Connections
Two ¼ loudspeaker inputs are wired in parallel You can alternatively connect one of the
connectors to the output on your power amp and tap into the signal from the amp once
again on the second connector, in order to feed this signal into an additional loudspeaker
¼" TS connector
+ATTENTION: Never connect more than one power amp output to the

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
Zges to e handled y the power amp can e calculated, as shown elow,
from the individual impedance values of the connected speakers:
Your amplifier may e damaged if the actual impedance drops elow its
input impedance. Please make sure that the calculated total impedance
Zges 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
