1. INTRODUCTION  
By purchasing one of the BEHRINGER EUROPOWER amp-  
lifiers, you have selected a piece of high-end gear. This unit was  
developed for professional use in live applications, and its rich  
list of features will make it a dependable part of your equipment  
with a diverse set of possible uses.  
We are often asked how we manage to produce such high-  
quality devices at such unbelievably low prices. The answer is  
quite simple: it’s you, our customers! Many satisfied customers  
mean large sales volumes enabling us to get better purchasing  
terms for components, etc. Isn’t it only fair to pass this benefit on  
to you? Because we know that your success is our success  
too!  
The EUROPOWER amps feature for example an input filter for  
each channel, enabling you to remove the disturbing low-  
frequency portion of the signal. Additionally, there is a limiter that  
protects your loudspeakers. Various operating modes, such as  
parallel or mono mode, open up various possibilities for effective  
implementation with the rest of your audio equipment, leaving no  
wishes unanswered.  
I would like to thank all of you who have made the EUROPOWER  
power amplifiers possible. You have all made your own personal  
contributions, from the developers to the many other employees  
at this company, and to you, the BEHRINGER user.

1. INTRODUCTION  
EUROPOWER EP1500/EP2500  
If the unit is damaged, please do NOT return it to  
BEHRINGER, but notify your dealer and the shipping  
company immediately. Otherwise, claims for damage  
or replacement may not be granted.  
+
Please make sure the unit is provided with sufficient ventilation,  
and never place your EUROPOWER amp on top of other heat-  
emanating equipment or in the vicinity of a heater to avoid the risk  
of overheating.  
ATTENTION!  
The mains connection is made via the enclosed power cord  
and a standard IEC receptacle. It meets all international safety  
certification requirements.  
+
We would like to bring your attention to the fact  
that extremely loud sound levels may damage your  
hearing as well as your loudspeakers. Please lower  
both GAIN controls leftwards before powering up  
the unit. Be sure to keep the volume at an  
appropriate level.  
+
Please make sure that all units have a proper ground  
connection. For your own safety, never remove or  
disable the ground conductor from the unit or the  
AC power cord.  
2. CONTROL ELEMENTS  
Since control elements of both the EP1500 and the EP2500 are identical, we have used the EP1500 as the model represented in the  
illustrations to assure simplicity.  
2.1 Front panel

The main switch is used to power up the amp.  
The CLIP LED lights up when the signal is distorted. Should  
distortion occur, reduce the input level, so that the CLIP  
LED stops lighting up.  
+
Please take note: Merely switching the unit off does  
not mean that it is fully disconnected from the  
mains. When not using the unit for prolonged  
periods of time, please unplug the unit’s power cord  
from the power outlet.  
The SIGNAL LED lights up as long as a signal is present  
at the input.  
The GAIN control (channels 1 and 2) is used for setting  
up the input gain.  
Ventilation openings are located at the front of the unit, so  
that hot air is prevented from being trapped inside the unit,  
thus causing faulty operation or even damage.  
The POWER LED lights up as soon as the unit is powered  
up.

EUROPOWER EP1500/EP2500  
+
To prevent faulty operation, please assure that the  
unit is kept at a distance from other appliances  
emanating heat.  
Switches 2 (ch. 1) and 9 (ch. 2) determine the cut-off frequency.  
As long as the filter is disengaged, frequencies below 5 Hz are  
cut to prevent damage.  
These are the Speakon® outputs (channels 1 and 2). When  
running the unit in mono-bridged mode (see chapter 2.3.5),  
please use the channel 1 output exclusively. For further  
information on Speakon® connectors please refer to  
chapter 4.1.  
You should set up the filters so they best suit the frequency  
response of your speakers, since some speakers (e.g. bass  
reflex speakers) are particularly sensitive to over-excursion  
below the listed frequency range.  
The 50 Hz filter should be engaged when using broadband  
speakers because the filter provides a moderate amplification in  
the 100-Hz range, resulting in a fuller sound. The 30 Hz filter is  
ideally suited for subwoofer operation as well as for broadband  
cabinets. The “Off” setting should be used only for special  
applications (e.g. studio applications), in which recognizing and  
subsequently removing infra-sound is important.  
These are the output terminals (channels 1 and 2). When  
running in mono, please make sure to use both middle  
connectors to connect your loudspeaker.  
BREAKER (automated fuse). After eliminating the cause  
of faulty operation, simply depress the BREAKER and  
power up the unit again. The BREAKER acts in place of  
common discardable fuses.  
2.3.3 2-channel mode (stereo)  
+
Attention: Before engaging the BREAKER switch,  
you should power down the unit (POWER switch  
set to OFF)!  
Both channels of your amp function independently from one  
another in this operating mode, and each has its own input signal.  
Two independent speakers are connected at the outputs. To  
activate this operating mode, please set the MODE SWITCHES  
4 and 5 to “STEREO”.  
Power is supplied via an IEC connector. The matching  
cable is provided with the unit.  
+
When running the unit in two-channel mode, the  
switches for mono-bridged mode must be  
disengaged (dip switches 6 and 7 in left position).

