1. Read these 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 ampliers) that produce heat.

9. Only use attachments/accessories specied by the manufacturer.

10. Refer all servicing to qualied 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 specications 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 specications provided in the instruction manual to know the maximum sound pressure (SPL) the loudspeaker is capable of producing.

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 apparatus.

WARNING! This equipment has been

designed to be installed by qualied 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.

14. Rigging Precautions: When mounting or suspending EAW Commercial loudspeaker enclosures, it is essential that load ratings, rigging techniques, and special safety considerations be appropriate for the installation. Use only the mounting/rigging points on the loudspeaker enclosure intended for this purpose. The user must determine the load requirements, dynamic loading, and any other contributing factors affecting the loudspeaker installation. The user must determine the proper design factor for specic applications and the required load rating of the connection to structure. Comply with all applicable federal, state, and local regulations.

EAW Commercial strongly recommends the following rigging system practices:

• Documentation: Thoroughly document the mounting/rigging design with detailed

drawings and parts lists.

• Analysis: Have a licensed structural engineer or other qualied professional review and

approve the mounting/rigging design before its implementation.

• Installation: Use personnel experienced and qualied for mounting/rigging loudspeakers

in accordance with and in compliance with all federal, state and local regulations. DANGER: Loudspeakers should be mounted or suspended only by persons with knowledge

of the proper hardware and rigging techniques. When stacking or pole-mounting

loudspeakers, be sure that they are stabilized and secured from falling over or being accidentally pushed over. Failure to follow these precautions may result in damage to the equipment, personal injury, or death.

2. INTRODUCTION

Congratulations on the purchase of your new EAW Commercial loudspeaker. You now own one of the nest professional audio products available – the result of exceptional engineering and meticulous craftsmanship. Please read these instructions to get the maximum performance from your new loudspeaker.

Each EAW Commercial loudspeaker is intended for professional use. The construction, components, and hardware have been designed to provide robust, reliable performance for its intended application. Please ensure that you fully understand its proper installation and operation before use.

This manual describes the CLA37 frequency-shaded column loudspeaker. The CLA37 is an economical solution for exceptional delity in speech reinforcement and background music applications. It is especially suited for small to mid-sized spaces with excessive reverberation or problematic sound reections. The drivers and system voicing are designed to maximize vocal range clarity and speech intelligibility, without compromising the broadband frequency response required for pleasing music reproduction.

The CLA37 uses sophisticated, frequency shading to progressively shorten its acoustic length with increasing frequency. The result is a well-behaved nominal vertical beamwidth of 30 degrees to below 1 kHz that eliminates troublesome lobing. In the horizontal plane, the drivers act as direct radiators. A waveguide loads the three center drivers to maintain the nominal 120 degree beamwidth at high frequencies.

The included bracket allows setting the enclosure’s vertical angle for both wall-mounting and suspension. An optional input panel has an integral transformer for 70 V or 100 V distributed applications. The cross-ply laminated birch enclosure is available in either black or white nish, and the powder-coated steel grille is foam-backed to hide the drivers from view.

Features:

• Frequency-shaded, full-range, column loudspeaker

• Seven high-quality 3-inch drivers

• 120 degree horizontal x 30 degree vertical nominal beamwidth

• Passive crossover for economical, single-amplier operation

• Optional 70 V / 100 V multi-tap transformer

• Includes mounting/suspension bracket

• Five-year warranty

3. INSTALLATION

Unpacking and Inspection

Visually inspect the outside of the shipping carton and check for any damage. After unpacking, if you nd concealed damage to the loudspeaker, save the packing materials for the carrier’s inspection, notify the carrier immediately, and le a shipping damage claim. Although EAW Commercial will help in any way possible, it is always the responsibility of the receiving party to le any shipping damage claim. The carrier will help prepare and le this claim.

Mounting Precautions

The mounting bracket provided can be used for wall mounting the loudspeaker.

WARNING: Installation should only be done by an experienced technician. Improper installation may result in damage to the equipment, injury or death. 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.). Due to various construction methods and materials used today, the hardware for securing the bracket to the mounting surface is not supplied. Consult a building professional for the proper mounting hardware before mounting the bracket.

• 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.

• Avoid installing the loudspeaker in places exposed to harsh weather conditions.
