3. POWER AMP RATING
The power rating of your amplifier should be roughly twice the
continuous speaker load capacity. A speaker rated at 200 Watts
continuous power 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 amplifiers.
ATTENTION!
+
When several loudspeakers are wired in parallel
the overall impedance Z
total
to be handled by the
power amp can be calculated, as shown below, from
the individual impedance values of the connected
speakers:
Your amplifier may be damaged if the actual
impedance drops below the minimum impedance
specified for your amplifier. Please make sure that
the calculated total impedance Z
total
is not smaller
than specified.

4.1 Full-range stereo operation
This application is for the full-range loudspeakers P1020, P1220,
P1220F, P1520 and P2520.
In the following example, the main output signal of a mixing
console is connected to a power amplifier. Both the outputs and
inputs are stereo. A full-range loudspeaker is connected to each
amp output, and these loudspeakers reproduce the entire
frequency range (full range).

4.2 Two-way stereo operation with subwoofers
This application is for the subwoofer P1800S in combination
with the full-range speakers P1020, P1220, P1520 and P2520.
Using an external (active) crossover, the main output signal of a
mixing console is divided into two signals. One signal covers the
lower frequency range and the other signal covers the mid-to-
high-frequency range. The recommended crossover frequency
is 200 Hz. Then, the mid-high frequency signal is connected to a
stereo power amplifier. A loudspeaker is connected to each of
the amplifers outputs. The low-frequency signal is connected to
an additional power amplifier, which powers the subwoofers.
