2. POWER AMP RATING
The power rating of your amp should be roughly twice the speaker load capacity.
ATTENTION!
+
When several loudspeakers are wired in parallel the overall impedance
Z
ges
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 its
input impedance. Please make sure that the calculated total impedance
Z
ges
is not smaller than the minimum impedance specified for your amplifier.
3. WIRING
Using an external (active) crossover, the main output signal of a mixing console is split into
a stereo signal and a mono signal. The mono signal covers the lower frequency range and
the stereo signal covers all other frequency ranges. Then, the stereo signal is connected
to a stereo power amplifier. A high-to-mid-range box is connected to each of the amp
outputs. The mono subwoofer signal is connected to one channel of an additional power
amplifier, which powers one PA 18 ECO subwoofer.
