WARNUNG:

Verwenden Sie unterkeinen Umständen die Griffe eines Lautsprechers zu anderen Zwecken als dem ursprünglichen: Tragen beim Transport des Lautsprechers. Die Griffe sind nicht fr das Rigging in temporären oder permanenten Installation ausgelegt.

WARNUNG: Das Rigging von Lautprechern ist eine sehr ernste Angelegenheit, die rechtliche Konsequenzen nach sich ziehen kann. Daher ist es unerlässlich, dass diese Aufgabe nur von qualifziertem Personal ausgeführt wird, das alle auftretenden Faktoren kennt und für das die Sicherheit n oberste Stelle steht. Nur Personen mit entsprechender Ausbildung im Bereich des Riggings dürfen diese Arbeiten ausführen. Daher sollte für alle Belange, di das Rigging betreffen, eine qualifizierte Fachkraft konsultiert werden. Das Rigging muss zwingen unter Beachtung und Einhaltung aller nationalen oder lokalen Vorschriften ausgeführt werden.

4.3 Working Load Limits

To maintain the Working Load Limit (WLL) for the rigging points on EAW loudspeakers, support each loudspeaker independently of any other. This means do not use one loudspeaker to support another.

Most EAW loudspeakers have one or more types of rigging fittings, integral with the enclosure. Depending on the loudspeaker, these will be suitable for fixed mounting, suspension, or both. The WLLs for these fittings are defined and listed on the Mechanical Drawing found on the specification sheet for the loudspeaker. If this information is missing from the drawing, contact the Application Support Group. The WLLs do not extend to any rigging hardware attached to these fittings nor to the connection of that hardware to structure.

The WLLs listed are the maximum load that should ever be applied to the fittings under any condition. The WLL assumes a straight, tensile pull, perpendicular to the enclosure surface where the fitting is mounted and that the enclosure and fittings are in like-new condition.

The WLL is the Ultimate Strength (breaking or failure point) divided by the Design Factor. The WLL does not apply to any product that has been altered from its manufactured condition.

If these conditions specified for a WLL are not met, the WLL may require a significant reduction.

Exceptions:

1. Where a WLL is specified in an accompanying manual for a specific loudspeaker model, that rating supersedes this section.

2. Where the loudspeaker is specifically designed for suspension in touring applications.

4.4 Design Factor

The Design Factor for all WLLs is a minimum of 8:1.

Section 5 Rigging Design

5.1 Rigging Design Practices

Rigging a loudspeaker requires determining:

1. The rigging methods and hardware that meet static, shock, dynamic, and any other

load requirements for supporting the loudspeaker from structure.

2. The design factor for and the required WLL (Working Load Limit) for this support.

EAW strongly recommends the following rigging practices:

1. Documentation: Thoroughly document the design with detailed drawings and parts lists.

2. Analysis: Have a qualified professional, such as a licensed Professional Engineer,

review and approve the design before its implementation.

3. Installation: Have a qualified professional rigger do the installation and inspection.

4. Safety: Use adequate safety precautions and back-up systems.

5.2 Rigging Hardware and Accessories

Rigging EAW loudspeakers will invariably require hardware not supplied by EAW. Various types of load-rated hardware are available from a variety of third-party sources. There are a number of such companies specializing in manufacturing hardware for, designing, and installing rigging systems. Each one of these tasks is a discipline in its own right. Because of the hazardous nature of rigging work and the potential liability, engage companies that specialize in these disciplines to do the work required.

EAW does offer certain accessory rigging items, primarily for attachment to the hardware integral with the loudspeaker. Some items, such as eyebolts, can be used with a variety of products. Others, particularly U-brackets and similar hardware, can only be used with a specific product or product Series. While these accessories are intended to facilitate installation, the wide variety of possible installation conditions and array configurations do not permit EAW to determine their suitability or load rating for any particular application.

EAW is not in business of providing complete rigging systems, either as designers, manufacturers, or installers. It is the responsibility of the installer to provide a properly engineered, load-certified rigging system for supporting the loudspeaker from structure as outlined in Section 5.

Section 6 Amplifier Power Requirements

This section does not apply to powered loudspeakers.

6.1 Selecting an Amplifier

As is true of all professional loudspeaker systems, the performance of the loudspeaker depends on an amplifier delivering an adequate supply of clean power. Determining the appropriate power amplifier wattage for a given loudspeaker and application is a subject of some debate within the audio industry. As such, there is no single answer to the question of what amplifier power you should use for a particular loudspeaker. The "Ruleof-Thumb" is an all-purpose metric commonly used for selecting amplifier power. A more exacting approach involves three separate and distinct issues: power ratings, appropriate amplifier size, and preventing loudspeaker damage. These are discussed within this section.

