The lightning flash with arrowhead symbol within an equilateral triangle is
intended to alert the user to the presence of uninsulated "dangerous voltage"
within the product's enclosure, that may be of sufficient magnitude to constitute
a risk of electric shock to persons.
Le symbole éclair avec point de flèche à l'intérieur d'un triangle équilatéral est
utilisé pour alerter l'utilisateur de la présence à l'intérieur du coffret de "voltage
dangereux" non isolé d'ampleur suffisante pour constituer un risque d'éléctrocution.
The exclamation point within an equilateral triangle is intended to alert the user
of the presence of important operating and maintenance (servicing) instructions
in the literature accompanying the appliance.
Le point d'exclamation à l'intérieur d'un triangle équilatéral est employé pour
alerter les utilisateurs de la présence d'instructions importantes pour le fonctionnement et l'entretien (service) dans le livret d'instruction accompagnant l'appareil.
1. Read Instructions
2. Keep these Instructions
3. Heed all Warnings
4. Follow all Instructions
5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any ventilation openings. Install in
accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as
radiators, heat registers, stoves, or other apparatus
(including ampliers) that produce heat.
9. Only use attachments/accessories specied by the manufacturer.
10. Refer all servicing to qualied service personnel. Servicing is required when the apparatus
has been damaged in any way, such as liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has
been dropped.
11. The entire sound system must be designed in compliance with the current standards and laws
regarding electrical systems.
12. When installing and using this apparatus, keep in mind the technical specications indicated in the
dedicated section of the manual.
13. Exposure to high sound levels can cause permanent hearing loss. The sound pressure level which
leads to hearing loss varies considerably from one person to another, and depends on the duration
of exposure. The U.S. Government’s Occupational Safety and Health Administration (OSHA) has
established the maximum sound pressure levels that can be with stood without causing damage,
which are shown in the table below. According to the OSHA regulations, any exposure over the
maximum limits indicated in the table can reduce the hearing capacity of a person. To prevent
potentially dangerous exposure to high sound pressure levels, anyone subjected to such levels
must use suitable protection. When a EAW Commercial product capable of producing high sound
levels is being used, it is therefore necessary to wear ear plugs or protective earphones when
the limits shown in the table are exceeded. Consult the specications provided in the instruction
manual to know the maximum sound pressure (SPL) the loudspeaker is capable of producing.
WARNING! This equipment has
been designed to be installed
by qualied professionals
only! There are many factors
to be considered when
installing professional sound
reinforcement systems,
including mechanical and
electrical considerations, as
well as acoustic coverage
and performance. EAW
Commercial strongly
recommends that this
equipment be installed only by
a professional sound installer
or contractor.

2. INTRODUCTION
This manual describes the CLA series of column loudspeakers (CLA2, CLA4 and CLA6).
These compact loudspeakers offer an attractive design and good acoustic features for quality
speech and music reproduction.
The extended-range drivers guarantee high efciency, and a wide angle of coverage over
the entire range reproduced. Each loudspeaker is equipped with an internal line transformer
that makes it possible to connect it to constant voltage sound systems at 70 V or 100 V.
An easily accessible rotary switch allows you to select a range of ve output power
values. A low cut switch is provided for reducing the level of the frequency range below 400
Hz for clear speech reproduction.
The galvanized steel body and metal grill are very sturdy, and the white color allows the
CLA series to be easily integrated into any environment. The shape of the back of the body
allows positioning in corners, and the light weight makes it possible to install them in false
ceilings. Two L-type brackets are included.
Applications include:
• Houses of Worship
• Museums
• Theme Parks
• Transportation Terminals
• Retail Spaces
• Commercial Ofces
• Conference Rooms
• Schools
• Distributed Systems

3. INSTALLATION
The two support brackets provided can be used for installing the sound column on the
wall or ceiling. Use the supplied bolts, plain washers and split lock washers to bolt the
brackets to the loudspeakers.
WARNING: Make sure that the loudspeaker is installed in a stable and secure
way in order to avoid any conditions that may be dangerous for persons or structures:
• Check to make sure that the support surface (e.g., wall, etc.) has the necessary
mechanical characteristics to support the weight of the loudspeaker without the
danger of it falling.
• Always use support elements suitable for the material of the wall that will support
the loudspeaker (e.g., screw anchors for bricks, screw anchors for cement, etc.).
• Before suspending the loudspeaker, carefully check all the components to be used to
make sure there is no damage, deformation, corrosion and/or missing or damaged
parts that could reduce the safety of the installation.
• Consult a professional rigger or structural engineer prior to suspending loudspeakers
from a structure not intended for that use. Always know the working load limit of the
structure supporting the loudspeaker. Always make sure that the rigging hardware
minimum rating is at least ve times the actual load.
Installation precautions
• Use speaker cables with an adequate cross-section (gauge). The greater the distance
between the amplier and loudspeaker, the larger the connection cable cross-section
should be.
• To prevent inductive phenomena causing humming or distortion, the speaker cables
should not be run together with electrical energy conductors, microphone cables,
or line-level audio lines. Use speaker cables that have markings to distinguish the
polarity, such as insulation or conductors of different colors.
• Avoid installing the loudspeaker in places exposed to harsh weather conditions.

WARNING: To prevent the risk of electric shock, do not connect the loudspeaker or
adjust the power selector with the amplier switched on.
The loudspeaker is designed to be connected to constant-voltage audio lines at 70 V or 100 V.
1. The white wire of the loudspeaker connects
to the positive amplier output, the black
loudspeaker wire connects to the negative
amplier output.
2. Use a suitable tool to crimp the two
supplied wires to the ends of your audio
line conductors. Insulate the joints.
3. Using a small at screwdriver, rotate
the power selector switch to the desired
setting. The specications section on the
next page shows the power settings for the
three CLA loudspeakers.
4. If your system does not need to reproduce
low frequencies, set the 400 Hz Low Cut
switch to the ON position. This will reduce
the output levels of the frequency range
below 400 Hz.
Precautions
• Before using the loudspeaker, carefully check that all the connections have been

audio line must not exceed 80 % of the amplier’s output power.
phase.” When different loudspeakers reproduce the same frequencies but with
phase differences, there may be sound cancellation. Loudspeakers are often
situated in adjacent positions and the sound waves interact with each other.
If a loudspeaker is connected incorrectly; i.e., the polarity of the audio line
conductors is inverted, the audio signals are transmitted with differences in
phase and correct reproduction is therefore jeopardized. Most notably, the bass
response may suffer.
