When Paul McCartney took the stage in the center of Alltel Stadium for the Super Bowl halftime spectacular in Jacksonville, Fla. last month, he benefited from a P.A. system designed by provider ATK AudioTek, which incorporated the XTA DP226 speaker processing system for speaker control. Five XTA DP226 processors were used to control 18 carts loaded with JBL Vertec speaker systems, apportioned into quadrants covering the entire stadium. Additionally, XTA DP224 processors were used by the monitor system to control foldback to the stage.
ATK AudioTek fielded 42 employees to man two separate P.A. systems, for entertainment and for stadium announcements. Coming out of a Yamaha PM5D digital console at the FOH position manned by mixer Patrick Baltzell the signal remained digital through the QSC RAVE fiber system, distributed to four P.A. sectors covering the entire stadium. Once at the speaker carts, the XTA DP226 processors took over, providing speaker control, EQ, crossovers and delays.
