Firehouse Productions Finds the Pulse at 2013 iHeartRadio Music Festival with HARMAN’s JBL Professional VTX Line Arrays and Crown I-Tech HD Amplifiers

LAS VEGAS, Nevada – For the third year in a row, Firehouse Productions turned to JBL Professional and Crown Audio for the sound reinforcement system at the iHeartRadio Music Festival, deploying JBL VTX line arrays powered by Crown I-Tech HD amplifiers. The 2013 iHeartRadio Music Festival was held at the MGM Grand Garden Arena in Las Vegas and featured performances by Paul McCartney, Justin Timberlake, Katy Perry, Bruno Mars, Muse and more.

This year’s system featured a total of 36 JBL VTX V25 fullsize line array elements (18 per side) and 24 VERTEC® VT4889 fullsize line array elements (12 per side), with 15 VTX G28 ground-stacked subwoofers. In addition, 12 VT4886 subcompact line array elements provided front fill. Crown I-Tech 12000HD amplifiers powered the system, which was controlled via JBL HiQnet Performance Manager™ software.

The 2013 iHeartRadio Music Festival marks the latest in a series of high-profile events in which Firehouse Productions has utilized JBL VTX line arrays and Crown I-Tech HD amplifiers, including the 2013 Global Citizen Festival, the 2013 Rock and Roll Hall of Fame Induction Ceremony and the MTV Video Music Awards.

“Throughout the summer, we have continued to rely on VTX and I-Tech HD for our largest productions and they have consistently provided reliable, top-notch audio quality for each event,” said Mark Dittmar, Lead Design and Integration Engineer at Firehouse Productions. “The controllability of the sound and the ease of setup make this combination our go-to option for any production, but particularly for the highest-profile events.”
