Introduction   Thanks to its numerous features, the EUROLIVE PROFESSIONAL SERIES is the   ideal PA loudspeaker system: it is equally well-suited both for small gigs and   large stages. We have brought it to life in order to offer you a complete range   of loudspeaker choices. In doing so, we have left open all the options for   expanding your PA system. All loudspeakers feature professional inputs and   outputs (compatible to Neutrik Speakon), letting you flexibly expand your setup   whenever you need to.   ◊ The following instructions are intended to familiarize you with the   specialized terminology used throughout this user’s manual, so that   you can master all the functions. After having thoroughly read the   user’s manual, store it in a safe place for future reference.   Fig. 1.2: Subwoofer connector panel (B1800X PRO)   The EUROLIVE PROFESSIONAL SERIES features professional speaker connectors   (compatible to Neutrik Speakon) that assure problem-free operation.   The Speakon connector was developed for loudspeakers with high power ratings.   If it is connected into the corresponding plug, it locks into place and cannot   accidentally be disconnected. It protects against electric shock and assures   correct polarity. Each of the plugs only carries the assigned individual signal   (see table 4.1/Fig. 1.3 and the insignia on the back of the unit).   1.1 Before you get started   1.1.1 Shipment   Your EUROLIVE speakers were carefully packed at the assembly plant to assure   secure transport. Should the condition of the cardboard box suggest that damage   may have taken place, please inspect the unit immediately and look for physical   indications of damage.   Professional speaker connector   (compatible with Neutrik Speakon connectors)   ◊ Damaged units should NEVER be sent directly to us. Please inform the   dealer from whom you acquired the unit immediately as well as the   transportation company from which you took delivery of the unit.   Otherwise, all claims for replacement/repair may be rendered invalid.   ◊ ◊ ◊ Please always use the original packaging to avoid damage due to   storage or shipping.   Never let unsupervised children play with the EUROLIVE speakers or   their packaging.   front view   rear view   Fig. 1.3: Speakon connector   Please dispose of all packaging materials in an environmentally   friendly fashion.   Please only use the commercially available Speakon cables (type NL4FC)   to connect your loudspeakers to the power amp. Verify the pin assignment   of your loudspeakers and cables depending on the loudspeaker output you   are using.   1.1.2 Initial operation   Your EUROLIVE speakers are connected to a power amplifier using the speaker   connectors located in the back. Please read ch. 5, “Additional Considerations”   and ch. 6, “Application Examples” to get important technical information and   practical suggestions about use.   1.1.3 Online registration   Please register your new BEHRINGER equipment right after your purchase   warranty carefully.   ◊ Always make sure to mute your power amplifier before connecting   the speakers.   Should your BEHRINGER product malfunction, it is our intention to have it   repaired as quickly as possible.

Another option is to use raised stands, which prevent the speakers from   having a direct contact with the ground.   This user’s manual is structured in such a way to give you an overview about the   application options of your EUROLIVE PROFESSIONAL speakers, giving you at the   same time important information about optimizing your PA system. Should you   require detailed explanations about specific subjects, please visit us on the   internet at behringer.com.   2.4 Loudspeaker protection by using   a low-cut filter   Try to prevent damage to your speakers caused by extreme oscillation of the   bass membrane due to subsonic noise and extremely deep frequencies. Use an   equalizer to cut off those frequencies that fall below your speakers’ frequency   range, or use a low-cut/high-pass filter. Most equalizers and sound-improvement   systems offer a low-cut function, like the BEHRINGER ULTRAGRAPH DIGITAL   DEQ1024, for example.   2. Optimal Operation   We have developed the EUROLIVE PROFESSIONAL SERIES for use in a wide range   of possible applications. Of course, the sound of your loudspeakers depends on   the acoustic characteristics of the room/space in which they are being used.   The following chapters of this manual will give you information about getting   the most out of your EUROLIVE speakers.   Using a low-cut filter in your signal path is particularly recommended if you   use record players or CD players as your signal source. CD players often produce   extremely deep frequencies, which can lead to extreme excursions of the   bass membrane.   