2.3.4 Parallel mode  
Here you can find a detailed overview of the individual  
Running in parallel mode enables you to feed a signal via one  
of the inputs into both outputs. Each channel drives its own  
loudspeaker with independent amplification, filter and limit  
characteristics. To link the inputs, set the MODE SWITCHES 4  
and 5 to “PARALLEL INPUTS”.  
MODE SWITCHES functions (  
).  
2.3 Configuration switches (MODE SWITCHES)  
+
Mono-bridged mode switches must be dis-  
engaged when running in parallel mode.  
With inputs set to parallel, you can use the remaining input  
connectors to feed the signal into additional amplifiers. This  
means that the channel 2 inputs function as outputs.  
The parallel mode is well-suited for applications in which driving  
two speakers with the same signal but with separate amplification,  
filter and limiter settings is desired.  
2.3.5 Mono-bridged mode  
This operating mode enables you to add up the respective  
voltage of both channels and use it to drive a single loudspeaker.  
The voltage is therefore doubled, the peak power is quadrupled,  
and program power is roughly three times as high as that of the  
individual channels. The input, output, gain, filter and limiter  
controls belonging to channel 1 are used when running in mono-  
bridged mode. The controls belonging to channel 2 are not used.  
To prevent signal cancellation due to internal phase inversion,  
the GAIN control belonging to channel 2 must be turned to its left-  
most position.  
Fig. 2.3: DIP-switches  
2.3.1 Clip limiter  
When the input signal connected to your amp is too high, you  
end up with a distorted output signal. To prevent this, both  
channels of your EUROPOWER feature a clip limiter that can be  
engaged or disengaged selectively. The limiters automatically  
recognize distortion and lower amplification until distortion is  
reduced to a tolerable level. To preserve the dynamic  
characteristics of the signal when low distortion levels are  
occurring, the clip limiters function with moderate suppression.  
Use switches 1 (ch. 1) and 10 (ch. 2) to activate the clip limiters.  
Use this operating mode to route the power from both channels  
to a single 8-Ohm or 4-Ohm load. To do so, set up the switches  
6 and 7 to “BRIDGE MODE ON”. To use the binding posts as your  
output, you MUST use the two middle posts only.  
When using broadband loudspeaker systems, the clip limiter  
reduces high frequency distortions which occur when an  
amplifier is overloaded. The drivers are thus protected from  
being damaged.  
+
The mono-bridged mode puts added demands on  
amplifier and speakers. Excessive distortion may  
occasionally completely mute the amp’s outputs  
as well as cause permanent damage to the  
speakers. Please assure that your speakers  
(minimal impedance 4 Ohms) as well as the cables  
used can handle the extra power generated in this  
mode.  
2.3.2 Input filter  
The LF (high-pass) filter removes frequencies below 30 and  
50 Hz respectively. The reproduction of the signal’s bass portion  
is thus optimized, since ultra-low, distracting frequencies are  
eliminated, and more power is available for the reproduction of  
the wanted segment of the signal. Engaging and disengaging the  
filters is done by using the switches 3 (ch. 1) and 8 (ch. 2).

