NORTHRIDGE, CALIFORNIA, March 7, 2008 — Demonstrating the ease of rigging and superior coverage of JBL VERTEC® line arrays, live sound and lighting production company On Cue Systems of Phoenix, AZ recently provided the sound reinforcement system for a Barack Obama presidential campaign rally at Phoenix Veterans Memorial Stadium in Arizona. The “Stand For Change� rally drew more than 13,000 supporters and included appearances by Arizona Governor Janet Napolitano and Caroline Kennedy.

On Cue Systems deployed a VERTEC line array system consisting of a left/right arrangement of 12 VT4889 full-size line array elements per side, with 10 VT4880 full-size arrayable subwoofers per side. Additionally, On Cue Systems set up six VT4889 line array elements each for two outfill side hangs.

According to Dan Myers, System Technician for On Cue Systems, the event drew larger crowds than expected. “The campaign staff was only expecting five or six thousand people to show up, so it was amazing to see twice that many in attendance,� he reported.

Nevertheless, the audio system provided premium fidelity, adequate coverage and plenty of power. “The temporary rally stage where Senator Obama spoke was situated about 30 feet out in front of the existing main stage where the PA was hung,� Myers said. “However, I was still able to get enough level and gain-before-feedback from the system even though the stage was so far out in front, and even during times when his supporters cheered loudly. You could still hear his words over the exuberant noise of the crowd.�

In addition to the performance of the VERTEC line arrays, Myers noted, the loudspeakers’ light weight and simple easy to use suspension system facilitated a quick system setup. “The VERTEC system is extremely easy to rig and hang, and we used JBL’s VERTEC Line Array Calculator to determine the exact system configuration and splay angles,� Myers said.

Due to their suitability for use at high-profile televised events in large multi-purpose venues, JBL VERTEC VT4889 arrays have also been specified for use at both the upcoming 2008 Democratic and Republican National Conventions.
