3.4.8 Loudspeakers
Loudspeakers are connected via screw terminals,
behind a removable plastic cover for safety. This Plena
System Amplifier has a very flexible output
configuration, allowing for different groups of
loudspeakers.
• Connect 100 V-loudspeakers for zone 1 to the
100 V-/0-terminals of zone 1. The selection button
and the output attenuator for zone 1 (both on the
front panel) control this output. If a low impedance
loudspeaker is used for zone 1, connect it to the 8
Ohm- / 0-terminals of zone 1, but now the output
level will not be affected by the attenuator.
• Proceed in the same way for zone 2.
• Connect 100 V-loudspeakers that should receive
only priority announcements from microphone 1 to
the Call Only 100 V- /0-terminals. For this, the
priority mode must be enabled (see section 3.4.6).
The Call Active terminals provide voltage free relay
contacts. This contact is closed as long as a priority call
is active. This contact may be used for overriding
remote volume controls or other purposes. It is switched
together with the Call Only loudspeaker zone.

Note
Ensure that the loudspeakers are wired in phase
by connecting the 0-terminals of the
loudspeakers in the same zone together to the
amplifier 0-terminall.
Caution
Connect 100 V-loudspeakers in the same zone
just in parallel, but take care that the total power
of the
loudspeakers, i.e. the load, does not exceed the
120 W power rating of this Plena unit.
Caution
It is not recommended to use both low
impedance loudspeakers and 100 V-
loudspeakers simultaneously. Multiple low
impedance loudspeakers should be connected
in series or parallel so that the total impedance
is more than 8 Ohms.
