the VRX’s amplitude shading you can set the upper enclosures in an array configuration to deliver

more output for reaching a distant balcony while the lower enclosures can be ‘shaded back’ with less

output for the front rows of the venue. Each section of the venue can be fine tuned for a balanced,

seamless overall coverage pattern.

ARRAY TOOL

The VRX932LA and VRX928LA array tools provide visual help for the user to better understand and deploy

a VRX900 Line Array. It can be found here: http://www.jblpro.com/vrx/ARRAYTOOL.HTML. Acoustic

performance can be quickly assessed by simply creating a two dimensional view of the environment the

VRX900 system would be used in. The effect of adding systems to the array and adjustments of the

Array Configuration Selector can be quickly analyzed.

CONSTANT CURVATURE ARRAY

The challenge in designing a world-class line array is to create a controlled, coherent

coverage pattern regardless of the number of cabinets used in the array. JBL’s Constant

Curvature Array Design does that and more. The VRX waveguide mounts three compression

drivers on a continuous arc enabling them to work together acoustically as if they were a single

driver, while dramatically increasing the power handling and acoustic output when compared to 

a single driver system. Additional enclosures can be added creating an uninterrupted, continuous

arc with all of the drivers working together seamlessly as if they were one driver on a very long

waveguide. This innovative technology provides unprecedented output coherence and stunning, clear

high-frequency sound quality regardless of the configuration.