6.1.1 Rule-Of-Thumb For Selecting An Amplifier

If the loudspeakers are used for professional application with competent operators, a rule of thumb can be applied. Where the full output capabilities of the loudspeakers may be needed to achieve appropriate acoustic output levels, EAW recommends amplifiers with ratings up to 1.4 times the voltage, which equals twice the wattage, listed in the loudspeaker specifications. This provides a peak voltage capability of 6 dB above the specified rms voltage limit. This assumes the audio signals will have a peak to average ratio in excess of 6 dB, which is usually, but not always, true. Under this condition, the thermal limits are unlikely to be exceeded. While this rule of thumb is consistent with the EAW's testing parameters, it does NOT guarantee trouble-free operation. See Section 6.1.4

In some cases, the amplifier power determined by the Rule-of-Thumb may not be available in acceptable products. In this event, select an amplifier within approximately +/-25% (+/- 1 dB) of the desired power. In some cases, particularly subwoofers or multiple LF subsystems powered off one amplifier channel or an amplifier in bridged mode, the desired power will exceed that available in acceptable products. In this event, select the largest amplifier possible.

WARNING: The power amplifier sizes recommended by the above rule of thumb are capable of continuous output levels that can cause damage to or failure of the drivers. Exercise caution in operation to avoid exceeding the specified, maximum rms voltage limits. This is especially true when reproducing recorded music. Many recordings have very low peak to average ratios such that much higher continuous levels are possible before amplifier clipping.

6.1.2 Power Ratings

The voltage and/or power listed in EAW's specifications mean that the loudspeaker has passed EAW's standard power-handling test. In this test, the loudspeaker is "exercised" to a point of damage or failure. The voltage and/or power ratings resulting from this test are intended to be used as a point of comparison with the ratings of other loudspeakers. This rating does not necessarily correspond to the best amplifier size to use nor is it a measure of the "safe" amplifier size to use depending on the actual operating conditions.

6.1.3 Selecting An Appropriate Amplifier Size

The amplifier for your loudspeaker should be sized according to both the sound levels required and the type of audio signals that will be reproduced. This requires a considered analysis for the particular application. If you are unsure of how to determine these parameters, consult a qualified audio professional or contact EAW's Application Support Group.

For audio signals with low dynamics, such as heavy metal rock or other highly compressed recorded music, an amplifier with a rating at or below the power handling specification might be needed to avoid overstressing the loudspeaker's thermal capabilities. On the other hand, a loudspeaker rated at 500 W continuous (or rms, continuous, etc.), used to reproduce only background music at low levels, may only need a small 25 W amplifier to reach the desired acoustic level. Thus, the power amplifier size actually required for a given application may be considerably more or considerably less than the amplifier wattage specified as the power handling.

6.1.4 Preventing Loudspeaker Damage

Preventing damage to or failure of a loudspeaker is not a function of amplifier size nor the loudspeaker's power rating. Preventing damage is a function of operating an audio system so that a loudspeaker is not stressed beyond its limits. If an audio system is operated improperly, damage to or failure of a loudspeaker can occur even with an amplifier sized well below the loudspeaker's power rating. Contrarily, if an audio system is operated properly, damage to or failure of a loudspeaker can be avoided even with an amplifier sized well in excess of the loudspeaker's power rating.

It is the responsibility of the audio system operator to ensure that all equipment in the system is operated within its capabilities. This is the only way to ensure that loudspeakers are not stressed beyond their limits to the point of damage or failure. See Section 10.1.

Section 7 Locating the Loudspeaker

7.1 Placement Precautions for Powered Loudspeakers

7.1.1 Ambient Temperatures

If the ambient temperature is high, the amplifiers may overheat if running the system at high output levels. In this case, aiming a fan at the heat sink to increase the airflow past it will usually help.

7.1.2 Temperature Changes

If the loudspeaker is exposed to a rapid temperature change of more that 15° F / 8° C, internal condensation may develop. A good example of this is moving the loudspeaker from outside summer conditions to an air-conditioned environment. Allow the loudspeaker at least 30 minutes to acclimate to any ambient temperature changes before connecting it to the ac mains and operating it. Allow for longer acclimation times for larger temperature changes.

7.1.3 Thermal Switch

To avoid heat damage, amplifiers have a built-in, thermal switch that activates if they

overheat and puts them into a standby mode. When the amplifiers have cooled down to a safe operating temperature, the thermal switch will reset and the loudspeaker will resume normal operation. An amplifier Fault indicator will illuminate if a thermal switch has been activated.

7.1.4 Heat Sink Ventilation

The amplifiers are convection cooled by a large heat sink on the rear of the enclosure. For efficient cooling, it is important to allow at least six inches of free space all around the heat sink area behind the loudspeaker. Air should be able to flow freely from below the heat sink, up around it, and then above the enclosure.

High ambient temperatures can cause amplifiers to overheat, even when operating well below full output. In such cases, aim a fan at the heat sink area to increase the airflow and thus assist with cooling.

7.1.5 Stage Monitor Applications

If you use the loudspeaker on its side for stage monitor applications for vocal monitoring, we recommended that you use at least a 12 dB per octave HPF (High Pass Filter) on the signal, 90 Hz to 100 Hz being a good guideline. This will allow more power for useful monitor frequencies.

Having one side of the enclosure on the floor does restrict the airflow for cooling the amplifiers. In more extreme ambient temperatures of high level operation, an HPF can reduce unwanted lower frequencies from being amplified. This will reduce the overall power and thus reduce the possibility of overheating the amplifiers.

