Rock in Rio, Brazil

The Challenge:

The Rock in Rio festival regularly draws approximately 600,000 fans over seven days and features music from stars like Beyonce, Justin Timberlake and Bruce Springsteen. The festival needed a custom audio system that would provide great sound the audience could hear over the massive cheering of the crowds.

The Solution:

Working with Brazil-based Gabisom Audio Equipment, a longtime HARMAN JBL customer, the team designed and installed a HARMAN audio system with JBL VTX line arrays powered by Crown I-Tech HD amplifiers, marking the first time Rock in Rio used VTX and I-Tech HD.

Gabisom deployed a huge live PA system, featuring the JBL VTX V25 series as well as VTX S28 and G28 subwoofers. The system was powered by Crown I-Tech 12000 HD amplifiers and managed with JBL HiQnet Performance Manager software.

The Impact:

“We saw this year as an opportunity to capitalize on the increased power and controllability of the VTX line arrays with Crown I-Tech HD amplifiers. The system performed exceptionally, and we are confident that our HARMAN products will continue to accommodate the needs of the audience and performers as Rock in Rio continues to grow each year.” – Peter Racy, Chief Engineer, Gabisom
