EUROLIVE S1020/S1220/S1220F/S1520/S1530/S1800S

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 Ztotal 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 Ztotal is not smaller than specified.

4.1Full-range stereo operation

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 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).

4.2Two-way stereo operation with subwoofers

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 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.
