A timeline of live-performance system design evolution over four decades will be highlighted. In addition to a historical review of control & monitoring processes, this presentation bridges the gap from control-only networks to network digital audio, noting migration paths to beam-steerable line array elements that are now described as network endpoint devices. Tutorial also presents various loudspeaker enclosure and multi-box array topologies in use over time, as a broad-spectrum overview of technical developments taking place since the AES 6th International Conference (Sound Reinforcement, Nashville, 1988) and the AES 13th International Conference (Computer-controlled sound systems, Dallas, 1994). Each of these landmark events included content that foreshadowed the development of today’s modern high-powered loudspeaker arrays that incorporate beam-steering technology. Recently-emerging trends will be examined, and potential future developments contemplated. Of potential interest to sound reinforcement technicians and system operators, installed-system designers, rental sound service company providers, and live-sound equipment product development engineers.
