Plena Power Amplifier | Installation and User Instructions | Connections and settings
Connect speakers to the 70 V, the 100 V or the 8 Ohm
terminals on the Euro style pluggable screw terminal
connector (6) at the rear of the unit.
Constant voltage loudspeakers
figure 4.3: Connecting speakers
The power amplifier can drive 70V and 100 V constant
voltage loudspeakers. The 100 V connection in shown
in figure 4.3.
Connect the loudspeakers in parallel and check the
loudspeaker polarity for in-phase connection. The
summed loudspeaker power should not exceed the
rated amplifier output power.

Low impedance loudspeakers
figure 4.4: Connecting speakers
Connect low impedance loudspeakers to the 8 Ohm/0
terminals. This output can deliver the rated output
power into an 8 Ohm load. Connect multiple
loudspeakers in a series/parallel-arrangement to make
the combined impedance 8 Ohm or higher. Check the
loudspeaker polarity for in-phase connection.
