EUROLIVE SERIES

1. INTRODUCTION

Wi h he BEHRINGER EUROLIVE, you have acquired a firs -class P.A. loudspeaker sys em. You now own a

leas one componen of an expandable sys em ha gives you well-balanced, dis or ion-free reproduc ion of

your audio ma erial.

Wi h i s numerous fea ures, he EUROLIVE SERIES represen s an ideal P.A. loudspeaker sys em for a varie y

of applica ions, from churches and schools o clubs o larger venues. We designed he EUROLIVE SERIES o

provide you wi h a comple e range of speaker enclosures wi h consis en quali y plus all he op ions you need

o expand your P.A. sys em according o your needs, like pro-level Speakon® inpu s and ou pu s.

The rugged enclosures ensure ha your EUROLIVE speakers will wi hs and even he roughes handling on he

road. They are made en irely of high-grade, non-pollu ing, formaldehyde-free E1 MDF boards wi h mul i-glued

ongue-and-groove cons ruc ion. Your EUROLIVE enclosure was manufac ured in compliance wi h

BEHRINGERs s ringen quali y con rol sys em.

1.1 Before you begin

1. INTRODUCTION

EUROLIVE SERIES

2. OPTIMUM PERFORMANCE

The EUROLIVE SERIES was designed for use in a varie y of applica ions. Na urally, he sound of your speaker

enclosures largely depends on he acous ic proper ies of he environmen in which i is used. The following

poin s should help you ge he mos ou of your EUROLIVE speaker sys em.

2.1 HF driver

High frequencies are a crucial par of he audio spec rum, which ensures clear sound and speech in elligibili y.

Whereas hese frequencies are he mos easily loca ed, hey are also he firs o be acous ically blocked. We

herefore recommend ha you se up your speakers so ha he HF driver is si ua ed sligh ly above he heads

of he audience. This will ensure no only op imal dispersion of he high-frequency con en , bu also considerably

improved speech in elligibili y and clari y.

2.2 Avoiding feedback

Always place he fron -of-house speakers ( he enclosures facing he audience) in fron of he microphones.

Use professional floor wedges (e.g. EUROLIVE F1220 or F1520), so ha he performers on s age can hear

hemselves.

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

Turn ables of en produce low-end feedback: low frequencies are fed back o he pickup arm and car ridge and

reproduced again by he speakers. Common causes of low-end feedback are speakers se up oo close o he

urn able, rooms wi h a wooden floor or elemen s placed on he s age. In such cases, ry moving he speakers

away from he urn able or off he s age and placing hem on a solid suppor . Ano her possibili y is o moun he

enclosures on s ands, hus minimizing direc con ac be ween floor and speakers.

2.4 Protecting your speakers with a low-cut filter

Low-frequency rumble or ex reme low frequencies can lead o an excessive displacemen of he speaker

diaphragm and in urn o permanen damage. Using an equalizer or a low-cu /high-pass fil er o elimina e he

low frequencies below he response curve of he speaker can effec ively preven his. Mos equalizers and

sound enhancers provide a low-cu func ion (e.g. BEHRINGER ULTRA-GRAPH PRO GEQ3102).

The use of a low-cu fil er in he signal pa h is especially recommended when using urn ables and/or

CD players as signal sources. CD players of en produce ex remely low frequencies, which can lead o excessive

diaphragm displacemen .

3. OPERATING MODES

Wi h he excep ion of he B1020, all EUROLIVE SERIES mul i-way sys ems can be opera ed in wo various

modes: FULL-RANGE and BI-AMPING. The subwoofers can ei her be opera ed in ACTIVE (BI-AMPING) or

PASSIVE mode. Use he swi ch on he rear panel of he enclosure o selec he appropria e mode for your

applica ion (see chap er 3.3). In bo h modes, he speakers are connec ed using he Speakon® inpu s.

+Ne er change the operating mode while an audio signal is present.

3.1 FULL-RANGE operation

All EUROLIVE models are equipped wi h a buil -in passive crossover ne work, which ensures a smoo h ransi ion

be ween he individual frequency ranges in FULL-RANGE mode. This mode is par icularly sui able for applica ions

ha require only a small-scale se up, such as speech applica ions in churches and schools, sound reinforcemen

in small clubs e c.

