(servicing) instructions in the literature accompanying the apparatus. Follow all instructions. Do not use this apparatus near water. Clean only with a dry cloth. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Only use attachments/accessories specified by the manufacturer. Refer all servicing to qualified 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. The entire sound system must be designed in compliance with the current standards and laws regarding electrical systems. When installing and using this apparatus, keep in mind the technical specifications indicated in the dedicated section of the manual. 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 specifications 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 qualified 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 – CLA37 Duration per day (hours) Sound level (dBA) Typical example Duo in a small club 8 90 6 92 4 95 3 97 2 100 1.5 102 1 105 0.5 110 0.25 or less 115 Subway train Very loud classical music Locomotive at 50 feet Loudest parts at a rock concert Part No. 0012959 Rev.A 09/2004 © 2004 LOUD Technologies Inc.

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 specific 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 qualified professional review and approve the mounting/rigging design before its implementation. • Installation: Use personnel experienced and qualified 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. TABLE OF CONTENTS 1.

You now own one of the finest 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 fidelity in speech reinforcement and background music applications. It is especially suited for small to mid-sized spaces with excessive reverberation or problematic sound reflections. 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 finish, 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-amplifier operation • Optional 70 V / 100 V multi-tap transformer • Includes mounting/suspension bracket • Five-year warranty 4 – CLA37 Applications include: • • • • • • Houses of Worship Transportation Terminals Museums Theme Parks Schools Meeting Rooms 3. INSTALLATION Unpacking and Inspection Visually inspect the outside of the shipping carton and check for any damage. After unpacking, if you find concealed damage to the loudspeaker, save the packing materials for the carrier’s inspection, notify the carrier immediately, and file a shipping damage claim. Although EAW Commercial will help in any way possible, it is always the responsibility of the receiving party to file any shipping damage claim. The carrier will help prepare and file 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 five times the actual load. • Avoid installing the loudspeaker in places exposed to harsh weather conditions.

CONNECTIONS WARNING: To prevent the risk of electric shock, do not connect the loudspeaker with the amplifier switched on. The protective cover over the terminal strip is a safety feature per CE requirements. Replace this cover after making the signal connections. 1. Remove the insulating cover from the loudspeaker input terminal strip. 2. The positive (+) input terminal of the loudspeaker connects to the positive (+) output of your power amplifier. 3. The negative (–) terminal of the loudspeaker connects to the negative (–) output of your power amplifier. 4. Using a small phillips screwdriver, secure the connections. 5. Replace the insulating cover over the loudspeaker input terminal strip. 8 – CLA37 -- + IN PUT CAUTION: SUSPENDING THIS SYSTEM SHOULD BE DONE BY QUALIFIED TECHNICIANS FOLLOWING APPROPRIATE SAFETY STANDARDS Loudspeaker Cables • Use loudspeaker cables with a minimum conductor size for the length you need, as listed in these tables. This will minimize power losses to less than 0.5 dB. The cable lengths listed are “up to” lengths. For in-between lengths, use the next larger conductor gauge. Using larger than the recommended conductor size is always permissible. Using smaller than recommended conductor size will result in higher power losses. Minimum AWG 4 ohm 8 ohm 18 10 ft 25 ft 16 25 50 14 25 75 12 50 125 10 100 200 Min Metric WG 4 ohm 8 ohm 12 3m 8m 14 8 15 8 25 15 40 30 60 • The recommended conductor gauges are listed for AWG (American Wire Gauge) and 16 Metric WG (Metric Wire Gauge). Note that 20 smaller AWG numbers = larger conductors 25 and smaller Metric WG numbers = smaller conductors. The Metric WG is equal to ten times the nominal conductor diameter in millimeters. • For cable lengths over 200 feet / 60 m at 8 ohms, and over 100 feet / 30 m at 4 ohms, the conductor sizes needed for less than 0.5 dB power losses are rarely practical for physical and cost reasons. As a practical compromise for these situations the recommended conductor gauge is 10 AWG or 25 metric. Precautions • 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. • Before using the loudspeaker, carefully check that all the connections have been made correctly to make sure there are no accidental short circuits that could cause electrical sparks. • Verify that the polarity of the connections to all of your loudspeakers are correct. When more than one loudspeaker reproduces the same frequencies, but with opposite polarity, there will be sound cancellations. Therefore, if any of the loudspeakers are wired so that the +/- connection polarity is reversed with respect to the others, incorrect reproduction will result. Most notably, the bass response will suffer. This is especially true when loudspeakers are situated in adjacent positions where the sound waves readily interact with each other. CLA37– 9 5. OPERATION Signal Processing Sometimes external signal processing is desirable to “voice” the loudspeaker to accommodate particular program material, less than optimum acoustics, feedback control, or personal taste. For these purposes, use a suitable electronic signal processor. This can be as simple as a 1/3 octave graphic equalizer or a fully capable DSP (digital signal processor) such as the EAW Commercial DX810, or the EAW MX8750. Choosing a Power Amplifier There is no exact answer to the question of what amplifier size you should use for a loudspeaker. The loudspeaker power rating in EAW Commercial’s specifications only means it has passed a standard power test. This provides a rating that can be used as a point of comparison with other loudspeakers. This rating does not necessarily correspond to the best amplifier size to use nor is it a measure of a “safe” amplifier size to use. Rather, the amplifier should be sized according to both the sound levels required and the type of audio signals that will be reproduced. If you are unsure of how to determine this, consult with a qualified professional or contact EAW Commercial Technical Support. Preventing damage to the loudspeaker is a function of operating your audio system so that the loudspeaker is not stressed beyond its design limits. Operating Tips • Do NOT drive any of your electronic equipment into clipping, particularly the power amplifiers. This can easily damage the loudspeaker. • If driven into clipping, even an amplifier with a power output rating lower than the loudspeaker’s power rating can cause damage to a loudspeaker. • Avoid sustained microphone feedback. This can quickly cause failure of highfrequency drivers. • Avoid extreme boosts on equalizers as these can cause excessive input to the drivers at the boosted frequencies. Generally, cutting frequencies is preferred to adjust the frequency response. • With appropriate signal processing, your loudspeaker should produce exceptionally good sound. If it is used in a room with problematic acoustics, there is little you can do to overcome the room problems with electronic adjustments. Your best solution is careful placement and aiming of the loudspeaker so most of the sound is directed only at the audience. • Most EAW Commercial loudspeakers are capable of sound levels that can be damaging to human hearing. Take precautions so that audiences are not exposed to such levels. If you must expose yourself to these kinds of volume levels, wear adequate hearing protection. • Take care when moving or lifting the loudspeaker. Injury to you or damage to the loudspeaker can result from careless handling. 10 – CLA37 6.

