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.
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.

2.3.1 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.

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.

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:
• 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

2.3.4 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.
