Rock the Bells with D.A.S.

Aero Series2  line array delivers big at San Manuel Amphitheater


Since 2003, Guerilla Union's Rock the Bells tour has established itself as a world-class hip-hop platform. This year's tour was no different and included appearances by NAS and Damian Marley, Cypress Hill and Ice Cube, Busta Rhymes plus numerous equally compelling acts. The musical extravaganza made its Southern California appearance at the San Manuel Amphitheater in front of and an appreciative crowd of approximately 14,000.

Irwindale, CA-based DBS Sound & Lighting was contracted to provide sound reinforcement for the event. Ruben Silva, owner/operator of DBS Sound & Lighting, knows that the San Manuel Amphitheater can be a challenging environment for delivering high SPL sound. He discussed the issues that confronted him and his decision to deploy a D.A.S. Audio Aero 2 system.

"Providing coverage to the main seating areas in front of the stage is one thing," explained Silva, "but the grass lawn area further out is an entirely different matter, as the high winds can wreak havoc with the sound. In order to provide the long throw and broad horizontal coverage we needed, the system required serious power. Because of this, I was very concerned about rear projection, as it complicates on stage monitoring and the ability of the performers to hear clearly. This was a huge consideration and one of the key reasons we decided on D.A.S. Audio's Aero 50 line arrays."

DBS Sound & Lighting deployed a system consisting of twenty-four D.A.S. Audio Aero 50 line array enclosures-flown 12 per side. Low frequency support was partially provided by eight D.A.S. LX-218 high performance subwoofers-distributed evenly across the lower front of the stage. Power for both the Aero 50's and the LX-218 subwoofers was provided by external amps. DBS's proprietary subwoofers, stage monitors, and side fill enclosures completed the system.

Silva reports that the Aero 50's delivered in a big way. "The system did a terrific job," said Silva. "The Aero 50's have tremendous throw and provide very even coverage with a full, fat sound. The rigging hardware is very well designed and makes the process of assembling and flying the boxes remarkably easy for a system this large. Perhaps most significant is the fact that the Aero 50's are really well designed in terms of their ability to minimize rear projection. There was very little noise on stage-almost none to speak of."

Silva was equally complimentary of the D.A.S. LX218 subwoofers, "The LX-218's worked very well. In addition to their low end punch, they exhibit good detail, which frequently escapes competing sub bass enclosures. I only wish I had more."

With the Rock the Bells tour over, Silva reflected on the system's performance. "This Aero system delivered very impressive results," notes Silva. "Going into this project, we had some questions and, I have to say, the D.A.S. folks were extremely supportive and responsive. I received numerous compliments about the sound systems' performance-particularly from some of the key engineers that were mixing, including the FOH engineers for The Roots, House of Pain, and Damian Marley. It was very cool to see all the people enjoying the music and my client, Guerilla Union, was very pleased with the sound. When the artists and the client are happy, I'm happy."
