EUROPOWER EP1500/EP2500

Examples:
Driving a single 8-Ohm loudspeaker. =
Driving a single 4-Ohm loudspeaker. =
Mono-bridged modeFig. 3.5:
DIP switch positions for mono-bridged modeFig. 3.6:
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 approp-
riate volume level is applied.
Caution
2-Ohm loads should never be applied when in mono- +
bridged mode.
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.
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.
Bi-amping3.2
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 amplies the lows and channel 2 amplies
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.
A stereo signal can also be split up analogous to the example
described above. However, to do that you need two 2-way spea-
kers 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 ask 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 g. 3.4). The amp’s input lters 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 lter for the subwoofer signal should be set at 30 Hz.
The BEHRINGER EUROLIVE SERIES loudspeakers are an out-
standing solution for expanding your P.A. system, because each
frequency range/application has a speaker type that optimally
suits its characteristics.
Extreme clip limiter settings in bi-amp operating mode +
can result in balance shifting.
