Velez and his crew also added delay loudspeakers to insure coverage reached all the way to the back of the area, flown from towers positioned roughly 165 feet from the main stage.
This portion of the setup included four DAS Aero 50, 3-way, large-format line array enclosures per side, driven by Lab.gruppen FP 9000 power amplifiers rack-mounted beneath the delay towers and which were accompanied by another three Aero 182 subwoofers per side.
Considerable Numbers
Velez utilized Lake processors to dial-in and optimize the main stage portion of the system, with a dbx DriveRack processor deployed for the delay system.
Four outputs of the DriveRack fostered a cardioid arrangement. Another DriveRack signals for TV and radio coverage of the event.
“Antonio Villamizar, our setup engineer, did an amazing job working with the system and the Dolby Lake processors to make the system fully functional for everyone,” says Velez. “The sound system exhibited deep bass, perfect mids for the vocals, and high frequencies reaching all areas. The coverage was excellent at all frequencies.”
Approximately 115 feet out from the stage, the front of house position was equipped with two Yamaha digital consoles primary mix engineer Federico Lopez: a PM5D and an MC7L. These consoles managed a large number of inputs – primarily microphones, both cabled and wireless. A third Yamaha board – another MC7L – was provided for monitor mixer Byron Ospina.
The microphone package included several models from the Shure Beta and SM Series lines. Mics from AKG (D 112, 414, and C451), Sennheiser (MD 421 and MD 441), Audio Technica (AT4033) and RØDE (NT5) were also available in considerable numbers, as were Shure wireless mic systems, including six PGX24/Beta 58 packages.
Up to 10 DAS Road 15A powered, 2-way stage monitors were deployed on stage as needed, bolstered by ground-stacked Aero 12A arrays for stage fill.
“All of the artists told us they were able to give a great show since they were comfortable with the stage sound,” Velez concludes. “The reaction from the crowds was equally gratifying. The hip-hop and electronic fans had all the bass they wanted. while the metal and punk fans heard all the distorted guitars without hurting their ears. The event was a huge success.”
