Important Safety Instructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in accordance with manufacturer’s
instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or
other apparatus that produce heat.
9. Only use attachments / accessories specified by the manufacturer.
10. Use only with a cart, stand, bracket, or table
specified by the manufacturer or sold with the apparatus. When a cart is used, use caution when moving
the cart / apparatus combination to avoid injury from
tip-over.
11. Refer all servicing to qualified service personnel. Servicing is required when an
apparatus has been damaged in any way, such as power-cord or plug is damaged, liquid has been spilled, or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
12. To reduce the risk of fire or electric shock, do not expose this apparatus to rain
or moisture.
13. Hearing damage, prolonged exposure to excessive SPL, the loudspeaker
is easily capable of generating sound pressure levels (SPL) sufficient to
cause permanent hearing damage to performers, production crew and
audience members. Caution should be taken to avoid prolonged exposure
to SPL in excess of 90 dB.
The VRX Series loudspeakers covered by this
manual are not intended for fixed installation in
outdoor or high moisture environments. Moisture
can damage the speaker cone and surround
and cause corrosion of electrical contacts and
metal parts. Avoid exposing the speakers to
direct moisture. Keep speakers out of extended
or intense direct sunlight. The driver suspension
will prematurely dry out and finished surfaces may
be degraded by long-term exposure to intense
ultra-violet (UV) light.
The VRX Series speakers can generate considerable
energy. When placed on a slippery surface such as
polished wood or linoleum, the speaker may move
due to its acoustical energy output. Precautions
should be taken to assure that the speaker does not
fall off a stage or table on which it is placed.

INTRODUCTION TO THE VRX932LA
The VRX932LA is a two-way, line-array loudspeaker system intended for use in arrays of up to six enclosures.
Three high-frequency drivers are mounted to the Constant Curvature waveguide which is designed so that
multiple enclosures may be arrayed with no discontinuity in the vertical coverage pattern. As a result, the array
will behave in much the same way as would a single loudspeaker. Array coverage may be adjusted by means
of the Array Configuration Selector (ACS), a feature that provides amplitude shading (see page 15 & 16) when
the system is used in passive mode. Integral rigging hardware, a dual angle pole socket and an accessory array
frame provide for a variety of mounting and suspension options.
*NOTE: The VRX932LA-WH is designed for fixed install situations where white loudspeakers are required to
match existing decor. White versions therefore do not have handles, feet or pole mount features.

INTRODUCTION TO THE VRX928LA
The VRX928LA – the smaller version of the VRX932LA is a light-weight, compact, 8", two-way line-array
speaker system designed for use in arrays of up to six units. VRX928LA 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. The VRX928LA offers all the same features as the VRX932LA. As with the VRX932LA, the Array
Configuration Selector (ACS) makes it possible to distribute the sound more evenly over the entire audience
area, by reducing the output near the stage and increasing it for the far to reach rear areas. (See page 15 & 16)
NOTE: A white version is available for this product through our custom shop.

INTRODUCTION TO THE VRX918S
The VRX918S is a compact, single, 18" direct radiating subwoofer intended for use in suspended arrays or
ground-supported applications. The suspension system is designed for full compatibility with the VRX932LA
line-array speaker system and the VRX-AF array frame.
*NOTE: The VRX918S-WH is designed for fixed installation situations where white loudspeakers are required to
match existing decor. White versions therefore do not have handles, feet or pole mount features.