2. CONTROL ELEMENTS  
EUROPOWER EP1500/EP2500  
3. APPLICATIONS  
+
Running EUROPOWER amplifiers in conjunction with  
8-Ohm speakers with a power rating of at least 2 x  
260 Watts (EP1500) and 2 x 450 Watts (EP2500) is  
recommended to assure optimal operation.  
3.1 Differences between 2-channel, parallel  
and mono-bridged operating modes  
2-channel mode is the most common operating mode of  
amplifiers. Both channels operate fully independently from one  
another. There is always a separate input signal as well as a  
separate output signal.  
Fig. 3.2: DIP switch positions for 2-channel operation  
Examples:  
Parallel mode is identical to 2-channel mode, except for the  
inputs of both channels are internally connected in parallel. One  
input signal routes parallel both channels, while their filters etc.  
are independently controlled.  
s
s
2-channel (stereo) playback  
Two independent mono signals, e.g. instrument signal and  
monitor mix  
Examples:  
s
Bi-amp operation, whereby bass frequencies are run on  
channel 1, and high frequencies on channel 2 (see chapter  
3.2, “Bi-amping”).  
s
A mono signal is fed into both channels, whereby amplifi-  
cation of each channel is controlled separately.  
s
Parallel mode (as described above) with connection of an  
additional amp via the remaining free input connector. The  
input signal is present there, and may be connected to  
further equipment.  
+
When connecting a balanced input signal, please  
make sure to exclusively use balanced cables for  
passing the signal further on. Otherwise, a single  
unbalanced cable can turn the entire signal  
unbalanced.

+
+
When the amp is overdriven for longer periods of  
time, the output signal may occasionally be muted  
for several seconds. In certain situations,  
excessive overdriving may trigger off the  
automated fuse. To avoid overdriving the amp,  
please continually make sure that an appropriate  
volume level is applied. CAUTION: 2-Ohm loads  
should never be applied when in mono-bridged  
mode.  
When running in mono-bridged mode, the voltage of both  
channels is added up and fed into a single loudspeaker system.  
There is one input and one output signal respectively, and only  
the controls of channel 1 (and not of channel 2) are used.  
+
However, should the DIP switches 4 and 5 still be  
in PARALLEL INPUTS position while in mono-  
bridged mode, the signal on the free input (input  
channel 2) can be forwarded to an additional amp.  
When connecting a balanced input signal, please  
make sure to exclusively use balanced cables for  
passing the signal further on. Otherwise, a single  
unbalanced cable can turn the entire signal  
unbalanced.  
Examples:  
s
s
Driving a single 8-Ohm loudspeaker.  
Driving a single 4-Ohm loudspeaker.  
Safety precautions for mono-bridged  
operation  
Running your amp in mono-bridged mode can quickly  
result in excessive overdriving and premature shutting  
down of the unit itself. In the worst-case scenario, your  
loudspeakers may be damaged permanently. Therefore,  
you should always make sure that the speakers you use  
can indeed handle the power load fed into them.  
A voltage of up to 100 V RMS is present between the  
output connectors of the EP2500. Always implement  
appropriate safety precautions when connecting your  
speakers to avoid the risk of electric shock.  
3.2 Bi-amping  
By using an active crossover, you can divide up the frequency  
range into several bands. For example, in doing so you can split  
a mono signal into upper-frequency and lower-frequency ranges.  
These two signals can then be hooked up to the inputs of your  
amp, so that channel 1 amplifies the lows and channel 2 amplifies  
the highs (2-channel operation). The outputs are connected to a  
2-way speaker, whereby the output signal 1 drives the woofer  
and output signal 2 runs the drivers. Of course, you can use two  
separate speakers instead of a single 2-way speaker.  
Fig. 3.5: Mono-bridged mode  
A stereo signal can also be split up analogous to the example  
described above. However, to do that you need two 2-way  
speakers or 4 separate speakers, two EUROPOWER amps and  
an active 2-way stereo crossover. The BEHRINGER SUPER-X  
PRO CX2310 is optimally suited for this task and offers  
additionally a single mono-subwoofer output. By deploying a  
third EP1500 amp (preferably in mono-bridged mode) and a  
subwoofer, you have a perfect setup that adds a low-frequency  
system to the stereo bi-amp application (see fig. 3.4). The amp’s  
input filters for the high/mid-frequency ranges should in this  
case be engaged and set at 50 Hz. To remove low, disturbing  
frequencies from the signal, the input filter for the subwoofer  
signal should be set at 30 Hz.

