1. Introduction:
This document describes the methods to be employed when installing and connecting
equipment associated with the Messenger XL digital controlled loudspeaker array, produced
by Ateïs International S.A.
This type of loudspeaker Array is equipped with onboard amplifiers, powersupply and signal
processing boards and needs extra precaution during installation and set-up of the unit.
The Messenger comes pre-programmed from the factory and is ready for immediate use. With
the concept of the Messenger we have focussed on an easy to install and to set-up unit which
does not lead to human errors and mistakes during the installation and set-up.
The Messenger can be programmed to adapt it for special applications where a different lobe-
shape is required. For that purpose you will need a USB-RS485 interface and the M-Control
communication protocol for Windows

2. General information:
The Messenger XL has the unique quality that the acoustical centre can be moved over the
array to match with required mounting heights. This can be achieved because each driver is
separately powered and processed and therefore all variations between a Symmetrical and an
asymmetrical arrangement can be made by a simple push on a button. This separates the
Messenger XL from any other line-array speaker making it the most flexible and unique line
array with software controlled directivity pattern.
Lobes:
The Symmetrical lobe has its acoustical-centre centred in the middle of the array. The
Asymmetrical lobe has its acoustical-centre centred at the bottom or at the top of the array.
Any other position of the acoustical-centre between the middle and the bottom/top of the array
fades the lobe-shape from a purely symmetrical shape to an asymmetrical shape.
Symmetrical lobes are mostly used to address balcony areas or is used for mounting heights
of 1.2m from the floor. It results in a sharply defined directive shape with vertical opening-
angles adjustable in steps from 40 down to 5 degrees. The lobe shape guarantees an equal
coverage even when seated very near to the source.
An asymmetrical lobe are used for typical mounting heights between 1.8 and 4m from the floor
and covers the groundsection. It results in a lobe that starts at 5m distance from the array at
ear-level and ends in a sharp lobe at 40m and further.(This depends on the type of array) The
Asymmetrical lobe has the ability to keep the sound deviation within 2 dB from 5 to 60m. Its
mounting height is NOT critical and therefore it is the most used system solution. The vertical-
opening angle can be adjusted in steps from 40 down to 5 degrees.