7.1.6 Signal Levels

Keep signal levels low enough so that neither the Clip nor Limit Active indicators are blinking frequently or are on continuously. If they are, turn down the input signal level to avoid overheating the amplifiers.

7.2 Placement Precautions For All Loudspeakers

7.2.1 Outdoor Weather Protection

CAUTION: Do not permanently mount EAW loudspeakers in outdoor environments, unless they are WP versions, normally special ordered. If using powered loudspeakers temporarily outdoors, protect the loudspeaker from moisture. If rain is expected, make sure the loudspeaker is protected by a rain cover.

7.2.2 Magnetic Fields

Loudspeakers generate magnetic fields, unless specifically designed for audio-visual applications where drivers are magnetically shielded to limit the extent of the magnetic field. Therefore, place a loudspeaker at least 2 ft (0.6 m) or more from any TV set or computer monitor. If it causes distortion or a change in the display color, move it further away. Do not place any audio, video, or computer magnetic media near the loudspeaker as the loudspeaker's magnetic field may damage the data.

Section 8 Signal Connections

CAUTION: In spite of the listings below, check the input panel labeling to verify proper connections because of possible design differences or production changes.

8.1 Audio Input Connectors - Unpowered Loudspeakers

8.1.1 Neutrik® NL and Cannon AP® Connectors

The input connector on the loudspeaker will be one of following types with the pin connections as listed.

NOTE: Ensure that the connection polarity is correct. To do this, connect with the "+" terminal on the loudspeaker to the like terminal on the amplifier, normally labeled: "+", positive, or hot. Similarly connect the "-" terminal on the loudspeaker to the like terminal on the amplifier, normally labeled, "-", negative, or ground.

8.1.2 Two Connectors

If the loudspeaker has two NL or AP type connectors, they are wired in parallel so you can "Y-connect" multiple loudspeakers together to a single amplifier channel. This is commonly known as "daisy chaining." This will lower the load impedance on the amplifier. This can be calculated by this formula:

(Nominal impedance single loudspeaker) / (number of loudspeakers daisy chained)

8.1.3 Barrier Strip or Terminal Block Connectors

The proper connections are marked for each terminal on the loudspeaker input label, normally as "+" and "-".

8.1.4 Loudspeaker Wire Gauge

The proper conductor size (wire gauge) to use for the loudspeaker cable is primarily a function of the wire length. The general rule is that lower resistance, in relation to the loudspeaker's impedance, is better. To achieve this, use larger conductor sizes for longer lengths of cable and for lower impedance loudspeaker loads.

To provide a sufficient damping factor (DF) for low frequency drivers, use loudspeaker cable with conductor sizes per the following chart. For cable lengths over 200 feet at 8 ohms, over 100 feet at 4 ohms, and over 50 ft at 2 ohms, the conductor sizes required for an adequate damping factor are rarely practical for physical and cost reasons. While it is recommended to avoid such situations the most practical wire gauge for these situations is 10 AWG / 6 mm

8.2 Audio Input Connections - Powered Loudspeakers

8.2.1 Input Connection

The audio input connector will be a female XLR-3 or a type of terminal block connector. Where both male and female XLR-3 connectors are provided, the input connection can be made to either. Normally, the female connector is used for the input signal, with the male connector functioning as a loop through connector for routing the audio signal to additional loudspeakers.

Connect the output from your signal source (mixing console, microphone, preamp, or other line-level source) to the input connector on the rear panel. This is an electronically balanced input designed to be connected to a balanced signal source, but may be connected to an unbalanced source. However, this WILL create a ground loop, possibly causing excessive noise. See Section 8.3.

Terminal Block Connections: The proper terminal block connector connections are

labeled on the loudspeaker, normally as "+", "-", and a shield (ground) symbol, as shown.

8.2.2 Loop or Thru Connector:

Use this connector to "daisy-chain" the input signal to multiple loudspeakers. For terminal block connections, use multiple wires to each terminal for daisy-chaining.

If the signal processing, including the crossover, is built in, full-range loudspeakers and subwoofers may be daisy-chained together from a single signal source.

8.3 Unbalanced Connections

Connection to an unbalanced signal source will create a ground loop that can result in excessive noise (hum and buzz) in the system. The cause of ground loop noise can be difficult to determine, as sometimes it can even be related to the internal design of some equipment.

For unbalanced-to-balanced connection, use an interconnect cable wired as shown above. The important point is that the shield and the negative signal wire from the powered loudspeaker input are connected at the unbalanced output and usually left "floating" at the balanced input. This wiring scheme does not prevent a ground loop; it is simply the best way to directly wire the interconnection. The usual way to eliminate ground loop noise is by inserting an isolation transformer into the signal path.

WARNING: Do not defeat any safety grounding connection to the ac mains supply to reduce ground loop noise. This is a dangerous and, in many locales, an illegal practice. Failure to follow this warning may result in injury or death.

8.3.1 Input Cable

For line level signals, use cable constructed with a shielded, twisted pair. However, the requirements for portable cables and permanently installed cables are quite different. These will depend on the specific application, meaning the environments to which the cable will be exposed: mechanical, chemical (atmospheric), and/or electrical. These conditions will primarily affect the insulation and the cable construction. For both types of applications, follow all local electrical codes.

