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).
