1. Introduction
StepArray column speakers ensure perfect speech intelligibility and optimal
acoustic comfort, even in noisy and reverberant venues. They are based on
the DGRC (Digital & Geometric Radiation Control) principle patented by Active
Audio.
Compared with a classic sound system in which each loudspeaker is controlled
independently, the DGRC method makes it possible to decrease the number of
channels to be controlled, thereby enhancing economic efficiency.
The StepArray range includes 6 models of column speakers, from 1m to 4m
high.
