Description  
The Plena Two-zone Call Station features:  
a selectable microphone gain level, a selectable  
speech filter, and a limiter for improved intelligibility  
a balanced line level output. See section 2.3.1.  
two loop-through RJ-45 sockets. See section 2.3.2.  
DIP switches and status LEDs. See section 2.3.3.  
a push-to-talk (PTT) button. See section 2.3.4.  
2.1  
The Plena product range  
The Plena Two-zone Call Station is part of the Plena  
product range. Plena provides public address solutions  
for places where people gather to work, worship, trade,  
or relax. It is a family of system elements that are  
combined to create public address systems tailored for  
virtually any application  
For a detailed description of all controls, connections  
and indicators, see section 2.4.  
The Plena product range includes:  
2.3.1 Balanced line level output  
The Plena Two-zone Call Station has a balanced line  
level output, giving it a maximum range of 200 m from  
the controller when using Cat-5 Ethernet cables.  
mixers  
mixer amplifiers  
preamplifiers  
power amplifiers  
a music source unit  
a digital message manager  
a feedback suppressor  
call stations  
an All-in-One system  
a voice alarm system  
a timer  
2.3.2 Loop-through RJ-45 sockets  
With the loop-through RJ-45 sockets, it is possible to  
daisy chain up to six call stations. The priority is  
automatic; the call station nearest to the mixer has  
priority and can override the call station further away  
from the mixer.  
a charger  
a loop amplifier  
2.3.3 DIP switches and status LEDs  
With the DIP switches at the base of the call station you  
can select different microphone gain levels, seven  
different chimes (any .wav file), define the speech filter  
and the momentary or latching speaking functions.  
Two LEDs on top of the call station show which zones  
have been selected. One additional LED gives visible  
feedback on the active state of the microphone and the  
system:  
The various elements are designed to complement each  
other thanks to matched acoustical, electrical and  
mechanical specifications.  
Contents of box  
The packaging box contains the following:  
PLE-2CS Plena Two-zone Call Station  
Cable terminated with a lockable Cat-5 connector  
green flashing: microphone is standby (chime is  
sounding)  
green continuous: microphone is active  
off: a call is being made by a higher priority call  
station  
2.3  
The Plena Two-zone Call  
Station  
The Plena Two-zone Call Station is a modern, high-  
quality call station with a stable metal base design, a  
flexible microphone stem and a unidirectional  
condenser microphone. It can make calls to selected  
zones (zone one or two) in a public address system built  
with the PLE-series two-zone mixer and mixer  
amplifiers.  
2.3.4 PTT button  
To the PTT button, a pre- and post chime can be  
assigned that is played at the start or at the end of the  
call. To this end, the call station is equipped with seven  
built-in chimes.  
In addition to tabletop use, the Plena design allows neat  
flush-mounting in desktops.
