Description

The VRX928LA is a lightweight (28 lb / 13 kg) compact 8" two-way linearray 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 such as JBL's VERTEC or VRX932LA.

The Constant Curvature waveguide mounts two compression drivers on a continuous arc. When additional VRX928LA speakers are added to the array the uninterrupted arc continues. In effect, all the drivers work together as if they were a single driver on a very long waveguide. Since there are two HF drivers in each VRX928LA, the combined power handling and acoustic output of the system is far greater than a single driver could achieve.

VRX928LA uses amplitude shading to shape the coverage of the array. Switches on the input plate allow, for example, the upper box in an array to reach the distant rear of a room while the lower box is shaded back to reduce excessive level at the front of the listening area.

One or two VRX928LAs may also be used on a tripod or over the VRX915S subwoofer. The integral rigging hardware is used to securely lock the array together.

As many as six VRX928LA speaker systems may be suspended in a single array for a nominal vertical coverage of up to 90. Suspended applications require the JBL VRX928LA-SMAF array frame (available separately). For applications in which the array must be aimed sharply down, a second Array Frame may be installed to the bottom of the array serving as a pull-back

Array Configuration Selector (ACS)

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 VRX928LAs, the lower speaker (which covers the nearest listeners) may have its high-frequency output reduced. At the same time, the upper speaker may have its high frequency output increased. The overall sound-power in the room is unchanged but the distribution of acoustic energy to the audience is far more uniform.

Amplitude shading of a VRX928LA array may be accomplished in passive or bi-amplified systems. In passive mode, the Array Configuration Selector may be used. The -3 dB position will typically be used for the speaker(s) in an array that are covering the nearest listening area. The +3 dB position will be used for the speaker(s) covering the more distant areas, or to compensate for the low-frequency build-up resulting from mutual coupling of multiple woofers in an array. In bi-amp mode the amplifier output needs to be adjusted accordingly.

    I’ve used this set up 4 times now for small to mid sized venues . ( under 500 people )
    About me : I’m a very small sound company in St. Louis specializing in Club , Band
    and Festival sound reinforcement. I always have to work on somewhat of a tight budget. I have to make every buck count. I’m writing this to maybe help other small sound companies or musicians working on tight budgets.
    For me and my budget this was a sizable investment for a small system . So I took the risk since there are almost no reviews on this equipment.
    My goal was to find a high quality light weight portable system that was easy for one person to set up. The system would be used in a ground stack configuration not flown. Easy in - easy out. Preferably fit in a small van to save gas on the big box truck.
    EQUIPMENT - 4 - VRX928la tops 4 - VRX915s Subs 2- JBL bk-4 poles
    4 - QSC plx 3402 amps ( 2 for tops Bi-amped and 2 for subs.) DBX drive rack , DBX 266 compressor Ashly E.Q. Allen & Heath or Midas mixing Board. Yes it all fit in my Astro van ( yea ) Note ; I have also run QSC plx 1804s on top.
    END RESULT - Full crystal clear sound that fills entire room evenly , tons of punch . Pretty much everything I was hoping for. The top are robust and bottoms are very solid.
    Average room size 80 X 125 ft. 105 spl
    Each venue so far has required softer volumes of play back pre-show. You hear every tap of the ride cymbal from the front all the way back at the rear at a very low volume.
    NOTES; out of the box I ran tops in passive mode ,way too much horn , tons of e.qing required did not care for the overall sound. But in bi-amp mode with drive rack set to JBL spec,s they will rock you .
    I decided on the 928 instead of the 923 mostly because of the weight 2 of the 932’s on a pole is over 80 lbs.
    My system design was to be kept small , light weight indoor work. I wasn’t looking for something to replace my typical outdoor setup of 4 to 6 sr4733 tops and 8- 4719 subs. I will be using this system this weekend outdoors for the first time under a tent in a smaller VIP section preempting the main stage act with my larger system. I have all the confidence in the world they will sound fantastic. Last note the JBL case covers for all of these are a must they protect very well ,after all if I would have loaded them in a road case I would have needed help unloading and my big truck to transport. enjoy ,Steve
