Bringing the versatility of its VERTEC Series line array to performers and smaller venues, JBL Professional today introduced the new VRX932LA portable line array system. The VRX932LA is a compact 12-inch, two-way line array loudspeaker designed for use in arrays of up to six units. Each speaker has a 15-degree (nominal) vertical coverage angle. This means that a single enclosure or arrays consisting of 2 or 3 speakers can provide practical vertical coverage. This system is designed for smaller environments requiring line array performance without the long-throw characteristics of larger systems.
"Until now, most line array speakers have been designed for use in very large, extremely high-power systems in large venues," said Gerry Tschetter, Director of Portable PA Marketing, JBL Professional. "The VRX932LA is built for smaller venues than the VERTEC line but not to a lower standard. In fact, the VRX932LA shares components with the renowned VT4888 and VT4887,"
The VRX932LA is not limited to use in suspended arrays. One or two VRX932LA speakers may also be used on a tripod or on a pole over SRX718S subwoofers. This flexibility will make it a welcome addition for performers as well as A/V rental companies. An integral rigging system supports flying (using the available JBL VRX932-AF array frame) or secure stacking.
The VRX932LA uses JBL's patented Differential Drive 12-inch woofer with dual voice coils and magnetic gaps and a neodymium magnet, allowing a few ounces to replace pounds of conventional magnet material. The Differential Drive design greatly reduces weight while increasing power capacity, decreasing distortion, and reducing power compression.
The Constant Curvature Array (CCA) waveguide mounts three compression drivers on a continuous arc. When additional VRX932LA speakers are added to the array, the uninterrupted arc continues. Whether a single VRX932LA or a maximum array of six is being used, the output from the high-frequency drivers sums with coherence. In effect, all the drivers work together as if they were a single driver on a very long waveguide, according to the company. But since there are three high-frequency drivers in each VRX932LA, the combined power handling and acoustic output of the system is far greater than a single driver could achieve.
Like larger line arrays, the coverage of the VRX932LA array may be adjusted. However, the relative angles between enclosures are fixed in order to maintain the Constant Curvature character of the array. Instead, the VRX932LA uses "amplitude shading" to shape the coverage of the array. The Array Configuration Selector switches on the input plate allow, for example, the upper box in an array to reach a distant balcony while the lower box of the array is shaded back to reduce excessive level at the front of the audience area.
VRX932LA Addressing the growing need for a small format professional sound system, JBL developed the VRX932LA Constant Curvature Line Array for sound rental companies, fixed installations and musicians looking for the ultimate in performance and portability. Featuring the performance of high end line arrays in a compact 12" two-way format that is affordable and flexible and provides outstanding coverage and output coherence, the VRX shares components with the JBL VERTEC Line Array Series, the worldwide touring industry standard. Perfectly suited for use in smaller venues and small to medium sound reinforcement projects, the VRX was designed as a more compact and portable version of the VERTEC Line Array. Delivering extraordinary power handling, clarity and flexibility, the VRX932LA features the hallmark of all JBL products - Stunning, legendary JBL sound.
Subwoofers For applications requiring the sonic and practical advantages of integrating the subwoofers into the flying array JBL offers the VRX918S, a compact, high power, suspendable subwoofer system using an 18" Differential Drive woofer in a front-loaded, vented enclosure. The VRX918S was designed specifically for use in arrays with the VRX932LA Line Array speaker and VRX-AF Array Frame. It may also flown in arrays consisting entirely of VRX918S or ground stacked. The VRX918S is equipped with a top-mounted, threaded, 20 mm socket that can receive the optional SS4-BK pole. Users who don't require a suspendable subwoofer can opt for the acoustically identical SRX718S sub.
Constant Curvature Array The challenge in designing a world-class line array is to create a controlled, coherent coverage pattern regardless of the number of cabinets used in the array. JBL's Constant Curvature Array Design does that and more. The VRX waveguide mounts three compression drivers on a continuous arc enabling them to work together acoustically as if they were a single driver, while dramatically increasing the power handling and acoustic output when compared to a single driver system. Additional enclosures can be added creating an uninterrupted, continuous arc with all of the drivers working together seamlessly as if they were one driver on a very long waveguide. This innovative technology provides unprecedented output coherence and stunning, clear high-frequency sound quality regardless of the configuration.
Amplitude Shading Covering a venue with a smooth, consistent sound field is key to the success of any professional sound reinforcement project. The VRX accomplishes this with JBL's Array Configuration Selector, a convenient series 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 deliver more output for reaching a distant balcony while the lower enclosures can be ‘shaded back" with less output for the front rows of the venue. Each section of the venue can be fine tuned for a balanced, seamless overall coverage pattern.
Suspension and Rigging Ease of set up and takedown is critical to ensuring high quality sound reinforcement that meets both time and cost restrictions. JBL's exclusive integral rigging hardware for the VRX932LA allows the enclosures to be quickly and securely locked to one another by simply swinging a hinged bar into place and securing it with the included quick release pins. The optional VRX-AF array frame attaches to the rigging hardware of each enclosure providing an easy to use, elegant suspension system for flown arrays. A second array frame may be installed at the bottom of an array for applications where the system must be aimed down sharply.
Dual Angle Pole Socket JBL's dual angle pole sockets allow great flexibility in aiming the enclosure. By selecting the socket that best directs the sound towards the listeners, unwanted acoustic reflections are reduced and overall system performance is improved.
Differential Drive Woofers Sound reinforcement professionals constantly ask for more power but less weight so JBL designed the VRX's drivers with much less weight than comparable drivers and yet significantly increased its power handling and output. Super lightweight neodymium magnets positioned inside the voice coil of each driver, a key feature of JBL's patented Differential Drive woofer design, reduce the massive steel top plates, back plates and pole pieces found in the 'magnetic circuits' of conventional loudspeakers. The VRX's dual voice coil design delivers greater power handling while maximizing the performance of each driver. An integrated heat sink ensures excellent heat dissipation and consistent, reliable performance. Overall, the VRX weighs less, has more power capacity, lower distortion and lower power compression than any comparable system.
Single Cabinet When configured for smaller venues, or musicians working alone, the compact size, portability, light weight and stunning performance of the VRX allow it to be used as a single cabinet two-way utility speaker system that can be conveniently mounted on a tripod.
Pole Mount To create a small, compact non-flying system, the VRX may be mounted on a tripod. For greater power and low-frequency extension, one or two VRXs may be pole-mounted over a subwoofer, such as JBL's SRX718S or VRX918S.
Ground Stack For reaching bleacher and stadium seating from ground level, the VRX's ingenious cabinet design allows it be ground stacked in configurations of up to 4 enclosures delivering all of the power, clarity and control of a full flown line array system without the additional labor and expense.
Fly your VRX900 Array VRX932LA line arrays and VRX918S subwoofers may be suspended using the VRX-AF array frame. For fixed installations, 10mm forged eyebolts may also be used.
