Communications Systems | LBB 1946/00 Plena Six-zone Call Station

The Plena Six-zone Call Station is a stylish, 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 (one to

six and all-call) in a public address system built around

the LBB 1925/10 system pre-amplifier. In addition to

tabletop use, the special design enables the unit to be

neatly flush-mounted in desktops.

Functions

This call station features selectable gain, a selectable

speech filter, and a limiter for improved intelligibility. The

call station has a balanced line level output, making it

possible to position it up to 100 m away from the

LBB 1925/10, using extension cables.

Dipswitches on the bottom of the call station configure

different pre and post-call chimes, as well as the priority

level. LEDs on the call station indicate selected zones, and

an additional, two-color LED gives visible feedback on the

active state of the microphone and the system. Green

indicates microphone on or chime active (flashing LED);

amber indicates that the system is occupied by a source

with a higher priority or operation error (flashing LED).
