PRESET
��he SW18����A has three factory presets already
stored inside the CO��� DSP, these preset are ready
to use the sub in combination with AX8����A vertical
array loudspeaker or any other professional audio
system:
STANDARD PRESET:
the response starts at �5H�� and
the cutoff is at 1����H�� with L� 2�dB��oct., use this
preset for almost any application at ground stack.
INFRASUB PRESET:
the response starts at 3��H��
and the cutoff is at ���H�� with L� 2�dB��oct., use
this preset when a very deep bass response is
required, it must be used at ground stack only, alone
or in combination with some other boxes set as
S��A�DA�D, absolutely do not use it in combination
of CA�DIOD preset. �O����: I�F�A and S��A�DA�D
P���S���� must �O�� be used together in close units.
CARDIOD PRESET:
the response of this preset is
the same of S��A�DA�D preset but when combined
together as described further the sub stack is capable
to cancel the bass in the backwards, absolutely it
must be used in combination of other two boxes and
at ground stack.
PREDICTION: EASE Focus 3
��o aim correctly a complete system we suggests to use always the Aiming Software - ��AS��
Focus 3:
��he ��AS�� Focus 3 Aiming Software is a 3D Acoustic Modelling Software that serves for the
configuration and modelling of Line Arrays and conventional speakers close to reality. It only
considers the direct field, created by the complex addition of the sound contributions of the
individual loudspeakers or array components.
��he design of ��AS�� Focus is targeted at the end user. It allows the easy and quick prediction
of the array performance in a given venue. ��he scientific base of ��AS�� Focus stems from
��AS��, the professional electro- and room acoustic simulation software developed by AFMG
��echnologies GmbH. It is based on the ��AS�� GLL loudspeaker data file required for its use:
AXIOM_SW1800_v1_0.GLL
, please note that the version must be 1.�� or more. ��he GLL file
contains the data that defines the Line Array with regard to its possible configurations as well
as to its geometrical and acoustical properties.
Download the EASE Focus 3 app from the AXIOM website at http://www.axiomproaudio.com/ clicking on downloads section of the product.
Use the menu option
Edit / Import System Definition File
to import the file
AXIOM_SW1800_v1_0.GLL
.GLL
from the installation Data folder, the
detailed instructions to use the program are located in the menu option
Help / User’s Guide
.
Note: Some windows system can require the
.NET Framework 4
that can be download from microsoft website at http://www.microsoft.com/en-

WARNING! CAREFULLY READ THE FOLLOWING INSTRUCTIONS AND CONDITION OF USE:
•
SW1800A is NOT designed to be suspended
, use it in ground stack only.
• ��his loudspeaker is designed exclusively for Professional audio applications. ��he product must be installed by qualified personal only.
• Proel do not accept any liability for damage caused to third parties due to improper installation, lack of maintenance, tampering or
improper use of this product, including disregard of acceptable and applicable safety standards.
CARDIOID SET UP
��he cardioid preset must be used in a sub array of three SW18����A. ��wo box must be oriented towards the audience and one must be turned in
the opposite direction (typically the box in the centre of the array). ��he bottom and the top boxes must have the S��A�DA�D P���S����, the box in
the middle must have the CA�DIOID P���S����. ��he audio signal sent to all boxes is the same.
��he CA�DIOID P���S���� has the same response of the S��A�DA�D P���S����, but to obtain the maximum cancellation on the back side of the array it
has the phase inverted and a proper level and delay setting.
��he following figures show two typical displacement of the array. ��he first with all the boxes in hori��ontal position for a total height of 171�� mm
and a width of ���� mm. ��he second one with all the boxes in vertical position for a total height of ���� mm and a width of 171�� mm.
NOTES:
When placing the cardioid array keep a distance to walls or other obstacles of at least 80 cm (2.6 ft) in order not to affect the radiation of the
reversed cabinet.
When placing multiple vertical cardioid arrays keep a distance between them of at least 110 cm (3.6 ft) in order not to maximize the combined
radiation of whole arrays.
When placing multiple horizontal cardioid arrays keep a distance between them of at least 80 cm (2.6 ft) in order not to maximize the combined
radiation of whole arrays.
