JBL VRX932LA-1 12" Array Speaker

The VRX932LA-1 is a light-weight (46 lb / 21 kg) compact 12" two-way line array speaker system designed for use in arrays of up to six units. VRX932LA-1 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 JBLs VERTEC.

The Constant Curvature waveguide mounts three compression drivers on a continuous arc. When additional VRX932LA-1 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 three drivers in each VRX932LA-1, the combined power handling and acoustic output of the system is far greater than a single driver could achieve.

VRX932LA-1 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 a distant balcony while the lower HF section is shaded back to reduce excessive level at the front of the listening area.

One or two VRX932LA-1s may also be used on a tripod or over subwoofers. The integral rigging hardware is used to securely lock the array together while the dual-angle pole socket provides aiming flexibility.

As many as six VRX932LA-1 speaker systems may be suspended in a single array for a nominal vertical coverage of up to 90 . Suspended applications require the JBL VRX-AF 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.

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-1s, 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 VRX932LA-1 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.
