Five DP226 controllers were used at the FOH position to control the line arrays positioned on 18 carts ringing the field. These comprised the primary PA system for the pre-game and half-time entertainment. One of the DP226 units had a highly specialized task at Super Bowl XLI, though. Given the height of the sharply raked 74,000-seat stadium, wind could be expected to significantly alter the frequency balance by the time the sound reached the upper seats. ATK AudioTek’s technicians measured distances and wind velocities, determined the frequencies that would be most affected, and used the DP226 to create a filter that would boost those frequencies and route them, with appropriate delay timing, through the uppermost speakers in the stadium’s installed distributed sound system. “The DP226 has a lot of flexibility built in that allows us to do specialized tasks like this, and do them with a high degree of precision and certainty,” says Harmala. “XTA equipment is an important part to ATK’s success.”