Section 9 Signal Processing

9.1 Digital Signal Processor Compatibility

The processing EAW determines for its loudspeakers is used to modify performance characteristics that are stable over time and under use. For this reason, precision in the frequency, amplitude, and phase of the settings are critical for reproducing EAW's settings and to maintaining those settings over time. The only type of readily available equipment that can provide these capabilities is a digital signal processor (DSP).

EAW signal processing settings are based on EAW's MX Series digital processors. Unfortunately, the filter algorithms implemented for digital signal processing vary from manufacturer to manufacturer. Therefore, if a different manufacturer's digital signal processor will be used, it is not enough to merely duplicate the MX Series numerical settings. The transfer functions for the settings must be made similar, meaning not only the magnitude response but also the phase response. If the transfer functions do not match closely then this will actually redesign the loudspeaker's performance with arbitrary results. Contact EAW's ASG Department for assistance about your processor's compatibility with the EAW factory settings.

9.2 Unpowered Loudspeakers

9.2.1 Single-amplified Mode

Signal processing, whether analog or digital, is required for all single-amplified loudspeakers to implement the specified high-pass filter (HPF). Digital signal processing is highly recommended as it can provide not only the required high pass filter, but also better equalization tools, signal delay, limiting, and accurate gain settings. With most DSP units, the settings can be protected from unauthorized changes.

Digital Signal Processing: For certain single-amplified products, DSP is required to achieve the designed performance. This is stated on their specification sheets. In most cases, this design approach was chosen to reduce the complexity of the internal passive components, minimize power losses, and provide far more sophisticated processing to maximize performance. The information in Section 9.2.2 applies to such loudspeakers.

DSP Output Gains: EAW's published processor output gain settings are determined so as to achieve the following conditions. This also applies to gain settings for loudspeakers where the only processing specified is an HPF (High Pass Filter).

Unprocessed Input Signal: EIA-426B spectrum with an average level of 0 dBu / 0.775 V Processed Output Signal: average level of 0 dBu / 0.775 V

Amplifier Gain Settings: The amplifier gain setting for a single-amplified loudspeaker has no bearing on the loudspeaker's inherent performance. Choose the amplifier gain as needed for optimum system dynamic range or as needed for a desired level relative to any other loudspeakers in the system.

9.2.2 Multi-amplified Mode

Signal processing in the form of a digital signal processor (DSP), is required for all multiamplified products.

Factory Signal Processing Settings: The signal processing settings determined by EAW should be fully implemented "as is." They will normally provide excellent results in a variety of venues. These settings are determined from careful laboratory measurements and affect many aspects of the loudspeaker's performance.

DSP Output Gains: EAW's output gain settings are determined so as to achieve this condition. Unprocessed Input Signal: EIA-426B spectrum with an average level of 0 dBu / 0.775 V Processed Output Signal: average level of 0 dBu / 0.775 V for the least sensitive passband.

WARNING: Do not under any circumstances use "generic" or your "favorite" crossover, output equalization, or other settings. Arbitrary settings will actually redesign the loudspeaker's performance with the results being equally arbitrary. Always use EAW's recommended signal processing settings. Performance, in terms of frequency response, beamwidth consistency, output level capability, and wavefront coherency is dependent on the EAW-engineered crossover and other processing settings.

Amplifier Gain Settings - IMPORTANT: In order for EAW signal processing to function properly for multi-amplified loudspeakers, it is critical that all amplifiers for all passbands be set to the same voltage gain, regardless of the amplifiers' power output ratings.

NOTE: The same gain does NOT mean the same input sensitivity, but the same input to output voltage gain. Consult your amplifier manufacturer if this cannot be readily determined. Do not selectively boost or attenuate loudspeaker levels of the amplifiers in order to balance a system. This should be done at the output of the signal processor.

The specific gain setting chosen for the amplifiers has no bearing on the loudspeaker's inherent performance. Choose a gain setting as needed for optimum system dynamic range or as needed for a desired level relative to any other loudspeakers in the system.

9.3 Subwoofer Signal Processing

For subwoofers, a digital signal processor (DSP) is the best method for providing crossover, output equalization, protective high pass filter, and limiting. See Section 9.2.1 for signal processing details. These apply equally to any quantity of subwoofer amplifier channels.

9.4 Unpowered Loudspeakers - Limiters

CAUTION: The assumptions that must be made about how to set a limiter and what a driver's power handling limits are cannot address all conditions of use. As such, limiters cannot provide absolute protection nor provide any guarantee against damage or failure from excessive inputs. At best, they can only provide some degree of protection.

9.4.1 Limiters And Limiting

Limiters can help avoid either of two things, depending on the signal frequency content and the amplifier / driver power ratings. The choice depends on which will be exceeded first.

Exceeding a Loudspeaker's Thermal Limit: The limiter is used to prevent the amplifier, operating within its capabilities, from

exceeding the loudspeaker's capabilities.

Exceeding the Amplifier's Output Limit (Clipping). The limiter is used to prevent the amplifier from exceeding its capabilities, even though

the loudspeaker is operating within its capabilities.

