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
channelstobecontrolled,therebyenhancingeconomicefciency.
StepArray+ also allows the use of existing network cables and helps to achieve
signicantsavingsinwiring,withupto64channelsonasingleEthernetcable.
StepArray+ combines the features of DanteTM and StepArray to achieve ever
higherlevelsofefciencyandexibility.
The StepArray+ range includes 6 models of column speakers, from 1.50m to
4.50m high.

3. Assembling
1. Remove the back
plate of the amplifier
module.
2. Place the amplifier
module at the top of
the passive column.
3. Secure the amplifier
module using the
supplied M8 nut.
4. After wiring, close
the connection box by
mounting the back
plate.

5. StepArray+ control software
The StepArray+ control software is available for Windows and OSX operating
systems. Installers can be found on the supplied USB key or on Active Audio’s
website by following this link: http://www.activeaudio.fr/ downloads.
5.1. System requirements
Processor 1Ghz or better
Memory 512Mbyte of RAM
Network Standard wired Ethernet network interface (100Mbps or Gigabit).
Wireless LAN (Wi-Fi) Ethernet interfaces are not supported
Operating System Windows 7 SP1 or newer Mac OS X 10.7.5 or newer
5.2. Installation on Windows
Start the installer package by double-clicking on it, then follow the instructions.

5.4. Using the StepArray+ software
The StepArray+ control software gives access to the following functions:
• input selection: Dante or analog input
• general output volume
• steering parameters for directivity control
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+ co-
lumns.
Dante Controller is available free of charge from the
Audinate website: https://www.audinate.com/pro-
ducts/software/dante-controller.

6. Installation of the columns
StepArray+ columns are mounted vertically, usually on a wall, using the sup-
plied brackets. Figure 9 illustrates the steps to follow for column mounting. See
