1 Introduction
St 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.
St also allows the use of existing network cables and helps to achieve significant savings in wiring, with up
to 64 channels on a single Ethernet cable. St combines the features of Dante™ and StepArray to achieve
ever higher levels of efficiency and flexibility.
The St range includes 6 models of column speakers, from 1.50m to 4.50m high.