9.4.2 MX8750 Limiter Design

EAW has done the work of determining the MX8750's limiter characteristics with real audio signals by performing a number of tests on its behavior with real audio signals and analyzing how this relates to both loudspeaker power handling limits and sonic performance. Based on measurement and analysis of the above variables, EAW Engineering was able to formulate a set of "rules" for setting MX8750 limiters. Listening tests determined settings that maintain good sound quality while maximizing protection. These rules are incorporated into the MX8750 Output Limiter Wizard. See Section 9.4.3.

Because limiters differ in their behaviors from manufacturer to manufacturer, EAW can only provide limiter settings for its own MX Series of processors. These are the only ones on which the required analysis was done to optimize settings. As such, EAW limiter thresholds are only valid for use with an EAW MX8750 digital processor and with amplifiers that have or are set to 32 dB gain for all passbands. This assumes that the factory gain settings for the processor outputs are also used. For amplifiers with gain other than 32 dB and for loudspeakers where no factory limiter settings exist, use the MX8750 Output Limiter Wizard to determine the correct limiter threshold settings. See Section 9.4.3.

9.4.3 MX8750 Output Limiter Wizard

The MX8750 Output Limiter Wizard is an Excel-based program intended to provide limiter settings that can help protect loudspeaker drivers from damage or failure. The program can be downloaded from the EAW web site.

Apply the settings determined from the Wizard to the MX8750 using the MXWare control program.

NOTE: The Wizard's settings apply only to the MX8750. They should not be applied to other limiters for the reasons stated above.

9.5 Powered Loudspeakers

9.5.1 External Processing

Powered loudspeakers have built-in, factory set, signal processing. The settings were determined to provide the maximum performance in terms of frequency response, phase response, power handling, and audio quality. In some cases, acoustical conditions, program material, or personal taste may require additional equalization or signal processing, such as signal delay. In such cases, use external analog or digital equalizers or other signal processing. Avoid radical or extreme equalizer settings.

9.5.2 Limiters

Powered loudspeakers have built-in, factory set limiting. The limiter characteristics and settings were determined to provide the maximum protection possible, to minimize the sonic effects, and to integrate closely with the amplifier capabilities. Defeating such limiting and/or using an external limiter could expose the drivers or amplifiers to operation beyond their limits.

External limiting should only be used to limit the maximum output to some level below that allowed by the factory limiting. In this case, choose limiter settings that minimize the sonic effects when the limiting is active.

Section 10 Operating the Loudspeaker

10.1 Operating Limits

10.1.1 Operator Responsibility - Preventing Damage

It is the responsibility of the audio system operator to operate the loudspeaker within its limits and capabilities. This is the only way to ensure that the loudspeaker is not stressed beyond its limits to the point of damage or failure.

10.1.2 Loudspeaker Limits - Preventing Damage

Operation beyond the loudspeaker's capabilities usually includes, but is not limited to, one or more of the following conditions:

1. Amplifier clipping

2. Voltage input in excess of the specified rms voltage limit

3. Peak voltage input in excess of twice the specified voltage limit

4. Noticeable distortion

5. Mechanical noise (such as a cone bottoming out)

6. A suitable means for determining these conditions is highly recommended. At a minimum, the operator should have a meter display calibrated to indicate when the loudspeaker's maximum rms voltage limits will be exceeded. This assumes amplifiers are not being driven into clipping at these limits.

10.2 Acoustic Level Precautions

CAUTION: If exposure to levels higher than 100 dB will be prolonged, wear earplugs in the ear canals or ear protectors over the ears.

ATTENTION: Si l'exposition à un niveau sonore supérieur à100 dB doit être proongée, portez des protections auditives dans les oreilles ou sur les oreilles.

CAUTELA: In caso di esposizione prolungata a livelli superiori a 100 dB, si consiglia l'impiego di tappi per le orecchie oppure di indossare cuffie protetive.

PRECAUCION: Si a a quedar expuesto a niveles superiores a los 100 dB durante un periodo prolongado de tiempo, colóquese tapones o cascos de protección en los oídos.

GEFAHR: Wenn Sie längere Zeit höheren Pegeln als 100 dB ausgesetzt sind, sollten Se einen Gehörschutz inden Gehörgängen oder über den Ohren tragen.

10.2.1 Operating Levels

EAW loudspeakers, when appropriately powered, are capable of producing sound levels that are potentially damaging to your hearing. For a single loudspeaker and depending on the product, this can easily occur within 50 ft / 15 m of the loudspeaker. When used in multiples, such levels can be reached at considerable distances from the loudspeakers.

Avoid operating the loudspeaker systems at levels that exceed 100 dB PL in the listening area for more than short periods. One way to do this for musical performances is to provide some moderate boost at the very low and to a lesser extent, at the very high frequencies. Judicious applications of this type of equalization can make a loudspeaker sound significantly louder than it actually is. Both your listeners and your loudspeakers will thank you. It is recommended that a sound level meter be used to verify listening levels. Relatively inexpensive meters are available that provide adequate accuracy for this purpose.

Be aware that audience members will not have the benefit of ear protection. Therefore, if you need to use ear protection because the levels are loud, the audience also needs ear protection. The remedy is to reduce the system volume to a safer listening level.

