1. CONNECTIONS

Connections

Two ¼ lo dspeaker inp ts are wired in parallel. Yo can alternatively connect one

of the connectors to the o tp t on yo r 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

lo dspeaker.

Two professional speaker inp ts (Ne trik® Speakon®-compatible) are wired in parallel.

The pin designation is pins 1+ and 1-. Yo can alternatively connect one of the

connectors to the o tp t of yo r 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 lo dspeaker.

2. POWER AMP RATING

The power rating of yo r amp sho ld be ro ghly 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

In the following example, the main o tp t signal of a mixing console is connected to a power

amplifier. Both the o tp ts and inp ts are stereo. A PA 252 is connected to each of the amp

o tp ts, and these speakers reprod ce the entire freq ency range (f ll range).

Full-range stereo operation
