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 (AC

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 d

AMPLITUDE SHADING Amplitude Shading 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/VRX928LAs, the lower speaker (which covers the nearest listeners) may have its high-frequency output reduced. At the same time, the upper speak

Array Configuration Selector (ACS) Below is an example of applying the ACS in a three-speaker array. In this particular configuration, the ACS on the top speaker is set at +3 dB, the middle speaker at 0 dB, and the bottom speaker -3 dB. +3 dB 0 dB -3 dB Audience Bi-Amplified System In a bi-amplified system, array shading is accomplished by connecting separate amplifier channels to the HF section of each VRX932LA/VRX928LA. In larger arrays, a single amplifier channel may be used for two adjacen

DEPLOYING THE SYSTEM The VRX932LA/VRX928LA are flexible speaker systems that can be deployed in ground-supported or suspended applications. The following information will help you set up your VRX932LA/VRX928LA system safely and effectively. POLE AND TRIPOD SAFETY WARNINGS! When using stands or poles, be sure to observe the following precautions: • Check the stand or pole specification to be certain the device is designed to support the weight of the speaker. Observe all safety precautions spe

Dual VRX932LA/VRX928LA Unlike most conventional speakers, the VRX932LA/VRX928LA is designed so that a pair of speakers may be safely mounted onto a pole or tripod stand. For most applications, the forward socket of the dual angle pole socket will be used. This will tilt the lower of the two speakers at a 15° down-angle (providing coverage of the near listeners) while the upper speaker will face straight out (covering the more distant areas). Ideally, the listeners should not be able to see eit

SUSPENSION SAFETY WARNINGS! Correct use of all rigging hardware is required for secure system suspension. Careful calculations should always be performed to ensure that all components are used within their Maximum Load Limit before the array is suspended. Never exceed the maximum recommended load ratings. Prior to suspending the system, an expert, trained and experienced in flying speaker systems should be consulted. Research and understand the codes, practices, and requirements in the venues w

Maximum Array Size There are three variations of the VRX array frame. The VRX-AF supersedes the VRX932AF-LA. The VRX-SMAF is solely intended for use with the VRX928LA and VRX915S. Before suspending a VRX array, determine which version of the array frame you have and consult the table below to determine the maximum number of speakers that may be safely suspended. The subwoofers must always be at the top of the array. VRX-AF Array Frame VRX-AF Array Frame The following table defines the maximum n