TROUBLESHOOTING Loudspeaker difficulties usually fall into one of the following categories. The causes for each are listed in the most likely order of probability. No Sound or Low Output • Loudspeaker cables or connectors are not wired correctly or are faulty. Check all cabling, referring to these instructions for the correct connections. The best way to check a suspect cable is to swap it with a known good cable. Check the loudspeaker’s input panel to verify correct cable connections. • Electronic equipment is not turned on, or the level controls are not adjusted properly. Make sure that all equipment in the signal path is powered up, and that all controls are set to appropriate levels for normal operation. • Loudspeaker is not working. Connect the loudspeaker cable to a known good loudspeaker, leaving all equipment set to the same levels. If the problem disappears, the loudspeaker is probably not working. Contact EAW Commercial Technical Support for appropriate troubleshooting. Distorted Sound • The power amplifier is clipping. The signal level is exceeding the limits of your system and you must reduce the level. • Other electronic equipment is being overdriven. Ensure that no equipment in the signal chain is being over driven. For example: input(s) or summing bus in the mixing console, equalizers, etc. • Driver(s) not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting. Partial Sound (frequency band missing) • Incorrect EQ settings in the electronic equipment. Ensure that all EQ settings and filters on the mixing console, preamplifier, or other equipment are set for normal operation. Ensure that level controls on electronic crossovers and associated amplifiers are correctly set, and that all cables and connections for such equipment are connected and working properly. • Driver not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting. • The crossover network inside the loudspeaker is not working properly. Contact EAW Commercial Technical Support for appropriate troubleshooting. CLA37– 13 8. SERVICE and MAINTENANCE Maintenance Usually, your EAW Commercial loudspeaker will not require regular maintenance for normal use. However, you can do several things to keep your loudspeaker in good operating and cosmetic condition. • Testing: Periodically test your loudspeaker for proper performance. A simple test is to play a CD through it using well-defined, articulate, wide-range program material. Listen to ensure all drivers are working properly and for any evidence of distortion or other extraneous sounds. Test at several volume levels: very low, normal, and high. • Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected for security, wear, deformation, corrosion, and any other circumstances that may affect the load-handling capability. Immediately remove from service and replace any hardware whose load-handling capability may be compromised. • Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt.” Dust, food spills, or similar contaminants can usually be removed with a cloth dampened with water, or a mild household cleaner. Avoid using any strong solvents as this may damage the finish. Turn the amplifiers off before cleaning. • Scratches or Dents in Wood Enclosures: Minor scratches on the enclosure can be painted over with an outdoor latex paint, or simply a colored in with a “Sharpie” or artist’s marking pen. More serious gouges or dents should be sanded out, filled with wood putty, and repainted. Touch-up paint in pints and quarts is available through EAW Commercial Technical Support.