2.1 HF drivers   High frequencies are the segment of the audio spectrum responsible for clarity   and speech intelligibility. These frequencies are the easiest ones to locate,   but at the same time they are also the easiest ones to “obstruct.” Therefore,   we recommend positioning your speakers so that the HF drivers are located   slightly above the height of the audience. This guarantees the best possible   dispersion of high frequencies and a considerably higher intelligibility.   3. Operating Modes   3.1 BI-AMPING and PASSIVE operation   (B1800X PRO)   The EUROLIVE PROFESSIONAL SERIES subwoofer can run in two ways: in PASSIVE   and BI-AMPING mode. The B1800X PRO can be switched from BI-AMPING   to PASSIVE by using the switch located in the back. For all applications,   your EUROLIVE speakers are connected using the speaker inputs.   2.1.1 Directional pattern of asymmetrical HF drivers   An outstanding feature of the B1220 PRO, B1520 PRO and the B2520 PRO are their   asymmetrically formed horns (“Asymmetrical Dispersion Constant Directivity   Horn”). By turning the horns 90°, you can optimize the directional pattern for   both vertical and horizontal speaker positioning. The default horn setting is the   “front of house” vertical configuration, whereby the wide dispersion side (100°) is   pointed downward and the narrow dispersion side (50°) is pointed upward. If you   want to position your speaker horizontally (as a “floor” monitor), you can modify   the horn position to assure optimal dispersion   ◊ Never switch the operating mode if your EUROLIVE speakers are wired   to an active signal source.   The subwoofer features an internal crossover. Running the B1800X PRO in passive   mode makes it ideally suited for working together with the 2-way B1220 PRO,   B1520 PRO and B2520 PRO systems. This way, you achieve an absolutely balanced   sound characteristic. However, if you select the BI-AMPING mode, your subwoofer   can be combined with other EUROLIVE 2-way systems. The BI-AMPING operating   mode offers several primary advantages: lower distortion, greater flexibility of   signal transmission as well as an improved overall performance of your system.   The PASSIVE operating mode has the advantage of requiring no additional   crossovers in order to keep the subwoofer’s frequency range within its limits.   (turning the horn by 90°). Please do the following:   (1) Remove the speaker cover by carefully and uniformly pulling off the   steel grill.   (2) Unfasten the four screws with which the horn is mounted.   (3) Turn the horn 90°, so that the wide dispersion side (100°) points upward   If you are using an external crossover, e.g. the BEHRINGER ULTRADRIVE PRO   DCX2496, pay attention to chapter 8, “Specifications.” There, you will find   information about the recommended crossover frequency range. We recommend   a slope rate of at least 12 dB, whereby a higher value guarantees the best possible   performance. A slope rate of 24 dB is ideal.   when the loudspeaker is lying horizontally on its side.   (4) Mount the horn back into its place with the four previously   unfastened screws.   (5) Set the grill back into its place and press gently until it snaps into position.   Our recommendations are only examples of possible interactions between   different EUROLIVE speakers. Depending on your own personal sound   requirements and the genre of the music being played, other combinations are   of course possible.   ◊ No warranty claim is valid for damage caused by incorrect handling   or flawed and/or careless use.   2.2 How to prevent feedback   Always place the “front of house” speakers ahead of the microphones   (from the audience’s perspective), and never behind. Use professional floor   monitors (e.g. B1220 PRO, B1520 PRO or B2520 PRO) or an in-ear monitoring   system to hear the stage performers.   3.2 Looping through the subwoofer signal   (B1800X PRO)   The B1800X PRO subwoofer from the EUROLIVE PROFESSIONAL SERIES features   two speaker connectors. In BI-AMPING mode, the PINS 2-/2+ of the input are   connected directly with the speaker. PINS 1-/1+ of the input are connected to   the PINS 1-/1+ of the output and the signal can be simply looped through. To this   end, please adhere to the specifications given in chapter 4.   2.3 How to avoid feedback when working with   record players (DJ Applications)   In applications with record players, bass feedback can occur. Bass feedback   occurs when low frequencies get back to the pickup and are re-reproduced on   the speakers. The most common causes for this are: speakers located too closely   to the record player, a room with a wooden floor, or presence of a podium or a   platform. In such cases, it is best to move the speakers away from the record   ◊ Please keep in mind that when you switch the B1800X PRO subwoofer   to BI-AMPING mode, the input signal is routed to PINS 2-/2+. In this   case, PINS 1-/1+ merely serve to loop the signal through!   Download from Www.Somanuals.com.