3. OPERATING MODES

EUROLIVE SERIES

3.2 BI-AMPING operation

3.2.1 Ad antages

BI-AMPING gives you a number of impor an advan ages: lower dis or ion, grea er flexibili y of signal ransmission

and improved overall sys em performance.

3.2.2 Selecting the crosso er frequency

For opera ion wi h an ex ernal crossover ne work such as our BEHRINGER SUPER-X PRO CX2310, please

refer o chap er 6 SPECIFICATIONS for recommended crossover frequencies. We recommend using a slope

of a leas 12 dBhigher values will improve performance. A slope of 24 dB is ideal.

3.3 ACTIVE (BI-AMPING)/PASSIVE subwoofer operation

EUROLIVE SERIES subwoofers also fea ure an in egra ed crossover. Driven in passive mode, he B1500X

subwoofer perfec ly complemen s our mul i-way sys em B1020, resul ing in a compac , well-balanced and

sonically accura e sys em. If you wish o opera e your subwoofer in ac ive mode (swi ch o BI-AMPING), i can

be combined wi h vir ually any of he remaining EUROLIVE mul i-way sys ems.

+To ensure optimal performance in combination with the B1020, the polarity of the B1500X

subwoofer has been re ersed (180°) in the factory. For operation with any other EUROLIVE

multi-way enclosure, the loudspeaker polarity must be re ersed by qualified ser ice personnel.

We designed he B1800X as he perfec subwoofer for he EUROLIVE mul i-way enclosures B1220 and B1520.

Of course, he B1800X can also be opera ed ei her in passive or ac ive mode.

The foregoing recommenda ions are only in ended o demons ra e he in erac ion of various EUROLIVE enclosures.

You may, of course, combine enclosures as you like, depending on your personal preferences and applica ions.

3.4 Looping through subwoofer signals

All EUROLIVE SERIES subwoofers are equipped wi h wo parallel Speakon® connec ors. Pins 2-/2+ are

direc ly connec ed o he loudspeaker. Pins 1-/1+ can be used o loop signals hrough, while he high-pass

signal is presen on pins 1-/1+ (ou pu ). Please refer o he ins ruc ions in chap er 4.

+Please note that switching the EUROLIVE subwoofers to BI-AMPING mode mo es the input

signal of the loudspeakers to pins 2-/2+. In this case, pins 1-/1+ act as a loop-through!

sIn his opera ing mode, pins 1-/1+ are always looped hrough o pins 2-/2+.

5. WHAT ELSE SHOULD BE CONSIDERED?

5.1 Length and gauge of speaker cables

Low-gauge speaker cables can considerably reduce he performance of your power amps, and hus of your

en ire sys em. The longer he cable, he more crucial he gauge. As a consequence, he user ends o urn up

he power amp, which in urn can lead o speaker damage. You should use a leas 14-gauge cable12-gauge

is ideal. Try o avoid using cables longer han 30 m (100 f ).

5.2 Power amp performance

Choosing he righ power amp can be difficul . The following rule of humb may be helpful: he amp should

provide abou wice as much power as he speakers can handle. A speaker wi h a con inuous power ra ing of

200 Wa s should be driven by power amps wi h 400 Wa s of ou pu power.

5.3 Fuses

We do no recommend he use of fuses for audio applica ions. Speakers can be damaged by high signal peaks

or high ou pu power. Fuses can only pro ec he speaker agains one of hese, bu never agains bo h. In

addi ion, fuses can have nonlinear resis ances, which can lead o dis or ion and unpredic able overdriving of he

speakers.

5.3.1 Protecting your system

sExercise cau ion while se ing levels and avoid overdriving your power amps.

sRespec he physical limi s of your P.A. sys em.

sUse a limi er o limi he ou pu level. Inser he limi er be ween he mixing console ou pu and your

power amp. Our proven compressors COMPOSER PRO MDX2200, AUTOCOM PRO MDX1400 and

MULTICOM PRO MDX4400, all of which provide limi er func ions, are ideal for his applica ion. Used

properly, hey can elimina e overdriving of your audio signals and effec ively suppress dangerous signal

peaks.

+Our crosso er network SUPER-X PRO CX3400, which features independent limiters on each

indi idual output, can also be used to protect your system.
