VRX932LA-1 12" Two-Way
Line Array Speaker
The VRX932LA-1 is a light-weight
(46 lb / 21 kg) compact 12" two-way line
array speaker system designed for use in
arrays of up to six units. VRX932LA-1 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 such as
JBL’s VERTEC®.
The Constant Curvature waveguide
mounts three compression drivers on a
continuous arc. When additional
VRX932LA-1 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 VRX932LA-1, the combined
power handling and acoustic output of
the system is far greater than a single
driver could achieve.
VRX932LA-1 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
HF section is shaded back to reduce
excessive level at the front of the
listening area.
One or two VRX932LA-1’s may also be
used on a tripod or over subwoofers. The
integral rigging hardware is used to
securely lock the array together while the
dual-angle pole socket provides aiming
flexibility.
As many as six VRX932LA-1 speaker
systems may be suspended in a single
array for a nominal vertical coverage of up to 90°. Suspended applications require
the JBL VRX-AF array frame (available separately). For applications in which the
array must be aimed sharply down, a second array frame may be installed to the
bottom of the array serving as a pull-back.
VRX918S subwoofers are the ideal choice for a ground-stacked or flown
VRX932LA-1 system. The SRX718S subwoofer is also compatible when suspension is
not required.

Array Configuration Selector (ACS)
Amplitude shading is a technique that allows the coverage pattern of a loudspeaker
array to be shaped by adjusting the relative acoustic output 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 VRX932LA-1s, 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. Amplitude shading of a VRX932LA-1 array may be
accomplished in passive or bi-amplified systems.
In passive mode, the Array Configuration Selector may be used. The -3 dB position
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 resulting from mutual
coupling of multiple woofers in an array.

VRX-AF Array Frame Accessory
The VRX-AF is an array frame kit designed to be used
for suspension of the VRX932LA-1 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 frame.
A minimum design factor of 7:1 is maintained for all
speaker configurations at or below thosed indicated in the
table.

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 VRX932LA-1 array. Once these are installed on the
bottom enclosure, the array frame may be attached as previously described.
Ground-stacked, upward aimed array: 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
VRX932LA-1 loudspeakers may be locked together and ground stacked using the VRX-AF array frame kit, as shown.