You can alternatively connect one of the   connectors to the output on your power amp and tap into the signal from the   amp once again on the second connector, in order to, for example, feed this   signal into an additional loudspeaker. This way, you can create stacks consisting   of speakers with different impedance values.   5.3 Fuses   We do not recommend the use of fuses with audio applications. Damage to   loudspeakers can be the result of high peak signals and high output power.   However, fuses can only offer protection from one of these two factors, and never   from both. Additionally, fuse resistors are sometimes nonlinear, leading to   distortion and unpredictable overdriving.   5.3.1 Protecting your equipment   ◊ ATTENTION: Never connect the output signals of different power   amps to both parallel inputs at the same time. This may permanently   damage your setup.   • • • Always try to find the optimal signal level. Try to avoid overdriving your amp   keep in mind the physical limitations of your PA system   Use a limiter to restrict the output signal level. Place the limiter between the   mixing console and the power amp. For this purpose, our proven AUTOCOM   PRO-XL MDX1600, COMPOSER PRO-XL MDX2600 and MULTICOM PRO-XL   MDX4600 compressors offer an outstanding solution. All models can be used   as a limiter: the audio signal doesn’t overdrive any more, and unpleasant   “peaks” are effectively avoided   4. Pin Assignment (B1800X PRO)   Subwoofer B1800X PRO   PINS 1-/1+   PINS 2-/2+   INPUT: Full-range input   OUTPUT: highpass output   ◊ Our ULTRADRIVE PRO DCX2496 and SUPER-X CX3400/CX2310 crossovers   are particularly well-suited for protecting your equipment: for each   output, they have independent limiters.   PASSIVE   Signal loop   BI-AMPING   Signal loop   Subwoofer input   Tab. 4.1: Pin assignment   6. Application Examples   4.1 Subwoofer (PASSIVE)   • Feed the full-range signal to the input PINS 1-/1+. The high-pass signal   can be tapped into at the output PINS 1-/1+. PINS 2-/2+ serve as a signal   loop through   6.1 Full-range stereo operation   In the following example, the main stereo output signal of a mixing console   is connected to a stereo power amplifier. A B1220 PRO is connected to each of   the amp outputs, and these speakers reproduce the entire frequency range   (full range).   4.2 Subwoofer (BI-AMPING)   • Connect the subwoofer signal to PINS 2-/2+   XENYX 1202FX   • PINS 1-/1+ of the input are connected to PINS 1-/1+ of the output, and can   be used to loop the signal through   • In general, when in BI-AMPING mode, PINS 1-/1+ and PINS 2-/2+ are   looped through   L R 5. Additional Considerations   5.1 Length and diameter of loudspeaker cables   Loudspeaker cables whose diameter is too small can limit the power amp   performance considerably. The longer the cable, the greater the problem. As a   result, musicians often simply “turn up” the amp, which can lead to loudspeaker   damage. Therefore, don’t use cables longer than 15 m (45 ft.). For most applications,   this will not be necessary. Cable diameter should be at least 2.5 - 4.0 mm2.   EUROPOWER EP2000   5.2 Power amp rating   Selecting the right amp can turn out to be rather difficult. Therefore, stick to the   following rule of thumb: the power rating of your amp should be roughly twice   the speaker load capacity. A speaker rated at 400 Watts continuous performance   can easily be powered by an amp rated at 800 Watts output power. An optimal   addition to your speaker system would be the BEHRINGER EUROPOWER EP2500   power amp, for example.   2 x EUROLIVE PROFESSIONAL B1220 PRO   Fig. 6.1:Full-range stereo operation   Download from Www.Somanuals.com.

Troubleshooting   7.1 No signal when loudspeaker is connected   7.4 Treble signal too low   • Check the EQ settings on your mixing console or on an external EQ,   if applicable   • Make sure that your mixing console is indeed carrying a signal (is the master   fader raised? Are channels active?) and that the gain control on your amp is   turned up   • Make sure that the tweeters on your loudspeakers are positioned at the   same height as the ears of the people in the audience. If not, please modify   the speaker position   • • When using a crossover, make sure that the relevant channels are active   • The internal tweeter fuse may have opened. In this case, please contact a   BEHRINGER service branch office near you   Check if the cable connection is interrupted/damaged somewhere in   your setup   7. 5 Bass signal too low   • • To test your configuration, connect another amp. If you now get a signal,   the power amp is the culprit   • Check the EQ settings on your mixing console or on an external EQ,   if applicable   To test your configuration, connect another speaker. If you now get a signal,   the fault lies within the speaker   • Check the speaker cable pin assignment (see fig. 1.3). Incorrect pin   assignment can cause phase cancellation and the frequency incursions   related to it   7. 2 Signal present only on one channel   • Make sure that your mixing console is working properly (is the signal present   on both outputs (L/R)?)   7.6 Poor sound characteristics   • Check the speaker cable pin assignment (see fig. 1.3). Incorrect pin   assignment can cause phase cancellation and the frequency incursions   related to it   • • If using a crossover, check if the relevant channel is active   Check if the cable connection to the silent channel and to the corresponding   speakers is interrupted/damaged somewhere along the path   • Check if large objects (e.g. effect racks and similar equipment) are placed   in front of the loudspeakers. They too can negatively influence   sound dispersion   • Connect the silent loudspeaker onto the amp channel that works properly.   If you now get a signal, it is the amp channel that is at fault. If you still   can not hear anything, the fault lies either within the loudspeaker or the   cables used   • • Check the sound quality of the input signal by listening to it on a set   of headphones   7. 3 Signal distorted   Also see the instructions in the chapters 7.3, 7.4 and 7.5   • Make sure that all signals on the mixing console have been set to optimal   levels in order to avoid distortion   • • If using a crossover, check if all signals have been set to correct levels   Make sure that the power amp channels are not overdriving. If so, turn the   gain control down a little. However, it could also be the case that your power   amp doesn’t have enough power headroom, so that the required volume can   not be generated without starting to distort   • • • Make sure that the level of the signal getting into the speakers is not too   high, causing distortion   Check your EQ settings. Excessively increasing the frequencies can result   in distortion   If distortion is still occurring despite everything you have tried to eliminate   it, try connecting a different power amp. If you no longer hear distortion,   its cause was with the power amp   • • As a test, connect another speaker.
