Firehouse Productions Scores Big at 2014 NFL Kickoff Event
Having designed and managed sound reinforcement systems for various major rock tours and high-profile live broadcasts, Firehouse Productions was well equipped to handle the event. “This was a good, straightforward show for us because we knew we were only going to be dealing with just two performers,” said Mark Dittmar, VP of Design and Engineering, Firehouse Productions.
Taking place just outside the CenturyLink Field stadium, Dittmar and his team were challenged with city restrictions on decibel levels, as well as the customary Seattle rain. To stay within the city’s stringent limitations on sound levels, the team relied on JBL VTX line arrays as well as several delay towers with JBL VERTEC® loudspeakers to manage the sound coverage within the outdoor space.
The stage’s main hang featured 14 JBL VTX V25 line array elements while 12 VERTEC VT4889 loudspeakers were deployed for side hangs on either side of the stage. Firehouse also utilized two clusters of six VT4889 for rear-fill and 12 VT4889 loudspeakers for the delay towers. The system also consisted of 16 VTX G28 and 20 VT4880A subwoofers and was powered by 90 Crown I-Tech 12000HD amplifiers. In addition, the system was monitored and controlled with JBL’s HiQnet Performance Manager™ software.
“The VTX line arrays are very capable and deliver a ton of power,” said Dittmar. “I don’t have to hang as many to get the same SPL when compared to hanging other rigs. Additionally, the reduced weight adds to the flexibility of design, and makes my job a lot easier when trying to integrate the system in a challenging space. In addition, the quality of the sound, especially the high-end, is absolutely amazing.”
"We've been using Crown since the beginning," said Dittmar. "They give us so much power in such a small package. One of our favorite aspects about Crown is the ability to build a custom library of presets that enable us to control any speaker in our inventory with the proper power and optimize their EQ, delay and other parameters.”
