Seoul, South Korea (September 12, 2014)—Alpha Sound recently provided an Adamson Energia sound system for the AIA Real Life: NOW Festival held in Seoul, South Korea.
The two-day festival took place at the Jamsil Olympic Stadium with pop icon Lady Gaga as the headliner the second night . Other acts that performed during the festival included Psy, Miss Nine, Sidney Samson, Ivan Gough, Cazzette, twenty one pilots, Man With A Mission, Galaxy Express and Glen Check.
Both Sun Kim, technical support manager for Sound Solutions, Adamson’s South Korean distributor and David Dohrmann, technical director Asia-Pacific (Adamson), were on site to assist with system design, set-up and tuning of the Adamson PA.
For the AIA Real Life: NOW Festival, the Stadium was played sideways, ie. the stage was placed at the wide end of the stadium. Seating was on the field and also available in lower stadium tiers; seats that were located behind the stage were not used for the event.
Dohrmann worked closely with Sound Solutions to design a system utilizing Adamson’s Blueprint AV 3D modeling software.
“The stadium layout required a throw of 120 meters distance and 7 meters elevation to cover all of the seating areas,” explains Kim. “The goal was to achieve roughly 105 dBA average SPL with a dynamic live music program throughout the listening spectrum without any gain reduction from the system limiters.”
In order to accomplish this, left-right arrays—each made up of 18 E15 and 6 E12 enclosures—were hung from scaffolding columns constructed on each side of the stage.
Low end was covered with two hanging columns of 12 Adamson E218 subwoofers flanking the E15/E12 arrays. In addition, 10 Adamson T21 subs were ground stacked beneath each E15 array with eight E219 subs deployed to deliver the pounding beat the music demands.
To complete the system, two additional line arrays—this time comprised of 16 Adamson Y18 enclosures—were added to handle out fill duties.
The entire system was driven by racks of Lab.gruppen PLM amplifiers with Lake Processing. The main line arrays were powered by 16 PLM 20000Q amplifiers, another 12 PLM 20000Q drove both the flown E218s (6 per amp), the ground E219s (4 per amp) and some of the T21 subwoofers (2 per amp).