10.3 Testing and Test Signals

Loudspeakers are designed to reproduce primarily speech and music audio signals. Such signals are highly variable from moment to moment in their level, frequency content, and phase. Accepted loudspeaker measurements and tests that are accurate and consistent are possible only with signals where the level, frequency content, and phase are accurately known and consistent at all times. Such signals include sine waves, swept tones, pink noise, white noise, and other constant level test signals. These are much harder on a loudspeaker than speech and music signals and therefore the potential for damage is much greater. Keep in mind that the parameters of electronic limiters are also designed for the characteristics of speech and music signals - not test signals. Their capability to protect the loudspeaker is considerably reduced using test signals.

Take certain precautions to avoid loudspeaker damage when using test signals. Never use power inputs that exceed 50% (-3 dB) of the loudspeaker's power rating and do not test at this level for more than a few moments. For sine waves and for any other test signals that must be used for extended periods of time, the input to the loudspeaker should be kept below 10% (-10 dB) of the loudspeaker's power rating.

10.4 Measurements

The SmaartLive™ computer program, from SIA Software Company, is an ideal tool to use to measure and optimize a loudspeaker system or loudspeaker array for a particular venue. This is a fast, yet sophisticated, process that will indicate problem areas due to particular venue characteristics. Usually it is a matter of applying small amounts of equalization to adjust significant anomalies.

While there are a number of other commercially available and quite sophisticated measurement programs, they are not specifically optimized for measurements of loudspeakers in use, but rather for laboratory type measurements. On the other hand SmaartLive provides the major benefits of using a test signal, including music, for the measurements and providing continuous, real-time data for making system adjustments.

A demo version of SmaartLive is available at www.siasoft.com.

10.5 Operating Tips To Help Avoid Loudspeaker Damage

1. Do NOT drive any of your electronic equipment into clipping, particularly the power amplifiers. This can easily damage the loudspeaker.

2. If driven into clipping, even an amplifier with a power output rating lower than EAW's power rating can cause damage to a loudspeaker.

3. Avoid sustained microphone feedback. This can quickly cause driver failure.

4. Avoid extreme boosts on equalizers as these can cause excessive input to the drivers at the boosted frequencies. Generally, cutting frequencies is preferred to correct for frequency response problems. These problems include attenuating feedback frequencies or reducing excessive energy at certain frequencies due to room acoustics.

5. With appropriate signal processing, your loudspeaker should produce exceptionally good sound. If used in a room with problematic acoustics, there is little you can do to overcome these problems with electronic adjustments. Your best solution is careful placement and aiming of the loudspeaker so that most of the sound is directed only at the audience.

EAW 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.

7. Take care when moving or lifting the loudspeaker. Careless handling can result in equipment damage, injury, or death.

Avoid exposing the loudspeaker to extreme cold (below freezing temperature). If you must operate the loudspeaker in a cold environment, warm it up by sending a fullrange, low-level signal through it for about 15 minutes prior to high-power operation.

Section 11 Inspection and Maintenance

Your EAW loudspeaker should require little to no regular attention for normal use. However, performing regular inspections and maintenance can ensure your loudspeaker remains in optimum operating and cosmetic condition.

11.1 Periodic Inspection

DANGER: If there is any question about the integrity or capability of any part used to rig a loudspeaker to perform its intended function, immediately remove it from service for repair or replacement.

DANGER: En cas de doute sur l'intégrité ou la capacité d'un des éléments à assurer correctement sa fonction dans un montage ou une suspension d'enceinte(s), retirez immédiatemnt ce ou ces éléments de la structure, faitesles vérifier ou réparer par un personnel compétent, ou remplacez-les.

PERICOLO: Se dovesse esistere qualche dubbio riguardo all'integrità o alla capacità di qualsiasi parte utilizzata nel montaggio / sospensine di un diffusore, di essere in grado di espltare la funzione alla quale è preposta, è necessario rimuoverla per verificarne la condizione ed effettuare la riparazione o la sostituzione.

PELIGRO: Si tiene cualquier duda acerca de la integridad o capaciad de cualquier pieza o aparato para realizar l función para la que ha sido diseñado a la hora de usarlo para el anclaje de un altavoz, sustitúyalo inmediatamente por otro y/o envíelo al servicio técnico para su reparación.

GEFAHR: Wenn ein Zweifel in Bzug auf die Sicherheit bei einem Bauteil aufkomm, das zum Rigging eines Lautsprechers verwendet werden soll, so muss dieses Bauteil sofort repariert oder ersetzt werden.

11.1.1 Overall Physical Inspection

Perform complete and thorough inspections of the loudspeaker on a routine, periodic basis. The interval between inspections and scope of the inspections will depend on the installation and the conditions of use. It is strongly recommended that the interval between inspections not exceed 1 year.

Inspect for problems and abnormalities, including, but not limited to:

1. Cracks or breaks in the wood

2. Cracks or bends in the grille

3. Loose or missing hardware

4. Damaged mounting/rigging hardware and components

5. Loose input connections

11.1.2 Rigging Inspection

Specifically and thoroughly inspect all rigging hardware and components used to support the loudspeaker. Do this on a routine, periodic basis, whether components are integral with or external to the loudspeaker or whether factory or user-supplied. The interval between inspections and scope of the inspections will depend on the installation and the conditions of use. The rigging inspection interval must not exceed 1 year.

