AB  - Design, installation, and equalization of a complex rental sound reinforcement system for the Billy Graham Crusade 71 in Chicago's McCormick Place are described. Uniformity of coverage parameters in the cavernous 720- by 421- by 65-ft exhibition hall led to the decision to install a multicluster delayed loudspeaker system. The complete system, employing thirty-four loudspeakers, ten microphones, and eight power amplifiers had to be installed in forty-eight hours.
