The line array concept has been around since the late 1950s, though for more than 35 years, the systems were column arrays, primarily for vocal reproduction in installed systems. It wasn’t until the mid 1990s that line array systems were developed for large-scale, full-range, high-performance touring loudspeaker systems. Now, they’re commonplace in touring, as well as installations, and the systems come in all shapes and sizes for a multitude of applications. We’ll be looking at a mixed bag of implementations representative of the diversity of available products. As such, there will be examples of column arrays as well as modular systems.