Inspect for problems and abnormalities including, but not limited to:

1. Bends

2. Breaks

3. Broken parts

4. Corrosion

5. Cracks

6. Cracks in welded joints

7. Deformation

8. Denting

9. Wear

10. Holes

11. Loose or missing parts or fasteners

11.2 Periodic Performance Testing

Periodically perform listening tests and/or formal acoustical measurements for proper performance. The interval between such tests will depend on the frequency of system usage and the conditions of use.

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.

All drivers should be tested for functionality and proper performance. A sine wave sweep at approximately 10% of rated power will usually reveal driver and/or enclosure problems in the form of distortion, buzzes, or rattles.

11.3 Periodic Maintenance

11.3.1 Periodic Acoustical Maintenance

Normally, no periodic maintenance, beyond the testing and inspections detailed in Sections 11.1 and 11.2, is required to maintain the acoustical performance.

11.3.2 Routine Maintenance

Periodically do routine maintenance on the loudspeaker. The interval between maintenance times and the scope of the maintenance will depend on the installation and the conditions of use. It is strongly recommended that maintenance intervals not exceed 1 year.

Maintenance shall include but not be limited to:

1. Repair or replace of any item determined by inspection to be sub-standard for their intended use.

2. Replace any load supporting parts whose load handling integrity is the least bit questionable.

3. Lubricate all parts subject to friction using WD-40, Scott oil FS365, or similar. These are water-based lubricants with machine oil, surfactant, an anti-rust treatment.

4. Tighten all accessible screws, nuts, and bolts, especially those that are part of the rigging hardware.

5. Clean the exterior surfaces of the enclosure and rigging system as required, this largely depending on the type of "dirt". Normally, use a cloth dampened with mild soapy water to remove dust, dirt, food spills or similar. Avoid getting moisture into any of the openings of the cabinet, particularly where the drivers are located. After cleaning, use a clean dry cloth to remove any excess moisture and treat metal parts and the rigging system with lubricant to prevent rusting.

CAUTION: For powered loudspeakers, do cleaning only when the power is turned off.

CAUTION: To avoid damaging the exterior finishes do not use cleaning solvents or

abrasives.

11.3.3 Cosmetic Maintenance

While the paint finish and the wood used for the enclosures are of high quality and durability, mars, marks, scratches, and other blemishes may appear from normal handling. For cosmetically damaged wood, repair such damage using common woodworking methods and materials as appropriate for the damage. Scratches on the enclosure or hardware can be painted over with an outdoor latex paint or simply 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. Black touch-up paint in pints (part #810050) or quarts (part #810049) is available from the EAW Service Department. Tips for repainting are on EAW's website.

11.3.4 Long Term Maintenance

For approximately five years, only routine inspections, performance testing, and maintenance are normally required to maintain the loudspeaker's performance. Over a longer period, there are possible, additional maintenance issues:

Ferrofluid: Some EAW loudspeaker models employ compression drivers with Ferrofluid-filled

magnetic gaps. This magnetic fluid fills the loudspeaker's magnetic gap to cool the driver by transferring heat from the voice coil through the fluid to the magnet structure. Over time, the Ferrofluid can thicken enough to affect the acoustical response and should be replaced. For normal conditions of use, Ferrofluid will retain its original properties for 6 years or more. However, if a loudspeaker is driven very hard on a daily basis, the Ferrofluid may retain its properties for only 2 years.

When either of these conditions of use apply, replace the Ferrofluid to restore performance. Contact the EAW Service Department for instructions.

Grille Material: Some EAW loudspeaker grilles are backed by either cloth or foam. This material can

deteriorate over time due to various environmental conditions and effects, particularly if installed outdoors. If these conditions of use apply, periodically inspect and replace any deteriorated grille material. Contact the EAW Service Department for materials and instructions.

Cosmetics: Various finishes are used on loudspeaker enclosures depending on the product and its

applications. While these finishes are designed to be durable over long periods, like any applied finish, they can deteriorate over time, largely depending on the conditions of use. While this deterioration will not affect performance, refinish the loudspeaker as needed for aesthetic reasons. Contact the EAW Service Department for instructions.

Section 12 Troubleshooting

12.1 Rigging Problems

Because of the potential serious consequences and liabilities due to faulty rigging, contact the EAW Service Department to determine the appropriate service solution for any problems with the rigging hardware integral to the enclosure or EAW rigging accessories.

12.2 Enclosure and Integral Hardware

Enclosure problems, such as loose hardware, faulty joints, or other structural problems, will usually be heard as distinct buzzes, rattles, or other unwanted noises. To test for enclosure problems, use a sine wave signal manually swept on the LF sub-system. The input level should be varied, because certain problems can be level as well as frequency specific. However, in no circumstances should the sine wave level be higher than 6 dB below rated power (equal to no higher than 1/2 rated rms input voltage). It may be possible to field-repair some enclosure problems.

