Power amp rating3.
The power rating of your amplier 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 ampliers.
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 amplier may be damaged if the actual impedance
drops below the minimum impedance specied for your
amplier. Please make sure that the calculated total
impedance Z
total
is not smaller than specied.

Full-range stereo operation4.1
This application is for the full-range loudspeakers S1020, S1220,
S1220F, S1520 and S1530.
In the following example, the main output signal of a mixing console
is connected to a power amplier. 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).

Two-way stereo operation with subwoofers4.2
This application is for the subwoofer S1800S in combination
with the full-range speakers S1020, S1220, S1520 and S1530.
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 amplier. A loudspeaker is connected to each of the
amplifers outputs. The low-frequency signal is connected to an
additional power amplier, which powers the subwoofers.
