Optimal Operation3.

We have developed the B212XL/B215XL 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.

HF drivers3.1

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 considerably higher intelligibility.

How to prevent feedback3.2

Always place the “front of house” speakers ahead of the microphones (from the

audience’s perspective), and never behind. Use professional oor monitors or an

in-ear monitoring system to hear the stage performers.

How to avoid feedback when working with 3.3

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 reproduced on the speakers.

The most common causes for this are: speakers located too closely to the record

player, a room with a wooden oor, or presence of a podium or a platform.

In such cases, it is best to move the speakers away from the record player

and “banish” them from the stage, so that they are located on rm ground.

Another option is to use raised stands, which prevent the speakers from having a

direct contact with the ground.

Loudspeaker protection by using a 3.4

low-cut lter

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 o those frequencies that fall below your speakers’ frequency

range, or use a low-cut/high-pass lter. Most equalizers and sound-improvement

systems oer a low-cut function, like the BEHRINGER ULTRAGRAPH DIGITAL

DEQ1024, for example.

Using a low-cut lter 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.

Additional Considerations4.

Length and diameter of loudspeaker cables4.1

Loudspeaker cables whose diameter is too small can considerably limit the

power amp performance. The longer the cable, the more pronounced 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 14 - 12 gauge.

Power amp rating4.2

Selecting the right amp can turn out to be rather dicult. 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 200 Watts continuous performance

can easily be powered by an amp rated at 400 Watts output power. An optimal

addition to your speaker system would be the BEHRINGER EUROPOWER EP2000

power amp, for example.

Fuses4.3

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 oer protection from one of these two factors, and never

from both. Additionally, fuse resistors are sometimes nonlinear, leading to

distortion and unpredictable overdriving.

Protecting your equipment4.3.1

Always try to nd 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 oer an outstanding solution. All models can be used

as a limiter: the audio signal doesn’t overdrive any more, and unpleasant

“peaks” are eectively avoided.

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.
