2.3 The Plena Two-zone Call
Station
The Plena Two-zone Call Station is a modern, highquality 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.
In addition to tabletop use, the Plena design allows neat
flush-mounting in desktops.
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.
For a detailed description of all controls, connections
and indicators, see section 2.4.
2.3.1Balanced 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.
2.3.2Loop-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.
2.3.3DIP 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:
• 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
2.3.4PTT 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.

indicators
2.4.1Top side
See figure 2.1 for an overview of the controls and
indicators on the top side of the call station:
1 Zone selection buttons - Two buttons to select
the zones to which the business call is distributed.
Each button has a green LED, which indicates the
zone to which the business call is distributed.
2 Push-to-talk (PTT) button - A push-to-talk
(PTT) button to start the business call.
3 Status indicator - A LEDs that indicates the status
of the call station. See section 2.3.3.

2.4.2Bottom side
See figure 2.2 for an overview of the controls and
indicators at the bottom of the call station:
1 Configuration settings - A set of DIP switches to
configure the call station (by setting the microphone
gain level, the chime and the speech filter). See
section 4.2.
2 System sockets - Two redundant RJ-45 sockets to
connect the call station to the PLE-series two-zone
mixer or mixer amplifiers using Cat-5 Ethernet
cables. When the system requires more than 2 call
stations, the system sockets can be used to make
loop-throughs. See section 4.1.
3 Rotary volume control - A rotary volume
control (potentiometer) to set the output volume of
the call station. See chapter 5.3.

4Connections and settings
4.1 Connecting multiple call
stations
When the configuration requires more than one call
station, use the loop-through RJ-45 sockets on the call
stations to make loop-throughs.
Note
In such a daisy chain configuration the priority
is automatic; the call station nearest to the mixer
has priority and can override the call station
further away from the mixer. Call station
number 2 has priority over call station
number 3, etc. See figure 4.1.
4.2 Configuration settings
Use the DIP switches at the bottom of the call station to
set the chime, the momentary or latching speaking
function, the speech filter and the microphone gain. See
figure 4.2.
4.2.1Chime settings
See figure 4.2. DIP switches number 1, 2 and 3 are used
for setting the chime.
1 = ON-position, 0 = OFF-position.
