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 exposuro SPL in excess of 90 dB.
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 exte\
nded 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 en\
ergy 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-1
The VRX932LA-1 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 waveg\
uide 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 14 & 15) when
the system is used in passive mode. Integral rigging hardware, a dual an\
gle pole socket and an accessory array
frame provide for a variety of mounting and suspension options. VRX932LA\
 and VRX932LA-1 are completely
interchangeable and can be used together.  When operated in passive mode, frequency response characteristics
are exactly the same and both can be used in the same array.
NOTE:The VRX932LA-1WH is designed for fixed install situations where white lo\
udspeakers are required to
match existing decor. White versions therefore do not have handles, feet or pole mount featu\
res.

							INTRODUCTION TO THE VRX928LALA
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 doesnt 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 fa\
r to reach rear areas. (See page 14 & 15)
NOTE:The VRX928LA-WH is designed for fixed install situations where white lou\
dspeakers are required to
match existing decor. White versions therefore do not have handles, feet or pole mount featu\
res.
