“In large halls and arenas, line array systems can helpachieve even front-to-back SPLs and frequency response. Here's a tipfor smoothing level and tonality when using ‘old-school’systems; i.e., horizontally arrayed columns of speakers. Assuming thesystem can be divided [electronically] into a top [long-throw] andbottom [nearfill] cluster, start your tuning process by balancing andEQ'ing only the top section along with the sub-bass and get that rightat the back of the hall. Once that's done, blend in the lower sectionof speakers [usually at a lower volume and smoother EQ] to make up forwhat's missing up front.”
