SIMPLIFIED RIGGINGEase of set up and takedown is criticalto ensuring high quality soundreinforcement that meets both time andcost restrictions. JBL’s exclusiveintegral rigging hardware for theVRX900's allows the enclosures to bequickly and securely locked to oneanother by simply swinging a hingedbar into place and securing it with theincluded quick release pins. Theoptional VRX-AF or VRX-SMAF arrayframe attaches to the rigging hardwareof each enclosure providing an easy touse, elegant suspension system forflown arrays. A second array framemay be installed at the bottom of anarray for applications where the systemmust be aimed down sharply.VRX900 LINE ARRAYAddressing the growing need for a small format professional sound system, JBL developed the VRX932LA and VRX928LAConstant Curvature Line Arrays for sound rental companies, fixed installations, Musicians and DJ's looking for the ultimate inperformance and portability. Featuring the performance of high end line arrays in two compact 8 inch and 12 inch formats, includinga powered option in the 12 inch format. It is affordable, flexible and provides outstanding coverage and coherence. The VRX900series shares components with the JBL VERTEC® Line Array Series, the worldwide touring industry standard. It is perfectly suitedfor use in smaller venues and small to medium sound reinforcement projects. Delivering extraordinary power handling, clarityand flexibility, the VRX900 Line Array speakers feature the hallmark of all JBL products - Stunning, legendary JBL sound.VRX900 SUBWOOFERFor applications requiring the sonic and practical advantages of integrating the subwoofers into the flying array JBL offers theVRX918S and the VRX915S, two compact, high power, suspendable subwoofer systems using 15 inch and 18 inch DifferentialDrive® woofers in front loaded vented enclosures. A powered 18 inch option, VRX918SP is also available. The VRX918S wasdesigned specifically for use in arrays with the VRX932LA, as the VRX915S complements perfectly the VRX928LA. Both subwoofersare equipped with a top-mounted, threaded, M20 socket that can receive the optional SS4-BK adjustable pole.VRX915M STAGE MONITORThe VRX915M is a dedicated, compact and lightweight 15 inch touring-class floor monitor. Its symmetrical designed enclosureenables convenient left-right orientation. With its low stage height and JBL's latest neodymium-magnet transducers, it delivers worldclass performance in the most demanding applications.DIFFERENTIAL DRIVE® WOOFERSSound reinforcement professionals constantly askfor more power but less weight so JBL designedthe VRX’s drivers with much less weight thancomparable drivers and yet significantly increasedits power handling and output. Super lightweightneodymium magnets positioned inside the voicecoil of each driver, a key feature of JBL’s patentedDifferential Drive woofer design, reduce themassive steel top plates, back plates and polepieces found in the 'magnetic circuits' ofconventional loudspeakers. The VRX’s dual voicecoil design delivers greater power handling whilemaximizing the performance of each driver. Anintegrated heat sink ensures excellent heatdissipation and consistent, reliable performance.Overall, the VRX weighs less, has more powercapacity, lowered distortion and lower powercompression than any comparable system.DURABLE CONSTRUCTIONVRX900 Series enclosures areconstructed with premium qualitybirch plywood. Coated in JBL'srugged DuraFlex™ finish and heavilybraced the systems are extremelydurable, not to mention rigid andresonance free. The heavy dutysteel grilles are internally linedwith acoustically transparent foamto provide additional driver protection.QUICK CONNECTIONSThe setup for VRX900 poweredspeakers is fast and easy. Simplyconnect up to three loudspeakerstogether by looping the power andaudio cables from one unit to another.One power cable and one sourcecable can drive the entire system.POWERED BY CROWNDesigned in cooperation with Crown International, the ultra compact, high-power JBL DrivePack® DPC-2 amplifier module featuresCrown’s Class D digital power amplification circuitry. DBT (Dual-Bridged Technology™) directly links discrete amplifier channel outputsto each voice-coil in the Differential Drive loudspeaker. The DPC-2 incorporates Crown’s BCA™ (Balanced Current Amplification) Class-Icircuitry with temperature compensated modulation and state of the art feedback circuitry. An extraordinarily efficient passive coolingsystem eliminates noisy fans. The onboard DSP controls the system performance; protection, optimization, equalization and for theVRX932LAP, the Array Configuration Selector.AMPLITUDE SHADINGCovering a venue with a smooth, consistent sound field is key to the success of any professional soundreinforcement project. The VRX accomplishes this with JBL’s Array Configuration Selector, a convenientseries of switches on each enclosure that controls the output of each high-frequency section in the array.With the VRX’s amplitude shading you can set the upper enclosures in an array configuration to delivermore output for reaching a distant balcony while the lower enclosures can be ‘shaded back’ with lessoutput for the front rows of the venue. Each section of the venue can be fine tuned for a balanced,seamless overall coverage pattern.ARRAY TOOLThe VRX932LA and VRX928LA array tools provide visual help for the user to better understand and deploya VRX900 Line Array. It can be found here: http://www.jblpro.com/vrx/ARRAYTOOL.HTML. Acousticperformance can be quickly assessed by simply creating a two dimensional view of the environment theVRX900 system would be used in. The effect of adding systems to the array and adjustments of theArray Configuration Selector can be quickly analyzed.CONSTANT CURVATURE ARRAYThe challenge in designing a world-class line array is to create a controlled, coherentcoverage pattern regardless of the number of cabinets used in the array. JBL’s ConstantCurvature Array Design does that and more. The VRX waveguide mounts three compressiondrivers on a continuous arc enabling them to work together acoustically as if they were a singledriver, while dramatically increasing the power handling and acoustic output when compared toa single driver system. Additional enclosures can be added creating an uninterrupted, continuousarc with all of the drivers working together seamlessly as if they were one driver on a very longwaveguide. This innovative technology provides unprecedented output coherence and stunning, clearhigh-frequency sound quality regardless of the configuration.
