At Harbor Park in Norfolk, Virginia, home to Minor League Baseballâ€™s Norfolk Tides, a new JBL VLA line array system gave the teamâ€™s stadium a sonic refresher that both vastly improved the sound on the field and did so very cost-effectively. Two clusters, each containing six JBL VLA 901 speakers with 90-degree horizontal horn coverage patterns offer fans exceptional sound and high intelligibility while staying within both the teamâ€™s budget and the physical limitations of the park.
â€œIt was challenging because we could only work within the space that was already there,â€? said Tom â€œTâ€? Brockenbrough, Project Manager for Onyx AudioVisual, the systems integrator for the project. Due to budget constraints, the system design and installation teams replacing the PA system were required to use the same sofitted set-backs in the outfield wall of Harbor Park, which was completed in 1993. Furthermore, the soffits could not be accessed
from above, eliminating the possibility of using a crane to lift PA components in; they would have to be loaded from the side. â€œTime and budget pressures meant we couldnâ€™t run conduit and install a distributed audio system, which would have been the ideal situation,â€? Brockenbrough said.
Gary T. White, Senior Associate at acoustical consultant firm Wrightson, Johnson, Haddon & Williams (WJHW), concurred. â€œBudget and time frame were major considerations. We started discussing the replacement late in the 2009 season. The desire to have a new system in time for the 2010 season was probably the most important factor in system choice, with cost a close second. Even with a proper budget, our estimates couldnâ€™t rationalize designing and installing a distributed system in less than eight months.â€?
However, White had an inspiration: â€œI had done a lot of other minor league and major league stadiums and really wanted to try a line array for an outfield cluster,â€? he said. â€œWJHW had used VLA line arrays other projects and I was working on some football stadiums with end-zone clusters, so the VLAâ€™s for Harbor Park were an easy choice.â€?
White specified the VLA 901 enclosure, part of the JBL VLA Series line arrays, which are based on the same advanced engineering used in JBLâ€™s VERTECÂ® Series line array systems. Designed specifically for permanent installation applications where even coverage, high intelligibility and very high sound-pressure levels are required, the VLA Series includes six large-format horn-loaded modules with three horizontal horn coverage patterns (30, 60 and 90 degrees) in both mid-power and high-power configurations. This modular horn-loaded concept incorporating JBLâ€™s Precision DirectivityÂ® series technology provides system designers additional flexibility to vary the horizontal pattern within a vertical array.
â€œGiven the constraints we had to work with, the JBL speakers were the best possible solution,â€? Brockenbrough said. â€œThey were installed in the same spaces as the old PA, but they brought so much more power to the stadiumâ€™s sound. We were testing them in place and theyâ€™re incredibly powerful, yet the sound was still highly articulate, with very even coverage and very good frequency response. There is no other box out there with that much output, that can throw that far, and still sound great.â€?