3. APPLICATIONS  
EUROPOWER EP1500/EP2500  
The BEHRINGER EUROLIVE SERIES loudspeakers are an  
4. INSTALLATION  
outstanding solution for expanding your P.A. system, because  
each frequency range/application has a speaker type that  
optimally suits its characteristics.  
Your EUROPOWER can be installed into a 19" rack and requires  
two rack units. Please use four attaching screws and washers  
for installation. Reinforce the back end, especially for on-the-  
road use. Please assure that enough cool air reaches the rack,  
especially when other rack equipment emanates a lot of heat. In  
the case of the EUROPOWER EP1500 and EP2500, hot air  
circulates at the front of the unit to thermally relieve the rack  
enclosure.  
+
Extreme clip limiter settings in bi-amp operating  
mode can result in balance shifting.  
+
Fan speed adjusts automatically and assures safe  
operation. Never block ventilation openings. Should  
internal temperature reach extreme values, the  
unit will shut down automatically.  
4.1 Connections  
Inputs  
Each channel features balanced XLR and 1/4" TRS stereo jack  
inputs, with input impedances of 20 k(balanced) and 10 kΩ  
(unbalanced). In general, balanced signals cause less noise  
than unbalanced signals.  
For balanced input signals, use the XLR and 1/4" TRS stereo  
inputs. For unbalanced input signals, use the unused pin of the  
XLR connector with grounding. No alteration is necessary on  
mono jack connectors (see plug type illustrations on page 10).  
+
Should you register distractive signals such as  
noise or hissing, we recommend separating the  
amp input from the signal source. This way, you  
can quickly determine if the noise originates in  
the equipment connected to the amp. Always  
make sure to completely lower amplification of  
both channels before powering up the amp (GAIN  
control turned all the way leftward). Otherwise,  
permanent damage to your speakers may occur.  
Outputs  
Your EUROPOWER offers several output connection possi-  
bilities: two Neutrik NL4MD Speakon® connectors and two pairs  
of touch-safe binding posts. The Speakon® connectors were  
especially developed for driving high-power speakers. They snap  
in securely, prevent electric shock and assure correct polarity.  
The upper Speakon® connector drives either one or both channels,  
and is therefore well-suited for mono-bridged operation (1+/2+).  
The lower connector carries the signals from channel 2 only.  
Fig. 4.1: Speakon® connectors  
Fig. 3.7: Stereo bi-amp mode with a separate subwoofer  
+
Whenever possible, use thick and short speaker  
cables to minimize power losses. Never lay out  
output cables near input cables.

EUROPOWER EP1500/EP2500  
4.1.1 Using the binding posts  
4.2 Audio connections  
To connect the loudspeakers to the amplifier’s binding posts,  
please do the following:  
Various cables are needed for different types of applications.  
The following illustrations show the correct wiring. Always use  
high-grade cables.  
1.  
Switch off the amp and disconnect it from the mains (unplug  
mains connector).  
+
When connecting a balanced input signal, please  
make sure to exclusively use balanced cables for  
passing the signal further on. Otherwise, one  
single unbalanced cable can turn the entire signal  
unbalanced.  
2.  
Remove the protective plastic covers shielding the binding  
posts by loosening the two screws on the right-hand side  
of the connections and lift the plastic cover upwards.  
3.  
4.  
Attach the terminal of your loudspeaker cable to the corres-  
ponding binding post.  
Place the protective plastic covers into its original upright  
position on each binding post and replace the two screws.  
Never operate the device without the protective plastic  
covers in place!  
Fig. 4.2: XLR connections  
Fig. 4.3: 1/4" TS connector  
Fig. 4.4: 1/4" TRS connector  
Fig 4.2: Protective plastic covers shielding the binding posts  
When using binding post connectors, please make sure that  
insulation on cables is not removed too high. Insert the naked  
part of the cable fully so that no metal is visible. Cable clamps  
must be isolated to avoid the possibility of electric shock. When  
running the amp in mono-bridged mode, always use the middle  
two binding post connectors, paying attention to correct polarity.  
+
ATTENTION! If you notice naked cable endings on  
the binding post connectors, do not power up the  
amp because of the risk of electric shock.  
4.1.2 Connecting to the mains  
Always connect your EUROPOWER amplifier to the voltage  
specified on the rear of the device. Connecting the amp to an  
incorrect voltage can permanently damage your amp.  
Before powering up the amplifier, double-check all  
connections and fully lower the gain setting.
