JBL V R X 9 1 8 S Specifications

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 V ER T EC 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.
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.
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.
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.

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
