and dry ground. Please avoid operating the system next to a heat source. Protect the system from
strong wind to avoid possible collapse.

System can’t be placed near fire source. During storm, system should be unplugged. Atmospheric
discharge can lead to product damage. Cables should be placed in a way that protects it from being
cut or damaged in any other way.

PRODUCT DESCRIPTION

SLA 112 is a touring grade line array system based on BMS and Eighteen Sound transducers. Double 1” high frequency
tranducers with 12” woofer provides a safe output overhead for events up to medium size with demanding rock music.

SLA 112 rigging system was designed to provide safety for rigging up to 16 modules in a single array. All of the
measurements for acoustic prediction software has been performed in German Institute of Acoustics. For splay angle
calculation and coverage prediction please use EASE Focus 3 application. The libraries are also compatible with EASE
Focus 2 application.

In case of an event without requirement for high output at low frequencies SLA 112 can be used as a full range system
without additional subwoofer section. 12” woofer allows the system to be cut off as low as 50Hz. This way you can
save cargo space when providing sound reinforcement for specific kind of events.

OPERATION

Before you connect the product to other elements of the system, make sure all of the parameters
match and guaranty a safe operation.

After exposure to very low temperatures system should be left until the temperature is similar to the
operating conditions during the event. If the system is exposed to the temperature shock it can be
damaged.

Przed uruchomieniem systemu należy się upewnić, że wysyłany sygnał nie jest przesterowany.

HOW TO MINIMIZE RISK OF SYSTEM DAMAGE

Make sure the signal is not distorted and is within operating levels of the system. Avoid placing a
microphone in front of the system to minimize the risk of a feedback. Before you turn on the system make
sure the amplifier and loudspeaker system are properly matched with all of the technical data.

GLL LIBRARIES FOR EASE FOCUS 2 AND EASE FOCUS 3

For acoustic prediction use EASE Focus 2 or EASE Focus 3 with libraries provided by manufacturer. Be sure
to use correct model and correct version for simulations. To download system libraries, please visit
manufacturer website or contact the manufacturer.

VENUE SIMULATIONS

The more precise the model the accurate the simulation will be in EASE Focus. It is better to gather all of
the information and create the simulation before the event. In most cases there will be an opportunity to
adjust the configuration at the venue therefore remember to take the file with the project and a computer
with application in case you need to modify something last minute.

GENERAL SAFETY RULES

 During the system setup always place pins so the safety lock in engaged so it cannot be pulled out

without releasing it.

 Always use pins provided by the manufacturer and no other objects.
 Before using a pin check if the safety lock is operating properly.
 When system is being ground stacked, make sure the base is stable and it is safe for system not to

collapse.

 To increase the stability, attach the frame to the base.
 Always verify if the hoist and construction is prepared for the load you are about to fly.
 Do not stand under the array. If the system collapses it can cause permanent health damage or even

death.

FLYING BAR MARKINGS

POL-AUDIO SLA 112 can be used only with flying bar provided by manufacturer. Below you can find frame with angles
possible to achieve.

FLYING SYSTEM

When rigging the system, always use the pins according to the marking on suspension system.
Angles between modules should be result of EASE Focus 2 or 3 simulations.

MAXIMUM ARRAY SIZE

Depending on the system configuration maximum size of an array is:

 Flown: 16 modules
 Ground stack: 10 modules

To keep system operational we suggest to undertake periodic inspections at authorised service point. First inspection
should be done around 6 months after the buy. Each next inspection can be done with 2 years frequency.

In case of enclosure cleaning, use cloth with water. Cleaning substances can effect in enclosure damage.

HEARING PROTECTION

We suggest using hearing protection when long exposure to high sound pressure is necessary. If not, temporarily or
permanently hearing damage can occur.

Remember: Hearing is one of our primary working tools. Take care of it.

SPARE PARTS

Manufacturer uses only original spare parts for performing repairs. If system will be repaired in
external service facility with different spare parts, the warranty is no longer valid.

ORIGINAL PRODUCT

When encountered a product that looks like a counterfeit please contact manufacturer. We treat each notification
very seriously. The logo is a warranty of a product quality. Non-original products impact interest of: event organizer,
artists, rental companies and manufacturer. Each notification will be forwarder to appropriate law enforcement
department.
