Important Safety Instructions
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.
Patents
VRX series products are manufactured and sold under U.S. patents 5,748,760; 6,112,847; 6,394,223; 6,847,726; 6,774,510; D483,743; and 6,768,806.

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.
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.
