SAFETY PRECAUTIONS

For your own safety, as well as that of your colleagues and your audience, please:

-carefully read the following safety precautions and operating instructions prior to operation

-observe the following safety precautions and operating instructions during operation and

-store this manual in a safe place for future reference.

Thank you.

Caution! EUROLIVE speakers are not designed to be suspended!

EUROLIVE SERIES enclosures are designed exclusively for floor-mounteduse. Although the enclosures will withstand rough handling over many years, they are not designed to be suspended. If suspension of the speakers is unavoidable, please be sure that suitable fixtures are mounted by qualified personnel.

Suspension of your EUROLIVE enclosures will always be at your own risk!

Check the condition of the protective corners:

EUROLIVE loudspeaker enclosures are equipped with interlocking protective corners, which allow for slip-freestacking. Damaged corners reduce the stability of speaker stacks. Please inspect them at regular intervals and replace damaged corners immediately.

Safe speaker installation:

-Be sure to mount your speakers on a solid, stable and level base or stand. Vibrating floors (e.g. elements/ components on the stage), as well as tables, chairs or similar objects do not provide reliable support for speaker enclosures or stacks.

-Setting up your speakers at a distance from the audience area, dance floor, musicians and/or personnel will minimize the risk of accident.

-Should local conditions prevent you from following these safety precautions, please be sure to secure the speakers so that they cannot fall or be knocked over. Always consult a P.A. or rigging expert.

Prevention of speaker damage:

Please protect your speakers from damage due to objects or liquids entering the enclosure.

Damage and repair:

EUROLIVE enclosures must be repaired by qualified personnel if:

-objects or liquids have entered the enclosure,

-the speakers have been subject to rain or excessive moisture,

-the enclosure does not work properly or displays obvious performance deterioration or

-the enclosure has been dropped or otherwise physically damaged.

Maintenance:

Maintenance or modifications which may be carried out by the user is defined in the user’s manual. Any additional maintenance/repair work should be carried out by qualified service personnel only.

1. INTRODUCTION

EUROLIVE SERIES

2. OPTIMUM PERFORMANCE

The EUROLIVE SERIES was designed for use in a variety of applications. Naturally, the sound of your speaker enclosures largely depends on the acoustic properties of the environment in which it is used. The following points should help you get the most out of your EUROLIVE speaker system.

2.1HF driver

High frequencies are a crucial part of the audio spectrum, which ensures clear sound and speech intelligibility. Whereas these frequencies are the most easily located, they are also the first to be acoustically blocked. We therefore recommend that you set up your speakers so that the HF driver is situated slightly above the heads of the audience. This will ensure not only optimal dispersion of the high-frequencycontent, but also considerably improved speech intelligibility and clarity.

2.2Avoiding feedback

Always place the “front-of-house”speakers (the enclosures facing the audience) in front of the microphones. Use professional floor wedges (e.g. EUROLIVE F1220 or F1520), so that the performers on stage can hear themselves.

2.3Avoiding feedback when using turntables (e.g. DJ applications)

Turntables often produce low-endfeedback: low frequencies are fed back to the pickup arm and cartridge and reproduced again by the speakers. Common causes oflow-endfeedback are speakers set up too close to the turntable, rooms with a wooden floor or elements placed on the stage. In such cases, try moving the speakers away from the turntable or off the stage and placing them on a solid support. Another possibility is to mount the enclosures on stands, thus minimizing direct contact between floor and speakers.

2.4Protecting your speakers with a low-cutfilter

Low-frequencyrumble or extreme low frequencies can lead to an excessive displacement of the speaker diaphragm and in turn to permanent damage. Using an equalizer or alow-cut/high-passfilter to eliminate the low frequencies below the response curve of the speaker can effectively prevent this. Most equalizers and sound enhancers provide alow-cutfunction (e.g. BEHRINGERULTRA-GRAPHPRO GEQ3102).

The use of a low-cutfilter in the signal path is especially recommended when using turntables and/or CD players as signal sources. CD players often produce extremely low frequencies, which can lead to excessive diaphragm displacement.

3. OPERATING MODES

With the exception of the B1020, all EUROLIVE SERIES multi-waysystems can be operated in two various modes:FULL-RANGEandBI-AMPING.The subwoofers can either be operated in ACTIVE(BI-AMPING)or PASSIVE mode. Use the switch on the rear panel of the enclosure to select the appropriate mode for your application (see chapter 3.3). In both modes, the speakers are connected using the Speakon® inputs.

