Caracas, Venezuela (July 28, 2006)–Corporacion Dynaco C.A., a Venezuelan rental sound company, served a 55,000-person audience on July 5 as the Latin American nation celebrated its Independence Day. Commemorating the country’s liberation from Spain in 1881, major public events in Caracas included a 7-mile long military parade. This represented a significant sound reinforcement challenge to Dynaco, which the company met by deploying a system based on powered JBL VerTec DP Series line array elements for key audience listening zones.
The Venezuelan military keeps an eye on Corporacion Dynaco C.A.’s JBL VerTec rig used for the country’s Independence Day parade.”We selected JBL’s powered VT4888DP line array systems for this event for many reasons,” explained Guillermo Sanchez, Corporacion Dynaco’s manager and chief engineer. “We designed a huge distributed system to serve the long parade route, which had audience listening areas 300 meters (1,000 feet) deep, or more. The VerTec DP system with its self-powered enclosures made the setup incredibly easy, compared to what we have experienced in the past in the same situation.”
The Venezuela Independence Day event program featured a 150-person orchestra, 200-person chorus and martial band. A total of 38 sound towers were positioned, with 12 speaker positions nearest to the presidential review area each supporting an array of three VT4888DPAN powered line array elements. JBL VT4888 midsize and VT4887 compact line arrays systems were also incorporated into the sound system design. In all, 72 JBL VerTec units with additional supporting loudspeakers were used.
Additional supporting JBL loudspeakers were powered with Crown I-Tech 4000 and MA-5000VZ amplifiers. Signal processing included BSS FDS 366T and 334T system controllers. BSS 966 and dbx 1066 and 1074 units were in line for equalization and limiting. Soundcraft MH3-48 and MH2-40 consoles were provided for front-of-house and stage monitor mixing facilities, with JBL SRX712M stage monitors available in the performance area.
