Array sound column is a special type of speaker system that enhances the directionality and coverage of sound by linearly arranging multiple speaker units. Array sound columns are typically composed of multiple speaker units (such as full range speakers, tweeters, subwoofers, etc.) arranged vertically at certain intervals and angles to form a cohesive structure. Its working principle is to form a narrow beam by linearly arranging speaker units, achieving long-distance energy superposition radiation, thereby reducing the attenuation and distortion of sound during propagation. The coverage range of the array sound column is wide, suitable for large-scale performances, conferences, exhibitions, and sports venues.

Digital power amplifiers are composed of digital integrated chips and peripheral auxiliary circuits, which have the characteristics of low distortion, low noise, and large dynamic range. Its working principle is that the power amplification stage is completely in a switching state, amplifying digital signals of 0 and 1. The advantages of digital power amplifiers include small size, low heat generation, high efficiency, and low cost.
