JBL VRX918S PDF

In large venues, the very narrow vertical coverage of a VerTec line array enclosure allows a lot of acoustical energy to be projected to distant listeners. But in smaller venues, the narrow vertical dispersion means a large number of VerTec enclosures will be required to provide the needed vertical coverage. The VRXLA is designed with wider vertical coverage 15 degrees , so fewer speakers are required in small- to moderate-sized venues. As additional enclosures are added to the line array, the continuous arc is extended with all of the drivers working together as if they were one.

October 31, Part Number: Read these instructions. Three high-frequency drivers are mounted to the Constant Curvature waveguide which is designed so that multiple enclosures may be arrayed with no discontinuity in the vertical coverage pattern. As a result, the array will behave in much the same way as would a single loudspeaker. Speak er M i d Long In larger arrays, a single amplifier channel may be used for two adjacent loudspeakers. Array shading is then accomplished by adjusting the gain of the HF amplifier channels.

For extremely precise control over system performance, it may also be desirable to dedicate an individual system controller output to each HF amplifier channel. For most applications, the forward socket of the dual angle pole socket will be used.
