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. Critical distance parameters in the cavernous 720 ft x 421 ft x 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.