12.3 Cosmetics

While the paint finish and the wood used for the enclosures is of high quality and durability, mars, marks, and other blemishes may appear from normal handling for an installation. For paint touchup, use good quality latex paint. For a more permanent and cosmetically correct appearance, contact the EAW Service Department for the paint specifications or to purchase small quantities for touch-up. For cosmetically damaged wood, use common woodworking methods and materials as appropriate for the damage.

12.4 Isolated Sonic Problems

12.4.1 What is Involved

Loudspeakers invariably consist of an input panel, internal components and wiring, drivers, and an enclosure. All internal components - drivers, crossover/filters, and wiring

- are accessible from the front of the enclosure by detaching the grille and removing the MF/HF horn and/or woofers.

Troubleshooting for various performance problems usually involves isolating the problem to one of these areas. In most cases, the fault can be clearly isolated to one of them and that will determine the appropriate action for servicing.

1. Drivers

2. Input panel, internal crossover/filter components, and wiring (unpowered loudspeakers)

3. Internal electronics (powered loudspeakers)

4. Enclosure and integral hardware

If no problems can be traced to any of these items, look for problems with external electronics or cabling. Troubleshooting these items is beyond the scope of this manual.

12.4.2 Drivers

A faulty driver will usually cause readily audible distortions or other unwanted noises. In other cases, they may stop functioning. Use your ears and test signals or other sound source to determine which one is at fault. Normally, a faulty driver requires return for service or replacement by EAW.

12.4.3 Input Panel and Wiring

Faults with these items will usually cause a driver to stop working or be intermittent.

For unpowered loudspeakers:

Check wiring continuity from the input jacks to the crossovers and from the crossovers to the driver terminals. Many faults in this area can be field-repaired.

For powered loudspeakers:

Check wiring continuity at the input jacks and from the amplifier(s) to the driver terminals. Many faults in this area can be field-repaired.

12.4.4 Crossovers

NOTE: This section does not apply to powered loudspeakers.

Faults with these items will usually cause drivers to stop working, be intermittent, or alter the frequency response. If a crossover fault is suspected, the nature of the fault determines the action. A poor connection or obviously open circuited, shorted, or physically damaged component (such as from overheating) can be relatively easy to find and fieldrepair. An improperly functioning component may require more sophisticated troubleshooting, as the fault will likely be frequency dependent. A faulty crossover is best returned for service or replacement by EAW.

12.4.5 Enclosure and Integral Hardware

Enclosure problems, such as loose hardware, faulty joints, or other structural problems, will usually be heard as distinct buzzes, rattles, or other unwanted noises. To test for enclosure problems, use a sine wave signal manually swept on the LF sub-system. The input level should be varied, because certain problems can be level as well as frequency specific. However, in no circumstances should the sine wave level be higher than 6 dB below rated power (equal to no higher than 1/2 rated rms voltage). It may be possible to field-repair some enclosure problems.

12.5 Problem Symptoms

Loudspeaker difficulties usually fall into one of the following categories. The causes for each problem are listed in the most likely order of probability.

12.5.1 No Sound or Low Output

1. Loudspeaker cables or connectors are mis-wired or faulty: Check all cabling. Refer to these instructions for correct loudspeaker cable connections. The best way to check a suspect cable is to swap it with a known good cable. Read the loudspeaker's input panel to verify correct cable connections.

2. Electronic equipment is not turned on or 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.

3. Loudspeaker is not working: Connect the signal 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 Service for appropriate troubleshooting.

12.5.2 Distorted Sound

1. The power amplifier is clipping: The signal level is exceeding the limits of your system and you must reduce the level.

2. Other electronic equipment is clipping: Ensure that no equipment in the signal chain is being overdriven. For example: input(s) or summing bus in the mixing console, equalizers, etc.

3. Driver(s) not working properly: Contact EAW Service for appropriate troubleshooting.

12.5.3 Partial Sound (Some Frequency Bands Missing)

1. Incorrect EQ settings in the electronic equipment: Ensure all EQ settings and filters on

the mixing console or preamplifier and on other equipment are set for normal operation. Ensure level controls on electronic crossovers and associated amplifiers are correctly set and that all cables and connections for such equipment are working properly.

2. Incorrect processor configuration: Make sure the processor configuration is correct

for the loudspeaker and its intended mode of operation. This includes settings made using software for powered loudspeakers.

3. For unpowered loudspeakers: Incorrect mode switch settings on the loudspeaker

input panel. Ensure this switch is set for the operating mode you are using: single, bi-amplified or tri-amplified.

4. For powered loudspeakers: Incorrect control switch settings on the loudspeaker

input panel. Ensure switch settings are correct for the application.

5. Driver(s) not working properly: Contact EAW Service for appropriate

troubleshooting.

6. The crossover network inside the loudspeaker is not working properly: Contact EAW

Service for appropriate troubleshooting.

12.5.4 Powered Loudspeaker Electronics

Some faults with the electronics will normally be indicated by an Amplifier Fault indicator. Others should clearly be indicated by an outright malfunction in the sound output. Such malfunctions can include:

1. No or very low sound output

2. Highly distorted sound

3. Bad frequency response, such as the loss of low or high frequencies

4. Intermittent sound

5. Excessive electronic noise

In the case of malfunctioning electronics, contact the EAW Service Department for troubleshooting and repair instructions.