+Never change the operating mode while an audio signal is present.

3.1FULL-RANGEoperation

All EUROLIVE models are equipped with a built-inpassive crossover network, which ensures a smooth transition between the individual frequency ranges inFULL-RANGEmode. This mode is particularly suitable for applications that require only asmall-scalesetup, such as speech applications in churches and schools, sound reinforcement in small clubs etc.

3. OPERATING MODES

7

EUROLIVE SERIES

3.2 BI-AMPINGoperation

3.2.1 Advantages

BI-AMPINGgives you a number of important advantages: lower distortion, greater flexibility of signal transmission and improved overall system performance.

3.2.2 Selecting the crossover frequency

For operation with an external crossover network such as our BEHRINGER SUPER-XPRO CX2310, please refer to chapter 6 “SPECIFICATIONS” for recommended crossover frequencies. We recommend using a slope of at least 12dB—highervalues will improve performance. A slope of 24 dB is ideal.

3.3 ACTIVE (BI-AMPING)/PASSIVEsubwoofer operation

EUROLIVE SERIES subwoofers also feature an integrated crossover. Driven in passive mode, the B1500X subwoofer perfectly complements our multi-waysystem B1020, resulting in a compact,well-balancedand sonically accurate system. If you wish to operate your subwoofer in active mode (switch toBI-AMPING),it can be combined with virtually any of the remaining EUROLIVEmulti-waysystems.

+To ensure optimal performance in combination with the B1020, the polarity of the B1500X subwoofer has been reversed (180°) in the factory. For operation with any other EUROLIVE multi-wayenclosure, the loudspeaker polarity must be reversed by qualified service personnel.

We designed the B1800X as the perfect subwoofer for the EUROLIVE multi-wayenclosures B1220 and B1520. Of course, the B1800X can also be operated either in passive or active mode.

The foregoing recommendations are only intended to demonstrate the interaction of various EUROLIVE enclosures. You may, of course, combine enclosures as you like, depending on your personal preferences and applications.

3.4 Looping through subwoofer signals

All EUROLIVE SERIES subwoofers are equipped with two parallel Speakon® connectors. Pins2-/2+are directly connected to the loudspeaker. Pins1-/1+can be used to loop signals through, while thehigh-passsignal is present on pins1-/1+(output). Please refer to the instructions in chapter 4.

+Please note that switching the EUROLIVE subwoofers to BI-AMPINGmode moves the input signal of the loudspeakers to pins2-/2+.In this case, pins1-/1+act as aloop-through!

5. WHAT ELSE SHOULD BE CONSIDERED?

5.1Length and gauge of speaker cables

Low-gaugespeaker cables can considerably reduce the performance of your power amps, and thus of your entire system. The longer the cable, the more crucial the gauge. As a consequence, the user tends to turn up the power amp, which in turn can lead to speaker damage. You should use at least14-gaugecable—12-gaugeis ideal. Try to avoid using cables longer than 30 m (100 ft).

5.2Power amp performance

Choosing the right power amp can be difficult. The following rule of thumb may be helpful: the amp should provide about twice as much power as the speakers can handle. A speaker with a continuous power rating of 200 Watts should be driven by power amps with 400 Watts of output power.

5.3Fuses

We do not recommend the use of fuses for audio applications. Speakers can be damaged by high signal peaks or high output power. Fuses can only protect the speaker against one of these, but never against both. In addition, fuses can have nonlinear resistances, which can lead to distortion and unpredictable overdriving of the speakers.

5.3.1 Protecting your system

sExercise caution while setting levels and avoid overdriving your power amps.

sRespect the physical limits of your P.A. system.

sUse a limiter to limit the output level. Insert the limiter between the mixing console output and your power amp. Our proven compressors COMPOSER PRO MDX2200, AUTOCOM PRO MDX1400 and MULTICOM PRO MDX4400, all of which provide limiter functions, are ideal for this application. Used properly, they can eliminate overdriving of your audio signals and effectively suppress dangerous signal peaks.

+Our crossover network SUPER-XPRO CX3400, which features independent limiters on each individual output, can also be used to protect your system.
