This chapter contains important information about precautions to be taken
about the suspension of a LSS line-array system.
Before proceeding with any operation for lifting thesystem , therefore
recommend that you read this chapter and follow thetips and warnings it
contains.The lifting of a line-array system must be made only by personnel
familiar with proper preparation,experience and knowledge of the applicable
safety standards.
The flow rates of suspension accessories provided by LSS are certified by a
qualified consultant external to the Company.
The original document is available at the LSS office.
You must regularly inspect the facility and , in case of doubt,immediately
replace all the material and all equipment used for the suspension.
This practice is essential to prevent damage to property and or person:no
way you can overlook this rule and proceed by accepting arisk.
We strongly recommend , therefore , to follow a regular program of checks
and inspections on all components , which must bedocumented by
inspection reports compiled by the staff that has installed the system.
In case of accident , local codes may require proofdocumentation of audit
reports and the corrective actionin place following the detection of defects .
In some countries ( including Italy ) rules on the maintenance oflifting
equipment ( hoists , ropes and chains ) requireperiodic checks and
inspections carried out by a company or byLicensed professionals .
It is absolutely not permissible to accept the risks with regard to safety of
public or staff!
When you suspend a system to support structures on the ceiling or roof,it
must be ensured with extreme care, by calculation or, in some cases,by
instrumental measurements, which do not exceed the maximum flow rate
of the structures themselves in order the installation is absolutely secure .
Do not installspeakers or entire systems to unsafe structures . If necessary,
consult licensed professional.
All suspension accessories NOT provided by LSS are under
theresponsibility of the user, that uses them at his own risk and peril.

adjusting the inclination.
BUMPER AND SYSTEM HANGING
Bumper can be fixed to the ceiling or other supports via holes for bumper
suspensionor the holes for suspension and regulation of inclination using
eyebolts and a chain or a rope able to support the weight of the entire
apparatus.

SB17__________________________________________________________________________________
16| Operating Manual ver. SB17-EN-1.0
Suspending the bumper from holes for suspension and regulation of
inclination, it is possible to determine the inclination of the entire system.
Inclination value depends from hole and speakers used because of varying
the number of speakers, change the center of gravity, so for an exact
operation use an inclinometer.
To pull back the system, connect an eyebolt to the rear speaker plates and a
rope or a chain, then manage the inclination.
ARRAY SIMULATOR SOFTWARE
The angle of tilt of the single speaker, as well as the inclination of the entire
system depends on the location of installation and the listening audience.
To know exactly these angles for optimal installation,equip with an
inclinometer and use the software ‘Array Simulator’* of LSS.
After inserting the information of the speakers system and installation
location, ‘Array Simulator’ software* allows to:
- Display of pointing and layer maps.
- Display the structure of the hanging system .
- Print complete reports.
- Display levels on the areas of listening.
- Calculation of the angle of inclination to thechosen point of suspension.
- Preset for the areas of listening and the setup of the array.
- Display Pressure Levels (SPL).

To use an array with ST17 and SB17 is necessary an
external digital processor with custom setup provided by
LSS. One output channel drive the SB17 and another one
drive the ST17. If your amplifier can manage a 2 Ohms Load
and has sufficient power, it is possible to connect a
maximum of 6 ST17 in parallel per channel (total impedance
will be 2 Ohms) or 4 SB17 in parallel per channel
Choose a safe mounting location, so as to prevent the
cables can be stepped on or create tripping hazards.
Before making connections between mixer and speakers,
make sure the mixer volume is turned down.
You can now use the system.
