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.

StepArray+ 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. StepArray+ combines the features of Dante™ and StepArray to achieve

ever higher levels of efﬁciency and ﬂexibility.

The StepArray+ range includes 6 models of column speakers, from 1.50m to 4.50m high.

5.4 Using the StepArray+ software

The StepArray+ control software does not include Dante routing functionality.

When using Dante to transmit audio, you will need the Dante Controller software to assign Dante channels

to StepArray+ columns. Dante Controller is available free of charge from the Audinate website: https:

//www.audinate.com/products/software/dante-controller.

When launching the StepArray+ control software, the ﬁrst screen lists all the StepArray+ columns it can ﬁnd on the

network. The ﬁrst connection to a StepArray+ column can take up to 1 minute: this is the time needed to initiate the

communication.

Figure 1 – StepArray+ control software: main screen.

A click on a StepArray+ box leads to the settings screen of that speciﬁc column. All the parameters of the column

can be changed within that screen.
