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.

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.

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.

INTRODUCTION TO THE VRX915S The VRX915S a very compact single 15” direct radiating subwoofer is intended as companion subwoofer for the VRX928LA. The suspension system is designed for full compatibility with the VRX928LA Line Array System and with the VRX-SMAF array frame. The M20 mounting plate allows for utilization of the adjustable pole mount SS4-BK. WARNING: The VRX928LA is the only system intended for use with the VRX915S when utilizing the SS4-BK.

INTRODUCTION TO THE VRX915M The VRX915M is a dedicated, compact and lightweight, 15", two way touring-class floor monitor, with only a 375mm (14.75 in) stage height and JBL’s latest neodymium-magnet transducers. A 380 mm (15 in) 2265H patented Differential Drive® woofer handles 800 watts (continuous) and delivers accurate and precise low frequency reproduction.

INTRODUCTION TO THE VRX-AF The VRX-AF is an array frame designed to be used for suspension of the VRX932LA and VRX918S loudspeaker systems. The optional array frame kit includes the following items: • • • • • 1 2 4 2 2 x x x x x center frame side arms quick release pins drop levers 3/8˝ shackles Working Load Limit The VRX-AF, VRX932LA-AF, and VRX-SMAF array frames have been precisely engineered to work together with the VRX line of speakers as a system.
INTRODUCTION TO THE VRX-SMAF The VRX-SMAF is an array frame designed to be used for suspension of the VRX928LA and VRX915S loudspeaker systems. The optional array frame kit includes the following items: • • • • 1 2 2 2 x x x x frame quick release pins drop levers 3/8" shackles Working Load Limit The working load limit depends upon the configuration of array frame and speakers being suspended.
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.
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.
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.
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).
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.
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.
Suspension in Permanent Installations For permanent installation applications a VRX array may be suspended using M10 eyebolts. Only load-rated, forged shoulder eyebolts are to be used. A kit consisting of three (3) forged shoulder eyebolts is available from JBL Professional as part number 229-00009-01. Suspension of the VRX array must employ both top attachment points. The VRX918S and VRX915S subwoofers must always be at the top of the array.
