ZZ Top played through a D.A.S. Audio PA system at this year's Orange Bowl halftime show. Miami, FL (February 13, 2008)-- ZZ Top was the halftime act at this year's Orange Bowl, where the perennially sharp dressed men rocked through a D.A.S. Audio PA supplied by Interface Sound.
Based in Miami, Interface Sound is spearheaded by owner/operator Ralph Alvarez. For this year's Orange Bowl halftime show, Interface Sound constructed an audio system consisting of 60 D.A.S. Audio Aero 38A powered, 3-way line arrays and 12 Aero 182A 2k powered subwoofers that surrounded the playing field and faced out toward the stands.
"From the moment the whistle blew signaling halftime, we had exactly three minutes to get everything into position.," said Alvarez. "This included two 32 x 16-foot stage platforms, which were on casters, as well as the dozen custom-made carts for the loudspeakers. Like last year's show, we had 200 volunteers helping us with this task."
The actual sound reinforcement system on the field consisted of twelve mobile carts that were pulled into place at halftime by a dozen golf carts. Each cart consisted of five Aero 38A line array elements and one 182A 2K subwoofer. There were four carts on each side of the playing field, along with two carts at each of the end zones. Connections were accomplished by two cables between carts (one each for subs and highs) plus a single phase, 60-amp Hubbell connector plate. To maintain signal strength and integrity, twenty-four channels of RDL line amplification were placed into service.
"This configuration worked really well for us in the past, so it made sense to repeat it again this year," notes Alvarez. "We were able to reach all the way up into Level 400-known to the audio crew as the 'nosebleed' section. Using D.A.S. Audio's version of EASE Focus, we configured our system's coverage quite easily and it all worked out exceptionally well. Frank Martinez, our company's Chief Engineer, handled all programming and signal routing for the project."
FOH (front of house) responsibilities were handled by Danny Fernandez. For this event, a Yamaha PM5D digital mixing console was deployed for redundancy while two Digidesign Venue consoles were used to mix FOH and monitors. Mixing live to the FOX TV feed was Joel Someillan.
