compression driver design.
Constant Curvature waveguide for
unprecedented array coherence.
Integral rigging hardware for simple
connection of enclosures and optional
array frame. Dual angle pole socket for
aiming flexibility.
Array Configuration Selector permits “array
shading”.
Application:
Music playback and sound
reinforcement in mid-size venues.
Entertainers, corporate A/V professionals and
sound system hire companies.
Permanent Installation.
The VRX932LAP is a powered, lightweight, compact 12" two-way line-array
speaker system designed for use in arrays
of up to five units. VRX932LAP is the ideal
choice when line-array performance is
needed but the venue size doesn't call for
the very long-throw characteristics of larger
line-arrays and a fast and easy setup is
vital.
The Constant Curvature waveguide
mounts three compression drivers on a
continuous arc. When additional
VRX932LAP speakers are added to the
array the uninterrupted arc continues. In
effect, all the drivers work together as if
they were a single driver on a very long
waveguide. Since there are three drivers in
each VRX932LAP, the combined power
handling and acoustic output of the system
is far greater than a single driver could
achieve.
VRX932LAP uses “amplitude shading” to
shape the coverage of the array. Switches
on the input plate allow, for example, the
upper box in an array to reach a distant
balcony while the lower box is shaded
back to reduce excessive level at the front
of the listening area. This yields to a more
coherent sound field and less feedback
problems.
One or two VRX932LAP’s may also be
used on a tripod or over subwoofers. The
integrated rigging hardware is used to
securely lock the array together while the
dual-angle pole socket provides aiming
flexibility.
As many as five VRX932LAP speaker
systems may be suspended in a single
array for a nominal vertical coverage of up
to 75°. Suspended applications require the
JBL VRX-AF array frame or eye bolts
(available separately).

of some of the devices in the array. Most often, array shading involves
only the mid and high-frequency sections of the array. In a simple system
consisting of three VRX932LAP’s, the lower speaker (which covers the
nearest listeners) may have its high-frequency output reduced. At the
same time, the upper speaker may have its high frequency output
increased. The overall sound-power in the room is unchanged but the
distribution of acoustic energy to the audience is far more uniform.
The -3 dB position of the HF output level selector will typically be
used for the speaker(s) in an array that are covering the nearest listening
area. The +3 dB position will be used for the speaker(s) covering the
more distant areas, or to compensate for the low-frequency build-up

VRX-AF Array Frame Accessory
The VRX-AF is an array frame kit designed to be used
for suspension of the VRX932LAP line array loudspeaker.
The optional array frame kit includes an array frame, four
quick release pins, a pair of forged 3/8" shackles, and a
pair of drop levers.
The following table defines the maximum number of
speakers that may be suspended using the VRX-AF. A
minimum design factor of 7:1 is maintained for all
speakers configuration at or below those indicated in the
table:
Maximum number of VRX918SP in array: 023344
Maximum number of VRX932LAP in array: 543210
For some applications, it may be necessary to pull back the array from the bottom in order to achieve the
desired coverage. Every VRX-AF is supplied with a spare set of quick release pins and a pair of spare drop levers
that are used to adapt a second array frame to the bottom of a VRX932LAP array. Once these are installed on the
bottom enclosure, the array frame may be attached as previously described.
Ground-Stacked, Upward Firing Arrays: Applications such as covering stadium bleachers from the playing field
may be addressed by installing the VRX-AF array frame to the bottom of the array as described above. Up to four
VRX932LAP loudspeakers may be locked together and ground stacked using the VRX-AF array frame kit, as
shown.
