2Description

2.1The 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

The Plena product range includes:

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

a charger

a loop amplifier

The various elements are designed to complement each other thanks to matched acoustical, electrical and mechanical specifications.

2.2Contents of box

The packaging box contains the following:

PLE-2CS Plena Two-zone Call Station

Cable terminated with a lockable Cat-5 connector

2.3The 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 preand 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.

2.4Controls, connectors and 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:

1Zone 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.

2Push-to-talk (PTT) button - A push-to-talk (PTT) button to start the business call.

3Status 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:

1Configuration 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.

2System 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.

3Rotary volume control - A rotary volume control (potentiometer) to set the output volume of the call station. See chapter 5.3.

4Connections and settings

4.1Connecting 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.
