LONDON, United Kingdom – At PLASA 2012, HARMAN’s JBL Professional is introducing the VTX-LZ-K Laser Accessory Kit, which facilitates the alignment of JBL VTX Series line array loudspeakers for optimum performance and audience coverage.

The VTX-LZ-K includes two VTX-LZ laser units and one rechargeable VTX-LZ-PS power supply. The VTX-LZ employs a Class 3R green laser (less than 5 mW, 532 nm wavelength) and is approximately 20 times more visible than a red laser for maximum visibility over long distances indoors or outdoors. The VTX-LZ laser units connect to the VTX-LZ-PS power supply by means of a standard XLR cable and multiple lasers can be daisy-chained (up to 10 units powered from a single power supply).

All VTX-LZ-K components feature rugged aluminum and high-impact plastic weather-resistant construction for long-term durability. The laser units are factory-calibrated, weather-resistant and feature fan-cooling and on/off cycling for extended laser life.

VTX-LZ laser units attach to the VTX enclosure suspension frame and are secured using a quick-release locking pin. Lasers can be mounted on either side of the enclosure by changing the orientation of the VTX-LZ mount tab and since the laser is centered on the middle of the enclosure, it provides an accurate site angle reference in accordance with JBL Line Array Calculator II (LAC II) software predictions.

“Precise VTX V25 line array vertical pattern control requires precise focus to achieve optimum coverage and the VTX-LZ-K Laser Accessory Kit is a valuable time-saver that helps to ensure the best possible setup of a JBL VTX line array system,” said Paul Bauman, Senior Manager, Tour Sound for JBL Professional. “Multiple VTX-LZ lasers can also be used to assist with microphone placement for more detailed system measurement as part of the calibration and tuning process and this has been specifically designed into the workflow of recently-released JBL HiQnet Performance Manager™ software.”

When mounted on the top enclosure of a VTX line array, the VTX-LZ laser provides a visual reference to confirm the on-axis vertical site angle of the array while also providing an azimuth indication so that relative horizontal pan angles can be matched for FOH left-right arrays. With reference to LAC II software, the normal installation procedure is to attach a tape measure to the lower front corner of the bottom VTX enclosure as a reference for setting array trim height. Once the array trim height is set, the front motor is turned off, the VTX-LZ is turned on and the rear motor is manipulated to adjust the array site angle while visually referring to the laser to ensure that top enclosure is pointed at the rear of the desired audience location.

For advanced system tuning, multiple LZ lasers can be deployed to serve as site angle references for individual array circuits, assisting in physical measurement microphone placement to correspond with virtual measurement microphones shown in LAC.

Using JBL HiQnet Performance Manager™ control software and with reference to measured spatial response, circuit level gain shading and JBL Line Array Control Panel (LACP)  frequency tapering adjustments are performed as a first step in system tuning. This initial step is referred to as array calibration and JBL LAC II / LACP simulations provide a good starting point. For the actual real world installation, VTX-LZ lasers mounted on array circuits can be used as a reference for microphone placement to verify and further refine the starting point gain shading and tapering parameters that were pre-determined in JBL LAC II / LACP and Performance Manager.

Once SPL and frequency response has been optimized on a circuit level, global equalization can then be applied to the entire array to compensate for room-related effects. For this step, array equalization can be based on the spatial average of all measurement microphones that were placed throughout the audience area with reference to VTX-LZ laser aiming locations. This patented approach to system measurement and tuning has been specifically designed into the workflow of Performance Manager (US patent 2008/0170729).

NORTHRIDGE, California – Continuing its commitment to staying on the cutting edge of technological advancement, Maryland Sound International recently became the first company in the United States to add the new HARMAN JBL VTX Line Array Series loudspeakers to its inventory. One of the world’s leading sound production companies, Maryland Sound was founded in 1966 to serve Frankie Valli and The Four Seasons on a national tour, growing over the decades to become one of the industry’s foremost sound contractors, with a resumé spanning presidential inaugurations to Times Square New Year’s Eve broadcasts to major concert tours.

Maryland Sound first deployed its VTX system at the annual White House Easter Egg Roll on April 9. “We built our business on offering our clients the very best, and we are purchasing more than 300 of the new JBL VTX V25 line array loudspeakers,” said Bob Goldstein, President of Maryland Sound. “We will be using them for large-scale events, smaller productions and everything in between.”

The JBL VTX Series is the next generation of JBL line array loudspeaker design. “VTX represents an evolution of JBL’s industry-standard VERTEC® that heralds a new era in performance, system integration and user-friendliness,” said Paul Bauman, Senior Manager, Tour Sound, JBL Professional. “The VTX Series features JBL’s legendary sound quality coupled with the most advanced sound reinforcement technology and support available.”

“When you start with outstanding components and put them into a well-designed enclosure, you can’t help but end up with outstanding results,” Goldstein continued. “I have to say that the technology behind the V25 is amazing. I’m a guy who likes to experience high-frequency reproduction all the way out to 20kHz. The D2 drivers handle a ton of power with no breakup modes and no measurable distortion. Having the D2 drivers in the V25 makes a huge difference and I wanted to have that kind of sound quality in our inventory.”

The JBL VTX Series V25 full-size, 3-way high-directivity line array element features two 2,000W, 15-inch Differential Drive® woofers mounted in die-cast aluminum baffles, with four 8-inch Differential Drive midrange transducers and three D2 dual-diaphragm dual-voice-coil compression drivers mounted on a third-generation waveguide and patented Radiation Boundary Integrator assembly.

“The new JBL D2 high-frequency driver is fantastic,” Goldstein added. “There is virtually no distortion, and designer Paul Bauman and his team came up with a new waveguide that takes full advantage of its performance to distribute extremely smooth frequency response with even coverage.”

In addition, Maryland Sound will continue to use its existing VERTEC VT4889 inventory. “I think the VT4889’s with the V5 software tunings are world-class and we will not stop using them anytime soon,” Goldstein noted. “That said, the VTX V25 is simply a step up in its ability to resolve musical detail.”

“Our clients want to know that we’re always on the leading edge of the technological state of the art,” Goldstein concluded. “Having the best technology like the JBL VTX V25 means we can provide the best service AND the best sound. Our clients don’t have to ask us to upgrade—we do it on our own because we want to stay on the cutting edge.”
